This patch may fix two issues:
First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into
defer list to delay execution, but link io will be actively scheduled to
run by calling io_queue_sqe.
Second, when multiple LINK_IOs are inserted together with defer_list,
the LINK_IO is no longer keep order.

Commit bd11b3a391 ("io_uring: don't use iov_iter_advance() for fixed
buffers") introduced an optimization to avoid using the slow
iov_iter_advance by manually populating the iov_iter iterator in some
cases.
However, the computation of the iterator count field was erroneous: The
first bvec was always accounted for an extent of page size even if the
bvec length was smaller.
In consequence, some I/O operations on fixed buffers were unable to
operate on the full extent of the buffer, consistently skipping some
bytes at the end of it.

quirk_reset_lenovo_thinkpad_50_nvgpu() resets NVIDIA GPUs to work around
an apparent BIOS defect. It previously used pci_reset_function(), and
the available method was a bus reset, which was fine because there was
only one function on the bus. After b516ea586d ("PCI: Enable NVIDIA
HDA controllers"), there are now two functions (the HDA controller and
the GPU itself) on the bus, so the reset fails.
Use pci_reset_bus() explicitly instead of pci_reset_function() since it's
OK to reset both devices.

We have done this for pre-GFX10 asics, but GFX10 did not pick up the
new change. The below is the commit message for that change.
This is recommended by HW designers. Previously when it was set to 1,
the PDE walk error in VM fault will be treated as
PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT.
As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly.
The above behavior is kind of abnormal. Furthermore, the
PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs
and it never made it way to production. Therefore, we should set it to 0.
