Hi.
Every arch implements its own show_mem() function. Most of them share
quite some code, some of them are completely identical.
This proposal implements a generic version of this functions and
migrates almost all architectures to use it.
I have only tested the x86_32 related part in lack of other archs.
As far as I understood the code, the generic version should work for
the architectures that used to iterate mem_map pfns, but I can not
tell for sure. Please give feedback.
Also, this series leaves ia64, arm, and sparc as is.
Tony, as far as I understand, ia64 jumps holes in the memory map with
vmemmap_find_next_valid_pfn(). Any idea if and how this could be
built into the generic show_mem() version?
Russell, I don't know if arm can be transformed. For now, it keeps
its arch-specific show_mem().
Dave, can sparc's version be simply migrated as well?
