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": "5e5419734c8719cbc01af959ad9c0844002c0df5", "tree": "a075dca3f719946689efa0245464855cbf2a20ce", "parents": [ "9f8f2172537de7af0b0fbd33502d18d52b1339bc" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Feb 04 22:29:14 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:18 2008 -0800" }, "message": "add mm argument to pte/pmd/pud/pgd_free\n\n(with Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e)\n\nThe pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as\nfirst argument.

For\nexample, in arch/alpha/mm/fault.c:\n\n\"\n if (cause \u003c 0) {\n if (!(vma-\u003evm_flags \u0026 VM_EXEC))\n goto bad_area;\n } else if (!cause) {\n /* Allow reads even for write-only mappings */\n if (!(vma-\u003evm_flags \u0026 (VM_READ | VM_WRITE)))\n goto bad_area;\n } else {\n if (!(vma-\u003evm_flags \u0026 VM_WRITE))\n goto bad_area;\n }\n\"\n\nThus, this patch brings other architectures which do not support write only\nmappings in-line and consistent with the rest. I\u0027ve verified the patch on\nia64, x86_64 and x86.\n\nAdditional discussion:\n\nSeveral architectures, including x86, can not support write-only mappings.\nThe pte for x86 reserves a single bit for protection and its two states are\nread only or read/write. Thus, write only is not supported in h/w.\n\nCurrently, if i \u0027mmap\u0027 a page write-only, the first read attempt on that page\ncreates a page fault and will SEGV. That check is enforced in\narch/blah/mm/fault.c. However, if i first write that page it will fault in\nand the pte will be set to read/write. Thus, any subsequent reads to the page\nwill succeed. It is this inconsistency in behavior that this patch is\nattempting to address. Furthermore, if the page is swapped out, and then\nbrought back the first read will also cause a SEGV. Thus, any arbitrary read\non a page can potentially result in a SEGV.\n\nAccording to the SuSv3 spec, \"if the application requests only PROT_WRITE, the\nimplementation may also allow read access.\" Also as mentioned, some\narchtectures, such as alpha, shown above already take the approach that i am\nsuggesting.\n\nThe counter-argument to this raised by Arjan, is that the kernel is enforcing\nthe write only mapping the best it can given the h/w limitations. This is\ntrue, however Alan Cox, and myself would argue that the inconsitency in\nbehavior, that is applications can sometimes work/sometimes fails is highly\nundesireable. If you read through the thread, i think people, came to an\nagreement on the last patch i posted, as nobody has objected to it...\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Geert Uytterhoeven \u003cgeert@linux-m68k.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: Andi Kleen \u003cak@muc.de\u003e\nAcked-by: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Kazumoto Kojima \u003ckkojima@rr.iij4u.or.jp\u003e\nCc: Ian Molton \u003cspyro@f2s.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c67c3cb4c99fb2ee63c8733943c353d745f45b84", "tree": "5628da22a723aab1d11dfbedda264f3f65addc21", "parents": [ "c713216deebd95d2b0ab38fef8bb2361c0180c2d" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Wed Sep 27 01:49:49 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 27 08:26:11 2006 -0700" }, "message": "[PATCH] Have Power use add_active_range() and free_area_init_nodes()\n\nSize zones and holes in an architecture independent manner for Power.\n\n[judith@osdl.org: build fix]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: \"Keith Mannthey\" \u003ckmannth@gmail.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6ab3d5624e172c553004ecc862bfeac16d9d68b7", "tree": "6d98881fe91fd9583c109208d5c27131b93fa248", "parents": [ "e02169b682bc448ccdc819dc8639ed34a23cedd8" ], "author": { "name": "Jörn Engel", "email": "joern@wohnheim.fh-wedel.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "message": "Remove obsolete #include \u003clinux/config.h\u003e\n\nSigned-off-by: Jörn Engel \u003cjoern@wohnheim.fh-wedel.de\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n" }, { "commit": "31925323b1b51bb65db729e029472a8b1f635b7d", "tree": "e902a594508124adc74d07018834f5dce49af052", "parents": [ "430644312810645a6e05855db50a978df9ba3ad3" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Jun 13 13:43:00 2006 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Jun 13 13:43:00 2006 +1000" }, "message": "powerpc: Fix some missed ppc32 mm-\u003econtext.id conversions\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "6218a761bbc27acc65248c80024875bcc06d52b1", "tree": "59a278c4c189f838ede99de5fd46241d1923f52b", "parents": [ "050613545b389825c1f5beb67fa2667b727f866d" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Sun Jun 11 14:15:17 2006 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Sun Jun 11 14:15:17 2006 +1000" }, "message": "powerpc: add context.vdso_base for 32-bit too\n\nThis adds a vdso_base element to the mm_context_t for 32-bit compiles\n(both for ARCH\u003dpowerpc and ARCH\u003dppc).
