[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Rename some of the pagetable access macros:
ChangeSet 1.1624, 2005/06/01 10:06:47+01:00, kaf24@xxxxxxxxxxxxxxxxxxxx
Rename some of the pagetable access macros:
l?e_create_* -> l?e_from_*
*_phys -> *_paddr
*_value -> *_intpte
l?e_add_flags, l?e_remove_flags, l?e_has_changed now take ptes by value
rather than by reference.
The pagetable hypercalls are fixed to use l?e_from_intpte() rather than
abusing l?e_from_paddr(), which munged the NX bit incorrectly on x86/64.
Thanks to Scott Parish for spotting this one.
