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

Hi all,

Today's linux-next merge of the tip tree got a conflict in:

include/linux/sched/signal.h
include/linux/tracehook.h
kernel/signal.c
kernel/task_work.c

between commits:

fdb5f027ce66 ("task_work: use TIF_NOTIFY_SIGNAL if available")
bf6996650675 ("task_work: remove legacy TWA_SIGNAL path")
ceb39b7c17b7 ("kernel: remove checking for TIF_NOTIFY_SIGNAL")

from the block tree and commit:

114518eb6430 ("task_work: Use TIF_NOTIFY_SIGNAL if available")
12db8b690010 ("entry: Add support for TIF_NOTIFY_SIGNAL")

from the tip tree.

I fixed it up (I just used the former versions - this may be wrong,
please let me know) and can carry the fix as necessary. This is now fixed
as far as linux-next is concerned, but any non trivial conflicts should
be mentioned to your upstream maintainer when your tree is submitted for
merging. You may also want to consider cooperating with the maintainer
of the conflicting tree to minimise any particularly complex conflicts.

Jens, how is that supposed to work?

You need to merge the 'core-entry-notify-signal' tag from the tip tree
into your next branch to make the follow up changes actually work.

Ideally you send the whole arch + core cleanup muck my way once the
architecture people are happy.

Thanks,

I just haven't rebased with that pulled in yet, will do that this
morning.

Crossing fingers that I'll be able to collect all of the reviews in
time, some of them have been picked up in arch trees though. So probably
the easiest if we keep the setup as it is, which should work fine as
soon as I pull in your core branch.
