This regression is tracked at:\n\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d10082\n\nSLB misses at such points shouldn\u0027t happen because the kernel stack is\nthe only memory accessed other than things in the first segment of the\nlinear mapping (which is mapped at all times by entry 0 of the SLB).\nThe context switch code ensures that SLB entry 2 covers the kernel\nstack, if it is not already covered by entry 0. None of entries 0\nto 2 are ever replaced by the SLB miss handler.\n\nWhere this went wrong is that the context switch code assumes it\ndoesn\u0027t have to write to SLB entry 2 if the new kernel stack is in the\nsame segment as the old kernel stack, since entry 2 should already be\ncorrect. However, when we start up a secondary cpu, it calls\nslb_initialize, which doesn\u0027t set up entry 2. This is correct for\nthe boot cpu, where we will be using a stack in the kernel BSS at this\npoint (i.e. init_thread_union), but not necessarily for secondary\ncpus, whose initial stack can be allocated anywhere. This doesn\u0027t\ncause any immediate problem since the SLB miss handler will just\ncreate an SLB entry somewhere else to cover the initial stack.\n\nIn fact it\u0027s possible for the cpu to go quite a long time without SLB\nentry 2 being valid. Eventually, though, the entry created by the SLB\nmiss handler will get overwritten by some other entry, and if the next\naccess to the stack is at an unrecoverable point, we get the crash.\n\nThis fixes the problem by making slb_initialize create a suitable\nentry for the kernel stack, if we are on a secondary cpu and the stack\nisn\u0027t covered by SLB entry 0. This requires initializing the\nget_paca()-\u003ekstack field earlier, so I do that in smp_create_idle\nwhere the current field is initialized. This also abstracts a bit of\nthe computation that mk_esid_data in slb.c does so that it can be used\nin slb_initialize.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "bbea34606269efedf7d12c608924b47bafb344f5", "tree": "161e7cc2cd5aa03586603383ce47227532a1a648", "parents": [ "5be661a28b12aa43cc83ba935ba2b2c273d0da45" ], "author": { "name": "Geoff Levand", "email": "geoffrey.levand@am.sony.com", "time": "Thu May 01 08:24:58 2008 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri May 02 15:00:44 2008 +1000" }, "message": "[POWERPC] Fix slb.c compile warnings\n\nArrange for a syntax check to always be done on the powerpc/mm/slb.c\nDBG() macro by defining it to pr_debug() for non-debug builds.\n\nAlso, fix these related compile warnings:\n\n slb.c:273: warning: format \u0027%04x\u0027 expects type \u0027unsigned int\u0027, but argument 2 has type \u0027long unsigned int\n slb.c:274: warning: format \u0027%04x\u0027 expects type \u0027unsigned int\u0027, but argument 2 has type \u0027long unsigned int\u0027\n\nSigned-off-by: Geoff Levand \u003cgeoffrey.levand@am.sony.com\u003e\nAcked-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "9d88a2eb6e05c07aa0d484b8fa1372722fa921d0", "tree": "782b288099fbd96ed779c033f2c1322ff1822950", "parents": [ "98d5c21c812e4e3b795f5bd912f407ed7c5e4e38" ], "author": { "name": "Badari Pulavarty", "email": "pbadari@us.ibm.com", "time": "Fri Apr 18 13:33:53 2008 -0700" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Apr 29 15:57:53 2008 +1000" }, "message": "[POWERPC] Provide walk_memory_resource() for powerpc\n\nProvide walk_memory_resource() for 64-bit powerpc.

These sub-page\npage tables are required to properly support the s390 virtualization\ninstruction with KVM. The SIE instruction requires that the page tables\nhave 256 page table entries (pte) followed by 256 page status table entries\n(pgste). The pgstes are only required if the process is using the SIE\ninstruction. The pgstes are updated by the hardware and by the hypervisor\nfor a number of reasons, one of them is dirty and reference bit tracking.\nTo avoid wasting memory the standard pte table allocation should return\n1K/2K (31/64 bit) and 2K/4K if the process is using SIE.\n\nProblem: Page size on s390 is 4K, page table size is 1K or 2K. That means\nthe s390 version for pte_alloc_one cannot return a pointer to a struct\npage. Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one\ncannot return a pointer to a pte either, since that would require more than\n32 bit for the return value of pte_alloc_one (and the pte * would not be\naccessible since its not kmapped).\n\nSolution: The only solution I found to this dilemma is a new typedef: a\npgtable_t. For s390 pgtable_t will be a (pte *) - to be introduced with a\nlater patch. For everybody else it will be a (struct page *). The\nadditional problem with the initialization of the ptl lock and the\nNR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and\na destructor pgtable_page_dtor. The page table allocation and free\nfunctions need to call these two whenever a page table page is allocated or\nfreed. pmd_populate will get a pgtable_t instead of a struct page pointer.\n To get the pgtable_t back from a pmd entry that has been installed with\npmd_populate a new function pmd_pgtable is added. It replaces the pmd_page\ncall in free_pte_range and apply_to_pte_range.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a99824f327c748b2753f4fa570eb1fefcd6a9c4d", "tree": "47c6df061ade21ce7ebae43b31a39e882c90cf2b", "parents": [ "1482471d19e77d794012dbacaa65c44ceaae37bb" ], "author": { "name": "Badari Pulavarty", "email": "pbadari@us.ibm.com", "time": "Tue Feb 05 00:10:18 2008 -0800" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Feb 08 19:52:48 2008 +1100" }, "message": "[POWERPC] Add arch-specific walk_memory_remove() for 64-bit powerpc\n\nwalk_memory_resource() verifies if there are holes in a given memory\nrange, by checking against /proc/iomem.

Of course,\nthe emulator can emulate the MMU by checking and possibly remapping\nthe address for each memory access in software, but that is pretty\nslow.\n\nThis provides a facility for such programs to control the access\npermissions on individual 4k sub-pages of 64k pages. The idea is\nthat the emulator supplies an array of protection masks to apply to a\nspecified range of virtual addresses. These masks are applied at the\nlevel where hardware PTEs are inserted into the hardware page table\nbased on the Linux PTEs, so the Linux PTEs are not affected. Note\nthat this new mechanism does not allow any access that would otherwise\nbe prohibited; it can only prohibit accesses that would otherwise be\nallowed. This new facility is only available on 64-bit PowerPC and\nonly when the kernel is configured for 64k pages.\n\nThe masks are supplied using a new subpage_prot system call, which\ntakes a starting virtual address and length, and a pointer to an array\nof protection masks in memory. The array has a 32-bit word per 64k\npage to be protected; each 32-bit word consists of 16 2-bit fields,\nfor which 0 allows any access (that is otherwise allowed), 1 prevents\nwrite accesses, and 2 or 3 prevent any access.\n\nImplicit in this is that the regions of the address space that are\nprotected are switched to use 4k hardware pages rather than 64k\nhardware pages (on machines with hardware 64k page support). In fact\nthe whole process is switched to use 4k hardware pages when the\nsubpage_prot system call is used, but this could be improved in future\nto switch only the affected segments.\n\nThe subpage protection bits are stored in a 3 level tree akin to the\npage table tree. The top level of this tree is stored in a structure\nthat is appended to the top level of the page table tree, i.e., the\npgd array. Since it will often only be 32-bit addresses (below 4GB)\nthat are protected, the pointers to the first four bottom level pages\nare also stored in this structure (each bottom level page contains the\nprotection bits for 1GB of address space), so the protection bits for\naddresses below 4GB can be accessed with one fewer loads than those\nfor higher addresses.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "4ec161cf73bc0b4e5c36843638ef9171896fc0b9", "tree": "fd8d5c652bbc54f54e0b880a7540ce387ee1f34d", "parents": [ "5b14e5f9ddbb1bd32a876cac75f5f3ecfd353063" ], "author": { "name": "Jon Tollefson", "email": "kniht@linux.vnet.ibm.com", "time": "Fri Jan 04 09:59:50 2008 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Thu Jan 17 14:57:36 2008 +1100" }, "message": "[POWERPC] Add hugepagesz boot-time parameter\n\nThis adds the hugepagesz boot-time parameter for ppc64.
