Subject: powerpc/security: Make symbol 'stf_barrier' static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7f262b4dcf7edf75097c3946e676d6c6d77fc599;p=linux.git

powerpc/security: Make symbol 'stf_barrier' static

The sparse tool complains as follows:

arch/powerpc/kernel/security.c:253:6: warning:
 symbol 'stf_barrier' was not declared. Should it be static?

This symbol is not used outside of security.c, so this commit marks it
static.
