Subject: linux-next: manual merge of the akpm-current tree with the powerpc tree
Date: Fri, 4 Mar 2016 18:49:50 +1100
Message-ID: <20160304184950.7aead922@canb.auug.org.au> (raw)

Hi all,

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

  mm/huge_memory.c

between commit:

  ff20c2e0acc5 ("mm: Some arch may want to use HPAGE_PMD related values as variables")

from the powerpc tree and commit:

  82fdbe051e29 ("mm: make optimistic check for swapin readahead")

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
Stephen Rothwell
