The windfarm code, in it's current incarnation, uses request_module() to
load the various submodules it needs for a given platform so that only
the main platform control module needs to be modprobed. However, it was
missing various bits. This fixes it. In the future, we'll use some
hotplug mecanisms to try to get all of this auto-loaded on the platforms
where it matters but that isn't ready yet.

Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like

eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
eth0: found link beat
eth0: autonegotiation complete: 100baseT-FD selected
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
...

Linus Torvalds <torvalds@osdl.org> said:

"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
_before_ the mask logic, so if a edge happens _while_ the device is
masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt).

So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
because if you did that, you'd lose it forever if the IRQ comes in while
you masked it. Instead, we're supposed to leave it active, and set a flag,
and IF the IRQ comes in, we just remember it, and mask it at that point
instead, and then on unmasking, we have to replay it by sending a
self-IPI."

This trivial patch solves the problem.

actually causes more problems:

"However, the new code does not look safe in all cases. If some other
task has opened more files while dup_fd() released oldf->file_lock, the
new code will update open_files to the new larger value. But newf was
allocated with the old smaller value of open_files, therefore subsequent
accesses to newf may try to write into unallocated memory."

so revert it.

[PATCH] pata_artop: fix "& (1 >>" typo
[PATCH] hpt37x: Check the enablebits

The vgetcpu per CPU initialization previously relied on CPU hotplug
events for all CPUs to initialize the per CPU state. That only
worked only on kernels with CONFIG_HOTPLUG_CPU enabled. On the
others some CPUs didn't get their state initialized properly
and vgetcpu wouldn't work.

Change the initialization sequence to instead run in a normal
initcall (which runs after the normal CPU bootup) and initialize
all running CPUs there. Later hotplug CPUs are still handled
with an hotplug notifier.

This actually simplifies the code somewhat.

A curious thing happens, however, when ata_qc_new_init fails to get
an ata_queued_cmd:

First, ata_qc_new_init handles the failure like this:
cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1);
done(cmd);

Then, we return to ata_scsi_translate and do this:
err_mem:
cmd->result = (DID_ERROR << 16);
done(cmd);

It appears to me that first we set a status code indicating that we're
ok but the device queue is full and finish the command, but then
we blow away that status code and replace it with an error flag and
finish the command a second time! That does not seem to be desirable
behavior since we merely want the I/O to wait until a command slot
frees up, not send errors up the block layer.

In the err_mem case, we should simply exit out of ata_scsi_translate
instead.

x86_64: setup saved_max_pfn correctly

2.6.19-rc4 has broken CONFIG_CRASH_DUMP support on x86_64. It is impossible
to read out the kernel contents from /proc/vmcore because saved_max_pfn is set
to zero instead of the max_pfn value before the user map is setup.

This happens because saved_max_pfn is initialized at parse_early_param() time,
and at this time no active regions have been registered. save_max_pfn is setup
from e820_end_of_ram(), more exact find_max_pfn_with_active_regions() which
returns 0 because no regions exist.

This patch fixes this by registering before and removing after the call
to e820_end_of_ram().

MMC: Do not set unsupported bits in OCR response
MMC: Poll card status after rescanning cards

Stephen Tweedie, Herbert Xu, and myself have been struggling with a very
nasty bug in Xen. But it also pointed out a small bug in the x86_64
kernel boot setup.

The GDT limit being setup by the initial bzImage code when entering into
protected mode is way too big. The comment by the code states that the
size of the GDT is 2048, but the actual size being set up is much bigger
(32768). This happens simply because of one extra '0'.

Instead of setting up a 0x800 size, 0x8000 is set up. On bare metal this
is fine because the CPU wont load any segments unless they are
explicitly used. But unfortunately, this breaks Xen on vmx FV, since it
(for now) blindly loads all the segments into the VMCS if they are less
than the gdt limit. Since the real mode segments are around 0x3000, we are
getting junk into the VMCS and that later causes an exception.

Stephen Tweedie has written up a patch to fix the Xen side and will be
submitting that to those folks. But that doesn't excuse the GDT limit
being a magnitude too big.

Unlike mmap(), the codepath for brk() creates a vma without first checking
that it doesn't touch a region exclusively reserved for hugepages. On
powerpc, this can allow it to create a normal page vma in a hugepage

Add a test to prevent this. With this patch, brk() will simply fail if it
attempts to move the break into a hugepage reserved region.

(David:)

If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example,
because the given file offset is not hugepage aligned - then do_mmap_pgoff
will go to the unmap_and_free_vma backout path.

But at this stage the vma hasn't been marked as hugepage, and the backout path
will call unmap_region() on it. That will eventually call down to the
non-hugepage version of unmap_page_range(). On ppc64, at least, that will
cause serious problems if there are any existing hugepage pagetable entries in
the vicinity - for example if there are any other hugepage mappings under the
same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud
entries. I suspect this will also cause bad problems on ia64, though I don't
have a machine to test it on.

(Hugh:)

prepare_hugepage_range() should check file offset alignment when it checks
virtual address and length, to stop MAP_FIXED with a bad huge offset from
unmapping before it fails further down. PowerPC should apply the same
prepare_hugepage_range alignment checks as ia64 and all the others do.

Then none of the alignment checks in hugetlbfs_file_mmap are required (nor
is the check for too small a mapping); but even so, move up setting of
VM_HUGETLB and add a comment to warn of what David Gibson discovered - if
hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region
when unwinding from error will go the non-huge way, which may cause bad
behaviour on architectures (powerpc and ia64) which segregate their huge
mappings into a separate region of the address space.

When ib_cancel_mad() is called, it puts the canceled send on a list
and schedules a "flushed" callback from process context. However,
this leaves a window where a receive completion could be processed
before the send is fully flushed.

This is fine, except that ib_find_send_mad() will find the MAD and
return it to the receive processing, which results in the sender
getting both a successful receive and a "flushed" send completion for
the same request. Understandably, this confuses the sender, which is
expecting only one of these two callbacks, and leads to grief such as
a use-after-free in IPoIB.

Fix this by changing ib_find_send_mad() to return a send struct only
if the status is still successful (and not "flushed"). The search of
the send_list already had this check, so this patch just adds the same
check to the search of the wait_list.

Fix interrupt routing for via 586 bridges. pirq can be 5 which needs to be
mapped to INTD. But currently the access functions can handle only pirq
1-4. this is similar to the other via chipsets where pirq 4 and 5 are both
mapped to INTD. Fixes bugzilla #7490
