Subject: [PATCH] Fix compilation of processor_idle.c on IA64
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0b5c59a1e41636afa77b90d34e8c394d8d929733;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] Fix compilation of processor_idle.c on IA64

Broken earlier by me by a x86-64 patch.

The code was optimized away, but the compiler still complained about an
undeclared function.
