Subject: linux-next: manual merge of the akpm tree with Linus' tree
Date: Mon, 4 Mar 2013 13:21:39 +1100 [thread overview]
Message-ID: <20130304132139.f9efee7b45655d9f75abf643@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 2367 bytes --]
Hi Andrew,
Today's linux-next merge of the akpm tree got a conflict in mm/shmem.c
between commit 26567cdbbf1a ("fix nommu breakage in shmem.c") from Linus'
tree and commit "shmem-fix-build-regression-fix" from the akpm tree.
I fixed it up (I used the latter version - see the full new version
below) and can carry the fix as necessary (no action is required).

Cheers,
Stephen Rothwell sfr@canb.auug.org.au
