      oprofile: Remove 'WQ on CPUx, prefer CPUy' warning · 61bccf19
      Robert Richter authored
      Under certain workloads we see the following warnings:
      
       WQ on CPU0, prefer CPU1
       WQ on CPU0, prefer CPU2
       WQ on CPU0, prefer CPU3
      
      It warns the user that the wq to access a per-cpu buffers runs not on
      the same cpu. This happens if the wq is rescheduled on a different cpu
      than where the buffer is located. This was probably implemented to
      detect performance issues. Not sure if there actually is one as the
      buffers are copied to a single buffer anyway which should be the
      actual bottleneck.
      
      We wont change WQ implementation. Since a user can do nothing the
      warning is pointless. Removing it.

      oprofile, s390: Fix uninitialized memory access when writing to oprofilefs · 81ff3478
      Robert Richter authored
      If oprofilefs_ulong_from_user() is called with count equals zero, *val
      remains unchanged. Depending on the implementation it might be
      uninitialized. Fixing users of oprofilefs_ulong_ from_user().

      perf/x86: Fix microcode revision check for SNB-PEBS · e3e45c01
      Stephane Eranian authored
      The following patch makes the microcode update code path
      actually invoke the perf_check_microcode() function and
      thus potentially renabling SNB PEBS.
      
      By default, CONFIG_MICROCODE_OLD_INTERFACE is
      forced to Y in arch/x86/Kconfig. There is no
      way to disable this. That means that the code
      path used in arch/x86/kernel/microcode_core.c
      did not include the call to perf_check_microcode().
      
      Thus, even though the microcode was updated to a
      version that fixes the SNB PEBS problem, perf_event
      would still return EOPNOTSUPP when enabling precise
      sampling.
      
      This patch simply adds a call to perf_check_microcode()
      in the call path used when OLD_INTERFACE=y.

         provide a blk_bio_map_sg() helper.  Useful for mapping just a bio
         instead of a full request.
      
       - Regression fix from Hugh, fixing up a patch that went into the
         previous release cycle (and marked stable, too) attempting to prevent
         a loop in __getblk_slow().
      
       - Updates to discard requests, fixing up the sizing and how we align
         them.  Also a change to disallow merging of discard requests, since
         that doesn't really work properly yet.
