Subject: [PATCH 0/5] x86/microcode: More urgent fixes
Date: Mon, 9 Jan 2017 12:41:42 +0100 [thread overview]
Message-ID: <20170109114147.5082-1-bp@alien8.de> (raw)
From: Borislav Petkov <bp@suse.de>
Hi guys,
here are fixes for three more issues with the microcode loader. First
one is culminating in adding an intel_get_microcode_revision() helper
which does the proper steps to get the current microcode revision on
an Intel CPU and should be used everywhere instead of opencoding (and
forgetting) to do a CPUID(1).
The other two are fixes for 06b8534cb728 ("x86/microcode: Rework
microcode loading") which slipped through my testing.
All this is for 4.10 only as it fixes fallout from stuff which went in
this merge window.
Please apply,
thanks.
Borislav Petkov (3):
x86/CPU: Add native CPUID variants returning a single datum
x86/microcode: Use native CPUID to tickle out microcode revision
x86/microcode/intel: Add a helper which gives the microcode revision
Junichi Nomura (2):
x86/microcode/intel: Fix allocation size of struct ucode_patch
x86/microcode/intel: Use correct buffer size for saving microcode data
