Subject: x86: Use "do { } while(0)" for empty flush_tlb_fix_spurious_fault() macro
X-Git-Tag: v3.3-rc1~187^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ac13462b6d242684996e88a07fbed6dec6af622;p=pandora-kernel.git

x86: Use "do { } while(0)" for empty flush_tlb_fix_spurious_fault() macro

If one builds the kernel with -Wempty-body one gets this
warning:

  mm/memory.c:3432:46: warning: suggest braces around empty body in an ¡if¢ statement [-Wempty-body]

due to the fact that 'flush_tlb_fix_spurious_fault' is a macro
that can sometimes be defined to nothing.
