The patch titled
Subject: kernel/cpu.c: eliminate cpu_*_mask
has been removed from the -mm tree. Its filename was
kernel-cpuc-eliminate-cpu__mask.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: kernel/cpu.c: eliminate cpu_*_mask
Replace the variables cpu_possible_mask, cpu_online_mask, cpu_present_mask
and cpu_active_mask with macros expanding to expressions of the same type
and value, eliminating some indirection.
