ACPI: acpi_os_wait_semaphore(): silence complaint
The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out
and return True without acquiring the semaphore. There's no indication in
the spec that this is an actual error, so this message should be
debug-only, as the message for successful acquisition is.
This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as
ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas'
recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.

This reverts commit
c7b2eff059fcc2d1b7085ee3d84b79fd657a537b.
Hugh Dickins explains:
"It seems too little tested: "losetup -d /dev/loop0" fails with
EINVAL because nothing sets lo_thread; but even when you patch
loop_thread() to set lo->lo_thread = current, it can't survive
more than a few dozen iterations of the loop below (with a tmpfs
mounted on /tst):
j=0
cp /dev/zero /tst
while :
do
let j=j+1
echo "Doing pass $j"
losetup /dev/loop0 /tst/zero
mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1
mount -t ext2 /dev/loop0 /mnt
umount /mnt
losetup -d /dev/loop0
done
it collapses with failed ioctl then BUG_ON(!bio).
I think the original lo_done completion was more subtle and safe
than the kthread conversion has allowed for."

rather see it printed out the way other arches do it, i.e.

x86_64 and i386 behave inconsistently when sending an IPI on vector 2
(NMI_VECTOR). Make both behave the same, so IPI 2 is sent as NMI.
The crash code was abusing send_IPI_allbutself() by passing a code
instead of a vector, it only worked because crash knew about the
internal code of send_IPI_allbutself(). Change crash to use NMI_VECTOR
instead, and remove the comment about how crash was abusing the function.
This patch is a pre-requisite for fixing the problem where sending an
IPI as NMI would reboot some Dell Xeon systems. I cannot fix that
problem while crash continus to abuse send_IPI_allbutself().
It also removes the inconsistency between i386 and x86_64 for
NMI_VECTOR. That will simplify all the RAS code that needs to bring
