Will Deacon 3fcbb8260a ARC: atomics: unbork atomic_fetch_##op() ... In 4.19-rc1, Eugeniy reported weird boot and IO errors on ARC HSDK | INFO: task syslogd:77 blocked for more than 10 seconds. | Not tainted 4.19.0-rc1-00007-gf213acea4e88 #40 | "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this | message. | syslogd D 0 77 76 0x00000000 | | Stack Trace: | __switch_to+0x0/0xac | __schedule+0x1b2/0x730 | io_schedule+0x5c/0xc0 | __lock_page+0x98/0xdc | find_lock_entry+0x38/0x100 | shmem_getpage_gfp.isra.3+0x82/0xbfc | shmem_fault+0x46/0x138 | handle_mm_fault+0x5bc/0x924 | do_page_fault+0x100/0x2b8 | ret_from_exception+0x0/0x8 He bisected to 84c6591103 ("locking/atomics, asm-generic/bitops/lock.h: Rewrite using atomic_fetch_*()") This commit however only unmasked the real issue introduced by commit 4aef66c8ae ("locking/atomic, arch/arc: Fix build") which missed the retry-if-scond-failed branch in atomic_fetch_##op() macros. The bisected commit started using atomic_fetch_##op() macros for building the rest of atomics.
