[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Clean up the page allocator interface a little. In particular
ChangeSet 1.1700, 2005/06/09 16:25:29+01:00, kaf24@xxxxxxxxxxxxxxxxxxxx
Clean up the page allocator interface a little. In particular
physical addresses are now passed as physaddr_t rather than unsigned
long (required for 32-bit pae mode).
