Got a naive question I cannot find the answer for: 

I have a user space page (I know the 'struct page *' and I did a
get_page() on it so it doesn't go away to swap) and I need to be able to
access it with normal pointers (to do a bunch of atomic operations on
it). I cannot use get_user() and friends, just pointers.

So, the question is, how can I map it into the kernel space in a portable
manner? Am I missing anything very basic here?

Thanks in advance :)

PS: I suspect remap_page_range() is going to be involved, but I cannot see
how.

kmap or kmap_atomic
