Hi,

Sparse detected a problem with n270 CPU definition, I think
        .ext_features = CPUID_EXT_MONITOR |
            CPUID_EXT_SSE3 /* PNI */, CPUID_EXT_SSSE3,
            /* Missing: CPUID_EXT_DSCPL | CPUID_EXT_EST |
             * CPUID_EXT_TM2 | CPUID_EXT_XTPR */
should be:
        .ext_features = CPUID_EXT_MONITOR |
            CPUID_EXT_SSE3 /* PNI */ | CPUID_EXT_SSSE3,
            /* Missing: CPUID_EXT_DSCPL | CPUID_EXT_EST |
             * CPUID_EXT_TM2 | CPUID_EXT_XTPR */

SSSE3 is indeed supported by n270 according to Intel documentation

Thanks, good catch!  I had only tested n270 in user mode, that's why
it didn't blow up.

Cheers
