Hello Linus,
please pull s390 fixes and features for 5.3.
This is my first pull request. My PGP key id is 716A93D7,
key fingerprint: F397 316C 210A 9C03 1205 6691 467C 8ED2 716A 93D7
Please also note the fixup required to avoid s390 build error after you
pull Greg's driver-core changes for 5.3:
http://lkml.kernel.org/r/[email protected]
I'm also including the corresponding patch as a follow up email for your
convenience. So you could either apply the patch after the second tree
was merged or you could simply fixup the code during merging.
Thank you,
Vasily

docs: s390: s390dbf: typos and formatting, update crash command (2019-07-05 13:42:24 +0200)
----------------------------------------------------------------
s390 updates for the 5.3 merge window
- Improve stop_machine wait logic: replace cpu_relax_yield call in generic
stop_machine function with a weak stop_machine_yield function. This is
overridden on s390, which yields the current cpu to the neighbouring cpu
after a couple of retries, instead of blindly giving up the cpu to the
hipervisor. This significantly improves stop_machine performance on s390 in
overcommitted scenarios.
This includes common code changes which have been Acked by Peter Zijlstra
and Thomas Gleixner.
- Improve jump label transformation speed: transform jump labels without
using stop_machine.
- Refactoring of the vfio-ccw cp handling, simplifying the code and
avoiding unneeded allocating/copying.
- Various vfio-ccw fixes (ccw translation, state machine).
- Add support for vfio-ap queue interrupt control in the guest.
This includes s390 kvm changes which have been Acked by Christian
Borntraeger.
- Add protected virtualization support for virtio-ccw.
- Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to remove some
code which most likely isn't working at all, besides that s390 didn't even
compile for !CONFIG_SMP.
- Support for special flagged EP11 CPRBs for zcrypt.
- Handle PCI devices with no support for new MIO instructions.
- Avoid KASAN false positives in reworked stack unwinder.
- Couple of fixes for the QDIO layer.
- Convert s390 specific documentation to ReST format.
- Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if hardware is
missing. This way our modules behave like most other modules and which is
also what systemd's systemd-modules-load.service expects.
- Replace defconfig with performance_defconfig, so there is one config file
less to maintain.
- Remove the SCLP call home device driver, which was never useful.
- Cleanups all over the place.

Thanks for the heads-up, everything looks fine and I see you have the
proper signatures on that key.

Ok, so I don't have Greg's pull request in my in-box yet, which means
that I may well forget about this by the time I do get it, and I won't
see the build failure because I don't do a s390 cross-build.
I'll _try_ to remember, but apologies in advance if this slips
through. I have the working memory of a slightly retarded chipmunk.
Greg - if you happen to remember and add a reminder to the pull
request when it gets done that would be good, but worst case the s390
people get to call me names.
