lm87_init_client() conditionally sets the Start bit and clears the
INT#_Clear bit in the Config 1 register. The condition should be that
either of these bits needs changing, but currently it checks the
(self-clearing) Initialization bit instead of INT#_Clear.
Fix the condition and also ensure we never set the Initialization bit.

cifs: don't use CREATE_DELETE_ON_CLOSE in cifs_rename_pending_delete
CREATE_DELETE_ON_CLOSE apparently has different semantics than when you
set the DELETE_ON_CLOSE bit after opening the file. Setting it in the
open says "delete this file as soon as this filehandle is closed". That's
not what we want for cifs_rename_pending_delete.
Don't set this bit in the CreateFlags. Experimentation shows that
setting this flag in the SET_FILE_INFO call has no effect.

x86 ACPI: Fix breakage of resume on 64-bit UP systems with SMP kernel
We are now using per CPU GDT tables in head_64.S and the original
early_gdt_descr.address is invalidated after boot by
setup_per_cpu_areas(). This breaks resume from suspend to RAM on
x86_64 UP systems using SMP kernels, because this part of head_64.S
is also executed during the resume and the invalid GDT address
causes the system to crash. It doesn't break on 'true' SMP systems,
because early_gdt_descr.address is modified every time
native_cpu_up() runs. However, during resume it should point to the
GDT of the boot CPU rather than to another CPU's GDT.
For this reason, during suspend to RAM always make
early_gdt_descr.address point to the boot CPU's GDT.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11568, which
is a regression from 2.6.26.

This reverts commit 740f370dc6.
It turned out to be correct in the first place: a positive value should
be sent when the wheel is moved to the right, and a negative value when
moved to the left. This is the behavior expected by the Xorg evdev
driver. I must have had a remapping somewhere else in my system when
originally testing this. Testing on another system shows that the
unpatched kernel is correct.

profiling. Instead of allocating only online cpus, all possible cpu

does not sync this buffer.
