So the other\nNMI users such as kgdb simply have no chance to get NMI\non their hands.\n\nSide note: at moment there is no way to run nmi-watchdog\ntogether with perf tool. This is because both \u0027perf top\u0027 and\nnmi-watchdog use same event. So while nmi-watchdog reserves\none event/counter for own needs there is no room for perf tool\nleft (there is a way to disable nmi-watchdog on boot of course).\n\nMing has tested this patch with the following results\n\n | 1. watchdog disabled\n |\n | kgdb tests on boot OK\n | perf works OK\n |\n | 2. watchdog enabled, without patch perf-x86-p4-nmi-4\n |\n | kgdb tests on boot hang\n |\n | 3. watchdog enabled, without patch perf-x86-p4-nmi-4 and do not run kgdb\n | tests on boot\n |\n | \"perf top\" partialy works\n | cpu-cycles no\n | instructions yes\n | cache-references no\n | cache-misses no\n | branch-instructions no\n | branch-misses yes\n | bus-cycles no\n |\n | 4. watchdog enabled, with patch perf-x86-p4-nmi-4 applied\n |\n | kgdb tests on boot OK\n | perf does not work, NMI \"Dazed and confused\" messages show up\n |\n\nWhich means we still have problems with p4 box due to \u0027unknown\u0027\nnmi happens but at least it should fix kgdb test cases.\n\nReported-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nReported-by: Don Zickus \u003cdzickus@redhat.com\u003e\nSigned-off-by: Cyrill Gorcunov \u003cgorcunov@openvz.org\u003e\nAcked-by: Don Zickus \u003cdzickus@redhat.com\u003e\nAcked-by: Lin Ming \u003cming.m.lin@intel.com\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLKML-Reference: \u003c4D275E7E.3040903@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2d75af2f2a7a6103a6d539a492fe81deacabde44", "tree": "283f6f7acc28936e25656502e77e10909fde7d6f", "parents": [ "870915e047a2da695be118d32dd5a900f0c3e933" ], "author": { "name": "Jason Baron", "email": "jbaron@redhat.com", "time": "Fri Jan 07 13:36:58 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Fri Jan 07 23:36:59 2011 -0500" }, "message": "dynamic debug: Fix build issue with older gcc\n\nOn older gcc (3.3) dynamic debug fails to compile:\n\ninclude/net/inet_connection_sock.h: In function `inet_csk_reset_xmit_timer\u0027:\ninclude/net/inet_connection_sock.h:236: error: duplicate label declaration `do_printk\u0027\ninclude/net/inet_connection_sock.h:219: error: this is a previous declaration\ninclude/net/inet_connection_sock.h:236: error: duplicate label declaration `out\u0027\ninclude/net/inet_connection_sock.h:219: error: this is a previous declaration\ninclude/net/inet_connection_sock.h:236: error: duplicate label `do_printk\u0027\ninclude/net/inet_connection_sock.h:236: error: duplicate label `out\u0027\n\nFix, by reverting the usage of JUMP_LABEL() in dynamic debug for now.\n\nCc: \u003cstable@kernel.org\u003e\nReported-by: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nTested-by: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "870915e047a2da695be118d32dd5a900f0c3e933", "tree": "5d816db36d55d7b78b58dbb1d60a127d528ebb06", "parents": [ "1dbd1951f39e13da579ffe879cce19586d0462de" ], "author": { "name": "Mathieu Desnoyers", "email": "mathieu.desnoyers@efficios.com", "time": "Thu Oct 28 11:31:17 2010 -0400" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Fri Jan 07 23:26:29 2011 -0500" }, "message": "tracing: Fix TRACE_EVENT power tracepoint creation\n\nDEFINE_TRACE should also exist when CONFIG_EVENT_TRACING\u003dn.

reorganization\n\nMove \u0027main\u0027 code vs. subroutines around so that they are not so\nintermixed, for better readability/understanding (relative to Perl).\nIt was messy to follow the primary flow of code execution with the\ncode being mixed. Now the code begins with data initialization,\nfollowed by all subroutines, then ends with the main code execution.\n\nThis is almost totally source code movement, with a few changes as\nneeded for forward declarations.\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d5ba92b7958e3ff2f0878e45b9b42cb6976853dd", "tree": "b5bfd9114578ff4acfd03fa63c907ae38f4a6752", "parents": [ "a40649781b9c10e192fad9f00a60c6d946da553f" ], "author": { "name": "Nicolas Kaiser", "email": "nikai@nikai.net", "time": "Wed Jan 05 16:27:53 2011 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 06 09:59:38 2011 -0800" }, "message": "Documentation: update kernel-docs.txt\n\nFixed typos, and removed duplicated entries.\n\nSigned-off-by: Nicolas Kaiser \u003cnikai@nikai.net\u003e\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a40649781b9c10e192fad9f00a60c6d946da553f", "tree": "07e802f84415b5352dc238185b7b13268d62c7e4", "parents": [ "3c0eee3fe6a3a1c745379547c7e7c904aa64f6d5" ], "author": { "name": "Michael Prokop", "email": "mika@grml.org", "time": "Wed Jan 05 16:27:15 2011 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 06 09:59:37 2011 -0800" }, "message": "Documentation/dontdiff: add further autogenerated files to ignore list\n\nMainly resulting from (but not limited to) autogenerated files of\nlib/raid6 and drivers/gpu/drm/radeon.

This is desirable behavior, but, as a side effect,\nthe commit leads to an oops when atl1_set_ringparam() attempts to alter\nthe number of rx or tx elements in the ring buffer (by using ethtool\n-G, for example). We don\u0027t want SMB or CMB to change during this\noperation.\n\nModify atl1_set_ringparam() to preserve SMB and CMB when changing ring\nparameters.\n\nCc: stable@kernel.org\nSigned-off-by: Jay Cliburn \u003cjcliburn@gmail.com\u003e\nReported-by: Tõnu Raitviir \u003cjussuf@linux.ee\u003e\nSigned-off-by: David S.
