Testcase "Parsing of all PMU events from sysfs" parse events for
all PMUs, and not just cpu. In case of powerpc, the PowerVM
environment supports events from hv_24x7 and hv_gpci PMU which
is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/

Trivially migrate to the ops->blocked_domain for the existing global
static.

Since the IDENTITY and BLOCKED behaviors were moved to global statics all
that remains is the paging domain. Rename to
apple_dart_attach_dev_paging() and remove the left over type check.

Following the pattern of identity domains, just assign the BLOCKED domain

static directly.
Update powerpc to use the new scheme and remove its empty domain_alloc

In many cases the dev argument will now be !NULL so we should use it to

This flag just caches if the IO page size is larger than the CPU

dart would like to not support paging domains at all if the IO page size

Continue converting drivers to the new interface. Introduce
ops->blocked_domain to hold the global static BLOCKED domain and convert

This makes it trivial for dart and iommufd to convert over to

The global static should pre-define the type and the NOP free function can

Hi Ariel,
I'm sorry about the way I handled your patch. I should have spent more time
working with you to develop your patch.
I agree that the Reported-by tag doesn't properly reflect the contribution you
