commit acc657692aed438e9931438f8c923b2b107aebf9 upstream.
Fix the size check added to dns_resolver_preparse() for the V1 server-list
header so that it doesn't give EINVAL if the size supplied is the same as
the size of the header struct (which should be valid).
This can be tested with:
echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p
which will give "add_key: Invalid argument" without this fix.

The previous setting did not take into account the CSTN mode.
For the H_WAIT_2 bitfield (bits 0-7) of the LCDC Horizontal Configuration
Register (LCDCR), the IMX25RM manual states that:
In TFT mode, it specifies the number of SCLK periods between the end of
HSYNC and the beginning of OE signal, and the total delay time equals
(H_WAIT_2 + 3) of SCLK periods.
In CSTN mode, it specifies the number of SCLK periods between the end of
HSYNC and the first display data in each line, and the total delay time
equals (H_WAIT_2 + 2) of SCLK periods.
The patch handles both cases.

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

[ Upstream commit 2f1888281e67205bd80d3e8f54dbd519a9653f26 ]
The iser_reg_resources structure has two pointers to MR but only one
mr_valid field. The implementation assumes that we use only *sig_mr when
pi_enable is true. Otherwise, we use only *mr. However, it is only
sometimes correct. Read commands without protection information occur even
when pi_enble is true. For example, the following SCSI commands have a
Data-In buffer but never have protection information: READ CAPACITY (16),
INQUIRY, MODE SENSE(6), MAINTENANCE IN. So, we use
*sig_mr for some SCSI commands and *mr for the other SCSI commands.
In most cases, it works fine because the remote invalidation is applied.
However, there are two cases when the remote invalidation is not
applicable.
1. Small write commands when all data is sent as an immediate.
2. The target does not support the remote invalidation feature.
The lazy invalidation is used if the remote invalidation is impossible.
Since, at the lazy invalidation, we always invalidate the MR we want to
use, the wrong MR may be invalidated.
To fix the issue, we need a field per MR that indicates the MR needs
invalidation. Since the ib_mr structure already has such a field, let's
use ib_mr.need_inval instead of iser_reg_resources.mr_valid.

The mtk_dp driver registers a phy device which is handled by the

synchronously, proceeding to make use of functionality exposed by that

is built as a module, causing the mtk_dp driver to fail probe in this
case.
Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to
ensure the phy module has been loaded before the dp, so that the phy
probe happens synchrounously and the mtk_dp driver can probe
successfully even with the phy driver built as a module.

[ Upstream commit f33f5b1fd1be5f5106d16f831309648cb0f1c31d ]
Users report about the unexpected behavior for setting timeouts above
15 sec on Raspberry Pi. According to watchdog-api.rst the ioctl
WDIOC_SETTIMEOUT shouldn't fail because of hardware limitations.
But looking at the code shows that max_timeout based on the
register value PM_WDOG_TIME_SET, which is the maximum.
Since 664a39236e71 ("watchdog: Introduce hardware maximum heartbeat
in watchdog core") the watchdog core is able to handle this problem.
This fix has been tested with watchdog-test from selftests.

Avoid unnecessary crashes by claiming only NMIs that are due to
ERROR signalling or generated by the hpwdt hardware device.
The code does this, but only for iLO5.
The intent was to preserve legacy, Gen9 and earlier, semantics of
using hpwdt for error containtment as hardware/firmware would signal
fatal IO errors as an NMI with the expectation of hpwdt crashing
the system. Howerver, these IO errors should be received by hpwdt
as an NMI_IO_CHECK. So the test is overly permissive and should
not be limited to only ilo5.
We need to enable this protection for future iLOs not matching the
current PCI IDs.

[ Upstream commit 38d75297745f04206db9c29bdd75557f0344c7cc ]
When the new watchdog character device is registered, it becomes
available for opening. This creates a race where userspace may open the
device before the character device's owner is set. This results in an
imbalance in module_get calls as the cdev_get in cdev_open will not
increment the reference count on the watchdog driver module.
This causes problems when the watchdog character device is released as
the module loader's reference will also be released. This makes it
impossible to open the watchdog device later on as it now appears that
the module is being unloaded. The open will fail with -ENXIO from
chrdev_open.
The legacy watchdog device will fail with -EBUSY from the try_module_get
in watchdog_open because it's module owner is the watchdog core module
so it can still be opened but it will fail to get a refcount on the
underlying watchdog device driver.

Currently zynqmp divider round rate is considering single parent and
calculating rate and parent rate accordingly. But if divider clock flag
is set to SET_RATE_PARENT then its not trying to traverse through all
parent rate and not selecting best parent rate from that. So use common
divider_round_rate() which is traversing through all clock parents and
its rate and calculating proper parent rate.

Currently zynqmp clock driver is not calculating closest mux rate and
because of that Linux is not setting proper frequency for CPU and
not able to set given frequency for dynamic frequency scaling.
E.g., In current logic initial acpu clock parent and frequency as below
apll1 0 0 0 2199999978 0 0 50000 Y
acpu0_mux 0 0 0 2199999978 0 0 50000 Y
acpu0_idiv1 0 0 0 2199999978 0 0 50000 Y
acpu0 0 0 0 2199999978 0 0 50000 Y
After changing acpu frequency to 549999994 Hz using CPU freq scaling its
selecting incorrect parent which is not closest frequency.
rpll_to_xpd 0 0 0 1599999984 0 0 50000 Y
acpu0_mux 0 0 0 1599999984 0 0 50000 Y
acpu0_div1 0 0 0 533333328 0 0 50000 Y
acpu0 0 0 0 533333328 0 0 50000 Y
Parent should remain same since 549999994 = 2199999978 / 4.
So use __clk_mux_determine_rate_closest() generic function to calculate
closest rate for mux clock. After this change its selecting correct
parent and correct clock rate.
apll1 0 0 0 2199999978 0 0 50000 Y
acpu0_mux 0 0 0 2199999978 0 0 50000 Y

The hardware manual of both RZ/G2L and RZ/G3S specifies that the reset
monitor registers need to be interrogated when the reset signals are
toggled (chapters "Procedures for Supplying and Stopping Reset Signals"
and "Procedure for Activating Modules"). Without this, there is a
chance that different modules (e.g. Ethernet) are not ready after their
reset signal is toggled, leading to failures (on probe or resume from
deep sleep states).
The same indications are available for RZ/V2M for TYPE-B reset controls.
