Hrmmmm... Our output is slightly different... but, it could
be the /proc version:

A couple things stand out... the obvious understanding of the cache.
In mine cache information is in the platform string.
My Bogomips is slightly lower..... and the Kernel unaligned acc Pointer is >null<..
Yours: (pc=fffffc00004fe0ec,va=fffffc000af0e326)
user unaligned acc : 112 (pc=120002ab0,va=12001be2c)
