From 574e2b5111e13827da501771b27d92e6e3f2e3d7 Mon Sep 17 00:00:00 2001 From: Victor Kamensky Date: Tue, 27 Aug 2013 22:41:57 -0700 Subject: ARM: signal: sigreturn_codes should be endian neutral to work in BE8 In case of BE8 kernel data is in BE order whereas code stays in LE order. Move sigreturn_codes to separate .S file and use proper assembler mnemonics for these code snippets. In this case compiler will take care of proper instructions byteswaps for BE8 case. Change assumes that sufficiently Thumb-capable tools are used to build kernel. Problem was discovered during ltp testing of BE system: all rt_sig* tests failed. Tested against the same tests in both BE and LE modes.
