: The first batch of changes are attached (also at
: http://people.freebsd.org/~jchandra/jmallett-merge/), the patches are:
: 
: libc-asm.patch - change libc assembly code to use macros which work on o32/n64
: libc-other.patch - makecontext implemenation, and other cleanup
: ld.so.patch - change dynamic loader assembly code to use macros
: tlb-to-c.patch - move TLB operations to C, update TLB operations API
: 
: I've tested this on XLR, but there is a chance that this might break
: other platforms. So please let me know your comments on both the
: patches and the merge process.

I've reviewed these changes with Juli as she was committing them to
her branch.  I think they are good to go.

: The future patches (if everything goes well), will do the PTE_ flag to
: PG_ flag renaming in Juli's tree, then the actual n32/n64 changes.
