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": "2688905e6a9b3647bf7b452cb0ff2bdb166bd8fe", "tree": "389b9c29eaaa7eb49a9e7d3bb601959fb9d27af8", "parents": [ "c0a18111e571138747a98af18b3a2124df56a0d1" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:22:52 2008 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:23:00 2008 +0200" }, "message": "[S390] s390: Optimize user and work TIF check\n\nOn return from syscall or interrupt, we have to check if we return to\nuserspace (likely) and if there is work todo (less likely) to decide\nif we handle the work.

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": "df5f8314ca30d6a76735748e5ba4ca9809c0f434", "tree": "e0a6157b1666a320e69586a81c77a3fe83b36a2a", "parents": [ "a56d3fc74c0178c5f41c48315604d62cff4e746d" ], "author": { "name": "Eric W.
