Description Martin Ettl 2009-03-29 00:09:38 UTC 
Hi,

i checked the sources with a static code analysis tool and found a few issues:

[linux-2.6.29/arch/x86/kernel/cpu/intel_cacheinfo.c:721]: (error) Overlapping data buffer buf
[linux-2.6.29/arch/x86/kernel/cpu/intel_cacheinfo.c:723]: (error) Overlapping data buffer buf
[linux-2.6.29/arch/x86/kernel/cpu/intel_cacheinfo.c:727]: (error) Overlapping data buffer buf


Line 721: ret += sprintf(buf, "%sEntry: %d\n", buf, i);
At line 723 and 727 the same issue happens!

Best regards

Ettl Martin
