Subject: [GIT PULL] s390 patches for the 6.11 merge window
Hello Linus,
Please pull s390 changes for 6.11. There is a conflict with the mm tree
(not yet pulled as of now) which contains the KMSAN implementation for
s390. Please apply the following fix-up if possible to avoid build breakage:

s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception() (2024-07-17 14:30:30 +0200)
----------------------------------------------------------------
s390 updates for 6.11 merge window
- Remove restrictions on PAI NNPA and crypto counters, enabling
concurrent per-task and system-wide sampling and counting events
- Switch to GENERIC_CPU_DEVICES by setting up the CPU present mask in
the architecture code and letting the generic code handle CPU bring-up
- Add support for the diag204 busy indication facility to prevent
undesirable blocking during hypervisor logical CPU utilization
queries. Implement results caching
- Improve the handling of Store Data SCLP events by suppressing
unnecessary warning, preventing buffer release in I/O during failures,
and adding timeout handling for Store Data requests to address potential
firmware issues
- Provide optimized __arch_hweight*() implementations
- Remove the unnecessary CPU KOBJ_CHANGE uevents generated during topology
updates, as they are unused and also not present on other architectures
- Cleanup atomic_ops, optimize __atomic_set() for small values and
__atomic_cmpxchg_bool() for compilers supporting flag output constraint
- Couple of cleanups for KVM:
- Move and improve KVM struct definitions for DAT tables from gaccess.c
to a new header
- Pass the asce as parameter to sie64a()
- Make the crdte() and cspg() page table handling wrappers return a
boolean to indicate success, like the other existing "compare and swap"
wrappers
- Add documentation for HWCAP flags
- Switch to obtaining total RAM pages from memblock instead of
totalram_pages() during mm init, to ensure correct calculation of zero
page size, when defer_init is enabled
- Refactor lowcore access and switch to using the get_lowcore() function
instead of the S390_lowcore macro
- Cleanups for PG_arch_1 and folio handling in UV and hugetlb code
- Add missing MODULE_DESCRIPTION() macros
- Fix VM_FAULT_HWPOISON handling in do_exception()
