RISC-V Fixes for 5.16-rc2

Browse Source 
I have two patches for 5.16:
 
 * A fix that allows external modules to be built against read-only
   source trees.
 * A patch to turn KVM on in the defconfigs.
 
 The second one isn't technically a fix, but it got tied up pending some
 defconfig cleanups that ended up finding some larger issues.  I figured
 it'd be better to get the config changes some more testing, but didn't
 want to hold up turning KVM on for that.
