SubjectMap memory to user, then map it back to kernel
Hi folks.

I am looking for a way to map a memory (allocated with get_free_pages())
from kernel space to user space, so that I will later be able to map it
back with get_user_pages().

I tried remap_pfn_range(), but it didn't work as it assumes the memory
being mapped is IO range (marking vma with VM_IO flag), while
get_user_pages() works on regular memory.

Any ideas?

Thanks.
Alexander Sandler.
