      signals: demultiplexing SIGTRAP signal · da654b74
      Srinivasa Ds 提交于
      Currently a SIGTRAP can denote any one of below reasons.
      	- Breakpoint hit
      	- H/W debug register hit
      	- Single step
      	- Signal sent through kill() or rasie()
      
      Architectures like powerpc/parisc provides infrastructure to demultiplex
      SIGTRAP signal by passing down the information for receiving SIGTRAP through
      si_code of siginfot_t structure. Here is an attempt is generalise this
      infrastructure by extending it to x86 and x86_64 archs.

      x86: consolidate header guards · 77ef50a5
      Vegard Nossum 提交于
      This patch is the result of an automatic script that consolidates the
      format of all the headers in include/asm-x86/.
      
      The format:
      
      1. No leading underscore. Names with leading underscores are reserved.
      2. Pathname components are separated by two underscores. So we can
         distinguish between mm_types.h and mm/types.h.
      3. Everything except letters and numbers are turned into single
         underscores.

      x86, ptrace: PEBS support · 93fa7636
      Markus Metzger 提交于
      Polish the ds.h interface and add support for PEBS.
      
      Ds.c is meant to be the resource allocator for per-thread and per-cpu
      BTS and PEBS recording.
      It is used by ptrace/utrace to provide execution tracing of debugged tasks.
      It will be used by profilers (e.g. perfmon2).
      It may be used by kernel debuggers to provide a kernel execution trace.
      
      Changes in detail:
      - guard DS and ptrace by CONFIG macros
      - separate DS and BTS more clearly
      - simplify field accesses
      - add functions to manage PEBS buffers
      - add simple protection/allocation mechanism
      - added support for Atom
      
      Opens:
      - buffer overflow handling
        Currently, only circular buffers are supported. This is all we need
        for debugging. Profilers would want an overflow notification.
        This is planned to be added when perfmon2 is made to use the ds.h
        interface.
      - utrace intermediate layer
