Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module. Thus rename it to efi_add_memory_map_pg() and make it static to prevent further misuse outside the module. Signed-off-by: Michael Walle <michael@walle.cc> Add missing comma in sunxi_display.c.
