This is particularly beneficial for servers with Aspeed BMC video,
because it introduces framebuffer console acceleration. The
framebuffer console is much more responsive.
Patches were ported from 5.10.5:
0001-fake-acpi.patch: This may not be needed any more, but it applies
cleanly and I don't think it would harm anything.
0002-nmi-squelch.patch: The comment mentions qemu but I see this
message on physical machines occasionally, so I think this is needed.
0003-fake-trampoline.patch: This patch does not apply cleanly. It
could be ported, but I don't think it's needed, I dropped it. Dates
back to a very old commit where Linux was being embedded into a vendor
UEFI firmware: a4d7654b1e.
0010-winterfell-ahci.patch: Minor change of %x to %lx in context.
