Subject: [GIT PULL] s390 updates for 6.19 merge window
Hi Linus,
please pull s390 updates for the 6.19 merge window.
Note that there will be two merge conflicts:
- The new s390 system call table format conflicts with the introduction of the
new listns system call from the vfs namespace tree
- Removal of two memory hotplug states conflicts with the conversion of memory
hotplug states from macros to enums from the mm tree.
The merge conflict resolution can be found here:
https://lore.kernel.org/all/20251103100750.4522060e@canb.auug.org.au/
Thanks,
Heiko

watchdog: diag288_wdt: Remove KMSG_COMPONENT macro (2025-11-26 17:34:52 +0100)
----------------------------------------------------------------
s390 updates for 6.19 merge window
- Provide a new interface for dynamic configuration and deconfiguration of
hotplug memory, allowing with and without memmap_on_memory support. This
makes the way memory hotplug is handled on s390 much more similar to
other architectures
- Remove compat support. There shouldn't be any compat user space around
anymore, therefore get rid of a lot of code which also doesn't need to be
tested anymore
- Add stackprotector support. GCC 16 will get new compiler options, which
allow to generate code required for kernel stackprotector support
- Merge pai_crypto and pai_ext PMU drivers into a new driver. This removes
a lot of duplicated code. The new driver is also extendable and allows
to support new PMUs
- Add driver override support for AP queues
- Rework and extend zcrypt and AP trace events to allow for tracing of
crypto requests
- Support block sizes larger than 65535 bytes for CCW tape devices
- Since the rework of the virtual kernel address space the module area and
the kernel image are within the same 4GB area. This eliminates the need
of weak per cpu variables. Get rid of ARCH_MODULE_NEEDS_WEAK_PER_CPU
- Various other small improvements and fixes
