Kexec-tools use mem=X@Y to pass usable memories to crash kernel, but in
commit a94e4f24ec836c8984f83959 ("MIPS: init: Drop boot_mem_map") all
BIOS passed memories are removed by early_parse_mem(). I think this is
reasonable for a normal kernel but not for a crash kernel, because a
crash kernel shou
Traditionally, MIPS's contiguous low memory can be as less as 256M, so
crashkernel=X@Y may be unable to large enough in some cases. Moreover,
for the "multi numa node + sparse memory model" case, it is attempt to
allocate section_mem_maps on every node. Thus, if the total memory of a
node is more t
Add kexec/kdump support for Loongson64 by:
1, Provide Loongson-specific kexec functions: loongson_kexec_prepare(),
loongson_kexec_shutdown() and loongson_crash_shutdown();
2, Provide Loongson-specific assembly code in kexec_smp_wait();
To start Loongson64, The boot CPU needs 3 parameters:
