This narrows the scope of the apple re-POST hack added in:
drm/radeon: re-POST the asic on Apple hardware when booted via EFI
That patch prevents UVD from working on macs when booted in EFI
mode. The original patch fixed macbook2,1 systems which were
r5xx and hence have no UVD. Limit the hack to those systems to
prevent UVD breakage on newer systems.

Static checkers complain about widening the binary "not" operations here
because sectors are u64 and "(pd)->settings.size" is unsigned int.
It unintentionally clears the high 32 bits of the sector. This means
that the driver won't work for devices with over 2TB of space. Since
this is a DVD drive, we're unlikely to reach that limit, but we may as
well silence the warning.

power_supply core has the bad habit of calling our battery callbacks
from within power_supply_register(). Furthermore, if the callbacks
fail with an unhandled error code, it will skip any uevent that it
might currently process.
So if HID-core registers battery devices, an "add" uevent is generated
and the battery callbacks are called. These will gracefully fail due
to timeouts as they might still hold locks on event processing. One
could argue that this should be fixed in power_supply core, but the
least we can do is to signal ENODATA so power_supply core will just
skip the property and continue with the uevent.
This fixes a bug where "add" and "remove" uevents are skipped for
battery devices. upower is unable to track these devices and currently
needs to ignore them.
This patch also overwrites any other error code. I cannot see any reason
why we should forward protocol- or I/O-errors to the power_supply core.
We handle these errors in hid_ll_driver later, anyway, so just skip
them. power_supply core cannot do anything useful with them, anyway,
and we avoid skipping important uevents and confusing user-space.
Thanks a lot to Daniel Nicoletti for pushing and investigating
on this.

While l2cap_user callbacks are running, the whole hci_dev is locked. Even
if we would add more fine-grained locking to HCI core, it would still be
called from the non-reentrant rx work-queue and thus block the event
processing.
However, if we want to perform synchronous I/O during HID device
registration (eg., to perform device-detection), we need the HCI core
to be able to dispatch incoming data.
Therefore, we now move device-registration to a separate worker. The HCI
core can continue running and we add devices asynchronously in another
kernel thread. Device removal is synchronized and waits for the worker
to exit before calling the usual device removal functions.
If l2cap_user->remove is called before the thread registered the devices,
we set "terminate" to true and the thread will skip it. If
l2cap_user->remove is called after it, we notice this as the device
is no longer in HIDP_SESSION_PREPARING state and simply unregister the
device as we did before.
There is no new deadlock as we now call hidp_session_add_dev() with
one lock less held (the HCI lock) and it cannot itself call back into
HCI as it was called with the HCI-lock held before.
One might wonder whether this can block during device unregistration.
But we set "terminate" to true and wake the HIDP thread up _before_
unregistering the HID/input devices. Therefore, all pending HID I/O
operations are canceled. All further I/O attempts will fail with ENODEV
or EIO. So all latency we can get are few context-switches, but no
timeouts or blocking I/O waits!
This change also prepares for a long standing HID bug. All HID devices
that register power_supply devices need to be able to handle callbacks
during registration (a power_supply oddity that cannot easily be fixed).
So with this patch available, we can allow HID I/O during registration
by calling the recently introduced hid_device_io_start/stop helpers,
which currently are a no-op for bluetooth due to this locking.
Note that we cannot do the same for input devices. input-core doesn't
allow us to call input_event() asynchronously to input_register_device(),
which HID-core kindly allows (for good reasons).
Fixing input-core to allow this isn't as easy as it sounds and is,
beside simplifying HIDP, not really an improvement. Hence, we still
register input devices synchronously as we did before. Only HID devices
are registered asynchronously.

Make it explicit that the format attributes may define overlapping bit
ranges. Unfortunately this was left unspecified originally, and all the
examples show non-overlapping ranges. I don't believe this is an ABI
change, as we are defining something that was previously undefined, but
others may disagree.
The POWER8 PMU would like to define overlapping ranges, as bit ranges in
the event code have different meanings for certain events. It will also
allow us to define an overarching "event" field, that encompasses all
others.
As far as I can see perf is comfortable with this change, however I am
not sure if there are any other users of the interface.

Commit f447d56d36 introduced the
implementation of the PV apic ipi interface. But there were some
odd things (it seems none of which cause really any issue but
maybe they should be cleaned up anyway):
- xen_send_IPI_mask_allbutself (and by that xen_send_IPI_allbutself)
ignore the passed in vector and only use the CALL_FUNCTION_SINGLE
vector. While xen_send_IPI_all and xen_send_IPI_mask use the vector.
- physflat_send_IPI_allbutself is declared unnecessarily. It is never
used.
This patch tries to clean up those things.

It'd be best if we could change the type to "__s64*", but that would

As drvdata is cleared to NULL at probe failure or at removal by the

longer in each driver.
The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c. Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.
