Cover letter [PATCH 0/2] x86: Use "er" asm constriant for add/sub

The x86 instruction set only supports 32bit signed immediate values for add/sub.
Replace the "ir" constraint with "er" to avoid build errors.

Found by a patch that added used mul_u64_add_u64_div_u64() to do a rounding divide by 2^32 (perhaps not the best way to do this).

A quick grep only found one other affected file.
