* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] memory hotplug locking: node_size_lockDave Hansen2005-10-30
| | | | | | | | | | | | | | | | | | | | pgdat->node_size_lock is basically only neeeded in one place in the normal code: show_mem(), which is the arch-specific sysrq-m printing function. Strictly speaking, the architectures not doing memory hotplug do no need this locking in show_mem(). However, they are all included for completeness. This should also make any future consolidation of all of the implementations a little more straightforward. This lock is also held in the sparsemem code during a memory removal, as sections are invalidated. This is the place there pfn_valid() is made false for a memory area that's being removed. The lock is only required when doing pfn_valid() operations on memory which the user does not already have a reference on the page, such as in show_mem().

* [PATCH] mm: flush_tlb_range outside ptlockHugh Dickins2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | There was one small but very significant change in the previous patch: mprotect's flush_tlb_range fell outside the page_table_lock: as it is in 2.4, but that doesn't prove it safe in 2.6. On some architectures flush_tlb_range comes to the same as flush_tlb_mm, which has always been called from outside page_table_lock in dup_mmap, and is so proved safe. Others required a deeper audit: I could find no reliance on page_table_lock in any; but in ia64 and parisc found some code which looks a bit as if it might want preemption disabled. That won't do any actual harm, so pending a decision from the maintainers, disable preemption there. Remove comments on page_table_lock from flush_tlb_mm, flush_tlb_range and flush_tlb_page entries in cachetlb.txt: they were rather misleading (what generic code does is different from what usually happens), the rules are now changing, and it's not yet clear where we'll end up (will the generic tlb_flush_mmu happen always under lock? never under lock? or sometimes under and sometimes not?).

* [PATCH] mm: init_mm without ptlockHugh Dickins2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First step in pushing down the page_table_lock. init_mm.page_table_lock has been used throughout the architectures (usually for ioremap): not to serialize kernel address space allocation (that's usually vmlist_lock), but because pud_alloc,pmd_alloc,pte_alloc_kernel expect caller holds it. Reverse that: don't lock or unlock init_mm.page_table_lock in any of the architectures; instead rely on pud_alloc,pmd_alloc,pte_alloc_kernel to take and drop it when allocating a new one, to check lest a racing task already did. Similarly no page_table_lock in vmalloc's map_vm_area. Some temporary ugliness in __pud_alloc and __pmd_alloc: since they also handle user mms, which are converted only by a later patch, for now they have to lock differently according to whether or not it's init_mm. If sources get muddled, there's a danger that an arch source taking init_mm.page_table_lock will be mixed with common source also taking it (or neither take it). So break the rules and make another change, which should break the build for such a mismatch: remove the redundant mm arg from pte_alloc_kernel (ppc64 scrapped its distinct ioremap_mm in 2.6.13). Exceptions: arm26 used pte_alloc_kernel on user mm, now pte_alloc_map; ia64 used pte_alloc_map on init_mm, now pte_alloc_kernel; parisc had bad args to pmd_alloc and pte_alloc_kernel in unused USE_HPPA_IOREMAP code; ppc64 map_io_page forgot to unlock on failure; ppc mmu_mapin_ram and ppc64 im_free took page_table_lock for no good reason.

* [PATCH] mm: ia64 use expand_upwardsHugh Dickins2005-10-30
| | | | | | | | | | | | | | | ia64 has expand_backing_store function for growing its Register Backing Store vma upwards. But more complete code for this purpose is found in the CONFIG_STACK_GROWSUP part of mm/mmap.c. Uglify its #ifdefs further to provide expand_upwards for ia64 as well as expand_stack for parisc.

The test can be unnecessarily long (and occurs while holding the tasklist_lock). Especially long on a large system with thousands of active tasks. The ptrace caller (presumably a debugger) specifies the pid of its target and an address to peek or poke. But the debugger could be attached to several tasks. The idea of find_thread_for_addr() is to find whether the target address is in the RBS for any of those tasks. Currently it searches the thread-list of the target pid. If that search does not find a match, and the shared mm-struct's user count indicates that there are other tasks sharing this address space (a rare occurrence), a search is made of all the tasks in the system. Another approach can drastically shorten this procedure. It depends upon the fact that in order to peek or poke from/to any task, the debugger must first attach to that task. And when it does, the attached task is made a child of the debugger (is chained to its children list). Therefore we can search just the debugger's children list.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush_tlb_all() can be a scaling issue on large SGI Altix systems since it uses the global call_lock and always executes on all cpus. When a process enters flush_tlb_range() to purge TLBs for another process, it is possible to avoid flush_tlb_all() and instead allow sn2_global_tlb_purge() to purge TLBs only where necessary. This patch modifies flush_tlb_range() so that this case can be handled by platform TLB purge functions and updates ia64_global_tlb_purge() accordingly. sn2_global_tlb_purge() now calculates the region register value from the mm argument introduced with this patch.

This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Until 8250_acpi.c is removed, some systems will see serial ports reported twice (once from 8250_acpi.c and again from 8250_pnp.c). This is harmless. PNPACPI is still marked EXPERIMENTAL, but I'm not aware of any outstanding issues on ia64.
