This is code only built for 32-bit sparc :-) My local script confused me, it translated sparc64 into ARCH=sparc for me, where it turns out the defconfig == sparc32_defconfig, so I was actually building 32 bit. Sorry about that. Turns out I also saw this on 32-bit sparc defconfig, which is hardly surprising given the two .configs are exactly the same ;-) Ian. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

With my patch applied I don't see any sparse warnings for these lines of pcic.c, although there are others: CHECK /local/scratch/ianc/devel/kernels/linux-2.6/arch/sparc/kernel/pcic.c arch/sparc/kernel/pcic.c:163:14: warning: symbol 'pcic_regs' was not declared.
