Merge branch 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull two x86 kernel build changes from Ingo Molnar:
 "The first change modifies how 'make oldconfig' works on cross-bitness
  situations on x86.  It was felt the new behavior of preserving the
  bitness of the .config is more logical.  This is a leftover of the
  merge.

  The second change eliminates a Perl warning.  (There's another, more
  complete fix resulting of this warning fix, which second fix in flight
  to you via the kbuild tree, which will remove the timeconst.pl script
  altogether.)"
