The patch titled
timer TSC check suspend notifier change
has been removed from the -mm tree. Its filename is
timer-tsc-check-suspend-notifier-change.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Shaohua Li <shaohua.li@xxxxxxxxx>
At suspend time, the TSC CPUFREQ_SUSPENDCHANGE notifier change might
wrongly enable interrupt. cpufreq driver suspend/resume is in interrupt
disabled environment.
