The patch titled
ACPI: suspend: consolidate handling of Sx states.
has been removed from the -mm tree. Its filename was
acpi-suspend-consolidate-handling-of-sx-states.patch
This patch was dropped because cpuidle got dropped from git-acpi
------------------------------------------------------
Subject: ACPI: suspend: consolidate handling of Sx states.
From: Alexey Starikovskiy <astarikovskiy@xxxxxxx>
Recent changes to sleep initialization in ACPI dropped reporting of
supported Sx states above S3. Fix that and also move S5 init into same
file as other Sx. The only functional change is adding printk() for S4 and
S5 cases.
