ARM64 HugePages for linux-next

ARM64 HugePages for linux-next

[Steve Capper]

Hello,
I've been working on a patch set to add huge page support to ARM64, this
includes some changes to mm and x86. I've been advised by Andrew Morton to get
these into linux-next asap:
http://marc.info/?l=linux-mm&m=137115843813005&w=2

Would it please be possible to have the patches from the git repo below pulled
directly into linux-next?

(I've just merged them against linux-next/master and they build and run fine
for me in an ARM64 Fast Model).

Thanks,
--

Thanks for testing that.

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgment of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
	Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

Legal Stuff:
By participating in linux-next, your subsystem tree contributions are
public and will be included in the linux-next trees.  You may be sent
e-mail messages indicating errors or other issues when the
patches/commits from your subsystem tree are merged and tested in
linux-next.  These messages may also be cross-posted to the linux-next
mailing list, the linux-kernel mailing list, etc.  The linux-next tree
project and IBM (my employer) make no warranties regarding the linux-next
project, the testing procedures, the results, the e-mails, etc.  If you
don't agree to these ground rules, let me know and I'll remove your tree
from participation in linux-next.
