Subject: linux-next: manual merge of the galak tree with Linus' tree

Hi Kumar,

Today's linux-next merge of the galak tree got a conflict in
arch/powerpc/sysdev/fsl_msi.c between commit
61c7a080a5a061c976988fd4b844dfb468dda255 ("of: Always use 'struct
device.of_node' to get device node pointer") from Linus' tree and commits
061ca4adfb2e3c986a182fd30f7e939a1ff8d29d ("powerpc/fsl_msi: enable msi
sharing through AMP OSes") and 480599933a69a8a8dc1390c2164e49e20a1593b9
("powerpc/fsl_msi: add removal path and probe failing path") from the
galak tree.

I fixed it up (see below) and can carry the fix for a while.
