Hi, all!

I have a use-case when I may need to call __vmap for kernel provided IPAs (read MFNs)

which may not be PAGE_SIZE aligned etc.

The question is if it is safe to call __vmap multiple times for different IPAs

sharing the same page (mfn), e.g. map something like 6ca00 0080 and 6ca00 00a0?

Thank you,

Oleksandr
