      m68k: Add NPTL support · 9674cdc7
      Maxim Kuvyrkov authored
      This patch adds several syscalls, that provide necessary
      functionality to support NPTL on m68k/ColdFire.
      The syscalls are get_thread_area, set_thread_area, atomic_cmpxchg_32 and
      atomic_barrier.
      The cmpxchg syscall is required for ColdFire as it doesn't support 'cas'
      instruction.
      
      Also a ptrace call PTRACE_GET_THREAD_AREA is added to allow debugger to
      inspect the TLS storage.

      perf: Do the big rename: Performance Counters -> Performance Events · cdd6c482
      Ingo Molnar authored
      Bye-bye Performance Counters, welcome Performance Events!
      
      In the past few months the perfcounters subsystem has grown out its
      initial role of counting hardware events, and has become (and is
      becoming) a much broader generic event enumeration, reporting, logging,
      monitoring, analysis facility.
      
      Naming its core object 'perf_counter' and naming the subsystem
      'perfcounters' has become more and more of a misnomer. With pending
      code like hw-breakpoints support the 'counter' name is less and
      less appropriate.
      
      All in one, we've decided to rename the subsystem to 'performance
      events' and to propagate this rename through all fields, variables
      and API names. (in an ABI compatible fashion)
      
      The word 'event' is also a bit shorter than 'counter' - which makes
      it slightly more convenient to write/handle as well.
      
      Thanks goes to Stephane Eranian who first observed this misnomer and
      suggested a rename.
      
      User-space tooling and ABI compatibility is not affected - this patch
      should be function-invariant. (Also, defconfigs were not touched to
      keep the size down.)
      
      This patch has been generated via the following script:
      
        FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')
      
        sed -i \
          -e 's/PERF_EVENT_/PERF_RECORD_/g' \
          -e 's/PERF_COUNTER/PERF_EVENT/g' \
          -e 's/perf_counter/perf_event/g' \
          -e 's/nb_counters/nb_events/g' \
          -e 's/swcounter/swevent/g' \
          -e 's/tpcounter_event/tp_event/g' \
          $FILES
      
        for N in $(find . -name perf_counter.[ch]); do
          M=$(echo $N | sed 's/perf_counter/perf_event/g')
          mv $N $M
        done
      
        FILES=$(find . -name perf_event.*)
      
        sed -i \
          -e 's/COUNTER_MASK/REG_MASK/g' \
          -e 's/COUNTER/EVENT/g' \
          -e 's/\<event\>/event_id/g' \
          -e 's/counter/event/g' \
          -e 's/Counter/Event/g' \
          $FILES
      
      ... to keep it as correct as possible. This script can also be
      used by anyone who has pending perfcounters patches - it converts
      a Linux kernel tree over to the new naming. We tried to time this
      change to the point in time where the amount of pending patches
      is the smallest: the end of the merge window.
      
      Namespace clashes were fixed up in a preparatory patch - and some
      stylistic fallout will be fixed up in a subsequent patch.
      
      ( NOTE: 'counters' are still the proper terminology when we deal
        with hardware registers - and these sed scripts are a bit
        over-eager in renaming them. I've undone some of that, but
        in case there's something left where 'counter' would be
        better than 'event' we can undo that on an individual basis
        instead of touching an otherwise nicely automated patch. )

      m68k,m68knommu: merge header files · 49148020
      Sam Ravnborg authored
      Merge header files for m68k and m68knommu to the single location:
      
          arch/m68k/include/asm
      
      The majority of this patch was the result of the
      script that is included in the changelog below.
      
      The script was originally written by Arnd Bergman and
      exten by me to cover a few more files.
      
      When the header files differed the script uses the following:
      
      The original m68k file is named <file>_mm.h  [mm for memory manager]
      The m68knommu file is named <file>_no.h [no for no memory manager]
      
      The files uses the following include guard:
      
      This include gaurd works as the m68knommu toolchain set
      the __uClinux__ symbol - so this should work in userspace too.
      
      Merging the header files for m68k and m68knommu exposes the
      (unexpected?) ABI differences thus it is easier to actually
      identify these and thus to fix them.
      
      The commit has been build tested with both a m68k and
      a m68knommu toolchain - with success.
      
      The commit has also been tested with "make headers_check"
      and this patch fixes make headers_check for m68knommu.
