2009-09-22arches: drop superfluous casts in nr_free_pages() callersGeert Uytterhoeven1-1/+1
Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()") modified nr_free_pages() to return 'unsigned long' instead of 'unsigned int'. This made the casts to 'unsigned long' in most callers superfluous, so remove them.

2009-08-18microblaze: Use klimit instead of _end for memory initMichal Simek1-3/+3
For noMMU system when you use larger rootfs image there is problem with using _end label because we increase klimit but in memory initialization we use still _end which is wrong. Larger mtd rootfs was rewritten by init_bootmem_node. MMU kernel use static initialization where klimit is setup to _end. There is no any other hanling with klimit.

2009-05-21microblaze: Fix paging init-zone initializationSteve Magnani1-4/+3
This patch fix problem with bad zone initialization. This bug wasn't perform because Microblaze doesn't define CONFIG_ZONE_DMA and ZONE_NORMAL was 0 for this case that's why free_area_init works with correct values. Original message: I believe that the switch from ZONE_DMA (== 0) to ZONE_NORMAL broke the free area initialization. Signed-off-by: Steven J.
