[CIFS] Byte range unlock request to non-Unix server can unlock too much
On a mount without posix extensions enabled, when an unlock request is
made, the client can release more than is intended. To reproduce, on a
CIFS mount without posix extensions enabled:
1) open file
2) do fcntl lock: start=0 len=1
3) do fcntl lock: start=2 len=1
4) do fcntl unlock: start=0 len=1
...on the unlock call the client sends an unlock request to the server
for both locks. The problem is a bad test in cifs_lock.

dio: zero struct dio with kzalloc instead of manually
This patch uses kzalloc to zero all of struct dio rather than manually
trying to track which fields we rely on being zero. It passed aio+dio
stress testing and some bug regression testing on ext3.
This patch was introduced by Linus in the conversation that lead up to
Badari's minimal fix to manually zero .map_bh.b_state in commit:
6a648fa72161d1f6468dabd96c5d3c0db04f598a
It makes the code a bit smaller. Maybe a couple fewer cachelines to
load, if we're lucky:
text data bss dec hex filename
3285925 568506
1304616 5159047 4eb887 vmlinux
3285797 568506
1304616 5158919 4eb807 vmlinux.patched
I was unable to measure a stable difference in the number of cpu cycles
spent in blockdev_direct_IO() when pushing aio+dio 256K reads at
~340MB/s.
So the resulting intent of the patch isn't a performance gain but to
avoid exposing ourselves to the risk of finding another field like
.map_bh.b_state where we rely on zeroing but don't enforce it in the
code.

x86: properly initialize temp insn buffer for paravirt patching

ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code
now collects the complete new instruction stream into a temp buffer
before finally patching in the new insns. In some cases the paravirt
patchers will choose to leave the patch site unpatched (length mismatch,
clobbers mismatch, etc).
This causes the new patching code to copy an uninitialized temp buffer,
i.e. garbage, to the callsite. Simply make sure to always initialize
the buffer with the original instruction stream. A better fix is to
audit all the patchers and return proper length so that apply_paravirt()
can skip copies when we leave the patch site untouched.

fix random hang in forcedeth driver when using netconsole
If the forcedeth driver receives too much work in an interrupt, it
assumes it has a broken hardware with stuck IRQ. It works around the
problem by disabling interrupts on the nic but makes a printk while
holding device spinlog - which isn't smart thing to do if you have
netconsole on the same nic.
This patch moves the printk's out of the spinlock protected area.
Without this patch the machine hangs hard. With this patch everything
still works even when there is significant increase on CPU usage while

i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()
Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically
imply volatility for i386 and x86_64. x86_64 doesn't have this issue because
it open-codes the while loop in smpboot.c:smp_callin() itself that already
uses cpu_relax().
For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert()
which is buggy for mach-default and mach-es7000 cases.
[ I test-built a kernel -- smp_callin() itself got inlined in its only
callsite, smpboot.c:start_secondary() -- and the relevant piece of
code disassembles to the following:
0xc1019704 <start_secondary+12>: mov 0xc144c4c8,%eax
0xc1019709 <start_secondary+17>: test %eax,%eax
0xc101970b <start_secondary+19>: je 0xc1019709 <start_secondary+17>
init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and
then we loop over the test of the stale value in the register only,
so these look like real bugs to me. With the fix below, this becomes:
0xc1019706 <start_secondary+14>: pause
0xc1019708 <start_secondary+16>: cmpl $0x0,0xc144c4c8
0xc101970f <start_secondary+23>: je 0xc1019706 <start_secondary+14>

[MATH-EMU]: Fix underflow exception reporting.
The underflow exception cases were wrong.
This is one weird area of ieee1754 handling in that the underflow
behavior changes based upon whether underflow is enabled in the trap
enable mask of the FPU control register. As a specific case the Sparc
V9 manual gives us the following description:
--------------------
If UFM = 0: Underflow occurs if a nonzero result is tiny and a
loss of accuracy occurs. Tininess may be detected
before or after rounding. Loss of accuracy may be
either a denormalization loss or an inexact result.
If UFM = 1: Underflow occurs if a nonzero result is tiny.
Tininess may be detected before or after rounding.
--------------------
What this amounts to in the packing case is if we go subnormal,
we set underflow if any of the following are true:
1) rounding sets inexact
2) we ended up rounding back up to normal (this is the case where
we set the exponent to 1 and set the fraction to zero), this
should set inexact too
3) underflow is set in FPU control register trap-enable mask
The initially discovered example was "DBL_MIN / 16.0" which
incorrectly generated an underflow. It should not, unless underflow
is set in the trap-enable mask of the FPU csr.
Another example, "0x0.0000000000001p-1022 / 16.0", should signal both
inexact and underflow. The cpu implementations and ieee1754
literature is very clear about this. This is case #2 above.
However, if underflow is set in the trap enable mask, only underflow
should be set and reported as a trap. That is handled properly by the
prioritization logic in
arch/sparc{,64}/math-emu/math.c:record_exception().
Based upon a report and test case from Jakub Jelinek.

[IA64] Fix processor_get_freq
The core cpufreq code doesn't appear to understand returning -EAGAIN
for the get() function of the cpufreq_driver. If PAL_GET_PSTATE returns
-1, such as when running on Xen, scaling_cur_freq is happy to return
4294967285 kHz (ie. (unsigned)-11). The other drivers appear to return
0 for a failure, and doing so gives me the max frequency from
scaling_cur_frequency and "<unknown>" from cpuinfo_cur_frequency. I
believe that's the desired behavior.

[AVR32] Define mmiowb()
Add empty definition of mmiowb() since some drivers need it. Uncached
writes are strongly ordered on AVR32. They may be delayed if the
dcache is busy doing a writeback, but AFAICT that's not what this
macro is supposed to deal with, at least on UP systems.
We might have to revisit this definition when a SMP-capable AVR32 CPU
comes along, depending on how the busses and cache coherency stuff
end up being implemented.

- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
PCI clock -- make it properly report both clocks and add the same ability to
the 'pata_hpt3x2n' driver;
- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
