To fix this, we add a register to note if we\u0027ve already\nsaved the registers once, and skip doing it on additional passes\nthrough the loop. To avoid a performance hit from the couple of\nextra instructions involved, I modified the GET_THREAD_INFO() macro\nto be guaranteed to be one instruction, then bundled it with adjacent\ninstructions, yielding an overall net savings.\n\nReported-By: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "05ef1b79d46347f94d9a78214cc745046c03e45a", "tree": "4e073d0958c86a1d1292c0563f706d5ee6091863", "parents": [ "a99cd1125189aaf31a7ee505d6208143482119eb" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Wed Apr 25 12:45:26 2012 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Wed Apr 25 12:45:26 2012 -0400" }, "message": "arch/tile: fix a couple of functions that should be __init\n\nThey were marked __devinit by mistake, causing some warnings at link time.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "6be5ceb02e98eaf6cfc4f8b12a896d04023f340d", "tree": "f34de1392300bbf63549f4eeb20f7606d6f7b1f9", "parents": [ "a46ef99d80817a167477ed1c8b4d90ee0c2e726f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 20 17:13:58 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 20 17:29:13 2012 -0700" }, "message": "VM: add \"vm_mmap()\" helper function\n\nThis continues the theme started with vm_brk() and vm_munmap():\nvm_mmap() does the same thing as do_mmap(), but additionally does the\nrequired VM locking.\n\nThis uninlines (and rewrites it to be clearer) do_mmap(), which sadly\nduplicates it in mm/mmap.c and mm/nommu.c.

These IPIs are useful and cannot be avoided\naltogether, but in certain cases it is possible to interrupt only specific\nCPUs that have useful work to do and not the entire system.\n\nThis patch set, inspired by discussions with Peter Zijlstra and Frederic\nWeisbecker when testing the nohz task patch set, is a first stab at trying\nto explore doing this by locating the places where such global IPI calls\nare being made and turning the global IPI into an IPI for a specific group\nof CPUs. The purpose of the patch set is to get feedback if this is the\nright way to go for dealing with this issue and indeed, if the issue is\neven worth dealing with at all. Based on the feedback from this patch set\nI plan to offer further patches that address similar issue in other code\npaths.\n\nThis patch creates an on_each_cpu_mask() and on_each_cpu_cond()\ninfrastructure API (the former derived from existing arch specific\nversions in Tile and Arm) and uses them to turn several global IPI\ninvocation to per CPU group invocations.\n\nCore kernel:\n\non_each_cpu_mask() calls a function on processors specified by cpumask,\nwhich may or may not include the local processor.\n\nYou must not call this function with disabled interrupts or from a\nhardware interrupt handler or from a bottom half handler.\n\narch/arm:\n\nNote that the generic version is a little different then the Arm one:\n\n1. It has the mask as first parameter\n2. It calls the function on the calling CPU with interrupts disabled,\n but this should be OK since the function is called on the other CPUs\n with interrupts disabled anyway.\n\narch/tile:\n\nThe API is the same as the tile private one, but the generic version\nalso calls the function on the with interrupts disabled in UP case\n\nThis is OK since the function is called on the other CPUs\nwith interrupts disabled.\n\nSigned-off-by: Gilad Ben-Yossef \u003cgilad@benyossef.com\u003e\nReviewed-by: Christoph Lameter \u003ccl@linux.com\u003e\nAcked-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Russell King \u003clinux@arm.linux.org.uk\u003e\nCc: Pekka Enberg \u003cpenberg@kernel.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Sasha Levin \u003clevinsasha928@gmail.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Alexander Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nAcked-by: Michal Nazarewicz \u003cmina86@mina86.org\u003e\nCc: Kosaki Motohiro \u003ckosaki.motohiro@gmail.com\u003e\nCc: Milton Miller \u003cmiltonm@bga.com\u003e\nCc: Russell King \u003clinux@arm.linux.org.uk\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0195c00244dc2e9f522475868fa278c473ba7339", "tree": "f97ca98ae64ede2c33ad3de05ed7bbfa4f4495ed", "parents": [ "f21ce8f8447c8be8847dadcfdbcc76b0d7365fa5", "141124c02059eee9dbc5c86ea797b1ca888e77f7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 15:58:21 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 15:58:21 2012 -0700" }, "message": "Merge tag \u0027split-asm_system_h-for-linus-20120328\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system\n\nPull \"Disintegrate and delete asm/system.h\" from David Howells:\n \"Here are a bunch of patches to disintegrate asm/system.h into a set of\n separate bits to relieve the problem of circular inclusion\n dependencies.\n\n I\u0027ve built all the working defconfigs from all the arches that I can\n and made sure that they don\u0027t break.\n\n The reason for these patches is that I recently encountered a circular\n dependency problem that came about when I produced some patches to\n optimise get_order() by rewriting it to use ilog2().\n\n This uses bitops - and on the SH arch asm/bitops.h drags in\n asm-generic/get_order.h by a circuituous route involving asm/system.h.\n\n The main difficulty seems to be asm/system.h. It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

There are already a number of filter flags in\n/proc/\u003cpid\u003e/coredump_filter, however, these allow one to specify \u0027types\u0027\nof kernel memory, not specific address ranges (which is needed in this\ncase).\n\nSince there are no more vma flags available, the first patch eliminates\nthe need for the \u0027VM_ALWAYSDUMP\u0027 flag. The flag is used internally by\nthe kernel to mark vdso and vsyscall pages. However, it is simple\nenough to check if a vma covers a vdso or vsyscall page without the need\nfor this flag.\n\nThe second patch then replaces the \u0027VM_ALWAYSDUMP\u0027 flag with a new\n\u0027VM_NODUMP\u0027 flag, which can be set by userspace using new madvise flags:\n\u0027MADV_DONTDUMP\u0027, and unset via \u0027MADV_DODUMP\u0027. The core dump filters\ncontinue to work the same as before unless \u0027MADV_DONTDUMP\u0027 is set on the\nregion.\n\nThe qemu code which implements this features is at:\n\n http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch\n\nIn my testing the qemu core dump shrunk from 383MB -\u003e 13MB with this\npatch.\n\nI also believe that the \u0027MADV_DONTDUMP\u0027 flag might be useful for\nsecurity sensitive apps, which might want to select which areas are\ndumped.\n\nThis patch:\n\nThe VM_ALWAYSDUMP flag is currently used by the coredump code to\nindicate that a vma is part of a vsyscall or vdso section. However, we\ncan determine if a vma is in one these sections by checking it against\nthe gate_vma and checking for a non-NULL return value from\narch_vma_name().

APIs, architectures will generally want to\nbe able to make direct syscalls to msgsnd(), shmctl(), etc., and\nin the kernel we would want them to be handled directly by\ncompat_sys_xxx() functions, as is true for other compat syscalls.\n\nHowever, for historical reasons, several of the existing compat IPC\nsyscalls do not do this. semctl() expects a pointer to the fourth\nargument, instead of the fourth argument itself. msgsnd(), msgrcv()\nand shmat() expect arguments in different order.\n\nThis change adds an ARCH_WANT_OLD_COMPAT_IPC config option that can be\nset to preserve this behavior for ports that use it (x86, sparc, powerpc,\ns390, and mips). No actual semantics are changed for those architectures,\nand there is only a minimal amount of code refactoring in ipc/compat.c.\n\nNewer architectures like tile (and perhaps future architectures such\nas arm64 and unicore64) should not select this option, and thus can\navoid having any IPC-specific code at all in their architecture-specific\ncompat layer. In the same vein, if this option is not selected, IPC_64\nmode is assumed, since that\u0027s what the \u003casm-generic\u003e headers expect.\n\nThe workaround code in \"tile\" for msgsnd() and msgrcv() is removed\nwith this change; it also fixes the bug that shmat() and semctl() were\nnot being properly handled.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "ce06b0f5500fd70cfa1a1d9cdc22747abe404267", "tree": "f3a320b31308c409539dba1b454babb0c38328e4", "parents": [ "ad092338350e517608a41341095b6b1e312c4eb1" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Wed Mar 14 14:33:16 2012 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Wed Mar 14 14:33:16 2012 -0400" }, "message": "arch/tile/configs: convert to minimal configs via \"make savedefconfig\"\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "ad092338350e517608a41341095b6b1e312c4eb1", "tree": "1f2d5273f4e7fc3648f571355bfb7f1f79d796b7", "parents": [ "cf8c1dafe19ae9f855bf7b9cce2e13b26c3289b7" ], "author": { "name": "Matt Fleming", "email": "matt.fleming@intel.com", "time": "Tue Feb 14 11:41:06 2012 +0000" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Tue Mar 13 16:42:05 2012 -0400" }, "message": "tile: Use set_current_blocked() and block_sigmask()\n\nAs described in e6fa16ab (\"signal: sigprocmask() should do\nretarget_shared_pending()\") the modification of current-\u003eblocked is\nincorrect as we need to check whether the signal we\u0027re about to block\nis pending in the shared queue.\n\nAlso, use the new helper function introduced in commit 5e6292c0f28f\n(\"signal: add block_sigmask() for adding sigmask to current-\u003eblocked\")\nwhich centralises the code for updating current-\u003eblocked after\nsuccessfully delivering a signal and reduces the amount of duplicate\ncode across architectures.

The whole guarantees\nthat we only update the dyntick mode on irq exit if we actually\ninterrupted the dyntick idle mode, and that we enter in RCU extended\nquiescent state from idle loop entry only.\n\nSplit this function into:\n\n- tick_nohz_idle_enter(), which sets ts-\u003einidle to 1, enters\ndynticks idle mode unconditionally if it can, and enters into RCU\nextended quiescent state.\n\n- tick_nohz_irq_exit() which only updates the dynticks idle mode\nwhen ts-\u003einidle is set (ie: if tick_nohz_idle_enter() has been called).\n\nTo maintain symmetry, tick_nohz_restart_sched_tick() has been renamed\ninto tick_nohz_idle_exit().\n\nThis simplifies the code and micro-optimize the irq exit path (no need\nfor local_irq_save there). This also prepares for the split between\ndynticks and rcu extended quiescent state logics. We\u0027ll need this split to\nfurther fix illegal uses of RCU in extended quiescent states in the idle\nloop.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Frysinger \u003cvapier@gentoo.org\u003e\nCc: Guan Xuetao \u003cgxt@mprc.pku.edu.cn\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nCc: Hans-Christian Egtvedt \u003chans-christian.egtvedt@atmel.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Paul E.
