[PARISC] Compat signal fixes for 64-bit parisc

In copy_siginfo_from_user32:
Use compat_uptr_t. Use compat_ptr().

In copy_siginfo_to_user32:
Use compat_int_t. Use ptr_to_compat().

The sigevent_t structure has a 64-bit si_ptr field
that when copied to a 32-bit si_ptr will copy the wrong
word. For the compat copy use the si_int field instead.

parisc and parisc64 seem to name sections a little differently from other
targets.  parisc64 gives spurious warnings like:

WARNING: drivers/net/dummy.o - Section mismatch: reference to .init.text:dummy_setup from .data.rel.ro between '.LC1' (at offset 0x0) and '.LC6'

Given the other comments in modpost.c, it seems that the best solution is
to move rodata down to the 'match at start of name' section and add
.data.rel.ro to the 'match entire name' section.

[PATCH] kexec: Avoid migration of already disabled irqs (ia64)

This patch fixes up ia64 kexec support for HP rx2620 hardware.  It does
this by skipping migration of already disabled irqs.  This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.

The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch.  This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs.  So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().

The code has been tested on three different ia64 machines, all with good
results.  It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

See report: http://marc.theaimsgroup.com/?l=linux-kernel&m=116599593200888&w=2

flush_workqueue() is not allowed to be called in the softirq context.
However, aio_complete() called from I/O interrupt can potentially call
put_ioctx with last ref count on ioctx and triggers bug.  It is simply
incorrect to perform ioctx freeing from aio_complete.

The bug is trigger-able from a race between io_destroy() and aio_complete().
A possible scenario:

cpu0                               cpu1
io_destroy                         aio_complete
  wait_for_all_aios {                __aio_put_req
     ...                                 ctx->reqs_active--;
     if (!ctx->reqs_active)
        return;
  }
  ...
  put_ioctx(ioctx)

                                     put_ioctx(ctx);
                                        __put_ioctx
                                          bam! Bug trigger!

The real problem is that the condition check of ctx->reqs_active in
wait_for_all_aios() is incorrect that access to reqs_active is not
being properly protected by spin lock.

This patch adds that protective spin lock, and at the same time removes
all duplicate ref counting for each kiocb as reqs_active is already used
as a ref count for each active ioctx.  This also ensures that buggy call
to flush_workqueue() in softirq context is eliminated.

[SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crash

sd_probe() calls class_device_add() even before initializing the
sdkp->device variable. class_device_add() eventually results in the user mode
udev program to be called. udev program can read the the allow_restart
attribute of the newly created scsi device. This is resulting in a crash as
the show function for allow_restart (i.e sd_show_allow_restart) returns the
attribute value by reading the sdkp->device->allow_restart variable. As the
sdkp->device is not initialized before calling the user mode hotplug helper,
this results in a crash.
The patch below solves it by calling class_device_add() only after the
necessary fields in the scsi_disk structure are initialized properly.

ahci/pata_jmicron: fix JMicron quirk

For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set.  This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.

The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits.  If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.

This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.

Revert "[PATCH] fix typo in geode_configre()@cyrix.c"

This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba.

It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit).  And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.

The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so).  So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.

There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.

[PATCH] __crc_... is intended to be absolute

i386 boot/compressed/relocs checks for absolute symbols and warns about
unexpected ones.  If you build with modversions, you get ~2500 warnings
about __crc_<symbol>.  These suckers are really absolute symbols - we
do _not_ want to modify them on relocation.

They are generated by genksyms - EXPORT_... generates a weak alias, then
genksyms produces an ld script with __crc_<symbol> = <checksum> and it's
fed to ld to produce the final object file.  Their only use is to match
kernel and module at modprobe time; they _must_ be absolute.

boot/compressed/relocs has a whitelist of known absolute symbols, but
it doesn't know about __crc_... stuff.  As the result, we get shitloads
of false positives on any ld(1) version.
