Subject: x86: stackprotector.h misc update
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=76397f72fb9f4c9a96dfe05462887811c81b0e17;p=linux-2.6-omap-h63xx.git

x86: stackprotector.h misc update

Impact: misc udpate

* wrap content with CONFIG_CC_STACK_PROTECTOR so that other arch files
  can include it directly

* add missing includes

This will help future changes.
