Hwpoison allows to filter pages by memory cgroup ino. To ahieve that, it
calls try_get_mem_cgroup_from_page(), then mem_cgroup_css(), and finally
cgroup_ino() on the cgroup returned. This looks bulky. Since in the next
patch I need to get the ino of the memory cgroup a page is charged to

Hi,
so, the bus recovery patches look fine to me in general.
It is only this one question left which I always had with bus recovery.
Maybe you guys can join me thinking about it.

If the hypervisor supports MSR based access to the APIC registers
(EOI, TPR and ICR), implement the MSR based access.

vga_set_legacy_decoding() is defined in drivers/gpu/vga/vgaarb.c,
which is only compiled with CONFIG_VGA_ARB. A caller would
therefore get an undefined symbol if the VGA arbiter is not
enabled.

Some gpio controllers are capable of programming its pins' active-low
state. Let's add this new gpio_chip function for such cases and use it
in gpiolib.
When set_active_low() is implemented, we no longer need to do soft flips
on values from non-raw get functions.

If VFIO VGA access is disabled for the user, either by CONFIG option
or module parameter, we can often opt-out of VGA arbitration. We can
do this when PCI bridge control of VGA routing is possible. This
means that we must have a parent bridge and there must only be a
single VGA device below that
This copies the same support from pci-stub for exactly the same
purpose, enabling a set of PCI IDs to be automatically added to the
driver's dynamic ID table at module load time. The code here is
pretty simple and both vfio-pci and pci-stub are fairly unique in
being meta drivers, capable of
Add a module option so that we don't require a CONFIG change and
kernel rebuild to disable VGA support. Not only can VGA support be
troublesome in itself, but by disabling it we can reduce the impact
to host devices by doing a VGA arbitration opt-out.

As indicated in the comment, this is not entirely uncommon and

We can save some power by putting devices that are bound to vfio-pci
but not in use by the user in the D3hot power state. Devices get
woken into D0 when opened by the user. Resets return the device to
D0, so we need to re-apply the low power state after a bus reset.
It's tempting to try to use
v2:
- Incorporate comments from Bandan and Bjorn for vfio-pci.ids option
- Include necessary vgaarb change, already Ack'd by Dave
- Rebase on top of my current next branch
- Rename D3 disable parameter
There are really 3 separate features added in this series, the first
is to opt-out VGA

On a MIPS Malta board, tons of fifo underflow errors have been observed
when using u-boot as bootloader instead of YAMON. The reason for that
is that YAMON used to set the pcnet device to SRAM mode but u-boot does
not. As a result, the default Tx threshold (64 bytes) is now too small to
