Subject: powerpc/kernel: Make function __giveup_fpu() static
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1cdf039bf82a39d816ca4b8161b01c0acfca3e62;p=openwrt%2Fstaging%2Fblogic.git

powerpc/kernel: Make function __giveup_fpu() static

__giveup_fpu() is never called outside process.c, so it can be static.
That also means we don't need an empty definition in switch_to.h
