Once an MDIO read transaction is initiated, we must read back the data
register within 16 MDC cycles after the transaction completes. Outside
of this window, reads may return corrupt data.
Therefore, disable local interrupts in the critical section, to
maximize the probability that we can satisfy this requirement.

uhid has to run hid_add_device() from workqueue context while allowing
parallel use of the userspace API (which is protected with ->devlock).
But hid_add_device() can fail. Currently, that is handled by immediately
destroying the associated HID device, without using ->devlock - but if
there are concurrent requests from userspace, that's wrong and leads to
NULL dereferences and/or memory corruption (via use-after-free).
Fix it by leaving the HID device as-is in the worker. We can clean it up
later, either in the UHID_DESTROY command handler or in the ->release()
handler.

On a setup with KSZ9131 and MACB drivers it happens on suspend path, from
time to time, that the PHY interrupt arrives after PHY and MACB were
suspended (PHY via genphy_suspend(), MACB via macb_suspend()). In this
case the phy_read() at the beginning of kszphy_handle_interrupt() will
fail (as MACB driver is suspended at this time) leading to phy_error()
being called and a stack trace being displayed on console. To solve this
.suspend/.resume functions for all KSZ devices implementing
.handle_interrupt were replaced with kszphy_suspend()/kszphy_resume()
which disable/enable interrupt before/after calling
genphy_suspend()/genphy_resume().
The fix has been adapted for all KSZ devices which implements
.handle_interrupt but it has been tested only on KSZ9131.

Both versions of the CPSW driver declare a CPSW_HEADROOM_NA macro that
takes NET_IP_ALIGN into account, but fail to use it appropriately when
storing incoming packets in memory. This results in the IPv4 source and
destination addresses to appear misaligned in memory, which causes
aligment faults that need to be fixed up in software.
So let's switch from CPSW_HEADROOM to CPSW_HEADROOM_NA where needed.
This gets rid of any alignment faults on the RX path on a Beaglebone
White.

With previous changes to make the driver handle the TX ring size more
correctly, the default TX ring size of 64 appears to significantly
bottleneck TX performance to around 600 Mbps on a 1 Gbps link on ZynqMP.
Increasing this to 128 seems to bring performance up to near line rate and
shouldn't cause excess bufferbloat (this driver doesn't yet support modern
byte-based queue management).

Network driver documentation indicates we should be avoiding returning
NETDEV_TX_BUSY from ndo_start_xmit in normal cases, since it requires
the packets to be requeued. Instead the queue should be stopped after
a packet is added to the TX ring when there may not be enough room for an
additional one. Also, when TX ring entries are completed, we should only
wake the queue if we know there is room for another full maximally
fragmented packet.
Print a warning if there is insufficient space at the start of start_xmit,
since this should no longer happen.
Combined with increasing the default TX ring size (in a subsequent
patch), this appears to recover the TX performance lost by previous changes
to actually manage the TX ring state properly.

The check for the number of available TX ring slots was off by 1 since a

The check for whether a TX ring slot was available was incorrect,
since a slot which had been loaded with transmit data but the device had
not started transmitting would be treated as available, potentially
causing non-transmitted slots to be overwritten. The control field in
the descriptor should be checked, rather than the status field (which may
only be updated when the device completes the entry).

In some cases where the Xilinx Ethernet core was used in 1000Base-X or
SGMII modes, which use the internal PCS/PMA PHY, and the MGT
transceiver clock source for the PCS was not running at the time the
FPGA logic was loaded, the core would come up in a state where the
PCS could not be found on the MDIO bus. To fix this, the Ethernet core
(including the PCS) should be reset after enabling the clocks, prior to
attempting to access the PCS using of_mdio_find_device.

When resetting the device, wait for the PhyRstCmplt bit to be set
in the interrupt status register before continuing initialization, to
ensure that the core is actually ready. When using an external PHY, this
also ensures we do not start trying to access the PHY while it is still
in reset. The PHY reset is initiated by the core reset which is
triggered just above, but remains asserted for 5ms after the core is
reset according to the documentation.
The MgtRdy bit could also be waited for, but unfortunately when using
7-series devices, the bit does not appear to work as documented (it
seems to behave as some sort of link state indication and not just an
indication the transceiver is ready) so it can't really be relied on for
this purpose.

Now that have_bytes is never modified, we can simplify this function.
First, we move the check for negative entropy_count to be first. That
ensures that subsequent reads of this will be non-negative. Then,
have_bytes and ibytes can be folded into their one use site in the
min_t() function.

This is an old driver that has seen a lot of different eras of kernel
coding style. In an effort to make it easier to code for, unify the
coding style around the current norm, by accepting some of -- but
certainly not all of -- the suggestions from clang-format. This should
remove ambiguity in coding style, especially with regards to spacing,
when code is being changed or amended. Consequently it also makes code
review easier on the eyes, following one uniform style rather than
several.

This gets rid of another abstraction we no longer need. It would be nice
if we could instead make pool an array rather than a pointer, but the
latent entropy plugin won't be able to do its magic in that case. So
instead we put all accesses to the input pool's actual data through the
input_pool_data array directly.

threshold for /dev/random reads, presumably so that processes don't
hang. This value, random_write_wakeup_bits, is configurable anyway. So
all the no longer usefully named OUTPUT_POOL constants were doing was
setting a reasonable default for random_write_wakeup_bits. This commit

Originally, the RNG used several pools, so having things abstracted out
over a generic entropy_store object made sense. These days, there's only
one input pool, and then an uneven mix of usage via the abstraction and

used by WireGuard, uses HKDF quite strictly, which means we have to use
this. Because this really shouldn't be used by others, this commit moves
it into wireguard's noise.c locally, so that kernels that aren't using
WireGuard don't get this superfluous code baked in. On m68k systems,

"This introduces support for controlling the Cortex R7 co-processor in
Renesas Gen3, support for R5F clusters and C71x DSPs on TI J721S2 and
compute, audio and modem subsystems on Qualcomm SM6350.
It fixes a couple of sparse errors related to memcpy_to/fromio and
corrects the kerneldoc spelling of "Return:".

Pull more ACPI updates from Rafael Wysocki:
"The most significant item here is the Platform Firmware Runtime Update
and Telemetry (PFRUT) support designed to allow certain pieces of the
platform firmware to be updated on the fly, among other things.
Also important is the e820 handling change on x86 that should work
around PCI BAR allocation issues on some systems shipping since 2019.
The rest is just a handful of assorted fixes and cleanups on top of
the ACPI material merged previously.
Specifics:
- Add support for the the Platform Firmware Runtime Update and
Telemetry (PFRUT) interface based on ACPI to allow certain pieces
of the platform firmware to be updated without restarting the
system and to provide a mechanism for collecting platform firmware
telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
- Ignore E820 reservations covering PCI host bridge windows on
sufficiently recent x86 systems to avoid issues with allocating PCI
BARs on systems where the E820 reservations cover the entire PCI
host bridge memory window returned by the _CRS object in the
system's ACPI tables (Hans de Goede).
- Fix and clean up acpi_scan_init() (Rafael Wysocki).
- Add more sanity checking to ACPI SPCR tables parsing (Mark
Langsdorf).
- Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
- Drop unnecessary "static" from the ACPI PCC address space handling
driver added recently (kernel test robot)"
