2009-12-03	mutex: Better control mutex adaptive spinning config	Frederic Weisbecker
	Introduce CONFIG_MUTEX_SPIN_ON_OWNER so that we can centralize in a single place the conditions that determine its definition and use.

2009-11-13	locking: Make inlining decision Kconfig based	Thomas Gleixner
	commit 892a7c67 (locking: Allow arch-inlined spinlocks) implements the selection of which lock functions are inlined based on defines in arch/.../spinlock.h: #define __always_inline__LOCK_FUNCTION Despite of the name __always_inline__* the lock functions can be built out of line depending on config options. Also if the arch does not set some inline defines the generic code might set them; again depending on config options. This makes it unnecessary hard to figure out when and which lock functions are inlined. Aside of that it makes it way harder and messier for -rt to manipulate the lock functions. Convert the inlining decision to CONFIG switches. Each lock function is inlined depending on CONFIG_INLINE_. The configs implement the existing dependencies. The architecture code can select ARCH_INLINE_ to signal that it wants the corresponding lock function inlined. ARCH_INLINE_* is necessary as Kconfig ignores "depends on" restrictions when a config element is selected. No functional change.
