>Description:
If compiling a kernel with options XENHVM the build will fail unless you also
have options SMP.

*** Error code 1
Stop.
I don't know this dependency is a problem per se but it should be documented,
e.g in xen(4) or in comments in GENERIC or if it is documented then documented
in bigger letters :-)
>How-To-Repeat:
cd /usr/src/sys/amd64/conf
cp GENERIC BLAH
<edit blah to comment out options SMP>
cd /usr/src
make build kernel KERNCONF=BLAH
