Hello, Linux, Please pull the following cmpxchg()-related changes: git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git tags/cmpxchg.2024.09.14a # HEAD: c81a748edefd098ea21dd35d4bba03f69412fc26: sh: Emulate one-byte cmpxchg (2024-09-13 07:10:38 -0700) ---------------------------------------------------------------- ARC/sh: Provide one-byte cmpxchg emulation This series provides emulated one-byte cmpxchg() support for ARM and sh using the cmpxchg_emu_u8() function that uses a four-byte cmpxchg() to emulate the one-byte variant. A similar patch for emulation of one-byte cmpxchg() for xtensa has not yet received a maintainer ack, so it is slated for the v6.13 merge window. If you are not that patient, there is another signed tag covering all three (ARC, sh, and xtensa) named cmpxchg.2024.09.15a. ---------------------------------------------------------------- Paul E.
