      s390/comments: unify copyright messages and remove file names · a53c8fab
      Heiko Carstens authored
      Remove the file name from the comment at top of many files. In most
      cases the file name was wrong anyway, so it's rather pointless.
      
      Also unify the IBM copyright statement. We did have a lot of sightly
      different statements and wanted to change them one after another
      whenever a file gets touched. However that never happened. Instead
      people start to take the old/"wrong" statements to use as a template
      for new files.
      So unify all of them in one go.

      ns: Wire up the setns system call · 7b21fddd
      Eric W. Biederman authored
      32bit and 64bit on x86 are tested and working.  The rest I have looked
      at closely and I can't find any problems.
      
      setns is an easy system call to wire up.  It just takes two ints so I
      don't expect any weird architecture porting problems.
      
      While doing this I have noticed that we have some architectures that are
      very slow to get new system calls.  cris seems to be the slowest where
      the last system calls wired up were preadv and pwritev.  avr32 is weird
      in that recvmmsg was wired up but never declared in unistd.h.  frv is
      behind with perf_event_open being the last syscall wired up.  On h8300
      the last system call wired up was epoll_wait.  On m32r the last system
      call wired up was fallocate.  mn10300 has recvmmsg as the last system
      call wired up.  The rest seem to at least have syncfs wired up which was
      new in the 2.6.39.
      
      v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
      v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
      v4: Moved wiring up of the system call to another patch
      v5: ported to v2.6.39-rc6
      v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
      v7: ported to Linus's latest post 2.6.39 tree.

      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. )

      [PATCH] remove remaining errno and __KERNEL_SYSCALLS__ references · 135ab6ec
      Arnd Bergmann authored
      The last in-kernel user of errno is gone, so we should remove the definition
      and everything referring to it.  This also removes the now-unused lib/execve.c
      file that was introduced earlier.
      
      Also remove every trace of __KERNEL_SYSCALLS__ that still remained in the
      kernel.

      [S390] Inline assembly cleanup. · 94c12cc7
      Martin Schwidefsky authored
      Major cleanup of all s390 inline assemblies. They now have a common
      coding style. Quite a few have been shortened, mainly by using register
      asm variables. Use of the EX_TABLE macro helps  as well. The atomic ops,
      bit ops and locking inlines new use the Q-constraint if a newer gcc
      is used.  That results in slightly better code.
      
      Thanks to Christian Borntraeger for proof reading the changes.
