Subject: linux-next: manual merge of the uprobes tree with the tip tree

Hi Srikar,

Today's linux-next merge of the uprobes tree got a conflict in
arch/x86/kernel/signal.c between commit c5a373942bbc ("x32:
Signal-related system calls") from the tip tree and commit 1e1e2cddc33d
("x86/trivial: use is_ia32_compat_task") from the uprobes tree.

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

Cheers,
