The steps are as follows, and should be bisectable:
1. Break out all the functions into a new asm/ptemap.h and
include it in place of the original functions.
2. Move linux/mm.h arch-independent pte mapping code to
linux/ptemap.h, include asm/ptemap.h there
3. Include linux/ptemap.h directly at all use sites
(only 39 of these kernel-wide)
4. Standardize all the implementations to use
pte_offset_kernel() as the basis for pte_offset_map()
whenever possible.
5. Create asm-generic/ptemap.h and consolidate all the
architectures that share the pte_offset_kernel()
implementations.
6. Consolidate the three HIGHPTE implementations (x86,
frv, ppc64) in asm-generic/ptemap.h.
7. Remove the direct asm/ptemap.h includes.
This is a nice cleanup. Did you consider going an extra step and
converting all the macros into #defines?
