From 8a13c4f972e6c107d8cff54de647544c00e25b41 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 11 Oct 2007 13:36:52 -0500 Subject: [POWERPC] Use PAGE_OFFSET to tell if an address is user/kernel in SW TLB handlers Move to using PAGE_OFFSET instead of TASK_SIZE or KERNELBASE value on 6xx/40x/44x/fsl-booke to determine if the faulting address is a kernel or user space address. This mimics how the macro is_kernel_addr() works.
