Russell King 124047a81e ARM: net: bpf: avoid 'bx' instruction on non-Thumb capable CPUs 
commit e906248182 upstream.

Avoid the 'bx' instruction on CPUs that have no support for Thumb and
thus do not implement this instruction by moving the generation of this
opcode to a separate function that selects between:

	bx	reg

and

	mov	pc, reg

according to the capabilities of the CPU.
