cognet 2007-12-07 22:28:49 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) sys/arm/arm pmap.c Log: MFC rev 1.90: Fix a potential bug in pmap : We used to allocate the domains 0-14 for userland, and leave the domain 15 for the kernel. Now supersections requires the use of domain 0, so we switched the kernel domain to 0, and use 1-15 for userland. How it's done currently, the kernel domain could be allocated for a userland process. So switch back to the previous way we did things, set the first available domain to 0, and just add 1 to get the real domain number in the struct pmap.
