Removes preemption requirement\n\nFrom: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n\nThis patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it\nwas impossible to deliver a signal to a spinning guest. We used\npreemption as a circumvention. The preemption notifiers called\nvcpu_load, which checked for pending signals and triggered a host\nintercept. But even with preemption, a sigkill was not delivered\nimmediately.\n\nThis patch changes the low level host interrupt handler to check for the\nSIE instruction, if TIF_WORK is set. In that case we change the\ninstruction pointer of the return PSW to rerun the vcpu_run loop. The kvm\ncode sees an intercept reason 0 if that happens. This patch adds accounting\nfor these types of intercept as well.\n\nThe advantages:\n- works with and without preemption\n- signals are delivered immediately\n- much better host latencies without preemption\n\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "59df83992b6ec962fdf69e4db4c18951499cc67c", "tree": "2f3fdac29d5b3a5b91d8bf6ce916dc54d2ea1c3f", "parents": [ "3f02c4e0e5d20884677a0259de42e553514534f9" ], "author": { "name": "H.

Instead, they had proposed to\nimplement it with an additional path through vm_normal_page(), using a bit in\nthe pte to determine whether or not the page should be refcounted:\n\nvm_normal_page()\n{\n\t...\n if (unlikely(vma-\u003evm_flags \u0026 (VM_PFNMAP|VM_MIXEDMAP))) {\n if (vma-\u003evm_flags \u0026 VM_MIXEDMAP) {\n#ifdef s390\n\t\t\tif (!mixedmap_refcount_pte(pte))\n\t\t\t\treturn NULL;\n#else\n if (!pfn_valid(pfn))\n return NULL;\n#endif\n goto out;\n }\n\t...\n}\n\nThis is fine, however if we are allowed to use a bit in the pte to determine\nrefcountedness, we can use that to _completely_ replace all the vma based\nschemes. So instead of adding more cases to the already complex vma-based\nscheme, we can have a clearly seperate and simple pte-based scheme (and get\nslightly better code generation in the process):\n\nvm_normal_page()\n{\n#ifdef s390\n\tif (!mixedmap_refcount_pte(pte))\n\t\treturn NULL;\n\treturn pte_page(pte);\n#else\n\t...\n#endif\n}\n\nAnd finally, we may rather make this concept usable by any architecture rather\nthan making it s390 only, so implement a new type of pte state for this.\nUnfortunately the old vma based code must stay, because some architectures may\nnot be able to spare pte bits. This makes vm_normal_page a little bit more\nugly than we would like, but the 2 cases are clearly seperate.\n\nSo introduce a pte_special pte state, and use it in mm/memory.c. It is\ncurrently a noop for all architectures, so this doesn\u0027t actually result in any\ncompiled code changes to mm/memory.o.\n\nBTW:\nI haven\u0027t put vm_normal_page() into arch code as-per an earlier suggestion.\nThe reason is that, regardless of where vm_normal_page is actually\nimplemented, the *abstraction* is still exactly the same. Also, while it\ndepends on whether the architecture has pte_special or not, that is the\nonly two possible cases, and it really isn\u0027t an arch specific function --\nthe role of the arch code should be to provide primitive functions and\naccessors with which to build the core code; pte_special does that. We do\nnot want architectures to know or care about vm_normal_page itself, and\nwe definitely don\u0027t want them being able to invent something new there\nout of sight of mm/ code. If we made vm_normal_page an arch function, then\nwe have to make vm_insert_mixed (next patch) an arch function too. So I\ndon\u0027t think moving it to arch code fundamentally improves any abstractions,\nwhile it does practically make the code more difficult to follow, for both\nmm and arch developers, and easier to misuse.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c71799c1f404c6e4f34fa64e6be39cd6149e5019", "tree": "cfc9b0d49e02156b0b9931363c21e957ff9caae1", "parents": [ "f603f0731f43421403160f5f8b12e90f2e51f064" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Fri Apr 04 16:03:34 2008 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Sun Apr 27 12:01:00 2008 +0300" }, "message": "KVM: s390: Improve pgste accesses\n\nThere is no need to use interlocked updates when the rcp\nlock is held.

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": "922a70d327bd4b11342c2afd08e20d35f52064c3", "tree": "aff7e43fa600363128c15c4b9a1ceba3869aac15", "parents": [ "3eb056764dd806bbe84eb604e45e7470feeaafd8" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Feb 08 04:19:26 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:29 2008 -0800" }, "message": "aout: move STACK_TOP[_MAX] to asm/processor.h\n\nMove STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they\u0027re\nrequired whether or not A.OUT format is available.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.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": "596f56018df3ed7de20f6038f72177b3674ebbd4", "tree": "8d3956e81dd291e5c01d27d76d5b0dfb9febd38b", "parents": [ "aa7738a5f503abea5445cdd8cc2d501502c748ae" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Fri Feb 08 04:18:40 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:24 2008 -0800" }, "message": "tty: s390 support for termios2.\n\nBackend for s390.\n\nAcked-by: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "df5f8314ca30d6a76735748e5ba4ca9809c0f434", "tree": "e0a6157b1666a320e69586a81c77a3fe83b36a2a", "parents": [ "a56d3fc74c0178c5f41c48315604d62cff4e746d" ], "author": { "name": "Eric W.
