[PATCH v3 0/6] MIPS: kexec/kdump: Fix smp reboot and other issues

[Dengcheng Zhu <dzhu@wavecomp.com>]

The issues are mentioned in patches 1/4/5/6. I will update kdump
documentation for MIPS if the series gets accepted. Testing has been done
on single core i6500/Boston with IOCU, dual core i6500 without IOCU, and
dual core interAptiv without IOCU.

Changes:

v3 - v2:
* Code style changes according to `scripts/checkpatch.pl --strict`.
  Patch #6, like before, still has a warning message reminding if
  MAINTAINERS needs updating. But it does NOT involve a maintainer change.
* Add LIBFDT to CPU_LOONGSON3 for default_machine_kexec_prepare().

v2 - v1:
* Tested on MIPS32R2 platform in addition to MIPS64R6.
* Added patches #5 and #6.
* In patch #2, removed the unnecessary inclusion of asm/mipsmtregs.h

Dengcheng Zhu (6):
  MIPS: Make play_dead() work for kexec
  MIPS: kexec: Let the new kernel handle all CPUs
  MIPS: kexec: Deprecate (relocated_)kexec_smp_wait
  MIPS: kexec: Do not flush system wide caches in machine_kexec()
  MIPS: kexec: Relax memory restriction
  MIPS: kexec: Use prepare method from generic platform as default
    option
