e1000: Fix suspend/resume powerup and irq allocation
From: Auke Kok <auke-jan.h.kok@intel.com>
After 7.0.33/2.6.16, e1000 suspend/resume left the user with an enabled
device showing garbled statistics and undetermined irq allocation state,
where `ifconfig eth0 down` would display `trying to free already freed irq`.

show_mem() was not correctly handling holes in the memory
map. It was treating the freed sections of the map as
though they contained valid struct page entries. This
could cause incorrect debugging output or even a kernel
panic.
This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory. show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function. This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver.
In this case, the card driver should get the stub version. This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well. This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

This is a rework of the ixp4xx irq_chip implementation. The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework. The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().
This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
s390. DCSS needs initialized struct pages to work. With the usage of
add_active_range() only the struct pages for physically present pages
are initialized.
This could be fixed if the DCSS driver would initiliaze the struct pages
itself, but this doesn't work too. This is because the mem_map array
does not include holes after the last present memory area and therefore
there is nothing that could be initialized.
To fix this and to avoid some dirty hacks revert this patch for now.
Will be added later when we move to a virtual mem_map.

The bcm43xx driver uses 4 locations in the devices sprom to determine
the behavior of the leds. Certain defaults are assigned if all bits are
set in those locations. On at least one BCM4303 chip, the sprom contains
values other than the default, which executes an assertion placed in the
default case of a following switch statement. This patch makes the leds

the number of logged messages to 20 for the case of unexpected values in

The IR chip has no address decoding, so the IR data is always present in
the high byte when doing a read from the saa7146 chip. This means that
the DEBI address used is irrelevant to the IR decoding logic.
DEBI addresses 0x1XXX are mapped to the registers on the CI module
itself, but only the lowest two bits are actually used (see EN50221,
section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps
to register 0 (the data register). A read from the data register is
supposed to be preceded by a read from the size register, so some CI
modules will be confused (the AlphaCrypt CAM will hang completely).
The attached patch changes the address used when reading the IR data to
use 0x4000 instead. This is the CI version address, which is a safer
default, works with the AlphaCrypt CAM and matches the behaviour of the
Windows driver (AFAIK).

Since it is becoming clear that there are just enough users of the binary
sysctl interface that completely removing the binary interface from the kernel
will not be an option for foreseeable future, we need to find a way to address
the sysctl maintenance issues.
The basic problem is that sysctl requires one central authority to allocate
sysctl numbers, or else conflicts and ABI breakage occur. The proc interface
to sysctl does not have that problem, as names are not densely allocated.
By not terminating a sysctl table until I have neither a ctl_name nor a
procname, it becomes simple to add sysctl entries that don't show up in the
binary sysctl interface. Which allows people to avoid allocating a binary
sysctl value when not needed.
I have audited the kernel code and in my reading I have not found a single
sysctl table that wasn't terminated by a completely zero filled entry. So
this change in behavior should not affect anything.
I think this mechanism eases the pain enough that combined with a little
disciple we can solve the reoccurring sysctl ABI breakage.

This fixes a netdev watchdog timeout problem.
The software needs to call netif_tx_disable before running the
hardware calibration code. The problem condition can be shown by the
following timegraph.
|---5secs - ~10 jiffies time---|---|OOPS
^ ^
last real TX periodic work stops netif
At OOPS, the following happens:
The watchdog timer triggers, because the timeout of 5secs
is over. The watchdog first checks for stopped TX.
_Usually_ TX is only stopped from the TX handler to indicate
a full TX queue. But this is different. We need to stop TX here,
regardless of the TX queue state. So the watchdog recognizes
the stopped device and assumes it is stopped due to full
TX queues (Which is a _wrong_ assumption in this case). It then
tests how far the last TX has been in the past. If it's more than
5secs (which is the case for low or no traffic), it will fire
a TX timeout.

When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function. This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver.
In this case, the card driver should get the stub version. This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well. This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

This is a rework of the ixp4xx irq_chip implementation. The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework. The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().
This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
s390. DCSS needs initialized struct pages to work. With the usage of
add_active_range() only the struct pages for physically present pages
are initialized.
This could be fixed if the DCSS driver would initiliaze the struct pages
itself, but this doesn't work too. This is because the mem_map array
does not include holes after the last present memory area and therefore
there is nothing that could be initialized.
To fix this and to avoid some dirty hacks revert this patch for now.
Will be added later when we move to a virtual mem_map.

The bcm43xx driver uses 4 locations in the devices sprom to determine
the behavior of the leds. Certain defaults are assigned if all bits are
set in those locations. On at least one BCM4303 chip, the sprom contains
values other than the default, which executes an assertion placed in the
default case of a following switch statement. This patch makes the leds
on the above mentioned interface behave correctly. In addition, it limits
the number of logged messages to 20 for the case of unexpected values in
the sprom locations.

board_early_init() is left over from some early prototyping work
where we had to initialize the SDRAM controller ourselves. This
depends on the kernel being loaded into static RAM, which just
isn't possible on any commercially available products today.
In order to run without a boot loader, we need to create a zImage
stub or have the debugger initialize the SDRAM for us (for really
low-level debugging)

The IR chip has no address decoding, so the IR data is always present in
the high byte when doing a read from the saa7146 chip. This means that
the DEBI address used is irrelevant to the IR decoding logic.
DEBI addresses 0x1XXX are mapped to the registers on the CI module
itself, but only the lowest two bits are actually used (see EN50221,
section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps
to register 0 (the data register). A read from the data register is
supposed to be preceded by a read from the size register, so some CI
modules will be confused (the AlphaCrypt CAM will hang completely).
The attached patch changes the address used when reading the IR data to
use 0x4000 instead. This is the CI version address, which is a safer
default, works with the AlphaCrypt CAM and matches the behaviour of the
Windows driver (AFAIK).

Since it is becoming clear that there are just enough users of the binary
sysctl interface that completely removing the binary interface from the kernel
will not be an option for foreseeable future, we need to find a way to address
the sysctl maintenance issues.
The basic problem is that sysctl requires one central authority to allocate
sysctl numbers, or else conflicts and ABI breakage occur. The proc interface
to sysctl does not have that problem, as names are not densely allocated.
By not terminating a sysctl table until I have neither a ctl_name nor a
procname, it becomes simple to add sysctl entries that don't show up in the
binary sysctl interface. Which allows people to avoid allocating a binary
sysctl value when not needed.
I have audited the kernel code and in my reading I have not found a single
sysctl table that wasn't terminated by a completely zero filled entry. So
this change in behavior should not affect anything.
I think this mechanism eases the pain enough that combined with a little
disciple we can solve the reoccurring sysctl ABI breakage.

This fixes a netdev watchdog timeout problem.
The software needs to call netif_tx_disable before running the
hardware calibration code. The problem condition can be shown by the
following timegraph.
|---5secs - ~10 jiffies time---|---|OOPS
^ ^
last real TX periodic work stops netif
At OOPS, the following happens:
The watchdog timer triggers, because the timeout of 5secs
is over. The watchdog first checks for stopped TX.
_Usually_ TX is only stopped from the TX handler to indicate
a full TX queue. But this is different. We need to stop TX here,
regardless of the TX queue state. So the watchdog recognizes
the stopped device and assumes it is stopped due to full
TX queues (Which is a _wrong_ assumption in this case). It then
tests how far the last TX has been in the past. If it's more than
5secs (which is the case for low or no traffic), it will fire
a TX timeout.

because NR_SYSCALLS lives in entry.S where the system call limit

make this mistake much more difficult to make.
And wire up sys_migrate_pages since the powerpc folks implemented the
