[PATCH 0/3] fs/ntfs3: Fixes for big endian systems

[Thomas Kühnel]

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.

  fs/ntfs3: fix endian conversion in ni_fname_name
  fs/ntfs3: add functions to modify LE bitmaps
  fs/ntfs3: use _le variants of bitops functions
