Move _irqfd_resampler and _irqfd struct declarations in a new
public header: kvm_irqfd.h. They are respectively renamed into
kvm_kernel_irqfd_resampler and kvm_kernel_irqfd. Those datatypes
will be used by architecture specific code, in the context of
IRQ bypass manager integration.
This series transforms irqfd into an IRQ bypass consumer and
introduce the infrastructure shared by Intel posted-interrupts
and ARM forwarded IRQ series.
The bypass manager gets compiled for x86 and arm/arm64 when
KVM is used. A new kvm_irqfd.h header is created to externalize
some irqfd

This series allows to set ARM IRQ forwarding between a VFIO platform
device physical IRQ and a guest virtual IRQ. The link is coordinated
by the IRQ bypass manager.
The principle is the VFIO platform driver registers an IRQ bypass producer

Add a new forwarded flag in vfio_platform_irq. In case the IRQ
is forwarded, the VFIO platform IRQ handler does not need to
disable the IRQ anymore.
When setting the IRQ handler we now also test the forwarded state. In
case the IRQ is forwarded we select the vfio_irq_handler.

This function returns whether the IRQ is active at irqchip level or
VFIO masked. If either is true, it is considered the IRQ is active.
Currently there is no way to differentiate userspace masked IRQ from
automasked IRQ. There might be false detection of activity. However

So far, the only use of the HW interrupt facility was the timer,
implying that the active state is context-switched for each vcpu,
as the device is is shared across all vcpus.
This does not work for a device that has been assigned to a VM,
as the guest is entierely in control
A single handler now is registered whatever the use case: automasked
or not. A function pointer is set according to the wished behavior
and the handler calls this function.
The irq lock is taken/released in the root handler. eventfd_signal can
be called in regions not allowed to sleep.

Currently mxs-auart doesn't care correctly about the baud rate divisor.
According to reference manual the baud rate divisor must be between
0x00EC and 0x003FFFC0. So calculate the possible baud rate range

THP page and the get refcount in madvise_hwpoison is against the single
4KB page instead of the logic in get_hwpoison_page.

current code doesn't release the refcount of head page if the THP is not
supported to be injected wrt hwpoison filter.
Fix it by reducing the
Introduce put_hwpoison_page to put refcount for memory
