Subject: Add and use a generic copy_oldmem_page()
Date: Fri, 10 Jul 2020 20:55:41 -0700	[thread overview]
Message-ID: <20200711035544.2832154-1-palmer@dabbelt.com> (raw)

While adding support for kexec, Nick recently copied the arm64
copy_oldmem_page() into the RISC-V port.  Since this is shared verbatim with
arm and arm64 already, I'd like to add a generic version and so we can use it
instead.  I haven't converted over the MIPS, PPC, or SH ports: while I think we
could figure out how to share a version, they're not exactly the same right
now.  S/390 and x86 are definitely meaningfully different.

Unless there are any objections I'll include the first patch along with the
RISC-V kexec support, which I'm hoping to have for 5.9.  The code, based on
5.8-rc4, is at
ssh://git@gitolite.kernel.org/pub/scm/linux/kernel/git/palmer/linux.git -b
copy_oldmem_page .
