Fails to build on RISC-V RV64 with the following:

arch/riscv/kernel/smp.c: In function ‘handle_IPI’:
arch/riscv/kernel/smp.c:195:44: error: ‘cpu’ undeclared (first use in 
this function)
   195 |                         ipi_cpu_crash_stop(cpu, get_irq_regs());
       |                                            ^~~
arch/riscv/kernel/smp.c:195:44: note: each undeclared identifier is 
reported only once for each function it appears in
arch/riscv/kernel/smp.c:217:22: error: ‘old_regs’ undeclared (first use 
in this function)
   217 |         set_irq_regs(old_regs);
       |                      ^~~~~~~~

It's caused by the patch "riscv: kexec: Fixup crash_smp_send_stop 
without multi cores".

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-5.15.y&id=87cc180470e099ae8f53e5e76cb6f4c1460d6d83

That patch relies on a much older patch that was never backported to 5.15.

The patch "riscv: kexec: Fixup irq controller broken in kexec crash 
path" should also be reverted since it's part of the same series.

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-5.15.y&id=3be3dce50bdf92817d16b3495d573186b967484c
