alc 2008-06-20 05:22:09 UTC FreeBSD src repository Modified files: sys/amd64/amd64 mem.c pmap.c trap.c sys/amd64/include pmc_mdep.h stack.h Log: SVN rev 179886 on 2008-06-20 05:22:09Z by alc Make preparations for increasing the size of the kernel virtual address space on the amd64 architecture. The amd64 architecture requires kernel code and global variables to reside in the highest 2GB of the 64-bit virtual address space. Thus, KERNBASE cannot change. However, KERNBASE is sometimes used as the start of the kernel virtual address space. Henceforth, VM_MIN_KERNEL_ADDRESS should be used instead. Since KERNBASE and VM_MIN_KERNEL_ADDRESS are still the same address, there should be no visible effect from this change (yet).
