[PATCH 0/2] Move RSDP address out of setup_header

From: Juergen Gross
Date: Tue Nov 20 2018 - 02:23:08 EST


Instead of passing the RSDP address for Xen PVH guests from grub2 to
the kernel in setup_header move it into the non-legacy part of the
boot_params structure.

This patch series should be applied rather sooner than later in order
to avoid shipping linux 4.20 with a corky boot protocol.

Juergen Gross (2):
x86/boot: revert commit ae7e1238e68f2a (Add ACPI RSDP address to
setup_header)
x86/acpi, x86/boot: Take RSDP address from boot params if available
