[PATCH][2.6.10-rc1-mm5][1/3] perfctr x86 driver cleanup

[Mikael Pettersson]

x86 driver cleanup to be applied on top of yesterday's perfctr
interrupt fixes patches:
- Provide API function for checking for pending interrupts.
  Avoids direct structure access in higher levels, which is
  required for ppc32.
