has been removed from the -mm tree. Its filename was
x86_64-io_apic-implment-update_irq0_entry.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: x86_64 io_apic: Implment update_irq0_entry
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
To guess different irq routing strategies for irq 0 we need the ability to
update our data structures to reflect our guess.
update_irq0_entry updates the mp routing table information to reflect our
current guess as to the routing of the timer irq.
