ARM: 8322/1: keep .text and .fixup regions closer together 2015-03-29T22:11:56+00:00 Ard Biesheuvel ard.biesheuvel@linaro.org 2015-03-24T09:41:09+00:00 c4a84ae39b4a5bdf609c0001e14207aa731aab30 This moves all fixup snippets to the .text.fixup section, which is a special section that gets emitted along with the .text section for each input object file, i.e., the snippets are kept much closer to the code they refer to, which helps prevent linker failure on large kernels.

ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+ 2014-07-18T11:29:04+00:00 Russell King rmk+kernel@arm.linux.org.uk 2014-06-30T15:29:12+00:00 6ebbf2ce437b33022d30badd49dc94d33ecfa498 ARMv6 and greater introduced a new instruction ("bx") which can be used to return from function calls. Recent CPUs perform better when the "bx lr" instruction is used rather than the "mov pc, lr" instruction, and this sequence is strongly recommended to be used by the ARM architecture manual (section A.4.1.1). We provide a new macro "ret" with all its variants for the condition code which will resolve to the appropriate instruction. Rather than doing this piecemeal, and miss some instances, change all the "mov pc" instances to use the new macro, with the exception of the "movs" instruction and the kprobes code. This allows us to detect the "mov pc, lr" case and fix it up - and also gives us the possibility of deploying this for other registers depending on the CPU selection.
