Subject: [PATCH] locking: remove three unused Kconfig symbols

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. It is safe to remove
these.

Untested. These three symbols were added in commit
6beb000923882f6204ea2cfcd932e568e900803f ("locking: Make inlining
decision Kconfig based").
