2013-09-19perf probe: Fix finder to find lines of given functionMasami Hiramatsu3-7/+27
The commit ba28c59bc9ed8fb7b9a753cd88ee54a2c4f6265b fixed a declaration entry bug in probe_point_search_cb(). There are same bugs in line finder and call_probe_finder(). This introduces a new dwarf utility function to determine given DIE is a function definition, not declaration.

2013-09-19perf tools: Fix buildid cache handling of kallsyms with kcoreAdrian Hunter1-13/+28
When kallsyms is used with kcore the dso long_name becomes the kcore file name. That prevents the buildid cache from caching kallsyms. (There is no support at present for caching kcore). Fix by changing it so that the kallsyms name is used in that case instead.

2013-09-19perf annotate: Fix objdump line parsing offset validationAdrian Hunter1-1/+1
When parsing lines from objdump a line containing source code starting with a numeric label is mistaken for a line of disassembly starting with a memory address. Current validation fails to recognise that the "memory address" is out of range and calculates an invalid offset which later causes this segfault: Program received signal SIGSEGV, Segmentation fault. 0x0000000000457315 in disasm__calc_percent (notes=0xc98970, evidx=0, offset=143705, end=2127526177, path=0x7fffffffbf50) at util/annotate.c:631 631 hits += h->addr[offset++]; (gdb) bt #0 0x0000000000457315 in disasm__calc_percent (notes=0xc98970, evidx=0, offset=143705, end=2127526177, path=0x7fffffffbf50) at util/annotate.c:631 #1 0x00000000004d65e3 in annotate_browser__calc_percent (browser=0x7fffffffd130, evsel=0xa01da0) at ui/browsers/annotate.c:364 #2 0x00000000004d7433 in annotate_browser__run (browser=0x7fffffffd130, evsel=0xa01da0, hbt=0x0) at ui/browsers/annotate.c:672 #3 0x00000000004d80c9 in symbol__tui_annotate (sym=0xc989a0, map=0xa02660, evsel=0xa01da0, hbt=0x0) at ui/browsers/annotate.c:962 #4 0x00000000004d7aa0 in hist_entry__tui_annotate (he=0xdf73f0, evsel=0xa01da0, hbt=0x0) at ui/browsers/annotate.c:823 #5 0x00000000004dd648 in perf_evsel__hists_browse (evsel=0xa01da0, nr_events=1, helpline= 0x58b768 "For a higher level overview, try: perf report --sort comm,dso", ev_name=0xa02cd0 "cycles", left_exits=false, hbt= 0x0, min_pcnt=0, env=0xa011e0) at ui/browsers/hists.c:1659 #6 0x00000000004de372 in perf_evlist__tui_browse_hists (evlist=0xa01520, help= 0x58b768 "For a higher level overview, try: perf report --sort comm,dso", hbt=0x0, min_pcnt=0, env=0xa011e0) at ui/browsers/hists.c:1950 #7 0x000000000042cf6b in __cmd_report (rep=0x7fffffffd6c0) at builtin-report.c:581 #8 0x000000000042e25d in cmd_report (argc=0, argv=0x7fffffffe4b0, prefix=0x0) at builtin-report.c:965 #9 0x000000000041a0e1 in run_builtin (p=0x801548, argc=1, argv=0x7fffffffe4b0) at perf.c:319 #10 0x000000000041a319 in handle_internal_command (argc=1, argv=0x7fffffffe4b0) at perf.c:376 #11 0x000000000041a465 in run_argv (argcp=0x7fffffffe38c, argv=0x7fffffffe380) at perf.c:420 #12 0x000000000041a707 in main (argc=1, argv=0x7fffffffe4b0) at perf.c:521 After the fix is applied the symbol can be annotated showing the problematic line "1: rep" copy_user_generic_string /usr/lib/debug/lib/modules/3.9.10-100.fc17.x86_64/vmlinux */ ENTRY(copy_user_generic_string) CFI_STARTPROC ASM_STAC andl %edx,%edx and %edx,%edx jz 4f je 37 cmpl $8,%edx cmp $0x8,%edx jb 2f /* less than 8 bytes, go to byte copy loop */ jb 33 ALIGN_DESTINATION mov %edi,%ecx and $0x7,%ecx je 28 sub $0x8,%ecx neg %ecx sub %ecx,%edx 1a: mov (%rsi),%al mov %al,(%rdi) inc %rsi inc %rdi dec %ecx jne 1a movl %edx,%ecx 28: mov %edx,%ecx shrl $3,%ecx shr $0x3,%ecx andl $7,%edx and $0x7,%edx 1: rep 100.00 rep movsq %ds:(%rsi),%es:(%rdi) movsq 2: movl %edx,%ecx 33: mov %edx,%ecx 3: rep rep movsb %ds:(%rsi),%es:(%rdi) movsb 4: xorl %eax,%eax 37: xor %eax,%eax data32 xchg %ax,%ax ASM_CLAC ret retq Signed-off-by: Adrian Hunter <[email protected]> Cc: David Ahern <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Mike Galbraith <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2013-09-19MIPS: Disable usermode switching of the FR bit for MIPS R5 CPUs.Ralf Baechle1-0/+13
Currently the kernel will always use the FR=0 register model for O32. If an O32 application did enable FR=1 mode, some data from another application might be leaked in the extra registers becoming visible. Iow, this patch is meant to make the kernel MIPS R5 tolerant but leaves proper MIPS R5 support to a future patchset. Signed-off-by: Ralf Baechle <[email protected]>

2013-09-19drm/fb-helper: don't sleep for screen unblank when an oops is in progressDaniel Vetter1-0/+8
Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes" assumed the pdev->dev is set to cpu0 device in the platform code. But it actually points to the virtual cpufreq-cpu0 platform device which is not present in the device tree. Most of the information needed by cpufreq is stored in cpu0 DT node.

2013-09-19drm/ttm: fix the tt_populated check in ttm_tt_destroy()Ben Skeggs1-1/+1
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations.

There's no need to keep the legacy naming as omap4 is DT only nowadays.

2013-09-18iio: at91: fix adc_clk overflowJosh Wu1-5/+6
The adc_clk variable is currently defined using a 32-bits unsigned integer, which will overflow under some very valid range of operations. Such overflow will occur if, for example, the parent clock is set to a 20MHz frequency and the ADC startup time is larger than 215ns. To fix this, introduce an intermediate variable holding the clock rate in kHz.

2013-09-18dm stats: fix possible counter corruption on 32-bit systemsMikulas Patocka1-6/+17
There was a deliberate race condition in dm_stat_for_entry() to avoid the overhead of disabling and enabling interrupts. The race could result in some events not being counted on 64-bit architectures. However, on 32-bit architectures, operations on long long variables are not atomic, so the race condition could cause the counter to jump by 2^32. Such jumps could be disruptive, so we need to do proper locking on 32-bit architectures. Signed-off-by: Mikulas Patocka <[email protected]> Cc: Alasdair G.

2013-09-18dm mpath: do not fail path on -ENOSPCJun'ichi Nomura1-0/+1
Since ENOSPC is a target-side error, dm-mpath should just pass the error information to upper layer instead of retrying itself with path failover. Otherwise it will end up failing all paths down while path checkers find all paths ok.

2013-09-18cnic: Fix crash in cnic_bnx2x_service_kcq()Michael Chan1-1/+2
commit 104a43edb264321a4d41850e98153b4fa8a9ef42 cnic: Use CHIP_NUM macros from bnx2x.h changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE is supported or not. There is another place in cnic that is still using the old method to determine if FCoE is supported or not. The 2 methods may not yield the same result after the network interface is brought down and up. This will cause the crash as cnic_bnx2x_service_kcq() will access the uninitialized cp->kcq2. The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code to remove the old method as it is no longer needed.
