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. Signed-off-by: Jan Beulich <jbeulich@xxxxxxxxxx> Attachment:
