Hi Ingo & Andrew,

The patch sched-fix-scheduling-latencies-in-mttr in recent -mm
kernels has the bad side-effect of re-enabling interrupts even if
they were disabled. This caused bugs in Software Suspend 2 which
reenabled MTRRs whilst interrupts were already disabled.

Attached is a replacement patch which uses spin_lock_irqsave instead
of spin_lock_irq.

Kind regards,

Bernard.
