It could actually be something as "simple" as the organization
of the functions in the image. Would you also send along the
portion of the System.map that covers these kernel address
ranges? There is only one additional user space TLB, which
is probably the C library, all of the rest are kernel ones.
For example, what functions are in the range of 0xc009c00,
0xc009d000, 0xc009e000, and in the 0xc0003000
pages for your 2.4 kernel?
Thanks.
