Currently attach device path takes protection domain lock followed by
dev_data lock. Most of the operations in this function is specific to
device data except pdom_attach_iommu() where it updates protection
domain structure. Hence reduce the scope of protection domain lock.
Note that this changes the locking order. Now it takes device lock
before taking doamin lock (group->mutex -> dev_data->lock ->
pdom->lock). dev_data->lock is used only in device attachment path.
So changing order is fine. It will not create any issue.
Finally move numa node assignment to pdom_attach_iommu().

Previous patch enhanced core layer to check device PASID capability and

Enhance amd_iommu_domain_alloc_user() to allocate domain with
appropriate page table based on flags parameter.
- If flags is empty then allocate domain with default page table type.
This will eventually replace ops->domain_alloc().
For UNMANAGED domain, core will call this interface with flags=0. So
AMD driver will continue to allocate V1 page table.
- If IOMMU_HWPT_ALLOC_PASID flags is passed then allocate domain with v2

Currently drivers calls iommu_paging_domain_alloc(dev) to get an
UNMANAGED domain. This is not sufficient to support PASID with
UNMANAGED domain as some HW like AMD requires certain page table type
to support PASIDs.
Also the domain_alloc_paging op only passes device as param for domain
allocation. This is not sufficient for AMD driver to decide the right
page table.
Instead of extending ops->domain_alloc_paging() it was decided to
enhance ops->domain_alloc_user() so that caller can pass various
additional flags.
Hence add iommu_paging_domain_alloc_flags() API which takes flags as
parameter. Caller can pass additional parameter to indicate type of
domain required, etc. iommu_paging_domain_alloc_flags() internally calls
appropriate callback function to allocate a domain.

If a page is mapped starting at 0 that is equal to or larger than can fit
in the current mode (number of table levels) it results in corrupting the
mapping as the following logic assumes the mode is correct for the page
size being requested.
There are two issues here, the check if the address fits within the table
uses the start address, it should use the last address to ensure that last
byte of the mapping fits within the current table mode.
The second is if the mapping is exactly the size of the full page table it
has to add another level to instead hold a single IOPTE for the large
size.
Since both corner cases require a 0 IOVA to be hit and doesn't start until
a page size of 2^48 it is unlikely to ever hit in a real system.

Fix rcuog kthread wakeup invocation from softirq context on a CPU
which has been marked offline. This can happen when new callbacks
are enqueued from a softirq on an offline CPU before it calls
rcutree_report_cpu_dead(). When this happens on NOCB configuration,
the rcuog wake-up is deferred through an IPI to an online CPU.
This is done to avoid call into the scheduler which can risk
arming the RT-bandwidth after hrtimers have been migrated out
and disabled. However, doing IPI call from softirq is not allowed
Fix this by forcing deferred rcuog wakeup through the NOCB timer
when the CPU is offline.
