The series introduces an infrastructure to define platform specific
bits for page translation for PPC and PPC44x support for vmalloc
translation.
This is similar to what we have implemented for Crash-utility.
The patches are based makedumpfile-1.4.2 + PPC32 support patches
which is queued in for 1.4.3.

Could you tell me what kind of data is stored in vmalloc region in PPC ?
I want to estimate importance of your patches for makedumpfile.
I know at least the modules are loaded in the vmalloc'd region. I have
Cc'ed linux-ppc dev. We should be able to get enough info from the experts here.
Josh / Kumar / Others,
Could you please let us know your thoughts ?
Thanks

Modules, driver IO mappings, etc... I can see that being useful for
crashdumps.
Cheers,

Thank you for your information.
The above data may be required for one function of makedumpfile (filter
out kernel data) but not so crucial for makedumpfile as page descriptors
and related data(e.g. pglist_data).
Moreover, I'm preparing the release of v1.4.3 now, so I'll merge vmalloc
support for PPC32 into v1.4.4. Is it all right for you, Suzuki ?
Yep, fine with me.
Thanks
Suzuki
