Merge tag 'asm-generic-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann: "The asm-generic tree contains three separate changes for linux-5.19: - The h8300 architecture is retired after it has been effectively unmaintained for a number of years. This is the last architecture we supported that has no MMU implementation, but there are still a few architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with and without an MMU. - A series to add a generic ticket spinlock that can be shared by most architectures with a working cmpxchg or ll/sc type atomic, including the conversion of riscv, csky and openrisc. This series is also a prerequisite for the loongarch64 architecture port that will come as a separate pull request. - A cleanup of some exported uapi header files to ensure they can be included from user space without relying on other kernel headers" * tag 'asm-generic-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: h8300: remove stale bindings and symlink sparc: add asm/stat.h to UAPI compile-test coverage powerpc: add asm/stat.h to UAPI compile-test coverage mips: add asm/stat.h to UAPI compile-test coverage riscv: add linux/bpf_perf_event.h to UAPI compile-test coverage kbuild: prevent exported headers from including <stdlib.h>, <stdbool.h> agpgart.h: do not include <stdlib.h> from exported header csky: Move to generic ticket-spinlock RISC-V: Move to queued RW locks RISC-V: Move to generic spinlocks openrisc: Move to ticket-spinlock asm-generic: qrwlock: Document the spinlock fairness requirements asm-generic: qspinlock: Indicate the use of mixed-size atomics asm-generic: ticket-lock: New generic ticket-based spinlock remove the h8300 architecture
