[PATCH] kexec: x86: i8259 shutdown: disable interrupts

Browse source

From: Eric W. Biederman <ebiederm@xmission.com>

This patch disables interrupt generation from the legacy pic on reboot.  Now
that there is a sys_device class it should not be called while drivers are
still using interrupts.

There is a report about this breaking ACPI power off on some systems.

However the final comment seems to exonerate this code.  So until
I get more information I believe that was a false positive.
