linux: more users of __pte_val/__p[mug]d_val
PATCH 1/1 linux: more users of __pte_val/__p[mug]d_val
Use __pXX_val() instead of pXX_val() when only flags are accessed or the frame number is only compared against zero
As usual, written and tested against 2.6.23 and made apply against 2.6.18 without further testing.
