      sata_rcar: clear STOP bit in bmdma_start() method · df7e131f
      Sergei Shtylyov authored
      Iff bmdma_setup() has to stop a DMA transfer before starting a new
      one, then the STOP bit in the ATAPI_CONTROL1 register will remain set
      (it's only cleared when setting the START bit to 1) and then
      bmdma_start() method will set both START and STOP bits simultaneously
      which should abort the transfer being just started.  Avoid that by
      explicitly clearing the STOP bit in bmdma_start() method (in this case
      it will be ignored on write).

      libata: make ata_exec_internal_sg honor DMADIR · e771451c
      Vincent Pelletier authored
      libata honors DMADIR for regular commands, but not for internal commands
      used (among other) during device initialisation.
      
      This makes SATA-host-to-PATA-device bridges based on Silicon Image SiL3611
      (such as "Abit Serillel 2") end up disabled when used with an ATAPI device
      after a few tries.
      
      Log output of the bridge being hot-plugged with an ATAPI drive:

      Pull tracing/kprobes update from Steven Rostedt:
       "The majority of these changes are from Masami Hiramatsu bringing
        kprobes up to par with the latest changes to ftrace (multi buffering
        and the new function probes).
      
        He also discovered and fixed some bugs in doing so.  When pulling in
        his patches, I also found a few minor bugs as well and fixed them.
      
        This also includes a compile fix for some archs that select the ring
        buffer but not tracing.
      
        I based this off of the last patch you took from me that fixed the
        merge conflict error, as that was the commit that had all the changes
        I needed for this set of changes."
