ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+ 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.

ARM: 8314/1: replace PROCINFO embedded branch with relative offset This patch replaces the 'branch to setup()' instructions embedded in the PROCINFO structs with the offset to that setup function relative to the base of the struct. This preserves the position independent nature of that field, but uses a data item rather than an instruction. This is mainly done to prevent linker failures on large kernels, where the setup function is out of reach for the branch.
