>Description:
undefined reference to `uvm_mremap' in /usr/lkm/compat_linux.o.

>How-To-Repeat:
# /sbin/modload /usr/lkm/compat_linux.o
/usr/lkm/compat_linux.o: In function `linux_sys_mremap':
: undefined reference to `uvm_mremap'
modload can't prelink `/usr/lkm/compat_linux.o' creating `/usr/lkm/compat_linux'

$ nm /usr/lkm/compat_linux.o | grep uvm_mremap
     U uvm_mremap

$ nm /usr/lkm/netbsd | grep -c uvm_mremap
