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

These tools ask\nfor the number of online cpus with sysconf(_SC_NPROCESSORS_ONLN)\nand then try to create events for cpus 0, 1, ..., N-1.\n\nThis creates problems for systems where the online cpus are\nnumbered sparsely. For example, a POWER6 system in\nsingle-threaded mode (i.e. only running 1 hardware thread per\ncore) will have only even-numbered cpus online.\n\nThis fixes the problem by reading the /sys/devices/system/cpu/online\nfile to find out which cpus are online. The code that does that is in\ntools/perf/util/cpumap.[ch], and consists of a read_cpu_map()\nfunction that sets up a cpumap[] array and returns the number of\nonline cpus.

"message": "perf lock: Drop the buffers multiplexing dependency\n\nWe need to deal with time ordered events to build a correct\nstate machine of lock events. This is why we multiplex the lock\nevents buffers. But the ordering is done from the kernel, on\nthe tracing fast path, leading to high contention between cpus.\n\nWithout multiplexing, the events appears in a weak order.\nIf we have four events, each split per cpu, perf record will\nread the events buffers in the following order:\n\n[ CPU0 ev0, CPU0 ev1, CPU0 ev3, CPU0 ev4, CPU1 ev0, CPU1 ev0....]\n\nTo handle a post processing reordering, we could just read and sort\nthe whole in memory, but it just doesn\u0027t scale with high amounts\nof events: lock events can fill huge amounts in few times.\n\nBasically we need to sort in memory and find a \"grace period\"\npoint when we know that a given slice of previously sorted events\ncan be committed for post-processing, so that we can unload the\nmemory usage step by step and keep a scalable sorting list.\n\nThere is no strong rules about how to define such \"grace period\".\nWhat does this patch is:\n\nWe define a FLUSH_PERIOD value that defines a grace period in\nseconds.\nWe want to have a slice of events covering 2 * FLUSH_PERIOD in our\nsorted list.\nIf FLUSH_PERIOD is big enough, it ensures every events that occured\nin the first half of the timeslice have all been buffered and there\nare none remaining and there won\u0027t be further to put inside this\nfirst timeslice. Then once we reach the 2 * FLUSH_PERIOD\ntimeslice, we flush the first half to be gentle with the memory\n(the second half can still get new events in the middle, so wait\nanother period to flush it)\n\nFLUSH_PERIOD is defined to 5 seconds. Say the first event started on\ntime t0. We can safely assume that at the time we are processing\nevents of t0 + 10 seconds, ther won\u0027t be anymore events to read\nfrom perf.data that occured between t0 and t0 + 5 seconds. Hence\nwe can safely flush the first half.\n\nTo point out funky bugs, we have a guardian that checks a new event\ntimestamp is not below the last event\u0027s timestamp flushed and that\ndisplays a warning in this case.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nCc: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "84c6f88fc8265d7a712d7d6ed8fc1a878dfc84d1", "tree": "4f5b0cf3357b2afbc41fa257e524d62b04cd392e", "parents": [ "44ee63587dce85593c22497140db16f4e5027860" ], "author": { "name": "Hitoshi Mitake", "email": "mitake@dcl.info.waseda.ac.jp", "time": "Thu Feb 04 16:08:15 2010 +0900" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sat Feb 27 17:05:22 2010 +0100" }, "message": "perf lock: Fix and add misc documentally things\n\nI\u0027ve forgot to add \u0027perf lock\u0027 line to command-list.txt,\nso users of perf could not find perf lock when they type \u0027perf\u0027.\n\nFixing command-list.txt requires document\n(tools/perf/Documentation/perf-lock.txt).\nBut perf lock is too much \"under construction\" to write a\nstable document, so this is something like pseudo document for now.\n\nAnd I wrote description of perf lock at help section of\nCONFIG_LOCK_STAT, this will navigate users of lock trace events.\n\nSigned-off-by: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nLKML-Reference: \u003c1265267295-8388-1-git-send-email-mitake@dcl.info.waseda.ac.jp\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\n" }, { "commit": "018cbffe6819f6f8db20a0a3acd9bab9bfd667e4", "tree": "fadde2521591998dc653fa094c636e8a547e620d", "parents": [ "1dd2980d990068e20045b90c424518cc7f3657ff", "60b341b778cc2929df16c0a504c91621b3c6a4ad" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sat Feb 27 16:18:46 2010 +0100" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sat Feb 27 16:18:46 2010 +0100" }, "message": "Merge commit \u0027v2.6.33\u0027 into perf/core\n\nMerge reason:\n\t__percpu annotations need the corresponding sparse address\nspace definition upstream.\n\nConflicts:\n\ttools/perf/util/probe-event.c (trivial)\n" }, { "commit": "4385d580f2278abab6d336e52522e9a6f5452a11", "tree": "ab35d78343741a1130b779cd1d98f5ac0041ac37", "parents": [ "f22f54f4491acd987a6c5a92de52b60ca8b58b61" ], "author": { "name": "David S.

Cast Dwarf_Addr to uintmax_t for printf-formats.\n\nChanges in v2:\n - Cast Dwarf_Addr to unsigned long long for printf-formats.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133611.6725.45078.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5c8d1cbbbed39dcab2ecf429d6e56ea548c0fda4", "tree": "8ce3346a689e6f4744b2a48e1178f40560137ca6", "parents": [ "161a26b0c231b5d2e60e9c132fa360cd9dac4720" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:36:04 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:30 2010 +0100" }, "message": "perf probe: Show more lines after last line\n\nShow 2 more lines after the last probe-able line.\nThis will clearly show the last closed-brace of\ninline functions.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133604.6725.76820.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "161a26b0c231b5d2e60e9c132fa360cd9dac4720", "tree": "65890fa84d614d04ded92b4214f0e76a46b90461", "parents": [ "e92b85e1ffaa0bd8e5d92e7c378a3909e7f23122" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:35:57 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:29 2010 +0100" }, "message": "perf probe: Check function address range strictly in line finder\n\nCheck (inlined) function address range strictly for\nimproving output of probe-able lines of inline functions.\n\nWithout this change, perf probe --line \u003cfunction\u003e sometimes\nshowed other inline function bodies too, because it didn\u0027t\nfilter out inlined functions.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133557.6725.20697.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e92b85e1ffaa0bd8e5d92e7c378a3909e7f23122", "tree": "6bd934ca363a3529ad4ecb1112c1d2c70c13089b", "parents": [ "804b36068eccd8163ccea420c662fb5d1a21b141" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:35:50 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:29 2010 +0100" }, "message": "perf probe: Use libdw callback routines\n\nUse libdw callback functions aggressively, and remove\nlocal tree-search API.

file,\nevents, etc, so I untied these layers.\n\nThis reduces the complexity for the users as the number of\nparameters to most of the symbols and session APIs now was\nreduced while not adding more
