Module Name:    src
Committed By:   dyoung
Date:           Tue Aug 23 22:00:58 UTC 2011

Modified Files:
        src/share/man/man9: vmem.9
        src/sys/kern: subr_vmem.c
        src/sys/rump/net/lib/libshmif: if_shmem.c
        src/sys/sys: vmem.h

Log Message:
Introduce a couple of new constants, VMEM_ADDR_MIN (the least possible
address in a vmem(9) arena, 0) and VMEM_ADDR_MAX (the maximum possible
address, currently 0xFFFFFFFF).  Modify several boundary conditions so
that a vmem(9) arena can allocate ranges including VMEM_ADDR_MAX.
Update documentation and tests.

These changes pass the tests in sys/kern/subr_vmem.c.  To compile the
and run the test program, run "cd sys/kern/ && gcc -DVMEM_SANITY -o
subr_vmem ./subr_vmem.c && ./subr_vmem".
