Subject: [patch 0/2] Refactor spinlock inlining

While moving preempt-rt to 2.6.32-rc I tripped over the spinlock
inlining changes and had a hard time to figure out when and which lock
function is inlined as the __always_inline__ defines are not directly
controlling the inlining because there are overrides depending on
various config options.

Merging the -rt modifications into this results in a horrible mess and
I tried to find a solution which simplifies the inlining decisions and
makes it more obvious when the decision is taken. 

To allow easier intergration of preempt-rt I reworked the inline
decision ifdeffery to be completely Kconfig based.

The result is slightly smaller in code lines, but adds a Kconfig file
which contains all the rules of inlining decisions. Architecturs can
select each locking function for inlining in the arch Kconfig instead
of defining __always_inline__*.

Thanks,

	tglx
