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.)" * 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timeconst.pl: Eliminate Perl warning x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT
