Imapct: add a new struct member to 'struct protection_domain'
When using protection domains for dma_ops and KVM its better to know for
which subsystem it was allocated. Add a flags member to struct
protection domain for that purpose.

Impact: add a function to flush a domain id on every IOMMU
Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
|
|
Impact: save unneeded logic to add and remove domains to the list
The removal of a protection domain from the iommu_pd_list is not
necessary. Another benefit is that we save complexity because we don't
have to readd it later when the device no longer uses the domain.

Impact: change code to free pagetables from protection domains
The dma_ops_free_pagetable function can only free pagetables from
dma_ops domains. Change that to free pagetables of pure protection
domains.
