Log Message:
Introduce a new set of PTE bits, with a different naming convention.
PG_V -> PTE_P /* Present */
PG_RW -> PTE_W /* Write */
PG_u -> PTE_U /* User */
PG_WT -> PTE_PWT /* Write-Through */
PG_N -> PTE_PCD /* Cache-Disable */
PG_U -> PTE_A /* Accessed */
PG_M -> PTE_D /* Dirty */
PG_PAT -> PTE_PAT /* PAT on 4KB Pages */
PG_PS -> PTE_PS /* Large Page Size */
PG_G -> PTE_G /* Global Translation */
PG_AVAIL1 -> PTE_AVL1 /* Ignored by Hardware */
PG_AVAIL2 -> PTE_AVL2 /* Ignored by Hardware */
PG_AVAIL3 -> PTE_AVL3 /* Ignored by Hardware */
PG_LGPAT -> PTE_LGPAT /* PAT on Large Pages */
PG_NX -> PTE_NX /* No Execute */
Until now we were using "PG_BIT". The "BIT" part of the naming did not
follow the x86 naming convention in the spec, and was very confusing. We
don't want the "PG_" part of it either, because UVM has similar flags
(ie PG_BUSY).
