Subject: [PATCH urgent 0/3] __restore_processor_state() fixes
Date: Thu, 14 Dec 2017 13:19:04 -0800	[thread overview]
Message-ID: <cover.1513286253.git.luto@kernel.org> (raw)

__restore_processor_state() was spaghetti code, made no sense, and
had bugs.  And I broke resume on 32-bit systems.  This series cleans
it up and fixes it (hopefully!).

Andy Lutomirski (3):
  x86/power/64: Use struct desc_ptr for the IDT in struct saved_context
  x86/power/32: Move SYSENTER MSR restoration to fix_processor_context()
  x86/power: Make restore_processor_context() sane
