* [PATCH] make each arch use mm/KconfigDave Hansen2005-06-2323-10/+66
| | | | | | | | | | | | | | For all architectures, this just means that you'll see a "Memory Model" choice in your architecture menu. For those that implement DISCONTIGMEM, you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool y" and make your users select DISCONTIGMEM right out of the new choice menu. The only disadvantage might be if you have some specific things that you need in your help option to explain something about DISCONTIGMEM.

* [PATCH] sparsemem base: teach discontig about sparse rangesDave Hansen2005-06-232-1/+15
| | | | | | | | | | | discontig.c has some assumptions that mem_map[]s inside of a node are contiguous. Teach it to make sure that each region that it's bringing online is actually made up of valid ranges of ram.

* [PATCH] sparsemem base: simple NUMA remap space allocatorDave Hansen2005-06-232-28/+36
| | | | | | | | | | | | | | | | | | | Introduce a simple allocator for the NUMA remap space. This space is very scarce, used for structures which are best allocated node local. This mechanism is also used on non-NUMA ia64 systems with a vmem_map to keep the pgdat->node_mem_map initialized in a consistent place for all architectures. Issues: o alloc_remap takes a node_id where we might expect a pgdat which was intended to allow us to allocate the pgdat's using this mechanism; which we do not yet do. Could have alloc_remap_node() and alloc_remap_nid() for this purpose.

* [PATCH] sparsemem base: early_pfn_to_nid() (works before sparse is initialized)Dave Hansen2005-06-231-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following four patches provide the last needed changes before the introduction of sparsemem. For a more complete description of what this will do, please see this patch: http://www.sr71.net/patches/2.6.11/2.6.11-bk7-mhp1/broken-out/B-sparse-150-sparsemem.patch or previous posts on the subject: http://marc.theaimsgroup.com/?t=110868540700001&r=1&w=2 http://marc.theaimsgroup.com/?l=linux-mm&m=109897373315016&w=2 Three of these are i386-only, but one of them reorganizes the macros used to manage the space in page->flags, and will affect all platforms. There are analogous patches to the i386 ones for ppc64, ia64, and x86_64, but those will be submitted by the normal arch maintainers. The combination of the four patches has been test-booted on a variety of i386 hardware, and compiled for ppc64, i386, and x86-64 with about 17 different .configs. It's also been runtime-tested on ia64 configs (with more patches on top). This patch: We _know_ which node pages in general belong to, at least at a very gross level in node_{start,end}_pfn[]. Use those to target the allocations of pages.

* [PATCH] remove non-DISCONTIG use of pgdat->node_mem_mapDave Hansen2005-06-237-22/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch effectively eliminates direct use of pgdat->node_mem_map outside of the DISCONTIG code. On a flat memory system, these fields aren't currently used, neither are they on a sparsemem system. There was also a node_mem_map(nid) macro on many architectures. Its use along with the use of ->node_mem_map itself was not consistent. It has been removed in favor of two new, more explicit, arch-independent macros: pgdat_page_nr(pgdat, pagenr) nid_page_nr(nid, pagenr) I called them "pgdat" and "nid" because we overload the term "node" to mean "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways. I believe the newer names are much clearer. These macros can be overridden in the sparsemem case with a theoretically slower operation using node_start_pfn and pfn_to_page(), instead. We could make this the only behavior if people want, but I don't want to change too much at once. One thing at a time. This patch removes more code than it adds. Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386 generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64. Full list here: http://sr71.net/patches/2.6.12/2.6.12-rc1-mhp2/configs/ Boot tested on NUMAQ, x86 SMP and ppc64 power4/5 LPARs.

It walks the page table assuming PAGE_SIZE. Thus when taking a fault triggered from hugetlb address, it would not calculate the pgd/pmd/pte address correctly and thus result an incorrect invocation of ia64_do_page_fault(). In there, kernel will signal SIGBUS and application dies (The faulting address is perfectly legal and we have a valid pte for the corresponding user hugetlb address as well). This patch fix the described kernel bug. Since nested_dtlb_miss is a rare event and a slow path anyway, I'm making the change without #ifdef CONFIG_HUGETLB_PAGE for code readability.

The memory size is contained in a structure created by an sclp call. The kernel accesses the field with a LH instrution which performs a sign extension of a 16 bit word. In the case of a memory size with bit 2^15 set this results in a very large value and the memory detection just loops for a long time. In addition if more then 64 GB are used on a 64 bit system the memory size is read from an incorrect storage location. Use zero-extention to read the 16 bit memory size and the correct offset to read the 4 byte memory size on 64 bit.

This is needed because ->shutdown and/or ->disable are only called when the last "action" for that irq is removed. Instead, for UML shared IRQs (UML IRQs are very often, if not always, shared), for each dev_id some setup is done, which must be cleared on the release of that fd. For instance, for each open console a new instance (i.e. new dev_id) of the same IRQ is requested(). Exactly, a fd is stored in an array (pollfds), which is after read by a host thread and passed to poll(). Each event registered by poll() triggers an interrupt. So, for each free_irq() we must remove the corresponding host fd from the table, which we do via this -release() method. In this patch we add an appropriate hook for this, and remove all uses of it by pointing the hook to the said procedure; this is safe to do since the said procedure. Also some cosmetic improvements are included. This is heavily based on some work by Chris Wedgwood, which however didn't get the patch merged for something I'd call a "misunderstanding" (the need for this patch wasn't cleanly explained, thus adding the generic hook was felt as undesirable).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We dont use the hardware referenced and changed bits and setting them early avoids a store to memory. We already do this for userspace hptes but not kernel ones. Do it.

* | | | [PATCH] ppc64: tidy up vio devices fake parentStephen Rothwell2005-06-211-21/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we dynamically allocate the fake parent device for all devices on the vio bus. This patch statically allocates it. This also allows us to reuse it for the iSeries "generic" vio device (that is used for passing to dma routines when communicating with the hypervisor without a device involved). Also unexport vio_bus_type as it is never used in modules.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows iSeries to build with CONFIG_PCI=n. This is useful for partitions that have only virtual I/O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch just removes some dead code, fixes messages that referred to the file this code used to be in and inserts XmPciLpEvent_init into its caller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch just merges XmPciLpEvent.c into iSeries_irq.c (the only caller of its only external function).
