locking: Make inlining decision Kconfig based 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.

locking: Fix copy/paste errors of "ARCH_INLINE_*_UNLOCK_BH" The Kconfig symbols ARCH_INLINE_READ_UNLOCK_IRQ, ARCH_INLINE_SPIN_UNLOCK_IRQ, and ARCH_INLINE_WRITE_UNLOCK_IRQ were added in v2.6.33, but have never actually been used. Ingo Molnar spotted that this is caused by three identical copy/paste erros. Eg, the Kconfig entry for INLINE_READ_UNLOCK_IRQ has an (optional) dependency on: ARCH_INLINE_READ_UNLOCK_BH were it apparently should depend on: ARCH_INLINE_READ_UNLOCK_IRQ instead. Likewise for the Kconfig entries for INLINE_SPIN_UNLOCK_IRQ and INLINE_WRITE_UNLOCK_IRQ. Fix these three errors. This never really caused any real problems as these symbols are set (or unset) in a group - but it's worth fixing it nevertheless.

locking: Fix copy/paste errors of "ARCH_INLINE_*_UNLOCK_BH" The Kconfig symbols ARCH_INLINE_READ_UNLOCK_IRQ, ARCH_INLINE_SPIN_UNLOCK_IRQ, and ARCH_INLINE_WRITE_UNLOCK_IRQ were added in v2.6.33, but have never actually been used. Ingo Molnar spotted that this is caused by three identical copy/paste erros. Eg, the Kconfig entry for INLINE_READ_UNLOCK_IRQ has an (optional) dependency on: ARCH_INLINE_READ_UNLOCK_BH were it apparently should depend on: ARCH_INLINE_READ_UNLOCK_IRQ instead. Likewise for the Kconfig entries for INLINE_SPIN_UNLOCK_IRQ and INLINE_WRITE_UNLOCK_IRQ. Fix these three errors. This never really caused any real problems as these symbols are set (or unset) in a group - but it's worth fixing it nevertheless.

locking: Fix copy/paste errors of "ARCH_INLINE_*_UNLOCK_BH" The Kconfig symbols ARCH_INLINE_READ_UNLOCK_IRQ, ARCH_INLINE_SPIN_UNLOCK_IRQ, and ARCH_INLINE_WRITE_UNLOCK_IRQ were added in v2.6.33, but have never actually been used. Ingo Molnar spotted that this is caused by three identical copy/paste erros. Eg, the Kconfig entry for INLINE_READ_UNLOCK_IRQ has an (optional) dependency on: ARCH_INLINE_READ_UNLOCK_BH were it apparently should depend on: ARCH_INLINE_READ_UNLOCK_IRQ instead. Likewise for the Kconfig entries for INLINE_SPIN_UNLOCK_IRQ and INLINE_WRITE_UNLOCK_IRQ. Fix these three errors. This never really caused any real problems as these symbols are set (or unset) in a group - but it's worth fixing it nevertheless.
