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 * tag 's390-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (92 commits) watchdog: diag288_wdt: Remove KMSG_COMPONENT macro s390/entry: Use lay instead of aghik s390/vdso: Get rid of -m64 flag handling s390/vdso: Rename vdso64 to vdso s390: Rename head64.S to head.S s390/vdso: Use common STABS_DEBUG and DWARF_DEBUG macros s390: Add stackprotector support s390/modules: Simplify module_finalize() slightly s390: Remove KMSG_COMPONENT macro s390/percpu: Get rid of ARCH_MODULE_NEEDS_WEAK_PER_CPU s390/ap: Restrict driver_override versus apmask and aqmask use s390/ap: Rename mutex ap_perms_mutex to ap_attr_mutex s390/ap: Support driver_override for AP queue devices s390/ap: Use all-bits-one apmask/aqmask for vfio in_use() checks s390/debug: Update description of resize operation s390/syscalls: Switch to generic system call table generation s390/syscalls: Remove system call table pointer from thread_struct s390/uapi: Remove 31 bit support from uapi header files s390: Remove compat support tools: Remove s390 compat support ...
