[Qemu-devel] [PATCH v3 03/35] translate-all: Move tcg_handle_interrupt() to -common

[Peter Crosthwaite <crosthwaitepeter@gmail.com>]

Move this function to common code. It has no arch specific
dependencies. Prepares support for multi-arch where the translate-all
interface needs to be virtualised. One less thing to virtualise.
