Subject: [PATCH 0/2] x86/entry/32: Get rid of paravirt_enabled in ESPFIX
Date: Mon, 29 Feb 2016 15:45:22 -0800 [thread overview]
Message-ID: <cover.1456789300.git.luto@kernel.org> (raw)
Hi Luis-
As promised, here are these patches.
Borislav, if you're okay with this (ab)use of the cpufeatures stuff
and if they survive review, I'd be okay with them joining your
series or going straight into tip:x86/asm.

x86/nmi/64: Giant debugging hack
x86/entry/32: Introduce and use X86_BUG_ESPFIX instead of
paravirt_enabled
