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": "1eb114112381eb66ebacdace1b6e70d30d603f9c", "tree": "3b97926b1a90aa996f99a23281809c3d960fd3d8", "parents": [ "7fa3031500ec9b0a7460c8c23751799006ffee74" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Feb 08 04:19:29 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:30 2008 -0800" }, "message": "aout: remove unnecessary inclusions of {asm, linux}/a.out.h\n\nRemove now unnecessary inclusions of {asm,linux}/a.out.h.\n\n[akpm@linux-foundation.org: fix alpha build]\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": "7fa3031500ec9b0a7460c8c23751799006ffee74", "tree": "2a7e9202b35a39dc8217e95825263c0629e67e35", "parents": [ "b0b933c08bd5fd053bbba8ba6387f543be03d49f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Feb 08 04:19:28 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:30 2008 -0800" }, "message": "aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUT\n\nSuppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set.\n\nNot all architectures support the A.OUT binfmt, so the ELF binfmt should not\nbe permitted to go looking for A.OUT libraries to load in such a case.

The stubs have to be moved, since\nshift_arg_pages seems to assume that the stack is the only VMA present at that\npoint during exec, and uses vma_adjust to fiddle its VMA.

Rather than figure out what was really happening, I decided\nit was cleaner to just move the calls so that there\u0027s no doubt that both the\npte and VMA creation happen, no matter what. arch_exit_mmap is used to clear\nthe stub ptes at exit time.\n\nThe STUB_* constants in as-layout.h no longer depend on UM_TASK_SIZE, that\nthat definition is removed, along with the comments complaining about gcc.\n\nBecause the stubs are no longer at the top of the address space, some care is\nneeded while flushing TLBs. update_pte_range checks for addresses in the stub\nrange and skips them. flush_thread now issues two unmaps, one for the range\nbefore STUB_START and one for the range after STUB_END.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "42a2b54ce8c7b9d4f418995a7950e7e2e15e52ce", "tree": "30bcb0ea0a4ee6d5091b1b9a85589cff8b1863fc", "parents": [ "b7c000cbc4f1fa7b82efa95b34f00c2adbeaa3fe" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:31:00 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:29 2008 -0800" }, "message": "uml: clean up TASK_SIZE usage\n\nClean up the calculation and use of the usable address space size on the host.\n\ntask_size is gone, replaced with TASK_SIZE, which is calculated from\nCONFIG_TOP_ADDR. get_kmem_end and set_task_sizes_skas are also gone.\n\nhost_task_size, which refers to the entire address space usable by the UML\nkernel and which may be larger than the address space usable by a UML process,\nsince that has to end on a pgdir boundary, is replaced by CONFIG_TOP_ADDR.\n\nSTACK_TOP is now TASK_SIZE minus the two stub pages.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3e6f2ac480ce398ade2fd6b5e02d00d1265f1e0f", "tree": "25f5589189170c20a765d4e6f0c56b42ad58ea20", "parents": [ "d25f2e1235aab716c9fd6ba36c42503627a3a0e3" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:58 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: kill processes instead of panicing kernel\n\nUML was panicing in the case of failures of libc calls which shouldn\u0027t happen.\n This is an overreaction since a failure from libc doesn\u0027t normally mean that\nkernel data structures are in an unknown state. Instead, the current process\nshould just be killed if there is no way to recover.\n\nThe case that prompted this was a failure of PTRACE_SETREGS restoring the same\nstate that was read by PTRACE_GETREGS. It appears that when a process tries\nto load a bogus value into a segment register, it segfaults (as expected) and\nthe value is actually loaded and is seen by PTRACE_GETREGS (not expected).\n\nThis case is fixed by forcing a fatal SIGSEGV on the process so that it\nimmediately dies. fatal_sigsegv was added for this purpose. It was declared\nas noreturn, so in order to pursuade gcc that it actually does not return, I\nadded a call to os_dump_core (and declared it noreturn) so that I get a core\nfile if somehow the process survives.\n\nAll other calls in arch/um/os-Linux/skas/process.c got the same treatment,\nwith failures causing the process to die instead of a kernel panic, with some\nexceptions.\n\nuserspace_tramp exits with status 1 if anything goes wrong there.

This causes a problem because when handle_signal goes around\nthe loop, sig will be zero, and to_irq_stack will duly set bit zero in the\nreturned mask, faking handle_signal into believing that it shouldn\u0027t tear\ndown the IRQ stack and return thread_info pointers back to their original\nvalues.\n\nThis will eventually cause a crash, as the IRQ stack thread_info will\ncontinue pointing to the original task_struct and an interrupt will look\ninto it after it has been freed.\n\nThe fix is to stop passing a signal number into to_irq_stack. Rather, the\npending signals mask is initialized beforehand with the bit for sig already\nset. References to sig in to_irq_stack can be replaced with references to\nthe mask.\n\n[akpm@linux-foundation.org: use UL]\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c7ec16da5adc1c1b341b2a83bde7add17dcf811a", "tree": "4e11748671da5c83c894f1fe96ce999f33b52e7d", "parents": [ "641916881322a2dee5b120d509a3bdd05a502510" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Thu Aug 30 23:56:17 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Aug 31 01:42:22 2007 -0700" }, "message": "uml: fix linker script alignment bugs\n\nFix a class of bugs in the UML linker scripts which caused section boundary\nvariables to sometimes not line up with their sections.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4e950f6f0189f65f8bf069cf2272649ef418f5e4", "tree": "95710bedf2a5aa3b61002f3399e0950192fdd504", "parents": [ "673d5b43daa00b42759cecc6b0760b8bf6be80d2" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Jul 30 02:36:13 2007 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sun Jul 29 17:09:29 2007 -0700" }, "message": "Remove fs.h from mm.h\n\nRemove fs.h from mm.h.
