Subject: linux-next: manual merge of the akpm tree with the powerpc tree

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
arch/powerpc/kernel/ptrace.c between commit b0b0aa9c7faf
("powerpc/hw_brk: Fix setting of length for exact mode breakpoints") from
the powerpc tree and commit "ptrace/powerpc: revert "hw_breakpoints: Fix
racy access to ptrace breakpoints"" from the akpm tree.

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

Cheers,
