      remove Documentation/smp.txt · 03502faa
      Adrian Bunk 提交于
      After seeing the filename I'd have expected something about the
      implementation of SMP in the Linux kernel - not some notes on kernel
      configuration and building trivialities noone would search at this
      place.

      Move Kconfig.instrumentation to arch/Kconfig and init/Kconfig · 125e5645
      Mathieu Desnoyers 提交于
      Move the instrumentation Kconfig to
      
      arch/Kconfig for architecture dependent options
        - oprofile
        - kprobes
      
      and
      
      init/Kconfig for architecture independent options
        - profiling
        - markers
      
      Remove the "Instrumentation Support" menu. Everything moves to "General setup".
      Delete the kernel/Kconfig.instrumentation file.

      Add HAVE_OPROFILE · 42d4b839
      Mathieu Desnoyers 提交于
      Linus:
      On the per-architecture side, I do think it would be better to *not* have
      internal architecture knowledge in a generic file, and as such a line like
      
              depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
      
      really shouldn't exist in a file like kernel/Kconfig.instrumentation.
      
      It would be much better to do
      
              depends on ARCH_SUPPORTS_KPROBES
      
      in that generic file, and then architectures that do support it would just
      have a
      
              bool ARCH_SUPPORTS_KPROBES
                      default y
      
      in *their* architecture files. That would seem to be much more logical,
      and is readable both for arch maintainers *and* for people who have no
      clue - and don't care - about which architecture is supposed to support
      which interface...
      
      Changelog:
      
      Actually, I know I gave this as the magic incantation, but now that I see
      it, I realize that I should have told you to just use
      
              config ARCH_SUPPORTS_KPROBES
                      def_bool y
      
      instead, which is a bit denser.
      
      We seem to use both kinds of syntax for these things, but this is really
      what "def_bool" is there for...
      
      Changelog :
      
      - Moving to HAVE_*.
      - Add AVR32 oprofile.

      spinlock: lockbreak cleanup · 95c354fe
      Nick Piggin 提交于
      The break_lock data structure and code for spinlocks is quite nasty.
      Not only does it double the size of a spinlock but it changes locking to
      a potentially less optimal trylock.
      
      Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a
      __raw_spin_is_contended that uses the lock data itself to determine whether
      there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is
      not set.
      
      Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to
      decouple it from the spinlock implementation, and make it typesafe (rwlocks
      do not have any need_lockbreak sites -- why do they even get bloated up
      with that break_lock then?).
