Subject: [SPARC32]: Fix UP build with spinlock debugging enabled.
X-Git-Tag: v2.6.11-rc4~14^2~13
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=487f1f5e2456a593f502e3994b6bc79946a66e5f;p=history.git

[SPARC32]: Fix UP build with spinlock debugging enabled.

atomic32.c assumes that arbitrary stuff can be passed into
spin_lock() on non-SMP builds, which is true except for when
spinlock debugging is enabled.
