Subject: [RFC] change suspend_finish order slightly
Date: Fri, 02 Dec 2005 19:15:48 -0800 [thread overview]
Message-ID: <1133579748.7835.6.camel@linux.site> (raw)
[-- Attachment #1: Type: text/plain, Size: 967 bytes --]
The BIOS guys here require ACPI _WAK method which is called in
pm_ops->finish is invoked after all CPUs are resumed. Detail info can be
found at http://bugzilla.kernel.org/show_bug.cgi?id=5651. To do this,
this patch tries to change the order slightly. Does this break other
platforms?
Thanks,
Shaohua
