* [PATCH] unify PFN_* macrosDave Hansen2006-03-274-12/+10
| | | | | | | | | | | | | | | | | | | | Just about every architecture defines some macros to do operations on pfns. They're all virtually identical. This patch consolidates all of them. One minor glitch is that at least i386 uses them in a very skeletal header file. To keep away from #include dependency hell, I stuck the new definitions in a new, isolated header. Of all of the implementations, sh64 is the only one that varied by a bit. It used some masks to ensure that any sign-extension got ripped away before the arithmetic is done. This has been posted to that sh64 maintainers and the development list. Compiles on x86, x86_64, ia64 and ppc64.

| | | | | | | | | | | | | | | | | Helper functions for for_each_online_pgdat/for_each_zone look too big to be inlined. Speed of these helper macro itself is not very important. (inner loops are tend to do more work than this) This patch make helper function to be out-of-lined. inline out-of-line .text 005c0680 005bf6a0 005c0680 - 005bf6a0 = FE0 = 4Kbytes.

* [PATCH] for_each_online_pgdat: for_each_bootmemKAMEZAWA Hiroyuki2006-03-271-0/+1
| | | | | | | | | | | | | | | | Add a list_head to bootmem_data_t and make bootmems use it. bootmem list is sorted by node_boot_start. Only nodes against which init_bootmem() is called are linked to the list. (i386 allocates bootmem only from one node(0) not from all online nodes.) A summary: 1. for_each_online_pgdat() traverses all *online* nodes. 2. alloc_bootmem() allocates memory only from initialized-for-bootmem nodes.

* [PATCH] define for_each_online_pgdatKAMEZAWA Hiroyuki2006-03-272-51/+61
| | | | | | | | | | | | | | | | | | | | | | This patch defines for_each_online_pgdat() as a replacement of for_each_pgdat() Now, online nodes are managed by node_online_map. But for_each_pgdat() uses pgdat_link to iterate over all nodes(pgdat). This means management structure for online pgdat is duplicated. I think using node_online_map for for_each_pgdat() is simple and sane rather ather than pgdat_link. New macro is named as for_each_online_pgdat(). Following patch will fix callers of for_each_pgdat(). The bootmem allocater uses for_each_pgdat() before pgdat initialization. I don't think it's sane. Following patch will fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 3 memory models, FLATMEM, DISCONTIGMEM, SPARSEMEM. Each arch has its own page_to_pfn(), pfn_to_page() for each models. But most of them can use the same arithmetic. This patch adds asm-generic/memory_model.h, which includes generic page_to_pfn(), pfn_to_page() definitions for each memory model. When CONFIG_OUT_OF_LINE_PFN_TO_PAGE=y, out-of-line functions are used instead of macro. This is enabled by some archs and reduces text size.

* [PATCH] sched: new sched domain for representing multi-coreSiddha, Suresh B2006-03-276-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | Add a new sched domain for representing multi-core with shared caches between cores. Consider a dual package system, each package containing two cores and with last level cache shared between cores with in a package. If there are two runnable processes, with this appended patch those two processes will be scheduled on different packages. On such systems, with this patch we have observed 8% perf improvement with specJBB(2 warehouse) benchmark and 35% improvement with CFP2000 rate(with 2 users). This new domain will come into play only on multi-core systems with shared caches. On other systems, this sched domain will be removed by domain degeneration code. This new domain can be also used for implementing power savings policy (see OLS 2005 CMP kernel scheduler paper for more details.. I will post another patch for power savings policy soon) Most of the arch/* file changes are for cpu_coregroup_map() implementation.

* [PATCH] knfsd: Break the hard linkage from svc_expkey to svc_exportNeilBrown2006-03-271-16/+4
| | | | | | | | | | | | | | | | Current svc_expkey holds a pointer to the svc_export structure, so updates to that structure have to be in-place, which is a wart on the whole cache infrastruct. So we break that linkage and just do a second lookup. If this became a performance issue, it would be possible to put a direct link back in which was only used conditionally. i.e. when an object is replaced in the cache, we set a flag in the old object. When dereferencing the link from svc_expkey, if the flag is set, we drop the reference and do a fresh lookup.

* [PATCH] bitops: sh: make thread_info.flags an unsigned longAkinobu Mita2006-03-261-1/+1
| | | | | | | | | | | | | | | The test_bit() routines are defined to work on a pointer to unsigned long. But thread_info.flags is __u32 (unsigned int) on sh and it is passed to flag set/clear/test wrappers in include/linux/thread_info.h. So the compiler will print warnings. This patch changes to unsigned long instead.

| | | | | | | | | | | | Currently include/asm-generic/bitops.h is not referenced from anywhere. But it will be the benefit of those who are trying to port Linux to another architecture.
