Architecture: sparc
Machine: sparc
>Description:
Try and build a sparc kernel with only the stuff required by a Sun4C
system.  This fails with:

cc1: warnings being treated as errors
/external/usr/src/sys/arch/sparc/sparc/pmap.c: In function 'ctx_alloc':
/external/usr/src/sys/arch/sparc/sparc/pmap.c:2089: warning: unused variable 'cpi'
/external/usr/src/sys/arch/sparc/sparc/pmap.c: In function 'ctx_free':
/external/usr/src/sys/arch/sparc/sparc/pmap.c:2256: warning: unused variable 'cpi'

>How-To-Repeat:
Build -current kernel with custom config for Sun4C.
