Merge branch 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull a x86/build change from Ingo Molnar.
This makes the default stack alignment on x86-64 be just 8, allowing for
improved code generation (it can avoid some unnecessary extra alignment
logic and use just pure push/pop sequences) and smaller stack frames.
We can't generally do SSE with 16-byte alignment issues in the kernel anyway.
* 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86-64, gcc: Use -mpreferred-stack-boundary=3 if supported
