- Add sorting of mcount locations at build time - Rework uaccess functions with C exception handling to shorten inline assembly size and enable full inlining. This yields near-optimal code for small constant copies with a ~40kb kernel size increase - Add support for a configurable STRICT_MM_TYPECHECKS which allows to generate better code, but also allows to have type checking for debug builds - Optimize get_lowcore() for common callers with alternatives that nearly revert to the pre-relocated lowcore code, while also slightly reducing syscall entry and exit time - Convert MACHINE_HAS_* checks for single facility tests into cpu_has_* style macros that call test_facility(), and for features with additional conditions, add a new ALT_TYPE_FEATURE alternative to provide a static branch via alternative patching. Also, move machine feature detection to the decompressor for early patching and add debugging functionality to easily show which alternatives are patched - Add exception table support to early boot / startup code to get rid of the open coded exception handling - Use asm_inline for all inline assemblies with EX_TABLE or ALTERNATIVE to ensure correct inlining and unrolling decisions - Remove 2k page table leftovers now that s390 has been switched to always allocate 4k page tables - Split kfence pool into 4k mappings in arch_kfence_init_pool() and remove the architecture-specific kfence_split_mapping() - Use READ_ONCE_NOCHECK() in regs_get_kernel_stack_nth() to silence spurious KASAN warnings from opportunistic ftrace argument tracing - Force __atomic_add_const() variants on s390 to always return void, ensuring compile errors for improper usage - Remove s390's ioremap_wt() and pgprot_writethrough() due to mismatched semantics and lack of known users, relying on asm-generic fallbacks - Signal eventfd in vfio-ap to notify userspace when the guest AP configuration changes, including during mdev removal - Convert mdev_types from an array to a pointer in vfio-ccw and vfio-ap drivers to avoid fake flex array confusion - Cleanup trap code - Remove references to the outdated linux390@de.ibm.com address - Other various small fixes and improvements all over the code -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE3QHqV+H2a8xAv27vjYWKoQLXFBgFAmfmuPwACgkQjYWKoQLX FBgTDAgAjKmZ5OYjACRfYepTvKk9SDqa2CBlQZ+BhbAXEVIrxKnv8OkImAXoWNsM mFxiCxAHWdcD+nqTrxFsXhkNLsndijlwnj/IqZgvy6R/3yNtBlAYRPLujOmVrsQB dWB8Dl38p63Ip1JfAqyabiAOUjfhrclRcM5FX5tgciXA6N/vhY3OM6k0+k7wN4Nj Dei/rCrnYRXTrFQgtM4w8JTIrwdnXjeKvaTYCflh4Q5ISJ7TceSF7cqq8HOs5hhK o2ciaoTdx212522CIsxeN3Ls3jrn8bCOCoOeSCysc5RL84grAuFnmjSajo1LFide S/TQtHXYy78Wuei9xvHi561ogiv/ww== =Kxgc -----END PGP SIGNATURE----- Merge tag 's390-6.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Vasily Gorbik: - Add sorting of mcount locations at build time - Rework uaccess functions with C exception handling to shorten inline assembly size and enable full inlining.
