Also worth noting is the one other outstanding bug, where the time-related

Hi Linus,
Please pull two more powerpc fixes for 5.7. These are both regressions with
small "obviously correct" fixes.

Sure thing, I spotted
H_SVM_INIT_DONE incorrectly assumes that the Ultravisor has explicitly
called H_SVM_PAGE_IN for all secure pages. These GFNs continue to be
normal GFNs associated with normal PFNs; when infact, these GFNs should
have been secure GFNs associated with device PFNs.
Move all the PFN associated with
During the life of SVM, its GFNs can transition from secure to shared
state and vice-versa. Since the kernel does not track GFNs that are
shared, it is not possible to disambiguate a shared GFN from a GFN whose
PFN has not yet been migrated to a device-PFN.
The ability to identify a shared GFN is
From: Laurent Dufour
When a memory slot is hot plugged to a SVM, GFNs associated with that
memory slot automatically default to secure GFN. Hence migrate the
PFNs associated with these GFNs to device-PFNs.
uv_migrate_mem_slot() is called to achieve that. It will not call
UV_PAGE_IN since this
Drop the redundant local_irq_save/restore() from adb_iop_start() because
the caller has to do it anyway. This is the pattern used in via-macii.

device addresses can be updated. When the list is empty, disable SRQ

This patch series migrates the non-migrate pages of a SVM.
This is required when the UV calls H_SVM_INIT_DONE, and

This algorithm is slightly shorter and avoids the surprising
adb_iop_start() call in adb_iop_poll().

In the present algorithm, the 'idle' state transition does not take
place until there's a bus timeout. Once idle, the driver does not
automatically proceed with the next request.
Change the algorithm so that queued ADB requests will be sent as soon as
the driver becomes idle. This is to take
The adb-iop driver was never finished. Some deficiencies have become
apparent over the years. For example,

- SRQ autopoll list cannot be changed
- Some bugs were found by inspection

On leaving the 'sending' state, proceed to the 'idle' state if no reply is
expected. Drop redundant test for adb_iop_state == sending && current_req.
