Please remove spinlock_enter() and spinlock_exit() from OsdSynch.c and 
retry.

rm -rf /usr/src/sys/<ARCH>/compile/GENERIC
cd /usr/src/sys/<ARCH>/conf
config GENERIC
cd ../compile/GENERIC
make depend
make
make install

Once that is done, you can just repeat:

cd /usr/src/sys/<ARCH>/compile/GENERIC
make
make install

if only one or two files are changed.  It is not always safe but it 
usually works.
