Merge tag 'riscv-for-linus-6.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:

 - PERF_TYPE_BREAKPOINT now returns -EOPNOTSUPP instead of -ENOENT,
   which aligns to other ports and is a saner value

 - The KASAN-related stack size increasing logic has been moved to a C
   header, to avoid dependency issues

  riscv: Fix kernel stack size when KASAN is enabled
