From 10146801e8b960d7473e350b60458d9d5a2be1cf Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Thu, 19 Jul 2007 01:49:15 -0700 Subject: m68knommu: remove is_in_rom() function Remove is_in_rom() function. It doesn't actually serve the purpose it was intended to. If you look at the use of it _access_ok() (which is the only use of it) then it is obvious that most of memory is marked as access_ok. No point having is_in_rom() then, so remove it.
