2014-04-10hwlat-detector: Use thread instead of stop machineSteven Rostedt
There's no reason to use stop machine to search for hardware latency. Simply disabling interrupts while running the loop will do enough to check if something comes in that wasn't disabled by interrupts being off, which is exactly what stop machine does. Instead of using stop machine, just have the thread disable interrupts while it checks for hardware latency.

2014-04-10hwlat-detector: Use trace_clock_local if availableSteven Rostedt
As ktime_get() calls into the timing code which does a read_seq(), it may be affected by other CPUS that touch that lock. To remove this dependency, use the trace_clock_local() which is already exported for module use. If CONFIG_TRACING is enabled, use that as the clock, otherwise use ktime_get().

2014-04-10hwlat-detector: Update hwlat_detector to add outer loop detectionSteven Rostedt
The hwlat_detector reads two timestamps in a row, then reports any gap between those calls. The problem is, it misses everything between the second reading of the time stamp to the first reading of the time stamp in the next loop. That's were most of the time is spent, which means, chances are likely that it will miss all hardware latencies. This defeats the purpose. By also testing the first time stamp from the previous loop second time stamp (the outer loop), we are more likely to find a latency. Setting the threshold to 1, here's what the report now looks like: 1347415723.0232202770 0 2 1347415725.0234202822 0 2 1347415727.0236202875 0 2 1347415729.0238202928 0 2 1347415731.0240202980 0 2 1347415734.0243203061 0 2 1347415736.0245203113 0 2 1347415738.0247203166 2 0 1347415740.0249203219 0 3 1347415742.0251203272 0 3 1347415743.0252203299 0 3 1347415745.0254203351 0 2 1347415747.0256203404 0 2 1347415749.0258203457 0 2 1347415751.0260203510 0 2 1347415754.0263203589 0 2 1347415756.0265203642 0 2 1347415758.0267203695 0 2 1347415760.0269203748 0 2 1347415762.0271203801 0 2 1347415764.0273203853 2 0 There's some hardware latency that takes 2 microseconds to run.

MIC card and host drivers are able to use virtio over the PCIe bus by treating ioremap return values for the prefetchable BARs as pointers, effectively treating I/O memory the same as system memory. However this results in sparse warnings. Knowing that these warnings do not point to a functional issue, this patch suppresses these warnings.

Endianness issues are now consistent as per the documentation in host/mic_virtio.h. Sparse warnings related to endianness are also fixed. Note that the MIC driver implementation assumes that the host can be both BE or LE whereas the card is always LE.

2013-11-27misc: mic: Fix user space namespace pollution from mic_common.h.Ashutosh Dixit
Avoid declaring ALIGN() and __aligned() in include/uapi/linux/mic_common.h since they pollute user space namespace. Also, mic_aligned_size() can be simply replaced simply by sizeof() since all structures where mic_aligned_size() is used are declared using __attribute__ ((aligned(8))); -- >From mail from H Peter Anvin about this: On Fri, Nov 08, 2013 H Peter Anvin <h.peter.anvin@intel.com> wrote: Subject: Namespace pollution in mic_common.h This puts two macros, ALIGN() and __aligned(), into arbitrary user space namespace. This really isn't safe or acceptable, especially since those symbols are highly generic. ... When these structures are forced-aligned, they will in fact have padding automatically added by the compiler to an 8-byte boundary anyway, so mic_aligned_size() does nothing. ...

commit 5c6d6fd1564138ad048564e48639f842714a90c6 upstream. Two drivers (atmel-pwm-bl and leds-atmel-pwm) currently depend on the atmel_pwm driver to have bound to any pwm-device before their devices are probed. Support deferred probing of such devices by making sure to return -EPROBE_DEFER from pwm_channel_alloc when no pwm-device has yet been bound.
