        src/sys/arch/xen/x86: xen_shm_machdep.c
        src/sys/kern: subr_kmem.c subr_percpu.c subr_vmem.c
        src/sys/rump/net/lib/libshmif: if_shmem.c
        src/sys/sys: vmem.h
        src/sys/uvm: uvm_emap.c uvm_swap.c

Log Message:
Report vmem(9) errors out-of-band so that we can use vmem(9) to manage
ranges that include the least and the greatest vmem_addr_t.  Update
vmem(9) uses throughout the kernel.  Slightly expand on the tests in
subr_vmem.c, which still pass.  I've been running a kernel with this
patch without any trouble.
