Subject: Mapping non-page aligned data to user

Hi, 

Is there a way to map a non-page aligned kernel physical address to user virtual address? remap_pfn_range and vm_insert_page operate only on page-aligned physical addresses.

If there is no such support, would it be too complicated to try out
writing something on my own to map non-page aligned addresses (the data
size is under my control - so I can make that a multiple of page size)?

Any suggestions appreciated.

Thanks
