Subject: xen / ACPI / sleep: Register an acpi_suspend_lowlevel callback.
X-Git-Tag: omap-for-v3.11/fixes-for-merge-window~19^2~16^2~4
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=068e0dc7b7c1db9801e3d7f2ba5cb1d2a552a35b;p=pandora-kernel.git

xen / ACPI / sleep: Register an acpi_suspend_lowlevel callback.

We piggyback on "x86/acpi: Provide registration for acpi_suspend_lowlevel."
to register a Xen version of the callback. The callback does not
do anything special - except it omits the x86_acpi_suspend_lowlevel.

This is necessary b/c during suspend the generic code tries to write
cr3 values that clashes with what the hypervisor has set up for the guest.
