[Xen-devel] [PATCH] x86: fix microcode updater

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

This patch syncs up the microcode driver with linux 2.6.17 and adds on top of 
this enhancements (yet to be submitted to
lkml) to prevent the driver from disabling interrupts for long periods of time. 
This is done by IPI-ing all remote CPUs
sequentially rather than at once so they don't all race for the same spin 
lock(s). Additionally, redundant updates on
multiple siblings of the same core are now suppressed.
