From 206582c3161f165f5bf49ececa962c5f95fdf0a3 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 13 Jan 2010 18:45:12 +0900 Subject: sh: Make all PxSEGADDR() calls fatal for non-legacy configs. This stubs out all of the PxSEGADDR() wrappers for non-legacy code. 29-bit will continue to work with these, while 32-bit code will now blow up on compile rather than at runtime. The vast majority of the in-tree offenders are gone, with the only remaining culprits being unable to support 32-bit mode. Hopefully this will prevent anyone from ever using these again.
