- Add support for sclp-vt220 terminal resize events e.g. for QEMU
- Warn if kernel command line contains non-printable EBCDIC
characters
- Improve show_code() disassembly output by using reliable markers for
the instruction address and faulting instruction
- Rework exception handling to require only a single exception table
entry per faulting instruction: convert all inline assemblies from
EX_TABLE to the new EX_TABLE_INSN macros. The previous exception
handling was error prone since it usually required two EX_TABLE
entries: one pointing at the instruction, and one pointing behind it
- Disallow kprobes on instructions with exception table entries to avoid
exception handlers decoding a breakpoint instead of the original
instruction
- Preemptible percpu ops changes:
- Simplify percpu_entry() and percpu_exit() by encoding the percpu
base, offset, and pointer registers into the lowcore marker, allowing
percpu_exit() to update the percpu pointer on CPU migration without
comparing the interrupted instruction
- Convert this_cpu_cmpxchg(), this_cpu_xchg(), and
this_cpu_cmpxchg128() to preemptible percpu ops; provide
this_cpu_try_cmpxchg()
- Emulate virtual timer in appldata via delayed work and remove the
s390 specific vtimer infrastructure
- Add lock contention tracepoints to rwlock slowpath
- Fix incorrect return address in signal frame setup
- Fix cpum_cf CPU hotplug handling
- Convert various __get_free_pages() / get_zeroed_page() users to
kmalloc() / kzalloc()
- PCI:
- Improve RPCIT instruction tracing
- Fix double-free, use-after-free, and resource leaks in zPCI MSI
and IRQ setup / cleanup paths
- Crypto and zcrypt:
- Improve reply message and length verification checks for CCA,
EP11, and ICA messages to prevent out-of-bounds reads
- Add missing array_index_nospec() for domain index uses in zcrypt to
prevent speculative execution bypass
- Fix out-of-bounds read in cca_query_crypto_facility()
- Various other small fixes and improvements
