Subject: [PATCH 0/2] Add HARDLOCKUP_DETECTOR_PERF for riscv 

This patchset is mainly based on RISCV_SSE, and the enabling of the
hardlockup perf feature depends on RISCV_PMU_SSE.
Link: https://lore.kernel.org/all/20250808153901.2477005-1-cleger@rivosinc.com/
patch[1]: Move watchdog_hld.c to kernel/ to facilitate reuse by RISC-V.
patch[2]: Add Kconfig selections for RISC-V.

Yunhui Cui (2):
  watchdog: refactor watchdog_hld functionality
  riscv: add HARDLOCKUP_DETECTOR_PERF support
