ARM: 5734/1: arm: fix compilation of entry-common.S for older CPUs
Commit 181f817eaaca4c1f introduced some new code to entry-common.S Sadly, this new code uses 'bx' instruction which is available only on ARMv5 and higher CPUs. This causes following compilation errors when building kernel for StrongARM (ARMv4): arch/arm/kernel/entry-common.S: Assembler messages: arch/arm/kernel/entry-common.S:129: Error: selected processor does not support `bx ip' arch/arm/kernel/entry-common.S:138: Error: selected processor does not support `bx ip' Fix these errors by using 'mov pc' instead of 'bx'.
