parent[MIPS] Consolidate definitions of pfn_valid in one file. (diff)
[MIPS] Drop 0 definition for kern_addr_valid
kern_addr_valid is currently only being used in kmem_ptr_validate which is making some vague attempt at verfying the validity of an address. Only IA-64, PARISC and x86-64 actually make some actual effort to verify the validity of the pointer. Most architecture definitions of kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM on i386 and MIPS even as 0; the 0-definition will result in kmem_ptr_validate always failing which in turn will cause d_validate to always fail. d_validate's only two users are smbfs and ncpfs, so the 0 definition ended breaking those ...
