Add support to get and control a list of resets for the device
as optional and shared. These resets must be kept de-asserted until
the device is enabled.
This is specified as shared because some SoCs like UniPhier series
have common reset controls with all ahci controller instances.
However, according to Thierry's view,
https://www.spinics.net/lists/linux-ide/msg55357.html
some hardware-specific drivers already use their own resets,
and the common reset make a path to occur double controls of resets.
The ahci_platform_get_resources() can get and control the reset
only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

Add an extra argument to ahci_platform_get_resources(), that is
for the bitmap representing the resource to get in this function.
Currently there is no resources to be defined, so all the callers set
'0' to the argument.

There are two modes in which DEVSLP can be entered. The OS initiated or
hardware autonomous.
In hardware autonomous mode, BIOS configures the AHCI controller and the
device to enable DEVSLP. But they may not be ideal for all cases. So in
this case, OS should be able to reconfigure DEVSLP register.
Currently if the DEVSLP is already enabled, we can't set again as it will
simply return. There are some systems where the firmware is setting high
DITO by default, in this case we can't modify here to correct settings.
With the default in several seconds, we are not able to transition to
DEVSLP.
This change will allow reconfiguration of devslp register if DITO is
different.

We have seen that on some platforms, SATA device never show any DEVSLP
residency. This prevent power gating of SATA IP, which prevent system
to transition to low power mode in systems with SLP_S0 aka modern
standby systems. The PHY logic is off only in DEVSLP not in slumber.
Reference:
https://www.intel.com/content/dam/www/public/us/en/documents/datasheets
/332995-skylake-i-o-platform-datasheet-volume-1.pdf
Section 28.7.6.1
Here driver is trying to do read-modify-write the devslp register. But
not resetting the bits for which this driver will modify values (DITO,
MDAT and DETO). So simply reset those bits before updating to new values.

One of the requirement for modern x86 system to enter lowest power mode
(SLP_S0) is SATA IP block to be off. This is true even during when
platform is suspended to idle and not only in opportunistic (runtime)
suspend.
Several of these system don't have traditional ACPI S3, so it is
important that they enter SLP_S0 state, to avoid draining battery even
during suspend. So it is important that out of the box Linux installation
reach this state.
SATA IP block doesn't get turned off till SATA is in DEVSLP mode. Here
user has to either use scsi-host sysfs or tools like powertop to set
the sata-host link_power_management_policy to min_power.
This change sets by default link power management policy to min_power
with partial (preferred) or slumber support on idle for some platforms.
To avoid regressions, the following conditions are used:
- User didn't override the policy from module parameter
- The kernel config is already set to use med_power_with_dipm or deeper
- System is a SLP_S0 capable using ACPI low power idle flag
This combination will make sure that systems are fairly recent and
since getting shipped with SLP_S0 support, the DEVSLP function
is already validated.

Currently when min_power policy is selected, the partial low power state
is not entered and link will try aggressively enter to only slumber state.
Add a new policy which still enable DEVSLP but also try to enter partial
low power state. This policy is presented as "min_power_with_partial".
For information the difference between partial and slumber
Partial – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ns.
Slumber – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ms.
Devslp – PHY logic is powered down. The link PM exit latency from this
state to active state maximum is 20 ms, unless otherwise specified by
DETO.

Replace the explicit clock handling to enable/disable the SATA module by
calls to Runtime PM.
This makes the driver independent of actual SoC clock/power hierarchies,
and is needed to support virtualization, where the guest is not in full

ata_sff_data_xfer_noirq() is invoked via the ->sff_data_xfer hook. The
latter is invoked by ata_pio_sector(), atapi_send_cdb() and
__atapi_pio_bytes() which in turn is invoked by ata_sff_hsm_move().
The latter function requires that the "ap->lock" lock is held which
needs to be taken with disabled interrupts.
There is no need have to have ata_sff_data_xfer_noirq() which invokes
ata_sff_data_xfer32() with disabled interrupts because at this point the
interrupts are already disabled.
Remove the function and its references to it and replace all callers
with ata_sff_data_xfer32().

Switchdev notifications for addition of SWITCHDEV_OBJ_ID_PORT_VLAN are
distributed not only on clean addition, but also when flags on an
existing VLAN are changed. mlxsw_sp_bridge_port_vlan_add() calls
mlxsw_sp_port_vlan_get() to get at the port_vlan in question, which
implicitly references the object. This then leads to discrepancies in

determines it's a flag-only change.

Commit f34436a43092 ("net/ipv6: Simplify route replace and appending
into multipath route") changed the IPv6 route replace logic so that the
first matching route (i.e., same metric) is replaced.
Have mlxsw replace the first matching route as well.

Commit f34436a43092 ("net/ipv6: Simplify route replace and appending
into multipath route") changed the IPv6 route append logic so that
dev-only routes can be appended and not only gatewayed routes.
Align mlxsw with the new behaviour.

Johannes Berg says:
====================
A handful of fixes:
* missing RCU grace period enforcement led to drivers freeing
data structures before; fix from Dedy Lansky.
* hwsim module init error paths were messed up; fixed it myself
after a report from Colin King (who had sent a partial patch)
* kernel-doc tag errors; fix from Luca Coelho
* initialize the on-stack sinfo data structure when getting
station information; fix from Sven Eckelmann
* TXQ state dumping is now done from init, and when TXQs aren't
initialized yet at that point, bad things happen, move the
initialization; fix from Toke Høiland-Jørgensen.

stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before
calling napi_gro_receive().
The function assumes VLAN tagged frames are always tagged with
802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding
the parameter on call to __vlan_hwaccel_put_tag() .
This causes packets not to be passed to the VLAN slave if it was created
with 802.1AD protocol
(ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100).
This fix passes the protocol from the VLAN header into
__vlan_hwaccel_put_tag() instead of using the hard-coded value of
ETH_P_8021Q.
NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now
dependent on the correct combination of features and the detected vlan tag.
NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver
actual abilities.

We didn't free the workqueue on any errors, nor did we
correctly check for rhashtable allocation errors, nor
did we free the hashtable on error.

- make sure we only allow internally generates commands in any non-live
state
- only allow connect commands on non-live queues when actually in the
new or connecting states
- treat all other non-live, non-dead states the same as a default
cach-all
This fixes a regression where we could not shutdown a controller
orderly as we didn't allow the internal generated Property Set
command, and also ensures we don't accidentally let a Connect command
through in the wrong state.

Move the is_connected check to the fibre channel transport, as it has no
meaning for other transports. To facilitate this split out a new
nvmf_fail_nonready_command helper that is called by the transport when
it is asked to handle a command on a queue that is not ready.
Also avoid a function call for the queue live fast path by inlining
the check.
