The patch titled
i386: prepare sharing the PIT code
has been removed from the -mm tree. Its filename was
x86_64-use-i386-i8253-h.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: i386: prepare sharing the PIT code
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
PIT clock events work already and the PIT handling is the same for i386 and
x86_64. x86_64 does not support PIT as a clock source, so disable the PIT
clocksource for x86_64.
Use the i386 i8253.h include file for x86_64 as well to share the
exports and the PIT constants.
