This event is raised when link is lost as specified in UFSHCI spec and that
means communication is not possible. Thus initializing UFS interface needs
to be done.
Make UFS driver considers Link Lost as fatal in the INT_FATAL_ERRORS
mask. This will trigger a host reset whenever a link lost interrupt occurs.

The return value of ufshcd_set_dev_pwr_mode() is passed to device PM
core. However, the function currently returns a SCSI result which the PM
core doesn't understand. This might lead to unexpected behaviors in
userland; a platform reset was observed in Android.
Use a generic error code for SSU failures.

According to the comment in check_fw_ready() we should not check the
IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.
However we check this very field in process_oq() for processing the highest
index interrupt vector. The highest interrupt vector is checked as the FW
is programmed to signal fatal errors through this irq.
Change that function to not check IOP1_READY for those mentioned
controllers, but do check ILA_READY in both cases.
The reason I assume that this was not hit earlier was because we always
allocated 64 MSI(X), and just did not pass the vector index check in
process_oq(), i.e. the handler never ran for vector index 63.

If FCoE is not configured, libfc/libfcoe keeps on retrying FLOGI and after
3 retries driver does a context reset and tries fipvlan again. This leads
to context reset message flooding the logs. Hence ratelimit the message to
prevent flooding the logs.

kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to
know what sysctl knobs you wish to add for your own piece of code, we
just care about the core logic.
So move the sg-big-buff sysctl from kernel/sysctl.c to drivers/scsi/sg.c
and use register_sysctl() to register the sysctl interface.

Since it is possible for ioremap() to fail, 'data->MmioAddress' could be

The Tactive time determines the waiting time before burst at hibern8 exit
and is determined by hardware at linkup time. However, in the case of
Samsung devices, increase host's Tactive time +100us for stability. If the
HCI's Tactive time is equal or greater than the device, +100us should be
set.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also
fail for the same reason.
Simplify code and remove some dead code accordingly.
While at it, return the error code returned by dma_set_mask_and_coherent()
instead of -1.

In commit 29e2bac874 ("scsi: hisi_sas: Fix some issues related to
asd_sas_port->phy_list"), we use asd_sas_port->phy_mask instead of
accessing asd_sas_port->phy_list, and it is enough to use
asd_sas_port->phy_mask to check the state of phy, so remove the unused
check and variable.

Error handling steps were not in sequence as per the programmers
manual. Expected sequence:
- PHY_DOWN (PORT_IN_RESET)
- PORT_RESET_TIMER_TMO
- Host aborts pending I/Os
- Host deregister the device
- Host sends HW_EVENT_PHY_DOWN ACK
Previously we were sending HW_EVENT_PHY_DOWN ACK first and then deregister
the device. Fix this to use the expected sequence.

Add support for the io_uring interface in I/O-polled mode.
This feature is disabled in the driver by default. To enable the feature, a
module parameter "poll_queues" has to be set with the desired number of
polling queues.
When the feature is enabled, the driver reserves a certain number of
operational queue pairs for the poll_queues either from the available queue
pairs or creates additional queue pairs based on the operational queue
availability.
The Polling queues will have corresponding IRQ and ISR functions as similar
to default queues. However, the IRQ line is disabled by the driver for
poll_queues.
