Merge tag 'asm-generic-fixes-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic fixes from Arnd Bergmann: "These are some bugfixes for system call ABI issues I found while working on a cleanup series. None of these are urgent since these bugs have gone unnoticed for many years, but I think we probably want to backport them all to stable kernels, so it makes sense to have the fixes included as early as possible. One more fix addresses a compile-time warning in kallsyms that was uncovered by a patch I did to enable additional warnings in 6.10. I had mistakenly thought that this fix was already merged through the module tree, but as Geert pointed out it was still missing" * tag 'asm-generic-fixes-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: kallsyms: rework symbol lookup return codes linux/syscalls.h: add missing __user annotations syscalls: mmap(): use unsigned offset type consistently s390: remove native mmap2() syscall hexagon: fix fadvise64_64 calling conventions csky, hexagon: fix broken sys_sync_file_range sh: rework sync_file_range ABI powerpc: restore some missing spu syscalls parisc: use generic sys_fanotify_mark implementation parisc: use correct compat recv/recvfrom syscalls sparc: fix compat recv/recvfrom syscalls sparc: fix old compat_sys_select() syscalls: fix compat_sys_io_pgetevents_time64 usage ftruncate: pass a signed offset
