[PATCH][2.6] VR41xx pte fix and VR413x cpu-probe fix

[Dimitri Torfs <dimitri@sonycom.com>]

Hi,

  here are two patches related to the VR41xx series. The first patch
  fixes the pte calculation (pte_pfn and pfn_pte) for VR41xx. Second
  patch fixes the cpu detection for the VR413x cpu's (missing break).
