NAME
       __bitmap_shift_left - logical left shift of the bits in a bitmap

SYNOPSIS
       void __bitmap_shift_left(unsigned long * dst,
				const unsigned long * src, int shift,
				int bits);

ARGUMENTS
       dst
	   destination bitmap

       src
	   source bitmap

       shift
	   shift by this many bits

       bits
	   bitmap size, in bits

DESCRIPTION
       Shifting left (multiplying) means moving bits in the LS -> MS
       direction. Zeros are fed into the vacated LS bit positions and those MS
       bits shifted off the top are lost.
