From d9b8d0da404cf952a425d990c37c29c166eec954 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Mon, 12 Jun 2006 12:20:09 +0100 Subject: [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 ...
