Merge tag 's390-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - 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
