However, these inherited\ncounters have a unique identifier so that events like\nPERF_EVENT_PERIOD and PERF_EVENT_THROTTLE can be specific about which\ncounter gets modified, which is important when trying to normalize the\nsample streams.\n\nThis patch removes PERF_EVENT_PERIOD in favour of PERF_SAMPLE_PERIOD,\nwhich is more useful anyway, since changing periods became a lot more\ncommon than initially thought -- rendering PERF_EVENT_PERIOD the less\nuseful solution (also, PERF_SAMPLE_PERIOD reports the more accurate\nvalue, since it reports the value used to trigger the overflow,\nwhereas PERF_EVENT_PERIOD simply reports the requested period changed,\nwhich might only take effect on the next cycle).\n\nThis still leaves us PERF_EVENT_THROTTLE to consider, but since that\n_should_ be a rare occurrence, and linking it to a primary id is the\nmost useful bit to diagnose the problem, we introduce a\nPERF_SAMPLE_STREAM_ID, for those few cases where the full\nreconstruction is important.\n\n[Does change the ABI a little, but I see no other way out]\n\nSuggested-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c1248095846.15751.8781.camel@twins\u003e\n"

      "message": "x86: atomic64: Code atomic(64)_read and atomic(64)_set in C not CPP\n\nOccasionally we get bugs where atomic_read or atomic_set are\nused on atomic64_t variables or vice versa.  These bugs don\u0027t\ngenerate warnings on x86 because atomic_read and atomic_set are\ncoded as macros rather than C functions, so we don\u0027t get any\ntype-checking on their arguments; similarly for atomic64_read\nand atomic64_set in 64-bit kernels.\n\nThis converts them to C functions so that the arguments are\ntype-checked and bugs like this will get caught more easily. It\nalso converts atomic_cmpxchg and atomic_xchg, and\natomic64_cmpxchg and atomic64_xchg on 64-bit, so we get\ntype-checking on their arguments too.\n\nCompiling a typical 64-bit x86 config, this generates no new\nwarnings, and the vmlinux text is 86 bytes smaller.\n\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nLKML-Reference: \u003calpine.LFD.2.01.0907021653030.3210@localhost.localdomain\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

Otherwise \"l1-data\"\nwould match the \"l1-d\" alias and the \"ata\" would not be\nconsumed.\n\nThis allows event modifiers indicating what processor modes to\ncount in to be applied to any event, not just numeric events,\nand adds a \":h\" modifier to indicate counting in hypervisor\nmode.  Specifying \":u\" now sets both exclude_kernel and\nexclude_hv, and so on.  Multiple modes can be specified, e.g.\n\":uk\" will count in user or hypervisor mode (i.e. only\nexclude_kernel will be set).\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLKML-Reference: \u003c19018.53826.843815.189847@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
