Sorry Minchan, I should have said this the first time around. I ran
into this issue before with CRYTPO vs CRYPTO=y. ZCACHE is a bool where
ZSMALLOC is a tristate. It is not sufficient for ZSMALLOC to be set; it
_must_ be builtin, otherwise you get linker errors.

The dependency should be ZSMALLOC=y.

Thanks,
Seth
