- 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) MFC after: 1 week Sponsored by: Mellanox Technologies
