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: 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 arch/mips/cavium-octeon/setup.c | 2 +- arch/mips/cavium-octeon/smp.c | 35 ++++++++------- arch/mips/generic/Makefile | 1 - arch/mips/generic/kexec.c | 44 ------------------ arch/mips/include/asm/kexec.h | 9 ++-- arch/mips/include/asm/smp.h | 4 +- arch/mips/kernel/crash.c | 4 +- arch/mips/kernel/machine_kexec.c | 77 ++++++++++++++++++++++++++----- arch/mips/kernel/process.c | 2 +- arch/mips/kernel/relocate_kernel.S | 39 ---------------- arch/mips/kernel/smp-bmips.c | 11 +++-- arch/mips/kernel/smp-cps.c | 59 ++++++++++++++---------- arch/mips/loongson64/loongson-3/smp.c | 85 ++++++++++++++++++----------------- 13 files changed, 186 insertions(+), 186 deletions(-) delete mode 100644 arch/mips/generic/kexec.c -- 2.7.4
