Hi.
This patch fixes the problem on some machines when -d is specified,
that caused the crash utility not to recognize the excluded pages.
makedumpfile creates 2 bitmaps (1st-bitmap & 2nd-bitmap) on block_size
boundary and crash required both of them to be aligned to block_size
boundary, but the old version only aligned one of them. This patch
changes the length of the bitmaps and aligns both bitmaps to
block_size boundary.
Thanks
