Since the clear_uuids operation doesn't send an immediate HCI command
but just sets off a timer to wait for subsequent add_uuid calls it
doesn't make sense to wait until the timer fires off to send the

The code for ip1001_config_init() was totally broken if you were not
using RGMII. Instead of returning an error code or zero it actually
returned the value in the IP1001_SPEC_CTRL_STATUS_2 register. It was
also trying to set the IP1001_APS_ON bit , but never actually wrote
back the register.
The error checking was also incorrect in both this function and the

Disabling IRQ #16
An un-wanted interrupt is generated when PCI driver switches from
MSI/MSI-X to INTx while shutting down the device. The interrupt does
not happen if MSI/MSI-X is not used on the device.
I confirmed that this problem does not happen if pcie_hp=nomsi was
specified and hotplug operation worked fine as usual.
v2: Automatically disable MSI/MSI-X against following device:
PCI bridge: Integrated Device Technology, Inc. Device 807f (rev 02)
v3: Based on the review comment, combile the if statements.
v4: Removed module parameter.
Move some code to build pciehp as a module.
Move device specific code to driver/pci/quirks.c.
v5: Drop a device specific code until getting a vendor statement.

If btrfs reads a block and finds a parent transid mismatch, it clears
the uptodate flags on the extent buffer, and the pages inside it. But
we only clear the uptodate bits in the state tree if the block straddles
more than one page.
This is from an old optimization from to reduce contention on the extent
state tree. But it is buggy because the code that retries a read from
a different copy of the block is going to find the uptodate state bits
set and skip the IO.
The end result of the bug is that we'll never actually read the good
copy (if there is one).
The fix here is to always clear the uptodate state bits, which is safe
because this code is only called when the parent transid fails.
