[PATCH] knfsd: fix race related problem when adding items to and svcrpc auth cache
If we don't find the item we are lookng for, we allocate a new one, and
then grab the lock again and search to see if it has been added while we
did the alloc. If it had been added we need to 'cache_put' the newly
created item that we are never going to use. But as it hasn't been
initialised properly, putting it can cause an oops.
So move the ->init call earlier to that it will always be fully initilised
if we have to put it.

[PATCH] fadvise() make POSIX_FADV_NOREUSE a no-op
The POSIX_FADV_NOREUSE hint means "the application will use this range of the
file a single time". It seems to be intended that the implementation will use
this hint to perform drop-behind of that part of the file when the application
gets around to reading or writing it.
However for reasons which aren't obvious (or sane?) I mapped
POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED. ie: it does readahead.
That's daft. So for now, make POSIX_FADV_NOREUSE a no-op.
This is a non-back-compatible change. If someone was using POSIX_FADV_NOREUSE
to perform readahead, they lose. The likelihood is low.
If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to
do it fully we'll need to maintain file offset/length ranges and peform all
sorts of complex tricks, and managing the lifetime of those ranges' data
structures will be interesting..
A sensible implementation would probably ignore the file range and would
simply mark the entire file as needing some form of drop-behind treatment.

This can occur when release_console_sem() is called but the log
buffer still has contents that need to be flushed. The console drivers
are called while the console_may_schedule flag is still true. The
might_sleep() is triggered when fbcon calls console_conditional_schedule().
Fix by setting console_may_schedule to zero earlier, before the call to the
console drivers.

So the code becomes more or less:

instead of
if (lock_ptr != 0) spin_lock(lock_ptr)
Which caused the oops from above.
After adding a barrier gcc creates code without this problem:
[...] (the same)
3ee: e3 c0 b0 28 00 04 lg %r12,40(%r11)
3f4: b9 02 00 cc ltgr %r12,%r12

402: R_390_PC32DBL _spin_lock+0x2
As a general note, this code of unqueue_me seems a bit fishy. The retry logic
of unqueue_me only works if we can guarantee, that the original value of
q->lock_ptr is always a spinlock (Otherwise we overwrite kernel memory). We
know that q->lock_ptr can change. I dont know what happens with the original
spinlock, as I am not an expert with the futex code.

USB: UHCI: Don't test the Short Packet Detect bit
Apparently some UHCI controllers change the value of the Short Packet
Detect (SPD) bit in the TD status word -- presumably when they receive a
short packet. This patch (as759) changes uhci-hcd to avoid assuming
that the bit is unchanged; in fact, the driver no longer looks at SPD at
all.
This fixes the second problem reported in Bugzilla #6752.

When HZ is set to 250 (new default) or 100, the time span during which

This patch adds a new unusual_devs flag for when usb-storage needs to ignore
a device that it would otherwise claim.
We need to ignore the ZyXEL G220F as it is a virtual CDROM drive which
includes the windows driver for this USB-WLAN adapter. After the windows
driver is installed on a windows system, it converts it into a WLAN adapter
(by ejecting the virtual disc).
The virtual CDROM is of no interest to Linux users. The zd1211rw driver will
automatically perform the eject operation, we just need to ensure that
usb-storage does not claim the device.

[IA64] Do not assume output registers be reservered.
We found an issue in pal.S.
According to the software runtime SPEC,
The caller's output registers do not need to be preserved for
caller. The callee may reuse input registers for any other
purpose within the procedure.
in ia64_pal_call_phys_stacked,
input registers are copied to output registers before call
into ia64_switch_mode_phys, then used to call into PAL. This
assumes output registers are preserved in ia64_switch_mode_phys,
which may not be true.
In this particular case, ia64_switch_mode_phys alloc a null frame
, and mask off psr.i.
If an interrupt comes at this small window,
or an MCA comes inside the procedure, output registers
maybe changed,
then the pal call may got some staled input registers.
This patch moves the copies from input to output
after ia64_switch_mode_phys to follow the software
runtime convention.
It also removed some unused labels in
