There was a test of need_resched followed by a schedule inside the\nloop, but that didn\u0027t help and it\u0027s the wrong way to work anyway.\n\nThe right way is to ask for an interrupt when there is input available from\nthe host and handle it then rather than polling.\n\nNow, when the host\u0027s /dev/random returns -EAGAIN, the driver asks for a wakeup\nwhen there\u0027s randomness available again and sleeps. The interrupt routine\njust wakes up whatever processes are sleeping on host_read_wait.\n\nThere is an atomic_t, host_sleep_count, which counts the number of processes\nwaiting for randomness. When this reaches zero, the interrupt is disabled.\n\nAn added complication is that async I/O notification was only recently added\nto /dev/random (by me), so essentially all hosts will lack it. So, we use the\nsigio workaround here, which is to have a separate thread poll on the\ndescriptor and send an interrupt when there is input on it. This mechanism is\nactivated when a process gets -EAGAIN (activating this multiple times is\nharmless, if a bit wasteful) and deactivated by the last process still\nwaiting.\n\nThe module name was changed from \"random\" to \"hw_random\" in order for udev to\nrecognize it.\n\nThe sigio workaround needed some changes. sigio_broken was added for cases\nwhen we know that async notification doesn\u0027t work.

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.

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": "64ac24e738823161693bf791f87adc802cf529ff", "tree": "19c0b0cf314d4394ca580c05b86cdf874ce0a167", "parents": [ "e48b3deee475134585eed03e7afebe4bf9e0dba9" ], "author": { "name": "Matthew Wilcox", "email": "matthew@wil.cx", "time": "Fri Mar 07 21:55:58 2008 -0500" }, "committer": { "name": "Matthew Wilcox", "email": "willy@linux.intel.com", "time": "Thu Apr 17 10:42:34 2008 -0400" }, "message": "Generic semaphore implementation\n\nSemaphores are no longer performance-critical, so a generic C\nimplementation is better for maintainability, debuggability and\nextensibility.

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": "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.

This means that this bit of arch\n code will be stored in the appropriate A.OUT binfmt module rather than\n the core kernel.\n\n (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it\u0027s not\n needed) and FRV.\n\nThis patch depends on the previous patch to move STACK_TOP[_MAX] out of\nasm/a.out.h and into asm/processor.h as they\u0027re required whether or not A.OUT\nformat is available.\n\n[jdike@addtoit.com: uml: re-remove accidentally restored code]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\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": "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": "01ac835fdd121f36dded404af15225101f6ccee3", "tree": "7c147e37003fdad5525ce4b036917a29d9cdd1a2", "parents": [ "2278c5ac9d39699bac44250b9c532de0c02cb16a" ], "author": { "name": "Daniel Walker", "email": "dwalker@mvista.com", "time": "Mon Feb 04 22:31:26 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:31 2008 -0800" }, "message": "uml: LDT mutex conversion\n\nThe ldt.semaphore conforms to the new struct mutex requirments, so I converted\nit to use the new API and changed the name.\n\nSigned-off-by: Daniel Walker \u003cdwalker@mvista.com\u003e\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": "7281ff952c7b3cbefb14847460e5fe73a2d240e4", "tree": "f2f7b0c103b2c860f6be18a650098fca9a724197", "parents": [ "438ee6798cd8bfc44da725fca846367e19d86652" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:31:19 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:31 2008 -0800" }, "message": "uml: add back CONFIG_HZ\n\navoid-overflows-in-kernel-timec.patch makes CONFIG_HZ necessary for a\nsuccessful build.

This allows the removal of a truly nasty kludge to make\nsure that mm-\u003enr_ptes was correct in exit_mmap. The underlying problem was\nalways that the stubs, which have ptes, and thus allocated a page table,\nweren\u0027t covered by a VMA.\n\nThis patch fixes that by using install_special_mapping in arch_dup_mmap and\nactivate_context to create the VMA. 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. However, that\nextends the stub VMA by the amount removed from the stack VMA.\n\nTo avoid this problem, the stubs were moved to a different fixed location at\nthe start of the address space.\n\nThe init_stub_pte calls were moved from init_new_context to arch_dup_mmap\nbecause I was occasionally seeing arch_dup_mmap not being called, causing\nexit_mmap to die. 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": "ca77b555c0aafa3070fbb67592abaaa1b8d31913", "tree": "fb0b42c68879599b65dc897153923ffadca408ab", "parents": [ "655e4ed0c521dcfdbf1c5a79da971560e6733527" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:55 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: add virt_to_pte\n\nTurn um_virt_to_phys into virt_to_pte, cleaning up a horrid interface.\n\nIt\u0027s also made non-static and declared in pgtable.h because it\u0027ll be\nneeded when the stubs get a vma.\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": "655e4ed0c521dcfdbf1c5a79da971560e6733527", "tree": "8b0cf794410c9e632b9ee65b8e0750621d9c96ce", "parents": [ "a5a678c80beac4d163babda243a27eeb9c89bd89" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:55 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: fix page table data sizes\n\nGet the sizes of various pieces of data right when using three-level\npage tables. pgd and pmd entries remain at 32 bits in a 32-bit\ncompilation because page tables will remain in low memory.

This differs from i386 in having the entire\ninterrupt run on a separate stack rather than starting on the normal kernel\nstack and switching over once some preparation has been done. The underlying\nmechanism, is of course, sigaltstack.\n\nAnother difference is that interrupts that happen in userspace are handled on\nthe normal kernel stack. These cause a wait wakeup instead of a signal\ndelivery so there is no point in trying to switch stacks for these. There\u0027s\nno other stuff on the stack, so there is no extra stack consumption.\n\nThis quirk makes it possible to have the entire interrupt run on a separate\nstack - process preemption (and calls to schedule()) happens on a normal\nkernel stack. If we enable CONFIG_PREEMPT, this will need to be rethought.\n\nThe IRQ stack for CPU 0 is declared in the same way as the initial kernel\nstack. IRQ stacks for other CPUs will be allocated dynamically.\n\nAn extra field was added to the thread_info structure. When the active\nthread_info is copied to the IRQ stack, the real_thread field points back to\nthe original stack. This makes it easy to tell where to copy the thread_info\nstruct back to when the interrupt is finished. It also serves as a marker of\na nested interrupt. It is NULL for the first interrupt on the stack, and\nnon-NULL for any nested interrupts.\n\nCare is taken to behave correctly if a second interrupt comes in when the\nthread_info structure is being set up or taken down. I could just disable\ninterrupts here, but I don\u0027t feel like giving up any of the performance gained\nby not flipping signals on and off.\n\nIf an interrupt comes in during these critical periods, the handler can\u0027t run\nbecause it has no idea what shape the stack is in. So, it sets a bit for its\nsignal in a global mask and returns. The outer handler will deal with this\nsignal itself.\n\nAtomicity is had with xchg. A nested interrupt that needs to bail out will\nxchg its signal mask into pending_mask and repeat in case yet another\ninterrupt hit at the same time, until the mask stabilizes.\n\nThe outermost interrupt will set up the thread_info and xchg a zero into\npending_mask when it is done. At this point, nested interrupts will look at\n-\u003ereal_thread and see that no setup needs to be done. They can just continue\nnormally.\n\nSimilar care needs to be taken when exiting the outer handler. If another\ninterrupt comes in while it is copying the thread_info, it will drop a bit\ninto pending_mask. The outer handler will check this and if it is non-zero,\nwill loop, set up the stack again, and handle the interrupt.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f", "tree": "b66a624ba68766282fa0ddb509ff641552703da4", "parents": [ "dd2a345f8f002845636dbf5d2d768bb5cd8a5f59" ], "author": { "name": "Fernando Luis Vazquez Cao", "email": "fernando@oss.ntt.co.jp", "time": "Wed May 09 02:33:25 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:48 2007 -0700" }, "message": "Remove hardcoding of hard_smp_processor_id on UP systems\n\nWith the advent of kdump, the assumption that the boot CPU when booting an UP\nkernel is always the CPU with a particular hardware ID (often 0) (usually\nreferred to as BSP on some architectures) is not valid anymore.
