I tried running the NTFS3 driver on a MIPS big endian system and noticed various errors when it tried to access bitmaps structures that are stored as little endian on disk. These patches were mainly tested in a qemu mips environment. I'm open for suggestions how to better implement the second patch "add functions to modify LE bitmaps". It adds copies of two functions from lib/bitmap.c but modified to work with little endian bitmaps. Other filesystems seem to have similar functions defined locally like le_bitmap_set in btrfs or ext4_set_bits in ext4 but no global implementation exists.
