      "message": "ftrace: Fix dynamic selftest failure on some archs\n\nArchs that do not implement CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST, will\nfail the dynamic ftrace selftest.\n\nThe function tracer has a quick \u0027off\u0027 variable that will prevent\nthe call back functions from being called. This variable is called\nfunction_trace_stop. In x86, this is implemented directly in the mcount\nassembly, but for other archs, an intermediate function is used called\nftrace_test_stop_func().\n\nIn dynamic ftrace, the function pointer variable ftrace_trace_function is\nused to update the caller code in the mcount caller. But for archs that\ndo not have CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST set, it only calls\nftrace_test_stop_func() instead, which in turn calls __ftrace_trace_function.\n\nWhen more than one ftrace_ops is registered, the function it calls is\nftrace_ops_list_func(), which will iterate over all registered ftrace_ops\nand call the callbacks that have their hash matching.\n\nThe issue happens when two ftrace_ops are registered for different functions\nand one is then unregistered. The __ftrace_trace_function is then pointed\nto the remaining ftrace_ops callback function directly. This mean it will\nbe called for all functions that were registered to trace by both ftrace_ops\nthat were registered.\n\nThis is not an issue for archs with CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST,\nbecause the update of ftrace_trace_function doesn\u0027t happen until after all\nfunctions have been updated, and then the mcount caller is updated. But\nfor those archs that do use the ftrace_test_stop_func(), the update is\nimmediate.\n\nThe dynamic selftest fails because it hits this situation, and the\nftrace_ops that it registers fails to only trace what it was suppose to\nand instead traces all other functions.\n\nThe solution is to delay the setting of __ftrace_trace_function until\nafter all the functions have been updated according to the registered\nftrace_ops. Also, function_trace_stop is set during the update to prevent\nfunction tracing from calling code that is caused by the function tracer\nitself.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "x86: Don\u0027t use frame pointer to save old stack on irq entry\n\nrbp is used in SAVE_ARGS_IRQ to save the old stack pointer\nin order to restore it later in ret_from_intr.\n\nIt is convenient because we save its value in the irq regs\nand it\u0027s easily restored using the leave instruction.\n\nHowever this is a kind of abuse of the frame pointer which\nrole is to help unwinding the kernel by chaining frames\ntogether, each node following the return address to the\nprevious frame.\n\nBut although we are breaking the frame by changing the stack\npointer, there is no preceding return address before the new\nframe. Hence using the frame pointer to link the two stacks\nbreaks the stack unwinders that find a random value instead of\na return address here.\n\nThere is no workaround that can work in every case. We are using\nthe fixup_bp_irq_link() function to dereference that abused frame\npointer in the case of non nesting interrupt (which means stack\nchanged).\nBut that doesn\u0027t fix the case of interrupts that don\u0027t change the\nstack (but we still have the unconditional frame link), which is\nthe case of hardirq interrupting softirq. We have no way to detect\nthis transition so the frame irq link is considered as a real frame\npointer and the return address is dereferenced but it is still a\nspurious one.\n\nThere are two possible results of this: either the spurious return\naddress, a random stack value, luckily belongs to the kernel text\nand then the unwinding can continue and we just have a weird entry\nin the stack trace. Or it doesn\u0027t belong to the kernel text and\nunwinding stops there.\n\nThis is the reason why stacktraces (including perf callchains) on\nirqs that interrupted softirqs don\u0027t work very well.\n\nTo solve this, we don\u0027t save the old stack pointer on rbp anymore\nbut we save it to a scratch register that we push on the new\nstack and that we pop back later on irq return.\n\nThis preserves the whole frame chain without spurious return addresses\nin the middle and drops the need for the horrid fixup_bp_irq_link()\nworkaround.\n\nAnd finally irqs that interrupt softirq are sanely unwinded.\n\nBefore:\n\n    99.81%         perf  [kernel.kallsyms]  [k] perf_pending_event\n                   |\n                   --- perf_pending_event\n                       irq_work_run\n                       smp_irq_work_interrupt\n                       irq_work_interrupt\n                      |\n                      |--41.60%-- __read\n                      |          |\n                      |          |--99.90%-- create_worker\n                      |          |          bench_sched_messaging\n                      |          |          cmd_bench\n                      |          |          run_builtin\n                      |          |          main\n                      |          |          __libc_start_main\n                      |           --0.10%-- [...]\n\nAfter:\n\n     1.64%  swapper  [kernel.kallsyms]  [k] perf_pending_event\n            |\n            --- perf_pending_event\n                irq_work_run\n                smp_irq_work_interrupt\n                irq_work_interrupt\n               |\n               |--95.00%-- arch_irq_work_raise\n               |          irq_work_queue\n               |          __perf_event_overflow\n               |          perf_swevent_overflow\n               |          perf_swevent_event\n               |          perf_tp_event\n               |          perf_trace_softirq\n               |          __do_softirq\n               |          call_softirq\n               |          do_softirq\n               |          irq_exit\n               |          |\n               |          |--73.68%-- smp_apic_timer_interrupt\n               |          |          apic_timer_interrupt\n               |          |          |\n               |          |          |--96.43%-- amd_e400_idle\n               |          |          |          cpu_idle\n               |          |          |          start_secondary\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: H.

In particular every Netburst event\nconsumes not just a counter and a config register, but also an\nadditional ESCR register.\n\nSince ESCR registers are grouped upon counters (i.e. if ESCR is occupied\nfor some event there is no room for another event to enter until its\nreleased) we need to pick up the \"least\" used ESCR (or the most available\none) for nmi-watchdog purposes -- so MSR_P4_CRU_ESCR2/3 was chosen.\n\nWith this patch nmi-watchdog and perf top should be able to run simultaneously.\n\nSigned-off-by: Cyrill Gorcunov \u003cgorcunov@openvz.org\u003e\nCC: Lin Ming \u003cming.m.lin@intel.com\u003e\nCC: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCC: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nTested-and-reviewed-by: Don Zickus \u003cdzickus@redhat.com\u003e\nTested-and-reviewed-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/20110623124918.GC13050@sun\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

Instead of\ncalling the generic truncate_setsize(), bring that code in so we can\ncall shmem_truncate_range() - which will later be updated to perform its\nown variant of truncate_inode_pages_range().\n\nRemove the punch_hole unmap_mapping_range() from shmem_truncate_range():\nnow that the COW\u0027s unmap_mapping_range() comes after -\u003etruncate_range,\nthere is no need to call it a third time.\n\nExport shmem_truncate_range() and add it to the list in shmem_fs.h, so\nthat i915_gem_object_truncate() can call it explicitly in future; get\nthis patch in first, then update drm/i915 once this is available (until\nthen, i915 will just be doing the truncate_inode_pages() twice).\n\nThough introduced five years ago, no other filesystem is implementing\n-\u003etruncate_range, and its only other user is madvise(,,MADV_REMOVE): we\nexpect to convert it to fallocate(,FALLOC_FL_PUNCH_HOLE,,) shortly,\nwhereupon -\u003etruncate_range can be removed from inode_operations -\nshmem_truncate_range() will help i915 across that transition too.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The eMMC card comes up at 3V, but drops to 1.65V\nafter the system resumes).\n\nSigned-off-by: Anand Gadiyar \u003cgadiyar@ti.com\u003e\nAcked-by: Balaji T K \u003cbalajitk@ti.com\u003e\nAcked-by: Venkatraman S \u003csvenkatr@ti.com\u003e\nTested-by: Kishore Kadiyala \u003ckishore.kadiyala@ti.com\u003e\nSigned-off-by: Sourav Poddar \u003csourav.poddar@ti.com\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n"

      "message": "mmc: sdio: fix runtime PM path during driver removal\n\nAfter commit e1866b3 \"PM / Runtime: Rework runtime PM handling\nduring driver removal\" was introduced, the driver core stopped\nincrementing the runtime PM usage counter of the device during\nthe invocation of the -\u003eremove() callback.\n\nThis indirectly broke SDIO\u0027s runtime PM path during driver removal,\nbecause no one calls _put_sync() anymore after -\u003eremove() completes.\n\nThis means that the power of runtime-PM-managed SDIO cards is kept\nhigh after their driver is removed (even if it was powered down\nbeforehand).\n\nFix that by directly calling _put_sync() when the last usage\ncounter is downref\u0027ed by the SDIO bus.\n\nReported-and-tested-by: Daniel Drake \u003cdsd@laptop.org\u003e\nSigned-off-by: Ohad Ben-Cohen \u003cohad@wizery.com\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n"
