This patchset applies on top of: git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git microcode
It includes a regression fix (patch 2), an architectural requirement violation fix (patch 7), and several enhancements. Patch 7 (x86, microcode, intel: guard against misaligned microcode data) has to align and restore the microcode data for each core that needs an update. The extra time to align the microcode data was not noticeable in simple testing: it got lost in the noise of WRMSR 0x79. FWIW, iucode-tool v1.0.3+ (https://gitorious.org/iucode-tool/pages/Home) will pre-align the microcode in the early-initramfs, so that the kernel won't have to do it. Patch 7 documents two hacks to pre-align the microcode data inside the early-initramfs so that people can write their own tools to do it, if they want to.
