Assembly entry/return abstraction change didn't add asmmacro.h include statement to coprocessor.S, resulting in references to undefined macros abi_entry and abi_ret on cores that define XTENSA_HAVE_COPROCESSORS. Fix that by including asm/asmmacro.h from the coprocessor.S.

This seems to be fixing commit d6d5f19e21d9 "xtensa: abstract 'entry' and 'retw' in assembly code" so it wouldn't be needed for any stable branches.

That's correct.
