Subject: [PATCH v2 0/4] x86 suspend cleanups
Date: Tue, 3 Feb 2026 12:58:17 -0500 [thread overview]
Message-ID: <20260203175821.511847-1-brgerst@gmail.com> (raw)
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
