- 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.

This module should only be used for low power (router) devices

without hardware AES acceleration (e.g. caam crypto). It reduces the

size of the AES tables from 16KB to 8KB + 256 bytes and mitigates

timining attacks. Nevertheless it might be not as secure as other

architecture specific assembler implementations that work on 1KB
