[PATCH v1 0/2] xarray: Clean up xarray.h

[Andy Shevchenko]

Main portion of this change is to get rid of kernel.h included into
other globally available headers. This decreases a dependency hell
degree. The first patch makes it possible to avoid math.h to be included
as bitops.h is implied by bitmap.h.

Andy Shevchenko (2):
  xarray: Use BITS_PER_LONGS()
  xarray: Don't use "proxy" headers
