2013-11-14dmatest: support xor-only, or pq-only channels in testsDan Williams
Currently we only test raid channels that happen to also have 'copy' capability. Search for capable channels that do not have DMA_MEMCPY. Note the return value from run_threaded_test never really made sense because it could return errors after successfully starting tests. We already have the test results per channel so missing channels can be detected at that time.

2013-11-14dmatest: restore ability to start test at module load and initDan Williams
1/ move 'run' control to a module parameter so we can do: modprobe dmatest run=1. With this moved the rest of the debugfs boilerplate can go. 2/ Fix parameter initialization. Previously the test was being started without taking the parameters into account in the built-in case. Also killed off the '__' version of some routines. The new rule is just hold the lock when calling a *threaded_test() routine.

2013-11-14dmatest: replace stored results mechanism, with uniform messagesDan Williams
For long running tests the tracking results in a memory leak for the "ok" results, and for the failures the kernel log should be sufficient. Provide a uniform format for error messages so they can be easily parsed and remove the debugfs file.

2013-11-14Revert "dmatest: append verify result to results"Dan Williams
This reverts commit d86b2f298e6de124984f5d5817ed1e6e759b3ada. The kernel log buffer is sufficient for collecting test results. The current logging OOMs the machine on long running tests, and usually only the first error is relevant. It is better to stop on error and parse the kernel output. If output volume becomes an issue we can always investigate using trace messages.

2013-11-14perf tools: Synthesize anon MMAP records againDon Zickus
When introducing the PERF_RECORD_MMAP2 in: 5c5e854bc760 perf tools: Add attr->mmap2 support A check for the number of entries parsed by sscanf was introduced that assumed all of the 8 fields needed to be correctly parsed so that particular /proc/pid/maps line would be considered synthesizable. That broke anon records synthesizing, as it doesn't have the 'execname' field. Fix it by keeping the sscanf return check, changing it to not require that the 'execname' variable be parsed, so that the preexisting logic can kick in and set it to '//anon'. This should get things like JIT profiling working again.

2013-11-14i2c: exynos5: Remove incorrect clk_disable_unprepareSachin Kamat
clk_disable_unprepare in remove causes an imbalance and hence gives the below crash on module remove. While at it also remove some duplicate code from probe. / $ rmmod i2c-exynos5 [ 6.996374] ------------[ cut here ]------------ [ 6.999523] WARNING: CPU: 2 PID: 1137 at drivers/clk/clk.c:842 clk_disable+0x18/0x24() [ 7.007403] Modules linked in: i2c_exynos5(-) [ 7.011747] CPU: 2 PID: 1137 Comm: rmmod Not tainted 3.12.0-next-20131105-00083-g16f4799-dirty #21 [ 7.020696] [<c0014e0c>] (unwind_backtrace+0x0/0xf4) from [<c0011784>] (show_stack+0x10/0x14) [ 7.029190] [<c0011784>] (show_stack+0x10/0x14) from [<c037acd4>] (dump_stack+0x7c/0xb0) [ 7.037255] [<c037acd4>] (dump_stack+0x7c/0xb0) from [<c001e0ac>] (warn_slowpath_common+0x6c/0x88) [ 7.046190] [<c001e0ac>] (warn_slowpath_common+0x6c/0x88) from [<c001e164>] (warn_slowpath_null+0x1c/0x24) [ 7.055818] [<c001e164>] (warn_slowpath_null+0x1c/0x24) from [<c02dcde4>] (clk_disable+0x18/0x24) [ 7.064670] [<c02dcde4>] (clk_disable+0x18/0x24) from [<bf0002d4>] (exynos5_i2c_remove+0x1c/0x34 [i2c_exynos5]) [ 7.074736] [<bf0002d4>] (exynos5_i2c_remove+0x1c/0x34 [i2c_exynos5]) from [<c02274a8>] (__device_release_driver+0x58/0xb0) [ 7.085836] [<c02274a8>] (__device_release_driver+0x58/0xb0) from [<c0227b88>] (driver_detach+0xac/0xb0) [ 7.095291] [<c0227b88>] (driver_detach+0xac/0xb0) from [<c02271c0>] (bus_remove_driver+0x4c/0xa0) [ 7.104227] [<c02271c0>] (bus_remove_driver+0x4c/0xa0) from [<c00725dc>] (SyS_delete_module+0x124/0x194) [ 7.113682] [<c00725dc>] (SyS_delete_module+0x124/0x194) from [<c000e2e0>] (ret_fast_syscall+0x0/0x30) [ 7.122957] ---[ end trace 23bb6e4e0bf52196 ]--- Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-11-14i2c: i2c-st: Add ST I2C controllerMaxime COQUELIN
This patch adds support to SSC (Synchronous Serial Controller) I2C driver. This IP also supports SPI protocol, but this is not the aim of this driver. This IP is embedded in all ST SoCs for Set-top box platorms, and supports I2C Standard and Fast modes.

2013-11-14ASoC: wm8962: Turn on regcache_cache_only before disabling regulatorNicolin Chen
It's safer to turn on regcache_cache_only before disabling regulator since the driver will turn off the regcache_cache_only after enabling regulator. If we remain cache_only false, some command like 'amixer cset' would get failure if being run before wm8962_resume().

2013-11-14tools/perf/build: Fix feature-libunwind-debug-frame handlingIngo Molnar
Set feature-libunwind-debug-frame. We don't want it in CORE_FEATURE_TESTS because it's not the generic case, but we need to set it in the !feature-libunwind case. Also, because x86 distributions typically don't have dwarf_find_debug_frame() unwinding method: test-libunwind-debug-frame.c:(.text+0x31): undefined reference to `_Ux86_64_dwarf_find_debug_frame' Restrict this new API to ARM for the time being. With this patch test-all.c works again, so repeat perf builds are fast again: comet:~/tip> perf stat --null --repeat 5 make -C tools/perf/ [...] 0,452899660 seconds time elapsed ( +- 0,11% ) While with before it was: comet:~/tip> perf stat --null --repeat 5 make -C tools/perf/ [...] 1,674001829 seconds time elapsed ( +- 0,16% ) [ Includes fix to config/feature-checks/Makefile from Will Deacon. ] Tested-by: Will Deacon <will.deacon@arm.com> Tested-by: Jean Pihet <jean.pihet@linaro.org> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Arnaldo Carvalho de Melo <acme@infradead.org> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-scsoctqzmou3rpkixCHezy9e@git.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
