alc 2008-06-22 04:54:27 UTC FreeBSD src repository Modified files: sys/vm vm_kern.c Log: SVN rev 179923 on 2008-06-22 04:54:27Z 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, the memory allocated during bootstrap, before the call to kmem_init(), starts at KERNBASE, which is not necessarily the same as VM_MIN_KERNEL_ADDRESS on amd64. Revision Changes Path 1.135 +6 -2 src/sys/vm/vm_kern.c
