Map 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.
