Merge tag 'for-linus-4.15-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
"Two minor fixes for running as Xen dom0:
- when built as 32 bit kernel on large machines the Xen LAPIC
emulation should report a rather modern LAPIC in order to support
enough APIC-Ids
- The Xen LAPIC emulation is needed for dom0 only, so build it only
for kernels supporting to run as Xen dom0"
* tag 'for-linus-4.15-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen: XEN_ACPI_PROCESSOR is Dom0-only
x86/Xen: don't report ancient LAPIC version
