      Build with -fno-dwarf2-cfi-asm · 00308649
      Kyle McMartin authored
      With a sufficiently new compiler and binutils, code which wasn't
      previously generating .eh_frame sections has begun to.  Certain
      architectures (powerpc, in this case) may generate unexpected relocation
      formats in response to this, preventing modules from loading.
      
      While the new relocation types should probably be handled, revert to the
      previous behaviour with regards to generation of .eh_frame sections.
      
      (This was reported against Fedora, which appears to be the only distro
      doing any building against gcc-4.4 at present: RH bz#486545.)

      fix ptrace slowness · 53da1d94
      Miklos Szeredi authored
      This patch fixes bug #12208:
      
        Bug-Entry       : http://bugzilla.kernel.org/show_bug.cgi?id=12208
        Subject         : uml is very slow on 2.6.28 host
      
      This turned out to be not a scheduler regression, but an already
      existing problem in ptrace being triggered by subtle scheduler
      changes.
      
      The problem is this:
      
       - task A is ptracing task B
       - task B stops on a trace event
       - task A is woken up and preempts task B
       - task A calls ptrace on task B, which does ptrace_check_attach()
       - this calls wait_task_inactive(), which sees that task B is still on the runq
       - task A goes to sleep for a jiffy
       - ...
      
      Since UML does lots of the above sequences, those jiffies quickly add
      up to make it slow as hell.
      
      This patch solves this by not rescheduling in read_unlock() after
      ptrace_stop() has woken up the tracer.
      
      Thanks to Oleg Nesterov and Ingo Molnar for the feedback.

      Grant picked up the wrong version of "Respect _PAGE_COHERENT on classic
      ppc32 SW" (commit a4bd6a93)
      
      It was missing the code to actually deal with the fixup of
      _PAGE_COHERENT based on the CPU feature.

      ucc_geth: Fix oops when using fixed-link support · 61fa9dcf
      Anton Vorontsov authored
      commit b1c4a9dd ("ucc_geth: Change
      uec phy id to the same format as gianfar's") introduced a regression
      in the ucc_geth driver that causes this oops when fixed-link is used:

      This patch fixes the issue by removing offending (and somewhat
      duplicate) code from init_phy() routine, and changes _probe()
      function to use uec_mdio_bus_name().
      
      Also, since we fully construct phy_bus_id in the _probe() routine,
      we no longer need ->phy_address and ->mdio_bus fields in
      ucc_geth_info structure.
      
      I wish the patch would be a bit shorter, but it seems like the only
      way to fix the issue in a sane way. Luckily, the patch has been
      tested with real PHYs and fixed-link, so no further regressions
      expected.
