Interrupts\nshould be hard-disabled at this point but they were enabled. Because\nthe interrupt was not recoverable the system panicked.\n\nThe reason is that the exception exit path was calling\nperf_event_do_pending after hard-disabling interrupts, and\nperf_event_do_pending will re-enable interrupts.\n\nThe simplest and cleanest fix for this is to use the same mechanism\nthat 32-bit powerpc does, namely to cause a self-IPI by setting the\ndecrementer to 1. This means we can remove the tests in the exception\nexit path and raw_local_irq_restore.\n\nThis also makes sure that the call to perf_event_do_pending from\ntimer_interrupt() happens within irq_enter/irq_exit. (Note that\ncalling perf_event_do_pending from timer_interrupt does not mean that\nthere is a possible 1/HZ latency; setting the decrementer to 1 ensures\nthat the timer interrupt will happen immediately, i.e. within one\ntimebase tick, which is a few nanoseconds or 10s of nanoseconds.)\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: stable@kernel.org\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "8e6d5573af55435160d329f6ae3fe16a0abbdaec", "tree": "30156432a5589fbb602bbe22e31c9e48aec9c476", "parents": [ "96c21a460a37880abfbc8445d5b098dbab958a29" ], "author": { "name": "Lin Ming", "email": "ming.m.lin@intel.com", "time": "Sat May 08 20:28:41 2010 +1000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue May 11 17:08:24 2010 +0200" }, "message": "perf, powerpc: Implement group scheduling transactional APIs\n\n[paulus@samba.org: Set cpuhw-\u003eevent[i]-\u003ehw.config in\npower_pmu_commit_txn.]\n\nSigned-off-by: Lin Ming \u003cming.m.lin@intel.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c20100508102841.GA10650@brick.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "b8b14c66765ccba884c5c4570bf8be361d211d95", "tree": "2891c2ee4396a5f3939a705cc720dcb3518a7afb", "parents": [ "66f41d4c5c8a5deed66fdcc84509376c9a0bf9d8" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Mon May 03 07:36:22 2010 -0500" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Tue May 04 01:27:18 2010 -0500" }, "message": "powerpc/swiotlb: Fix off by one in determining boundary of which ops to use\n\nWhen we compare the devices DMA mask to the amount of memory we need to\nmake sure we treat the DMA mask as an address boundary.

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": "6fa41366c1c5e8b9640baba22d2b90ec9035a889", "tree": "ad3b2214e0c5d4774f200ab7bb08b832babb9468", "parents": [ "309d1dcb5b73ab1f8212aff3037a7bcb46afe819", "9eff26ea48bfbe2885b158742a7512a097ec911b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 26 15:09:33 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 26 15:09:33 2010 -0700" }, "message": "Merge branch \u0027perf-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027perf-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n powerpc/perf_events: Fix call-graph recording, add perf_arch_fetch_caller_regs\n perf top: Add missing initialization to zero\n perf probe: Use original address instead of CU-based address\n perf probe: Fix offset to allow signed value\n perf top: Improve the autosizing of column lenghts\n perf probe: Fix need_dwarf flag if lazy matching is used\n perf probe: Fix probe_point buffer overrun\n" }, { "commit": "95c46afe6034d15bdf0f95d69f25489cecad9a47", "tree": "a3bff5de25890f6de94cbf431bb0f94073893507", "parents": [ "cf3966bf6ecfe25a75d625771e327b84878bc09d", "191aee58b6568cf8143901bfa3f57a9b8faa6f1c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 19 13:42:43 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 19 13:42:43 2010 -0700" }, "message": "Merge branch \u0027merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc\n\n* \u0027merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:\n powerpc: Remove IOMMU_VMERGE config option\n powerpc: Fix swiotlb to respect the boot option\n powerpc: Do not call prink when CONFIG_PRINTK is not defined\n powerpc: Use correct ccr bit for syscall error status\n powerpc/fsl-booke: Get coherent bit from PTE\n powerpc/85xx: Make sure lwarx hint isn\u0027t set on ppc32\n" }, { "commit": "191aee58b6568cf8143901bfa3f57a9b8faa6f1c", "tree": "296e0a4815c59e0289d88cbec8bfe6d02b50bb85", "parents": [ "a93272969c6b1d59883fcbb04845420bd72c9a20" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Tue Mar 02 14:25:38 2010 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Mar 19 16:38:16 2010 +1100" }, "message": "powerpc: Remove IOMMU_VMERGE config option\n\nThe description says:\n\n Cause IO segments sent to a device for DMA to be merged virtually\n by the IOMMU when they happen to have been allocated contiguously.\n This doesn\u0027t add pressure to the IOMMU allocator.
