Xen devel - Jun 2008 - [patch]Fix a bug that can''t resume from S3 after create an HVM guest

Hi, Keir,

If we don''t use PIT, we should disable it at boot time and at S3
resuming. In Xen this is done by disable_pit_irq(), but this function is
used by __initcall(). After bootstrap it will be discarded and may be
overwritten. This usually results in S3 resuming failure. This patch
fixed the issue.

This new patch may be better, just remove "__init" modifier of
disable_pit_irq().
