Can you make this function memslot_valid_for_gpte(struct kvm_memory_slot

slot && !(slot->flags & KVM_MEMSLOT_INVALID) &&

Since kmemdup can be failed in memory pressure,
return value should be checked and return -ENOMEM.

There seems to be a new class of interrupt controller out there whose
sole purpose (apart from making everybody's life a nightmare) is to
turn wired interrupts into MSIs.
Instead of considering that the MSIs allocated to a device are for the
direct use of that device, we can turn this set of MSIs
As we're going to have multiple paths to allocate/free the
platform-msi private data, factor this out into separate
utility functions.

MSIs for a given device are normally all allocated in one go.
Make sure the internal code can allocate them one at a time
if required.

The .prepare callbacks are so far only called from msi_domain_alloc_irqs.
In order to reuse that code, split that code and create a
msi_domain_prepare_irqs function that the existing code can call into.

We almost have all the needed bits to be able to create a irq domain
on top of a MSI domain.
For this, we enable a few things:
- the virq is stored in the msi_desc
- device, msi_alloc_info and domain-specific data
are stored in the platform_pric_data structure
- we introduce a new API for platfo
We are soon going to need the MSI layer to call into the domain
allocators. Instead of open coding this, make the standard
irq_domain_alloc_irqs_recursive function available to the MSI
layer.

In order to demonstrate how to put together a wire/MSI bridge,
add a dummy driver that doesn't do anything at all, except
for allocating interrupts.
It comes together with an even more stupid client driver that
allocates an interrupt and dump the hierarchy of that interrupt.

In theory it does. In practice it's only used

This is the value that matters. It would appear to be -ENOKEY and would be in
