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

Hi all,

Today's linux-next merge of the powerpc tree got a conflict in
arch/powerpc/kernel/entry_64.S between commits 40792104b255 ("powerpc:
don't mess with r2 in copy_thread() and friends") and 53b50f9483cc
("powerpc: take dereferencing to ret_from_kernel_thread()") from the
signal tree and commit 12660b170253 ("powerpc: Fix
MAX_STACK_TRACE_ENTRIES too low warning !") from the powerpc tree.

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