Yeah:
https://git.kernel.org/cgit/linux/kernel/git/linusw/linux-integrator.git/log/?h=apq8060-dragonboard-ethernet

The apq8060-dragonboard branch is clean (just necessary boot fixes,
the flag fixes and the revert), gives the right IRQs:
https://git.kernel.org/cgit/linux/kernel/git/linusw/linux-integrator.git/log/?h=apq8060-dragonboard

The webpage gives the details of how I build, my Makefile and
initramfs.cpio etc if you want:

Yes. Doesn' appear anymore in v4.8-rc1

Yes AFAICT.

pm8058 -> tlmm hwirq 88 -> GIC hwirq 16
