[PATCH v5 0/7] Improve SRIOV VRAM provisioning

[Matthew Auld]

Support non-contig VRAM for pinned kernel objects. Main current usecase is
when provisioning VRAM for SRIOV usecase (final patch). Currently we are
artificially limited to using contig VRAM, however the allocations here are
very large and the contig restriction can result in failing to provision
the VF, even when there is enough free space (we just need at least 2M
pages).

v2:
 - Various fixes for CI reported issues.
v3:
 - suspend/resume and various other fixes.
v4:
 - drop one bogus assert.
 - rebase on the newly merged apply-to-pinned infra.
v5:
 - rebase on newly merged dma-unmap on unplug, which interacts with
   the pinned lists.
