Commit Message

Adhemerval Zanella Netto Oct. 8, 2014, 9:32 p.m. UTC
This patch changes the way cancellation entrypoints are defined to
instead call the macro SYSCALL_CANCEL.  An usual cancellation is defined as:

  if (SINGLE_THREAD_P)
    return INLINE_SYSCALL (syscall, NARGS, args...)

  int oldtype = LIBC_CANCEL_ASYNC ();

  return INLINE_SYSCALL (syscall, NARGS, args...)

  LIBC_CANCEL_RESET (oldtype);

And it is rewrited as just:

  SYSCALL_CANCEL (syscall, args...)

The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET direct
usage.

This patch does not change libc semantics and still left some place with 
LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET where the change it will require
more intensive change (basically where INLINE_SYSCALL_NCS is used).

Checked on x86_64, ppc64, and ppc32.
