Hi Suzuki,
With the updated patch #2 addressing Toshi's concerns, the patch-set looks
and tests OK -- for me anyway.
One thing I will add is the translation of the PAE and CPU_BOOKE flag bits
in ppc_dump_machdep_table(), so that you'll see:
crash> help -m
platform: ppc440gp
flags: 808001 (KSYMS_START|PAE|CPU_BOOKE)
kvbase: c0000000
identity_map_base: c0000000
...
Presuming that Toshi is OK with the updated patch #2, consider the patch-set
queued for crash-6.0.4.
Thanks for all your work,
Dave
