Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "4365a5676fa3aa1d5ae6c90c22a0044f09ba584e", "tree": "5b9914ccbdcf2aa695473421e71f6299fbe78cef", "parents": [ "3b4798cbc13dd8d1150aa6377f97f0e11450a67d" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hioryu@jp.fujitsu.com", "time": "Tue Dec 15 16:45:33 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 16 07:19:57 2009 -0800" }, "message": "oom-kill: fix NUMA constraint check with nodemask\n\nFix node-oriented allocation handling in oom-kill.c I myself think of this\nas a bugfix not as an ehnancement.\n\nIn these days, things are changed as\n - alloc_pages() eats nodemask as its arguments, __alloc_pages_nodemask().\n - mempolicy don\u0027t maintain its own private zonelists.\n (And cpuset doesn\u0027t use nodemask for __alloc_pages_nodemask())\n\nSo, current oom-killer\u0027s check function is wrong.\n\nThis patch does\n - check nodemask, if nodemask \u0026\u0026 nodemask doesn\u0027t cover all\n node_states[N_HIGH_MEMORY], this is CONSTRAINT_MEMORY_POLICY.\n - Scan all zonelist under nodemask, if it hits cpuset\u0027s wall\n this faiulre is from cpuset.\nAnd\n - modifies the caller of out_of_memory not to call oom if __GFP_THISNODE.\n This doesn\u0027t change \"current\" behavior.

So in cases with CONFIG_KEXEC, where\ncrash_kexec() was directly called from sysrq-c before, now it can be said\nthat a step of \"real oops\" was inserted before starting kdump.\n\nHowever, in contrast to oops via SysRq-c from keyboard which results in\npanic due to in_interrupt(), oops via \"echo c \u003e /proc/sysrq-trigger\" will\nnot become panic unless panic_on_oops\u003d1. It means that even if dump is\nproperly configured to be taken on panic, the sysrq-c from proc interface\nmight not start crashdump while the sysrq-c from keyboard can start\ncrashdump. This confuses traditional users of kdump, i.e. people who\nexpect sysrq-c to do common behavior in both of the keyboard and proc\ninterface.\n\nThis patch brings the keyboard and proc interface behavior of sysrq-c in\nline, by forcing panic_on_oops\u003d1 before oops in sysrq-c handler.\n\nAnd some updates in documentation are included, to clarify that there is\nno longer dependency with CONFIG_KEXEC, and that now the system can just\ncrash by sysrq-c if no dump mechanism is configured.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nCc: Ken\u0027ichi Ohmichi \u003coomichi@mxs.nes.nec.co.jp\u003e\nAcked-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: Brayan Arraes \u003cbrayan@yack.com.br\u003e\nCc: Eric W.

If CONFIG_KEXEC is configured, it calls crash_kexec\ndirectly, which implies that the kexec kernel will either be booted (if\nits been previously loaded), or it will simply do nothing (the no kexec\nkernel has been loaded).\n\nIt would be much easier to just simplify the whole thing to dereference a\nNULL pointer all the time regardless of configuration.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.

The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "b2e9c7d07fcc8966d6aa50a77afa66c9919bd5a8", "tree": "55ef4fd8db585802ac2f0185d5da36ab041b05b5", "parents": [ "74ae3221818eaf3884ceac931ba3cd2c00045483" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Sat Sep 30 23:28:02 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:24 2006 -0700" }, "message": "[PATCH] sysrq: disable lockdep on reboot\n\nSysRq : Emergency Sync\nEmergency Sync complete\nSysRq : Emergency Remount R/O\nEmergency Remount complete\nSysRq : Resetting\nBUG: warning at kernel/lockdep.c:1816/trace_hardirqs_on() (Not tainted)\n\nCall Trace:\n [\u003cffffffff8026d56d\u003e] show_trace+0xae/0x319\n [\u003cffffffff8026d7ed\u003e] dump_stack+0x15/0x17\n [\u003cffffffff802a68d1\u003e] trace_hardirqs_on+0xbc/0x13d\n [\u003cffffffff803a8eec\u003e] sysrq_handle_reboot+0x9/0x11\n [\u003cffffffff803a8f8d\u003e] __handle_sysrq+0x99/0x130\n [\u003cffffffff803a903b\u003e] handle_sysrq+0x17/0x19\n [\u003cffffffff803a36ee\u003e] kbd_event+0x32e/0x57d\n [\u003cffffffff80401e35\u003e] input_event+0x42d/0x45b\n [\u003cffffffff804063eb\u003e] atkbd_interrupt+0x44d/0x53d\n [\u003cffffffff803fe5c5\u003e] serio_interrupt+0x49/0x86\n [\u003cffffffff803ff2a4\u003e] i8042_interrupt+0x202/0x21a\n [\u003cffffffff80210cf0\u003e] handle_IRQ_event+0x2c/0x64\n [\u003cffffffff802bfd8b\u003e] __do_IRQ+0xaf/0x114\n [\u003cffffffff8026ea24\u003e] do_IRQ+0xf8/0x107\n [\u003cffffffff8025f886\u003e] ret_from_intr+0x0/0xf\nDWARF2 unwinder stuck at ret_from_intr+0x0/0xf\nLeftover inexact backtrace:\n \u003cIRQ\u003e \u003cEOI\u003e [\u003cffffffff80258e36\u003e] mwait_idle+0x3f/0x54\n [\u003cffffffff8024a33a\u003e] cpu_idle+0xa2/0xc5\n [\u003cffffffff8026c34e\u003e] rest_init+0x2b/0x2d\n [\u003cffffffff809708bc\u003e] start_kernel+0x24a/0x24c\n [\u003cffffffff8097028b\u003e] _sinittext+0x28b/0x292\n\nSince we\u0027re shutting down anyway, don\u0027t bother being smart,\njust turn the thing off.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f400e198b2ed26ce55b22a1412ded0896e7516ac", "tree": "a3d78bfc1c20635e199fe0fe85aaa1d8792acc58", "parents": [ "959ed340f4867fda7684340625f60e211c2296d6" ], "author": { "name": "Sukadev Bhattiprolu", "email": "sukadev@us.ibm.com", "time": "Fri Sep 29 02:00:07 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:12 2006 -0700" }, "message": "[PATCH] pidspace: is_init()\n\nThis is an updated version of Eric Biederman\u0027s is_init() patch.\n(http://lkml.org/lkml/2006/2/6/280).
