Subject: [PATCH 0/2] Move RSDP address out of setup_header
Date: Tue, 20 Nov 2018 08:22:43 +0100	[thread overview]
Message-ID: <20181120072245.5378-1-jgross@suse.com> (raw)

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
