Linus,

please pull the latest sched/rt branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-rt-2024-09-17

up to:  2638e4e6b182: riscv: Allow to enable PREEMPT_RT.

Enable PREEMPT_RT on supported architectures:

  After twenty years of development we finally reached the point to enable
  PREEMPT_RT support in the mainline kernel.

  All prerequisites are merged, so enable it on the supported architectures
  ARM64, RISCV and X86(32/64-bit).

Thanks,

	tglx
