Akinobu Mita 54df2db36c sparc/srmmu: clear trailing edge of bitmap properly ... srmmu_nocache_bitmap is cleared by bit_map_init(). But bit_map_init() attempts to clear by memset(), so it can't clear the trailing edge of bitmap properly on big-endian architecture if the number of bits is not a multiple of BITS_PER_LONG. Actually, the number of bits in srmmu_nocache_bitmap is not always a multiple of BITS_PER_LONG. It is calculated as below: bitmap_bits = srmmu_nocache_size >> SRMMU_NOCACHE_BITMAP_SHIFT; srmmu_nocache_size is decided proportionally by the amount of system RAM and it is rounded to a multiple of PAGE_SIZE. SRMMU_NOCACHE_BITMAP_SHIFT is defined as (PAGE_SHIFT - 4). So it can only be said that bitmap_bits is a multiple of 16. This fixes the problem by using bitmap_clear() instead of memset() in bit_map_init() and this also uses BITS_TO_LONGS() to calculate correct size at bitmap allocation time.
