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.)"
