[PATCH v5 0/5] MIPS: kexec/kdump: Fix smp reboot and other issues

[Dengcheng Zhu <dzhu@wavecomp.com>]

Hi Paul,

This is a rewrite of the series. Basically patches 1~3 address what we
dissussed so far. Now it allows both methods - shutting off the nonboot
CPUs and jumping to relocated_kexec_smp_wait on nonboot CPUs.

Caches are flushed before signaling reboot. CPUs are marked offline to
prevent getting IPIs. Note that this is done prior to disabling local IRQ.

Patch #4 is unchnaged. Patch #5 is the previous #6 -- I'm still putting
it in here with reasons mentioned in our discussion and in the patch
description.


Thanks,

Dengcheng Zhu (5):
  MIPS: kexec: Mark CPU offline before disabling local IRQ
  MIPS: kexec: Make a framework for both jumping and halting on nonboot
    CPUs
  MIPS: kexec: CPS systems to halt nonboot CPUs
  MIPS: kexec: Relax memory restriction
  MIPS: kexec: Use prepare method from Generic for UHI platforms
