Just a bit off-topic: I wonder how many more of these open

yours up - good).
I know there's open coded walks outside the tree (I maintain one) due to
there being no suitable function available from with in it...
Oh - I meant hand calculating the addresses rather than using
the pmd_addr_end and friends... but:
I needed something like:
pte_t *va_to_ptep_map(struct mm_struct *mm, unsigned int addr)
There was code in follow_page() that did basically what I needed, but it
was all contained within that function so I had to re-implement it.
If you can break out exactly what you need, and make that inline
or otherwise available via the correct header, I'm sure it would
have a good chance of being merged.
Keep in mind that you shouldn't introduce an inefficiency to
follow_page, however if that is not possible you could simply
duplicate what you need in a seperate function in mm/memory.c and
use that - better to do it once there than a lot of times in
random places.
