Broadcom STB chips support a deep sleep mode where all register
contents are lost. Because we were stashing the MagicPacket password
into some of these registers a suspend into that deep sleep then a
resumption would not lead to being able to wake-up from MagicPacket with
password again.
Fix this by keeping a software copy of the password and program it
during suspend.

This reverts commit 6623c0fba10ef45b64ca213ad5dec926f37fa9a0.
The original diagnosis was incorrect: it appears that the NIC had
PHY polling mode enabled, which meant that it overwrote the PHYs
advertisement register during negotiation.

When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:
arch/arm64/mm/dump.c: 282
if (addr >= st->marker[1].start_address) {
called from:
arch/arm64/mm/dump.c: 331
note_page(st, addr, 2, pud_val(pud));
because st->marker++ is is called after "UEFI runtime end" which is the
last element in addr_marker[]. Therefore, add a terminator like the one
for kernel_page_tables, so it can be skipped to print out non-existent
markers.
Here's the KASAN bug report:

atchan->status variable is used to store two different information:
- pass channel interrupts status from interrupt handler to tasklet;
- channel information like whether it is cyclic or paused;
This causes a bug when device_terminate_all() is called,
(AT_XDMAC_CHAN_IS_CYCLIC cleared on atchan->status) and then a late End
of Block interrupt arrives (AT_XDMAC_CIS_BIS), which sets bit 0 of
atchan->status. Bit 0 is also used for AT_XDMAC_CHAN_IS_CYCLIC, so when
a new descriptor for a cyclic transfer is created, the driver reports
the channel as in use:
if (test_and_set_bit(AT_XDMAC_CHAN_IS_CYCLIC, &atchan->status)) {
dev_err(chan2dev(chan), "channel currently used\n");
return NULL;
}
This patch fixes the bug by adding a different struct member to keep
the interrupts status separated from the channel status bits.

The aic94xx driver is currently failing to load with errors like
sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:03.0/0000:02:00.3/0000:07:02.0/revision'
Because the PCI code had recently added a file named 'revision' to every
PCI device. Fix this by renaming the aic94xx revision file to
aic_revision. This is safe to do for us because as far as I can tell,
there's nothing in userspace relying on the current aic94xx revision file
so it can be renamed without breaking anything.

The remove path contains a hack which depends on internal structures in
other source files, similar to the one which was recently removed from
the registration path. Since commit 1ce9e6055fa0 ("virtio_ring:
introduce packed ring support"), this leads to a crash when vop devices
are removed.
The structure in question is only examined to get the virtual address of
the allocated used page. Store that pointer locally instead to fix the
crash.

KASAN detects a use-after-free when vop devices are removed.
This problem was introduced by commit 0063e8bbd2b62d136 ("virtio_vop:
don't kfree device on register failure"). That patch moved the freeing
of the struct _vop_vdev to the release function, but failed to ensure
that vop holds a reference to the device when it doesn't want it to go
away. A kfree() was replaced with a put_device() in the unregistration
path, but the last reference to the device is already dropped in
unregister_virtio_device() so the struct is freed before vop is done
with it.
Fix it by holding a reference until cleanup is done. This is similar to
the fix in virtio_pci in commit 2989be09a8a9d6 ("virtio_pci: fix use
after free on release").

binderfs should not have a separate device_initcall(). When a kernel is
compiled with CONFIG_ANDROID_BINDERFS register the filesystem alongside
CONFIG_ANDROID_IPC. This use-case is especially sensible when users specify
CONFIG_ANDROID_IPC=y, CONFIG_ANDROID_BINDERFS=y and
ANDROID_BINDER_DEVICES="".
When CONFIG_ANDROID_BINDERFS=n then this always succeeds so there's no
regression potential for legacy workloads.

When initializing clocks, a reference to the TCON channel 0 clock is
obtained. However, the clock is never prepared and enabled later.
Switching from simplefb to DRM actually disables the clock (that was
usually configured by U-Boot) because of that.
On the V3s, this results in a hang when writing to some mixer registers
when switching over to DRM from simplefb.
Fix this by preparing and enabling the clock when initializing other
clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is
apparently too late and results in the same mixer register access hang.

This patch fixes the incorrect external id that kernel reports to user mode
driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should
start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while
rev_id == 1.

Revert commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal").
That commit breaks boot on Macchiatobin board when a Mellanox NIC is
present in the PCIe slot.
It turns out that full reset cycle requires first comphy serdes
initialization. Reset signal toggle without comphy initialization makes
access to PCI configuration registers stall indefinitely. U-Boot toggles
the Macchiatobin PCIe reset line already at boot, after initializing the
comphy serdes.
So while commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal") enables PCIe on platforms that U-Boot does not touch the
reset line (like Clearfog GT-8K), it breaks PCIe (and boot) on the
Macchiatobin board.
Revert commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal") entirely to fix the Macchiatobin regression.

When calling firmware to allocate a CP ring or NQ, an interrupt associated
with that ring may be generated immediately before the doorbell is even
setup after the firmware call returns. When servicing the interrupt, the

There still is a race window after the commit b027e2298bd588
("tty: fix data race between tty_init_dev and flush of buf"),
and we encountered this crash issue if receive_buf call comes
before tty initialization completes in tty_open and
tty->driver_data may be NULL.
CPU0 CPU1
---- ----
tty_open
tty_init_dev
tty_ldisc_unlock

n_tty_receive_buf_common
__receive_buf
uart_flush_chars
uart_start
/*tty->driver_data is NULL*/
tty->ops->open
/*init tty->driver_data*/
it can be fixed by extending ldisc semaphore lock in tty_init_dev
to driver_data initialized completely after tty->ops->open(), but
this will lead to get lock on one function and unlock in some other
function, and hard to maintain, so fix this race only by checking
tty->driver_data when receiving, and return if tty->driver_data
is NULL, and n_tty_receive_buf_common maybe calls uart_unthrottle,
so add the same check.
Because the tty layer knows nothing about the driver associated with the
device, the tty layer can not do anything here, it is up to the tty
driver itself to check for this type of race. Fix up the serial driver
to correctly check to see if it is finished binding with the device when
being called, and if not, abort the tty calls.

There's an issue with how sense requests are handled in IDE. If ide-cd
encounters an error, it queues a sense request. With how IDE request
handling is done, this is the next request we need to handle. But it's
impossible to guarantee this, as another request could come in between
the sense being queued, and ->queue_rq() being run and handling it. If
that request ALSO fails, then we attempt to doubly queue the single
sense request we have.
Since we only support one active request at the time, defer request
processing when a sense request is queued.

When Sink negotiates PPS, the voltage range of selected PPS APDO might
not cover the previous voltage (out_volt). If the previous out_volt is
lower than the new min_volt, the output voltage in RDO might be set to
an invalid value. For instance, supposed that the previous voltage is
5V, and the new voltage range in the APDO is 7V-12V. Then the output
voltage in the RDO should not be set to 5V which is lower than the
possible min_volt 7V.
Fix this by choosing the maximal value between the previous voltage and
the new min_volt first. And ensure that this value will not exceed the
new max_volt. The new out_volt will fall within the new voltage range
while being the closest value compared to the previous out_volt.

usb: fixes for v5.0-rc4
Dwc3 got a fix for cases when gadget driver queue an OUT request of
length 0; this is a case that has been overlooked for quite some time
now.
Exynos' dwc3 glue layer got a fix on the error path for those cases
where clk_prepare_enable() fails.
TI's AM335x PHY driver got a fix for a race condition during
probe. This race happened because driver was powering off the PHY only
after adding the PHY handle to the framework. The result is that we
could fall into a situation where user of the PHY (MUSB) could call
phy_init() before phy driver's probe() called phy_poweroff() which
would result in a powered off PHY after phy_init() was called.
The old net2272 driver got a fix for an erroneous use of bitwise
negation.

The number of TSO enabled channels in HW can be different than the
number of total channels. There is no way to determined, at runtime, the
number of TSO capable channels and its safe to assume that if TSO is
enabled then at least channel 0 will be TSO capable.
Lets always send TSO packets from Queue 0.
