The patch titled
genapic: remove ES7000 workaround
has been removed from the -mm tree. Its filename was
genapic-remove-es7000-workaround.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: genapic: remove ES7000 workaround
From: Ingo Molnar <mingo@xxxxxxx>
Remove ES7000 workaround. Although not spelled out clearly, it is likely that
the real bug was that clustered APIC mode does not work on those systems. So
if the CPU count is low then these systems can use logical delivery mode just
as much. The quirk forced physical APIC mode under all circumstances.
(patch needs testing on at least one of those systems with a CPU
count of 8 or lower.)
