Subject: cpu: Replace do_interrupt() by CPUClass::do_interrupt method
X-Git-Tag: v1.5.0-rc0~471^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=97a8ea5a3ae7938cb54fd4dc19d3a413024bc6c0;p=thirdparty%2Fqemu.git

cpu: Replace do_interrupt() by CPUClass::do_interrupt method

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.
