2006-07-13[MIPS] Do not count pages in holes with sparsememAtsushi Nemoto
With some memory model other than FLATMEM, the single node can contains some holes so there might be many invalid pages. For example, with two 256M memory and one 256M hole, some variables (num_physpage, totalpages, nr_kernel_pages, nr_all_pages, etc.) will indicate that there are 768MB on this system. This is not desired because, for example, alloc_large_system_hash() allocates too many entries. Use free_area_init_node() with counted zholes_size[] instead of free_area_init(). For num_physpages, use number of ram pages instead of max_low_pfn. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-07-13[MIPS] Sparsemem fixesAtsushi Nemoto
1. MIPS should select SPARSEMEM_STATIC since allocating bootmem in memory_present() will corrupt bootmap area. 2. pfn_valid() for SPARSEMEM is defined in linux/mmzone.h Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-07-10[PATCH] tty: Remove include of screen_info.h from tty.hJon Smirl
screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.
