Pull ARM SoC fixes from Olof Johansson:
"The latest and greatest fixes for ARM platform code. Worth pointing
out are:
- Lines-wise, largest is a PXA fix for dealing with interrupts on DT
that was quite broken. It's still newish code so while we could
have held this off, it seemed appropriate to include now
- Some GPIO fixes for OMAP platforms added a few lines. This was
also fixes for code recently added (this release).
- Small OMAP timer fix to behave better with partially upstreamed
platforms, which is quite welcome.
- Allwinner fixes about operating point control, reducing
overclocking in some cases for better stability.
plus a handful of other smaller fixes across the map"

Without proper regulator support for individual boards, it is dangerous
to have overclocked/overvoltaged OPPs in the list. Cpufreq will increase
the frequency without the accompanying voltage increase, resulting in
an unstable system.
Remove them for now. We can revisit them with the new version of OPP
bindings, which support boost settings and frequency ranges, among
other things.

sched: Fix RLIMIT_RTTIME when PI-boosting to RT
The sun5i timer is used as the sched-clock on certain systems, and ever
since we started using cpufreq, the cpu clock (that is one of the
timer's clock indirect parent) now changes as well, along with the
actual sched_clock() rate.
This is not accurate and not desirable.
We can safely remove the sun5i sched-clock on those systems, since we

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the GPIO interrupts earlier until I found some suitable pins
to test with. We can mux the MMC card detect and write protect pins
from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that
are also suitable for the MMC subsystem.
This turned out several issues that need to be fixed:
- I set the GPIO type wrong to be compatible with omap3 instead
of omap4. The GPIO controller on dm816x has EOI interrupt
register like omap4 and am335x.
- I got the GPIO interrupt numbers wrong as each bank has two
and we only use one. They need to be set up the same way as
on am335x.
- The gpio banks are missing interrupt controller related
properties.
With these changes the GPIO interrupts can be used with the
MMC card detect pin, so let's wire that up. Let's also mux all
the MMC lines for completeness while at it.
For the first GPIO bank I tested using GPMC lines temporarily
muxed to GPIOs on the dip switch 10.

Pull perf fix from Ingo Molnar:
"A perf kernel side fix for a fuzzer triggered lockup"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf: Fix irq_work 'tail' recursion
When non-realtime tasks get priority-inheritance boosted to a realtime
scheduling class, RLIMIT_RTTIME starts to apply to them. However, the
counter used for checking this (the same one used for SCHED_RR
timeslices) was not getting reset. This meant that tasks running with a
non-realtime scheduling class which are repeatedly boosted to a realtime
one, but never block while they are running realtime, eventually hit the
timeout without ever running for a time over the limit. This patch
resets the realtime timeslice counter when un-PI-boosting from an RT to
a non-RT scheduling class.
I have some test code with two threads and a shared PTHREAD_PRIO_INHERIT
mutex which induces priority boosting and spins while boosted that gets
killed by a SIGXCPU on non-fixed kernels but doesn't with this patch
applied. It happens much faster with a CONFIG_PREEMPT_RT kernel, and
does happen eventually with PREEMPT_VOLUNTARY kernels.

Dots aren't usually used in node names even though ePAPR permits

As the sunxi usb clocks all contain a reset controller, it is not
possible to build the sunxi clock driver without RESET_CONTROLLER
enabled. Doing so results in an undefined symbol error:
drivers/built-in.o: In function `sunxi_gates_clk_setup':
linux/drivers/clk/sunxi/clk-sunxi.c:1071: undefined reference to
`reset_controller_register'
This is possible if building a minimal kernel without PHY_SUN4I_USB.
The dependency issue is made visible at compile time instead of
link time by the new A80 mmc clocks, which also use a reset control
itself.
This patch makes ARCH_SUNXI select ARCH_HAS_RESET_CONTROLLER and
RESET_CONTROLLER.

Which is caused by an irq_work generating new irq_work and therefore
not allowing forward progress.
This happens because processing the perf irq_work triggers another
perf event (tracepoint stuff) which in turn generates an irq_work ad
infinitum.
Avoid this by raising the recursion counter in the irq_work -- which
effectively disables all software events (including tracepoints) from
actually triggering again.

The hrtimer mode of broadcast queues hrtimers in the idle entry
path so as to wakeup cpus in deep idle states. The associated
call graph is :
cpuidle_idle_call()
|____ clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER, ....))
|_____tick_broadcast_set_event()
|____clockevents_program_event()
|____bc_set_next()
The hrtimer_{start/cancel} functions call into tracing which uses RCU.
But it is not legal to call into RCU in cpuidle because it is one of the
quiescent states. Hence protect this region with RCU_NONIDLE which informs
RCU that the cpu is momentarily non-idle.
As an aside it is helpful to point out that the clock event device that is
programmed here is not a per-cpu clock device; it is a
pseudo clock device, used by the broadcast framework alone.
The per-cpu clock device programming never goes through bc_set_next().

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.
Big surprise.
But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?
In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.
Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.
But hey, I asked, so I'll honor the votes.

Module unload calls lockdep_free_key_range(), which removes entries
from the data structures. Most of the lockdep code OTOH assumes the
data structures are append only; in specific see the comments in
add_lock_to_list() and look_up_lock_class().
Clearly this has only worked by accident; make it work proper. The
actual scenario to make it go boom would involve the memory freed by
the module unlock being re-allocated and re-used for a lock inside of
a rcu-sched grace period. This is a very unlikely scenario, still
better plug the hole.
Use RCU list iteration in all places and ammend the comments.
Change lockdep_free_key_range() to issue a sync_sched() between
removal from the lists and returning -- which results in the memory
being freed. Further ensure the callers are placed correctly and
comment the requirements.

ARM: dts: rockchip: disable gmac by default in rk3288.dtsi
MAINTAINERS: add rockchip regexp to the ARM/Rockchip entry
The commit "ARM: pxa: arbitrarily set first interrupt number" changed
the first pxa interrupt to 16.
As a consequence, device-tree builds got broken, because :
- pxa_mask_irq() and pxa_unmask_irq() are using IRQ_BIT()
- IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0)
Before the commit, the first interrupt shift, PXA_IRQ(0) was 0,
therefore IRQ_BIT(x) was x. After the change, it is necessary that the
same shift of 16 is applied between the virtual interrupt number and the
hardware irq number.
This situation comes from the common irq_chip shared between legacy
platform builds and device-tree builds.
Fix the broken interrupts in DT case by adding this shift in the DT case
too.
As a consequence of the IRQ_BIT() is removed alltogether from interrupts
handling, even in the platform data types of platforms :
- a legacy irq domain is used
- the irq_chip handles hardware interrupts
- the virtual to hardware interrupt conversion is fully handled by irq
domain mechanics

Kernfs supports two styles of read: direct_read and seqfile_read.
The latter supports 'poll' correctly thanks to the update of
'->event' in kernfs_seq_show.
The former does not as '->event' is never updated on a read.
So add an appropriate update in kernfs_file_direct_read().
This was noticed because some 'md' sysfs attributes were
recently changed to use direct reads.

First are the usual driver fixes for new regressions since v3.19.
Second are fixes to the common clock divider type caused by recent

that use this common code.
Finally there are fixes for drivers that improperly compared struct
clk pointers (drivers must not deref these pointers). While some of
these drivers have done this for a long time, this did not cause a
problem until we started generating unique struct clk pointers for
every consumer. A new function, clk_is_match was introduced to get
these drivers working again and they are fixed up to no longer deref
the pointers themselves"

Commit 4f579ae7de56 (ext4: fix punch hole on files with indirect
mapping) rewrote FALLOC_FL_PUNCH_HOLE for ext4 files with indirect
mapping. However, there are bugs in several corner cases. This fixes 5
distinct bugs:
1. When there is at least one entire level of indirection between the
start and end of the punch range and the end of the punch range is the
first block of its level, we can't return early; we have to free the
intervening levels.
2. When the end is at a higher level of indirection than the start and
ext4_find_shared returns a top branch for the end, we still need to free
the rest of the shared branch it returns; we can't decrement partial2.
3. When a punch happens within one level of indirection, we need to
converge on an indirect block that contains the start and end. However,
because the branches returned from ext4_find_shared do not necessarily
start at the same level (e.g., the partial2 chain will be shallower if
the last block occurs at the beginning of an indirect group), the walk
of the two chains can end up "missing" each other and freeing a bunch of
extra blocks in the process. This mismatch can be handled by first
making sure that the chains are at the same level, then walking them
together until they converge.
4. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the start, we must free it,
but only if the end does not occur within that branch.
5. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the end, then we shouldn't
free the block referenced by the end of the returned chain (this mirrors
the different levels case).

Patch queue for 4.0 - 2015-03-25
A few bug fixes for Book3S HV KVM:
- Fix spinlock ordering
- Fix idle guests on LE hosts
- Fix instruction emulation
The patch dc6c9a35b66b520cf67e05d8ca60ebecad3b0479 that counts pmds
allocated for a process introduced a bug on 64-bit PA-RISC kernels.
The PA-RISC architecture preallocates one pmd with each pgd. This
preallocated pmd can never be freed - pmd_free does nothing when it is
called with this pmd. When the kernel attempts to free this preallocated
pmd, it decreases the count of allocated pmds. The result is that the
counter underflows and this error is reported.
This patch fixes the bug by artifically incrementing the counter in
pmd_free when the kernel tries to free the preallocated pmd.

The sun5i timer is used as the sched-clock on certain systems, and ever
since we started using cpufreq, the cpu clock (that is one of the
timer's clock indirect parent) now changes as well, along with the
actual sched_clock() rate.
This is not accurate and not desirable.
We can safely remove the sun5i sched-clock on those systems, since we
have other reliable sched_clock() sources in the system.

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the GPIO interrupts earlier until I found some suitable pins
to test with. We can mux the MMC card detect and write protect pins
from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that
are also suitable for the MMC subsystem.
This turned out several issues that need to be fixed:
- I set the GPIO type wrong to be compatible with omap3 instead
of omap4. The GPIO controller on dm816x has EOI interrupt
register like omap4 and am335x.
- I got the GPIO interrupt numbers wrong as each bank has two
and we only use one. They need to be set up the same way as
on am335x.
- The gpio banks are missing interrupt controller related
properties.
With these changes the GPIO interrupts can be used with the
MMC card detect pin, so let's wire that up. Let's also mux all
the MMC lines for completeness while at it.
For the first GPIO bank I tested using GPMC lines temporarily
muxed to GPIOs on the dip switch 10.

When non-realtime tasks get priority-inheritance boosted to a realtime
scheduling class, RLIMIT_RTTIME starts to apply to them. However, the
counter used for checking this (the same one used for SCHED_RR
timeslices) was not getting reset. This meant that tasks running with a
non-realtime scheduling class which are repeatedly boosted to a realtime
one, but never block while they are running realtime, eventually hit the
timeout without ever running for a time over the limit. This patch
resets the realtime timeslice counter when un-PI-boosting from an RT to
a non-RT scheduling class.
I have some test code with two threads and a shared PTHREAD_PRIO_INHERIT
mutex which induces priority boosting and spins while boosted that gets
killed by a SIGXCPU on non-fixed kernels but doesn't with this patch
applied. It happens much faster with a CONFIG_PREEMPT_RT kernel, and
does happen eventually with PREEMPT_VOLUNTARY kernels.

As the sunxi usb clocks all contain a reset controller, it is not
possible to build the sunxi clock driver without RESET_CONTROLLER
enabled. Doing so results in an undefined symbol error:

linux/drivers/clk/sunxi/clk-sunxi.c:1071: undefined reference to

This is possible if building a minimal kernel without PHY_SUN4I_USB.
The dependency issue is made visible at compile time instead of
link time by the new A80 mmc clocks, which also use a reset control
itself.
This patch makes ARCH_SUNXI select ARCH_HAS_RESET_CONTROLLER and

Which is caused by an irq_work generating new irq_work and therefore
not allowing forward progress.
This happens because processing the perf irq_work triggers another
perf event (tracepoint stuff) which in turn generates an irq_work ad
infinitum.
Avoid this by raising the recursion counter in the irq_work -- which
effectively disables all software events (including tracepoints) from
actually triggering again.

The hrtimer mode of broadcast queues hrtimers in the idle entry
path so as to wakeup cpus in deep idle states. The associated
call graph is :
cpuidle_idle_call()
|____ clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER, ....))
|_____tick_broadcast_set_event()
|____clockevents_program_event()
|____bc_set_next()
The hrtimer_{start/cancel} functions call into tracing which uses RCU.
But it is not legal to call into RCU in cpuidle because it is one of the
quiescent states. Hence protect this region with RCU_NONIDLE which informs
RCU that the cpu is momentarily non-idle.
As an aside it is helpful to point out that the clock event device that is
programmed here is not a per-cpu clock device; it is a
pseudo clock device, used by the broadcast framework alone.
The per-cpu clock device programming never goes through bc_set_next().

However:
md.c calls ->free() even if ->private_data is NULL, which
causes problems in some personalities.
raid0.c frees the data, but doesn't clear ->private_data,
which will become a problem when we fix md.c
So better fix both these issues at once.

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.
Big surprise.
But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?
In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.
Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.
But hey, I asked, so I'll honor the votes.

Module unload calls lockdep_free_key_range(), which removes entries
from the data structures. Most of the lockdep code OTOH assumes the
data structures are append only; in specific see the comments in
add_lock_to_list() and look_up_lock_class().
Clearly this has only worked by accident; make it work proper. The
actual scenario to make it go boom would involve the memory freed by
the module unlock being re-allocated and re-used for a lock inside of
a rcu-sched grace period. This is a very unlikely scenario, still
better plug the hole.
Use RCU list iteration in all places and ammend the comments.
Change lockdep_free_key_range() to issue a sync_sched() between
removal from the lists and returning -- which results in the memory
being freed. Further ensure the callers are placed correctly and
comment the requirements.

The commit "ARM: pxa: arbitrarily set first interrupt number" changed
the first pxa interrupt to 16.
As a consequence, device-tree builds got broken, because :
- pxa_mask_irq() and pxa_unmask_irq() are using IRQ_BIT()
- IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0)
Before the commit, the first interrupt shift, PXA_IRQ(0) was 0,
therefore IRQ_BIT(x) was x. After the change, it is necessary that the
same shift of 16 is applied between the virtual interrupt number and the
hardware irq number.
This situation comes from the common irq_chip shared between legacy
platform builds and device-tree builds.
Fix the broken interrupts in DT case by adding this shift in the DT case
too.
As a consequence of the IRQ_BIT() is removed alltogether from interrupts
handling, even in the platform data types of platforms :
- a legacy irq domain is used
- the irq_chip handles hardware interrupts
- the virtual to hardware interrupt conversion is fully handled by irq
domain mechanics

The current OMAP dmtimer probe does not check for the return
status of pm_runtime_get_sync() before initializing the timer
registers. Any timer with missing hwmod data would return a
failure here, and the access of registers without enabling the
clocks for the timer would trigger a l3_noc interrupt and a
kernel boot hang. Add proper checking so that the probe would
return a failure graciously without hanging the kernel boot.

Kernfs supports two styles of read: direct_read and seqfile_read.
The latter supports 'poll' correctly thanks to the update of
'->event' in kernfs_seq_show.
The former does not as '->event' is never updated on a read.
So add an appropriate update in kernfs_file_direct_read().
This was noticed because some 'md' sysfs attributes were
recently changed to use direct reads.

Commit 4f579ae7de56 (ext4: fix punch hole on files with indirect
mapping) rewrote FALLOC_FL_PUNCH_HOLE for ext4 files with indirect
mapping. However, there are bugs in several corner cases. This fixes 5
distinct bugs:
1. When there is at least one entire level of indirection between the
start and end of the punch range and the end of the punch range is the
first block of its level, we can't return early; we have to free the
intervening levels.
2. When the end is at a higher level of indirection than the start and
ext4_find_shared returns a top branch for the end, we still need to free
the rest of the shared branch it returns; we can't decrement partial2.
3. When a punch happens within one level of indirection, we need to
converge on an indirect block that contains the start and end. However,
because the branches returned from ext4_find_shared do not necessarily
start at the same level (e.g., the partial2 chain will be shallower if
the last block occurs at the beginning of an indirect group), the walk
of the two chains can end up "missing" each other and freeing a bunch of
extra blocks in the process. This mismatch can be handled by first
making sure that the chains are at the same level, then walking them
together until they converge.
4. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the start, we must free it,
but only if the end does not occur within that branch.
5. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the end, then we shouldn't
free the block referenced by the end of the returned chain (this mirrors
the different levels case).

The patch dc6c9a35b66b520cf67e05d8ca60ebecad3b0479 that counts pmds
allocated for a process introduced a bug on 64-bit PA-RISC kernels.
The PA-RISC architecture preallocates one pmd with each pgd. This
preallocated pmd can never be freed - pmd_free does nothing when it is
called with this pmd. When the kernel attempts to free this preallocated
pmd, it decreases the count of allocated pmds. The result is that the
counter underflows and this error is reported.
This patch fixes the bug by artifically incrementing the counter in
pmd_free when the kernel tries to free the preallocated pmd.
