In the Linux kernel, the following vulnerability has been resolved:
acpi: Fix suspend with Xen PV
Commit f1e525009493 ("x86/boot: Skip realmode init code when running as
Xen PV guest") missed one code path accessing real_mode_header, leading
to dereferencing NULL when suspending the system under Xen:
[ 348.284004] PM: suspend entry (deep)

[ 348.816093] RIP: e030:acpi_get_wakeup_address+0xc/0x20
Fix that by adding an optional acpi callback allowing to skip setting
the wakeup address, as in the Xen PV case this will be handled by the
hypervisor anyway.
