Subject: [PATCH 0/6] x86: infrastructure to enable FSGSBASE
Date: Mon,  4 Jun 2018 12:24:23 -0700	[thread overview]
Message-ID: <1528140269-26205-1-git-send-email-chang.seok.bae@intel.com> (raw)

Given feedbacks from [1], it was asked to make first a few
patches ready as soon as possible. To make FSGSBASE facilitated,
some helper functions and refactoring work are incorporated.
Besides that, it includes Andy's fix for accurate FS/GS base read
and cleanup for the vDSO initialization.

[1] FSGSBASE patch set V2: https://lkml.org/lkml/2018/5/31/686

Andy Lutomirski (1):
  x86/fsgsbase/64: Make ptrace read FS/GS base accurately

Chang S. Bae (5):
  x86/fsgsbase/64: Introduce FS/GS base helper functions
  x86/fsgsbase/64: Use FS/GS base helpers in core dump
  x86/fsgsbase/64: Factor out load FS/GS segments from __switch_to
  x86/msr: write_rdtscp_aux() to use wrmsr_safe()
  x86/vdso: Move out the CPU number store
