I have a system which has an EVGA X99 Classified motherboard. The pin
assignments for the HD Audio controller are not correct under Linux.
Windows 10 works fine and informs me that it's using the Recon3Di

We know the version is 3 if on a v5 file system. For earlier file
systems formats we always upgrade the remaining v1 inodes to v2 and
thus only use v2 inodes. Use the xfs_sb_version_has_large_dinode
helper to check if we deal with small or large dinodes, and thus
remove the need for the di_version field in struct icdinode.

di_flags2 is initialized to zero for v4 and earlier file systems. This
means di_flags2 can only be non-zero for a v5 file systems, in which
case both the parent and child inodes can store the field. Remove the
extra di_version check, and also remove the rather pointless local
di_flags2 variable while at it.

The size of the dinode structure is only dependent on the file system

Add a new wrapper to check if a file system supports the v3 inode format
with a larger dinode core. Previously we used xfs_sb_version_hascrc for
that, which is technically correct but a little confusing to read.
Also move xfs_dinode_good_version next to xfs_sb_version_has_v3inode
so that we have one place that documents the superblock version to
inode version relationship.

There is the code in the read_symbol function in 'scripts/kallsyms.c':
if (is_ignored_symbol(name, type))
return NULL;
/* Ignore most absolute/undefined (?) symbols. */
if (strcmp(name, "_text") == 0)
_text = addr;
But the is_ignored_symbol function returns true for name="_text" and
type='A'. So the next condition is not executed and the _text variable
is always zero.
It makes the wrong kallsyms_relative_base symbol as a result of the code
(CONFIG_KALLSYMS_BASE_RELATIVE is defined):
if (base_relative) {
output_label("kallsyms_relative_base");
output_address(relative_base);
printf("\n");
}
Because the output_address function uses the _text variable.
So the kallsyms_lookup function and all related functions in the kernel
do not work properly. For example, the stack trace in oops:
Call Trace:
[aa095e58] [809feab8] kobj_ns_ops_tbl+0x7ff09ac8/0x7ff1c1c4 (unreliable)

The device-managed allocation API doesn't work well with the life-cycle
of device objects. Since ports have device objects allocated within, it
can lead to situations where these devices need to stay around until
after their parent pad controller has been unbound from its driver. The
device-managed memory allocated for the port objects will, however, get
freed when the pad controller unbinds from the driver. This can cause
use-after-free errors down the road.
Note that the device is deleted as part of the driver unbind operation,
so there isn't much that can be done with it after that point, but the
memory still needs to stay around to ensure none of the references are
invalidated.
One situation where this arises is when a VBUS supply is associated with
a USB 2 or 3 port. When that supply is released using regulator_put() an
SRCU call will queue the release of the device link connecting the port
and the regulator after a grace period. This means that the regulator is
going to keep on to the last reference of the port device even after the
pad controller driver was unbound (which is when the memory backing the
port device is freed).
Fix this by allocating port objects using non-device-managed memory. Add
release callbacks for these objects so that their memory gets freed when
the last reference goes away. This decouples the port devices' lifetime
from the "active" lifetime of the pad controller (i.e. the time during
which the pad controller driver owns the device).

Devices are created for each port of the XUSB pad controller. Each USB 2
and USB 3 port can potentially have an associated VBUS power supply that
needs to be removed when the device is removed.
Since port devices never bind to a driver, the driver core will not get
to perform the cleanup of device-managed resources that usually happens
on driver unbind.
Now, the driver core will also perform device-managed resource cleanup
for driver-less devices when they are released. However, when a device
link is created between the regulator and the port device, as part of
regulator_get(), the regulator takes a reference to the port device and
prevents it from being released unless regulator_put() is called, which
will never happen.
Avoid this by using the non-device-managed API and manually releasing
the regulator reference when the port is unregistered.

Probe deferral is an expected error condition that will usually be
recovered from. Print such error messages at debug level to make them
available for diagnostic purposes when building with debugging enabled
and hide them otherwise to not spam the kernel log with them.

Deferred probe is an expected return value for tegra_fuse_readl().
Given that the driver deals with it properly, there's no need to
output a warning that may potentially confuse users.

Add support for the XUSB pad controller found on Tegra194 SoCs. It is
mostly similar to the same IP found on Tegra186, but the number of
pads exposed differs, as do the programming sequences. Because most of
the Tegra194 XUSB PADCTL registers definition and programming sequence
are the same as Tegra186, Tegra194 XUSB PADCTL can share the same
driver, xusb-tegra186.c, with Tegra186 XUSB PADCTL.
Tegra194 XUSB PADCTL supports up to USB 3.1 Gen 2 speed, however, it
is possible for some platforms have long signal trace that could not
provide sufficient electrical environment for Gen 2 speed. This patch
adds a "maximum-speed" property to usb3 ports which can be used to
specify the maximum supported speed for any particular USB 3.1 port.
For a port that is not capable of SuperSpeedPlus, "maximum-speed"
property should carry "super-speed".

As xusb-tegra186.c will be reused for Tegra194, it would be good to
protect Tegra186 soc data with CONFIG_ARCH_TEGRA_186_SOC. This commit
also reshuffles Tegra186 soc data single CONFIG_ARCH_TEGRA_186_SOC
will be sufficient.
