2009-05-15perf record: Allow specifying a pid to recordArnaldo Carvalho de Melo
Allow specifying a pid instead of always fork+exec'ing a command. Because the PERF_EVENT_COMM and PERF_EVENT_MMAP events happened before we connected, we must synthesize them so that 'perf report' can get what it needs.

2009-04-21spi: documentation: emphasise spi_master.setup() semanticsDavid Brownell
This is a doc-only patch which I hope will reduce the number of spi_master controller driver patches starting out with a common implementation bug. (As in: almost every spi_master driver I see starts out with its version of this bug. Sigh.) It just re-emphasizes that the setup() method may be called for one device while a transfer is active on another ... which means that most driver implementations shouldn't touch any registers.
