Linus Torvalds 4ad0a4c234 powerpc updates for 6.6
- Add HOTPLUG_SMT support (/sys/devices/system/cpu/smt) and honour the
    configured SMT state when hotplugging CPUs into the system.
 
  - Combine final TLB flush and lazy TLB mm shootdown IPIs when using the Radix
    MMU to avoid a broadcast TLBIE flush on exit.
 
  - Drop the exclusion between ptrace/perf watchpoints, and drop the now unused
    associated arch hooks.
 
  - Add support for the "nohlt" command line option to disable CPU idle.
 
  - Add support for -fpatchable-function-entry for ftrace, with GCC >= 13.1.
 
  - Rework memory block size determination, and support 256MB size on systems
    with GPUs that have hotpluggable memory.
 
  - Various other small features and fixes.
