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

Hi all,

Today's linux-next merge of the percpu tree got a conflict in mm/percpu.c
between commit 04a13c7c632e1fe04a5f6e6c83565d2559e37598 ("percpu: don't
assume existence of cpu0") from Linus' tree and commit pcpu_chunk_page_occupied ("percpu: drop pcpu_chunk->page[]") from the percpu tree.

I *think* the changes in the percpu tree supercede those in Linus' tree,
so I have used those.

Yes, the changes in Linus's tree are backported from devel branch but
the devel already has moved on and dropped one of the changes.  I'll
merge Linus's tree into percpu devel branch.

Thanks.

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

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the percpu tree got a conflict in mm/percpu.c
between commit 403a91b1659cb149dbddc5885f892734ae4542d8 ("percpu: allow
pcpu_alloc() to be called with IRQs off") from Linus' tree and commit
0f5e4816dbf38ce9488e611ca2296925c1e90d5e ("percpu: remove some sparse
warnings") from the percpu tree.

I fixed it up (see below) and can carry the fix as necessary.

I'll pull master into for-next in a few days so that we can do sparse
cleanup pass over the whole tree on the latest tree.

Thanks.

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

[-- Attachment #1: Type: text/plain, Size: 558 bytes --]

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
include/linux/percpu-defs.h between commit
b01e8dc34379f4ba2f454390e340a025edbaaa7e ("alpha: fix percpu build
breakage") from Linus' tree and commit
7c756e6e19e71f0327760d8955f7077118ebb2b1 ("percpu: implement optional
weak percpu definitions") from the percpu tree.

The latter seems to subsume the former changes, so I just used the percpu
tree version of this file.

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
arch/alpha/include/asm/percpu.h between commit
b01e8dc34379f4ba2f454390e340a025edbaaa7e ("alpha: fix percpu build
breakage") from Linus' tree and commit
6088464cf1ae9fb3d2ccc0ec5feb3f5b971098d8 ("alpha: kill unnecessary __used
attribute in PER_CPU_ATTRIBUTES") from the percpu tree.

The latter just removes what the former changed, so I used the percpu
tree version of this file.

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

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
arch/mn10300/kernel/vmlinux.lds.S between commit
2e8b5a09ebf1f98f02c1988a48415e89d4c25168 ("MN10300: Fix the vmlinux
ldscript") from Linus' tree and commit
405d967dc70002991f8fc35c20e0d3cbc7614f63 ("linker script: throw
away .discard section") from the percpu tree.

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