Subject: alpha: locks: remove unused arch_*_relax operations
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8b3ed3c002666540d9782a5219fa75c8a3fba98f;p=openwrt%2Fstaging%2Fblogic.git

alpha: locks: remove unused arch_*_relax operations

The arch_{spin,read,write}_relax macros are not used anywhere in the
kernel and are typically just aliases for cpu_relax().

This patch removes the unused definitions for Alpha.
