From: Martin Hicks <mort@wildopensource.com> Here is a patch that changes mmu_gathers into a per-cpu resource. It includes the changes for all arches except ia64. I've sent a separate patch to David Mosberger for ia64.

In the next patch I wish to add to mm.h prototypes of functions which take an mmu_gather_t* argument. To do this I must either: a) include tlb.h in mm.h Not good - more nested includes when a simple forward decl is sufficient. b) Add `typedef struct free_pte_ctx mmu_gather_t;' to mm.h. That's silly - it's supposed to be an opaque type. or c) Remove the pesky typedef. Bingo.

I've had ia32-discontigmem under test for a month, uneventfully. Possibly because I don't have a machine to test it on.... A major part of this work is a general move to convert the low-level memory management to consistently use pageframe numbers. It's a bit schizo at present.. This patch was written by Martin Bligh. A version of this patch is in the 2.4 aa tree. It changes the unsigned longs node_start_paddr and zone_start_paddr to page frame numbers. This is necessary because a PAE address is 36 bits and cannot be represented in an unsigned long. - The per-node physical memory start address node_start_paddr becomes a pfn, node_start_pfn. - The per-zone physical memory start address zone_start_paddr becomes a pfn, zone_start_pfn. - free_area_init_node() takes a pfn rather than a physical address. Patricia has tested this patch on the following configurations: UP, SMP, SMP PAE, multiquad, multiquad PAE, multiquad DISCONTIGMEM, multiquad DISCONTIGMEM PAE.

With all work done by akpm in 2.5 Linus no more has a buffer cache in the traditional sense. Still we try to keep estimates about what would be the buffer cache size by keeping the number of pages indexed by block device inodes. This is broken not only because the old buffercache was also used for file data which is nowdays not hashed to block device inodes and thus makes every user of this data assume wrong numbers. Second is is possible to use block device pages not through the buffer_head interface (i.e. userspace block device nodes, possibly JFS also soon). In addition the atomic_t used for this bookkepping (buffermem_pages) causes cacheline bouncing on larger machines. This is the first patch of a series to get rid of it. It removes the useless output of supposedly buffer pages in show_mem(), which is used by the magic sysrq key code.

Si_meminfo() is basically the same for all architectures (mips is a little different by providing a value for the shared field that is different from the originial intent, I will come back to this later), so it makes to have just one instance of it:

Remove show_buffers(). It really has nothing to show any more. just buffermem_pages() - move that out into the callers. There's a lot of duplication in this code. better approach would be to remove all the duplicated code out in the architectures and implement generic show_memory_state(). Later.
