Subject: linux-next: manual merge of the arm64 tree with Linus' tree
Date: Mon, 11 Jul 2016 10:14:06 +1000	[thread overview]
Message-ID: <20160711101406.66a5c148@canb.auug.org.au> (raw)

Hi Catalin,

Today's linux-next merge of the arm64 tree got a conflict in:

  arch/arm64/mm/fault.c

between commit:

  e19a6ee2460b ("arm64: kernel: Save and restore UAO and addr_limit on exception entry")

from Linus' tree and commit:

  541ec870ef31 ("arm64: kill ESR_LNX_EXEC")

from the arm64 tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
