Subject: x86, fpu: check __clear_user() return value
X-Git-Tag: v2.6.28-rc1~699^2^8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9f482807a6bd7e2aa1ed0d8cfc48463ec4ca3568;p=pandora-kernel.git

x86, fpu: check __clear_user() return value

fix warning:

  arch/x86/kernel/xsave.c: In function ‘save_i387_xstate’:
  arch/x86/kernel/xsave.c:98: warning: ignoring return value of ‘__clear_user’, declared with attribute warn_unused_result

check the return value and act on it. We should not be ignoring faults
at this point.
