Pull MIPS updates from Paul Burton:
- Support for the MIPSr6 MemoryMapID register & Global INValidate TLB
(GINVT) instructions, allowing for more efficient TLB maintenance
when running on a CPU such as the I6500 that supports these.
- Enable huge page support for MIPS64r6.
- Optimize post-DMA cache sync by removing that code entirely for
kernel configurations in which we know it won't be needed.
- The number of pages allocated for interrupt stacks is now calculated
correctly, where before we would wastefully allocate too much memory
in some configurations.
- The ath79 platform migrates to devicetree.
- The bcm47xx platform sees fixes for the Buffalo WHR-G54S board.
- The ingenic/jz4740 platform gains support for appended devicetrees.
- The cavium_octeon, lantiq, loongson32 & sgi-ip27 platforms all see
cleanups as do various pieces of core architecture code.

The separate GPHY Firmware loader driver is not used any more, the GPHY
firmware is now loaded by the GSWIP switch driver which also makes use
of the GPHY.
Remove the old unused GPHY firmware loader driver.
The GPHY firmware is useless without an Ethernet and switch driver, it
should not harm if loading this does not work for system using an old
device tree.
I am not aware of any vendor separating the device tree from the kernel
binary, it should be ok to remove this.
The code and the functionality form this separate GPHY firmware loader
was added to the gswip driver in commit 14fceff4771e ("net: dsa: Add
Lantiq / Intel DSA driver for vrx200")

Similar to commit bcf3f1752a62 ("parisc: Hide Diva-built-in serial aux and
graphics card") it's better to hide the built-in serial AUX port at bootup.
When not hiding the port, the Linux serial driver will try to manage this port
and fails on a A500 server like this:
serial 0000:00:05.0: enabling device (0000 -> 0003)
serial 0000:00:05.0: enabling SERR and PARITY (0003 -> 0143)
0000:00:05.0: ttyS3 at MMIO 0xfffffffff8005000 (irq = 71, base_baud = 115200) is a 16550A
serial 0000:00:05.0: Couldn't register serial port 0, irq 71, type 2, error -28

The dasd_eckd_restore_device() function calls dasd_generic_read_dev_chars
with a temporary buffer on the stack. With CONFIG_VMAP_STACK=y this is
a vmalloc address but dasd_generic_restore_device() uses the address of
the buffer as I/O address. Circumvent this by using the already allocated
cqr->data buffer for the RDC data.

it in the other places of code that make these checks.
(Why isn't ccw_head fully removed? Well, because this
way some longs lines don't have to be reflowed.)

The routine ccwchain_calc_length() is tasked with looking at a
channel program, seeing how many CCWs are chained together by
the presence of the Chain-Command flag, and returning a count
to the caller.
Previously, it also considered a Transfer-in-Channel CCW as being
an appropriate mechanism for chaining. The problem at the time
was that the TIC CCW will almost certainly not go to the next CCW
in memory (because the CC flag would be sufficient), and so
advancing to the next 8 bytes will cause us to read potentially
invalid memory. So that comparison was removed, and the target
of the TIC is processed as a new chain.
This is fine when a TIC goes to a new chain (consider a NOP+TIC to
a channel program that is being redriven), but there is another
scenario where this falls apart. A TIC can be used to "rewind"
a channel program, for example to find a particular record on a
disk with various orientation CCWs. In this case, we DO want to
consider the memory after the TIC since the TIC will be skipped
once the requested criteria is met. This is due to the Status
Modifier presented by the device, though software doesn't need to
operate on it beyond understanding the behavior change of how the
channel program is executed.
So to handle this, we will re-introduce the check for a TIC CCW
but limit it by examining the target of the TIC. If the TIC
doesn't go back into the current chain, then current behavior
applies; we should stop counting CCWs and let the target of the
TIC be handled as a new chain. But, if the TIC DOES go back into
the current chain, then we need to keep looking at the memory after
the TIC for when the channel breaks out of the TIC loop. We can't
use tic_target_chain_exists() because the chain in question hasn't
been built yet, so we will redefine that comparison with some small
functions to make it more readable and to permit refactoring later.

Libudev relies on having a subsystem link for non-root devices. To
avoid libudev (and potentially other userspace tools) choking on the
matrix device let us introduce a matrix bus and with it the matrix
bus subsytem. Also make the matrix device reside within the matrix
bus.
Doing this we remove the forced link from the matrix device to the
vfio_ap driver and the device_type we do not need anymore.
Since the associated matrix driver is not the vfio_ap driver any more,
we have to change the search for the devices on the vfio_ap driver in
the function vfio_ap_verify_queue_reserved.

Prior to dma unmap/free operations the ism driver tries to ensure
that the memory is no longer accessed by the HW. When errors
during deregistration of memory regions from the HW occur the ism
driver will not unmap/free this memory.
When we receive notification from the hypervisor that a PCI function
has been detached we can no longer access the device and would never
unmap/free these memory regions which led to complaints by the DMA
debug API.
Treat this kind of errors during the deregistration of memory regions
from the HW as success since it is already ensured that the memory
is no longer accessed by HW.

When an alternate driver (vfio-ap) has bound an ap queue and this
binding is revised the ap queue device is in an intermittent
state not bound to any driver. The internal state variable
covered this with the state AP_STATE_BORKED which is also used to
reflect broken devices. When now an ap bus scan runs such a
device is destroyed and on the next scan reconstructed.
So a stress test with high frequency switching the queue driver
between the default and the vfio-ap driver hit this gap and the
queue was removed until the next ap bus scan. This fix now
introduces another state for the in-between condition for a queue
momentary not bound to a driver and so the ap bus scan function
skips this device instead of removing it.
Also some very slight but maybe helpful debug feature messages
come with this patch - in particular a message showing that a
broken card/queue device will get removed.

The cavium/zip implementation of the deflate compression algorithm is
incorrectly being registered under the generic driver name, which
prevents the generic implementation from being registered with the
crypto API when CONFIG_CRYPTO_DEV_CAVIUM_ZIP=y. Similarly the lzs
algorithm (which does not currently have a generic implementation...)
is incorrectly being registered as lzs-generic.
Fix the naming collision by adding a suffix "-cavium" to the
cra_driver_name of the cavium/zip algorithms.

buffers coming directly from user is incorrect, since they are
not guaranteed to be DMAable.

(split key generation, respectively key hashing).

The current content of some of the driver messages and the way that they
are issued results in some confusion, especially in the area of the PSP
as it relates to SEV support. If SEV is not supported, a message is issued
that says "psp initialization failed." This makes it seem like there was
a problem, when in fact, the PSP support is just disabled if SEV is not
supported.
Update the driver to check SEV support a bit earlier and issue a debug-
level message if SEV is not supported, followed by a debug-level message
that the PSP is disabled. This way you will only see PSP messages if SEV
is supported or if debug information is desired. Also, remove the overall
"enabled" and "disabled" messages for the driver and rely on the CCP and
PSP support to issue component-specific messages.

Driver was relying on an older DPIO API, which provided a CPU-affine DPIO
in case it was called with preemption disabled.
Since this is no longer the case, save the CPU-affine DPIO in per-cpu
private structure during setup and further use it on the hot path.
Note that preemption is no longer disabled while trying to enqueue an
FD. Thus it might be possible to run the enqueue on a different CPU
(due to migration, when in process context), however this wouldn't be a
functionality issue.
Since we allow for all cores to enqueue, we take care of data
structures setup to handle the case when number of (Rx, Tx) queue pairs
is smaller than number of cores.

Allocatable devices can be acquired by drivers on the fsl-mc bus using
the fsl_mc_portal_allocate or fsl_mc_object_allocate functions. Add a
device link between the consumer device and the supplier device so that
proper resource management is achieved.
Also, adding a link between these devices ensures that a proper unbind
order is respected (ie before the supplier device is unbound from its
respective driver all consumer devices will be notified and unbound
first).

Automatically add a device link between the actual device requesting the
dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.
For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.
Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).
