The current CB_COMPOUND handling code tries to compare the principal
name of the request with the cl_hostname in the client. This is not
guaranteed to ever work, particularly if the client happened to mount
a CNAME of the server or a non-fqdn.
Fix this by instead comparing the cr_principal string with the acceptor
name that we get from gssd. In the event that gssd didn't send one
down (i.e. it was too old), then we fall back to trying to use the
cl_hostname as we do today.

This MIC virtual bus driver takes the responsibility of creating all
the virtual devices connected to the PCIe device on the host and the
platform device on the card. The MIC bus hardware operations provide
a way to abstract certain hardware details from the base physical devices.
Examples of devices added on the MIC virtual bus include host DMA and card DMA.
This abstraction enables using a common DMA driver on host and card.

This patch introduces a possibility for userspace to set various (so far
two) modes of generating addresses. This is useful for example for
NetworkManager because it can set the mode to NONE and take care of link
local addresses itself. That allow it to have the interface up,
monitoring carrier but still don't have any addresses on it.
One more use-case by Dan Williams:
<quote>
WWAN devices often have their LL address provided by the firmware of the
device, which sometimes refuses to respond to incorrect LL addresses
when doing DHCPv6 or IPv6 ND. The kernel cannot generate the correct LL
address for two reasons:
1) WWAN pseudo-ethernet interfaces often construct a fake MAC address,
or read a meaningless MAC address from the firmware. Thus the EUI64 and
the IPv6LL address the kernel assigns will be wrong. The real LL
address is often retrieved from the firmware with AT or proprietary
commands.
2) WWAN PPP interfaces receive their LL address from IPV6CP, not from
kernel assignments. Only after IPV6CP has completed do we know the LL
address of the PPP interface and its peer. But the kernel has already
assigned an incorrect LL address to the interface.
So being able to suppress the kernel LL address generation and assign
the one retrieved from the firmware is less complicated and more robust.

drm_rotation_simplify() can be used to eliminate unsupported rotation
flags. It will check if any unsupported flags are present, and if so
it will modify the rotation to an alternate form by adding 180 degrees
to rotation angle, and flipping the reflect x and y bits. The hope is
that this identity transform will eliminate the unsupported flags.
Of course that might not result in any more supported rotation, so
the caller is still responsible for checking the result afterwards.

The I2C devices that make up the STMicroelectronics MEMS sensors
may be sneakily enabled by cleverly giving the device node the same
name as a string match from the platform device ID table. However
the right method is to use the compatible string.
On detection, the ST sensors use the ID string to probe and
instatiate the right sensor driver, so pass the kernel-internal ID
string in the .data field of the OF match table, and set the I2C
client name to this name when a compatible match is used.
This avoids having misc Linux-specific strings floating around in
the device tree.

We can then scan the DRM device list for CRTCs to find their index,

What the patch does:
1. Call pinmux_disable_setting ahead of pinmux_enable_setting
each time pinctrl_select_state is called
2. Remove the HW disable operation in pinmux_disable_setting function.
3. Remove the disable ops in struct pinmux_ops
4. Remove all the disable ops users in current code base.
Notes:
1. Great thanks for the suggestion from Linus, Tony Lindgren and
Stephen Warren and Everyone that shared comments on this patch.
2. The patch also includes comment fixes from Stephen Warren.
The reason why we do this:
1. To avoid duplicated calling of the enable_setting operation
without disabling operation inbetween which will let the pin
descriptor desc->mux_usecount increase monotonously.
2. The HW pin disable operation is not useful for any of the
existing platforms.
And this can be used to avoid the HW glitch after using the
item #1 modification.
In the following case, the issue can be reproduced:
1. There is a driver that need to switch pin state dynamically,
e.g. between "sleep" and "default" state
2. The pin setting configuration in a DTS node may be like this:
component a {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&a_grp_setting &c_grp_setting>;
pinctrl-1 = <&b_grp_setting &c_grp_setting>;
}
The "c_grp_setting" config node is totally identical, maybe like
following one:
c_grp_setting: c_grp_setting {
pinctrl-single,pins = <GPIO48 AF6>;
}
3. When switching the pin state in the following official pinctrl
sequence:
pin = pinctrl_get();
state = pinctrl_lookup_state(wanted_state);
pinctrl_select_state(state);
pinctrl_put();
Test Result:
1. The switch is completed as expected, that is: the device's
pin configuration is changed according to the description in the
"wanted_state" group setting
2. The "desc->mux_usecount" of the corresponding pins in "c_group"
is increased without being decreased, because the "desc" is for
each physical pin while the setting is for each setting node
in the DTS.
Thus, if the "c_grp_setting" in pinctrl-0 is not disabled ahead
of enabling "c_grp_setting" in pinctrl-1, the desc->mux_usecount
will keep increasing without any chance to be decreased.
According to the comments in the original code, only the setting,
in old state but not in new state, will be "disabled" (calling
pinmux_disable_setting), which is correct logic but not intact. We
still need consider case that the setting is in both old state
and new state. We can do this in the following two ways:
1. Avoid to "enable"(calling pinmux_enable_setting) the "same pin
setting" repeatedly
2. "Disable"(calling pinmux_disable_setting) the "same pin setting",
actually two setting instances, ahead of enabling them.
Analysis:
1. The solution #2 is better because it can avoid too much
iteration.
2. If we disable all of the settings in the old state and one of
the setting(s) exist in the new state, the pins mux function
change may happen when some SoC vendors defined the
"pinctrl-single,function-off"
in their DTS file.
old_setting => disabled_setting => new_setting.
3. In the pinmux framework, when a pin state is switched, the
setting in the old state should be marked as "disabled".
Conclusion:
1. To Remove the HW disabling operation to above the glitch mentioned
above.
2. Handle the issue mentioned above by disabling all of the settings
in old state and then enable the all of the settings in new state.
