Subject: [PATCH v2 0/4] x86 suspend cleanups

This patchset cleans up the do_suspend_lowlevel() function, removing
some leftover bits that are no longer necessary since it started
using the SMP trampoline to resune the kernel.

v2:
- Reworked the first patch
- Added more cleanups

Brian Gerst (4):
  x86/acpi/suspend: Remove indirect jump
  x86/acpi/suspend: Remove segment reloads on resume
  x86/acpi/suspend: Clean up stack usage
  x86/acpi/suspend: Remove redundant register saves
