Re: [Xen-devel] [PATCH] Fix one dead loop case in host S3

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Applied. It looks like Xen's XENPF_enter_acpi_sleep command only gets
invoked after the second write to the pm1a/pm1b control ports. So do we
actually need first-write handling in that hypercall? Is it going to be used
in future?
