Subject: [GIT PULL] x86 fixes
Date: Fri, 8 Jan 2016 13:57:54 +0100
Message-ID: <20160108125753.GA7221@gmail.com> (raw)

Linus,

Please pull the latest x86-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-urgent-for-linus

   # HEAD: dd7a5ab495019d424c2b0747892eb2e38a052ba5 x86/numachip: Fix NumaConnect2 MMCFG PCI access

A handful of x86 fixes:

 - a syscall ABI fix, fixing an Android breakage
 - a Xen PV guest fix relating to the RTC device, causing a non-working console
 - a Xen guest syscall stack frame fix
 - an MCE hotplug CPU crash fix

 Thanks,

	Ingo
