New Revision: 316568
URL: https://svnweb.freebsd.org/changeset/base/316568

Log:
  Cleanup the bitmap_xxx() functions in the LinuxKPI:
  
  - Move all bitmap related functions from bitops.h to bitmap.h, similar
    to what Linux does.
  
  - Apply some minor code cleanup and simplifications to optimize the
    generated code when using static inline functions.
  
  - Implement the following list of bitmap functions which are needed by
    drm-next and ibcore:
    - bitmap_find_next_zero_area_off()
    - bitmap_find_next_zero_area()
    - bitmap_or()
    - bitmap_and()
    - bitmap_xor()
  
  - Add missing include directives to the qlnxe driver
    (davidcs@ has been notified)
