      Delete filenames in comments. · 835c34a1
      Dave Jones authored
      Since the x86 merge, lots of files that referenced their own filenames
      are no longer correct.  Rather than keep them up to date, just delete
      them, as they add no real value.
      - fix up comment formatting in scx200_32.c
      - Remove a credit from myself in setup_64.c from a time when we had no SCM
      - remove longwinded history from tsc_32.c which can be figured out from

      Fix spurious syscall tracing after PTRACE_DETACH + PTRACE_ATTACH · 7d941432
      Roland McGrath authored
      When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the
      TIF_SYSCALL_TRACE flag is left set on the formerly-traced task.  This
      means that when a new tracer comes along and does PTRACE_ATTACH, it's
      possible he gets a syscall tracing stop even though he's never used
      PTRACE_SYSCALL.  This happens if the task was in the middle of a system
      call when the second PTRACE_ATTACH was done.  The symptom is an
      unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have
      been provoked by his ptrace calls so far.
      A few machines already fixed this in ptrace_disable (i386, ia64, m68k).
      But all other machines do not, and still have this bug.  On x86_64, this
      constitutes a regression in IA32 compatibility support.
      Since all machines now use TIF_SYSCALL_TRACE for this, I put the
      clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather
      than adding it to every other machine's ptrace_disable.

      [PATCH] ptrace: Fix EFL_OFFSET value according to i386 pda changes · 8701ea95
      Jeremy Fitzhardinge authored
      The PDA patches introduced a bug in ptrace: it reads eflags from the wrong
      place on the target's stack, but writes it back to the correct place.  The
      result is a corrupted eflags, which is most visible when it turns interrupts
      off unexpectedly.
      This patch fixes this by making the ptrace code a little less fragile.  It
      changes [gs]et_stack_long to take a straightforward byte offset into struct
      pt_regs, rather than requiring all callers to do a sizeof(struct pt_regs)
      offset adjustment.  This means that the eflag's offset (EFL_OFFSET) on the
      target stack can be simply computed with offsetof().
