Hi,
While working with the mips codebase I had to QOMify it.
I then read Igor's series "complete cpu QOMification" [1] and after some IRC
chat I suggested Igor to rebase his series on mine to avoid code moving
forward then back.
Since most of Igor's series is reviewed I'm posting this a week before 2.11.
I'm not sure about the TypeInfo.abstract change so it is RFC.
Also I couldn't test it with KVM.
Regards,
Phil.

Igor Mammedov (2):
mips: MIPSCPU model subclasses
mips: replace cpu_mips_init() with cpu_generic_init()
Philippe Mathieu-Daudé (6):
mips: move hw/mips/cputimer.c to target/mips/
mips: introduce internal.h and cleanup cpu.h
mips: split cpu_mips_realize_env() out of cpu_mips_init()
mips: call cpu_mips_realize_env() from mips_cpu_realizefn()
mips: now than MIPSCPU is QOMified, mark it abstract
mips: update mips_cpu_list() to use object_class_get_list()

This timer is a required part of the MIPS32/MIPS64 System Control coprocessor
(CP0). Moving it with the other architecture related files will allow an opaque
use of CPUMIPSState* in the next commit (introduce "internal.h").
also remove it from 'user' targets, remove an unnecessary include.

no logical change, only code movement (and fix a comment typo).

Tested in TCG mode (boots debian mips/mips64 kernel with different cpu types),
and new CPU leaf types show up on QOM tree as expected (QOMifycation is done as expected)
and '-cpu help' also works as expected,
so with checkpatch issues fixed you may add to patches my

After asking confirmation on IRC these 3 checkpatch issues are false
positives, and I'm not fluent in Perl to fix it, so I'll add a comment
about it in the next series cover.

ok thanks for the testing!
I'll wait to see if there is some KVM feedback from imgtec folks before

I've used scripts/qmp/qom-* scripts for testing which use QMP,
but QOM tree that both use is the same so there shouldn't be any difference.

I'm waiting 2.11 officially announced open to send it which should be
tomorrow, in the meaning time it is available in my git repository at:

A sanity check of your branch doesn't reveal any obvious regressions
when booting a Malta KVM guest kernel with KVM.
