[Crash-utility] [Crash-utility][PATCH v3 06/10] LoongArch64: Add 'help -m/M' command support
Add loongarch64_dump_machdep_table() implementation,
display machdep_table.
E.g. With this patch:
crash> help -m
flags: 1 (KSYMS_START)
kvbase: 8000000000000000
identity_map_base: 8000000000000000
pagesize: 16384
pageshift: 14
pagemask: ffffffffffffc000
pageoffset: 3fff
pgdir_shift: 36
ptrs_per_pgd: 2048
ptrs_per_pte: 2048
stacksize: 16384
hz: 250
memsize: 68689920000 (0xffe3d0000)
bits: 64
back_trace: loongarch64_back_trace_cmd()
processor_speed: loongarch64_processor_speed()
