Google Juice:

I've written up a page describing how to deal with this compile error:

`CONFIG_X86_L1_CACHE_SHIFT' undeclared here (not in a function)

under Mandrake 9.0 or other Mandrake 9.x series distros.

I wrote the page because I spent quite a while last night searching and found lots of references to the problem, but none to the solution. When I figured it out, I thought it'd be a good idea to add the solution to the search results.
