In the UFS error handling flow, the host will send a device management cmd
(NOP OUT) to the device for link recovery. If this cmd times out and
clearing the doorbell fails, ufshcd_wait_for_dev_cmd() will do nothing and
return. hba->dev_cmd.complete struct is not set to NULL.
When this happens, if cmd has been completed by device, then we will call
complete() in __ufshcd_transfer_req_compl(). Because the complete struct is

The three DMA memory regions allocated for the host memory space are
documented to require alignment of 128, 1024, and 1024 respectively, but
the returned address is checked for PAGE_SIZE alignment.
In the case where these allocations are serviced by e.g. the Arm SMMU, the
size and alignment will be determined by its supported page sizes. In most
cases SZ_4K and a few larger sizes are available.
In the typical configuration this does not cause problems, but in the event
that the system PAGE_SIZE is increased beyond 4k, it's no longer reasonable
to expect that the allocation will be PAGE_SIZE aligned.
Limit the DMA alignment check to the actual alignment requirements written
in the comments in the code, to avoid the UFS core refusing to initialize
with such configuration.

Above that, the symbol that guards the other call was recently removed, so
that is all dead code at the moment.
Remove the incorrect #ifdef and instead of a Kconfig dependency to only
allow building the driver when CONFIG_GENERIC_MSI_IRQ is enabled. This
symbol is always present when PCI_MSI or ARM_GIC_V3_ITS are enabled, both
of which should be present on kernels that can run on Qualcomm SoCs.
The 'select RESET_CONTROLLER' in combination with this dependency
unfortunately causes a dependency loop and this is a user-visible symbol,
so it's better to change both to 'depends on'.

All UFS host controllers support DMA clustering. Hence enable DMA
clustering.
Notes:
- The max_segment_size parameter implements the 256 KiB limit for the
PRDT. The dma_boundary parameter represents a boundary that must not be
crossed by DMA scatter/gather lists. I'm not aware of any restrictions
on DMA scatter/gather lists in the UFSHCI specification other than the
256 KiB limit for the PRDT and the 32-bit address restriction for
controllers that only support 32-bits DMA. The latter restriction is
already handled by ufshcd_set_dma_mask().
- Without patch "scsi: ufs: exynos: Fix the maximum segment size", this
patch breaks support for the Exynos controller.
The history of the dma_boundary parameter in the UFS driver is as
follows:
* The initial UFS driver did not set the dma_boundary parameter.
* Commit 4dd4130a72 ("scsi: make sure all drivers set the use_clustering
flag") set the .use_clustering flag.
* Commit 4af14d113b ("scsi: remove the use_clustering flag") removed the
use_clustering flag and set the dma_boundary parameter instead.

The use of kmap() is deprecated in favor of kmap_local_page().
There are two main problems with kmap(): (1) It comes with an overhead as
the mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation when the
kmap’s pool wraps and it might block when the mapping space is fully
utilized until a slot becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts). It
is faster than kmap() in kernels with HIGHMEM enabled. Furthermore, the
tasks can be preempted and, when they are scheduled to run again, the
kernel virtual addresses are restored and still valid.
Therefore, replace kmap() with kmap_local_page() in ipr_copy_ucode_buffer()
and, instead of open-coding local mappings + memcpy() + local un-mappings,
use the better suited memcpy_to_page() helper.

kmap_atomic() is deprecated in favor of kmap_local_page(). Therefore,
replace kmap_atomic() with kmap_local_page() in ips_is_passthru(). In the
meantime remove an unnecessary comment, align code, and remove spaces.
kmap_atomic() is implemented like a kmap_local_page() which also disables
page-faults and preemption (the latter only for !PREEMPT_RT kernels). The
code within the mapping/unmapping in ips_is_passthru() is already in atomic
context because of a call to local_irq_save() and kmap_local_page() can be
called in atomic context too (including interrupts).
Therefore, a mere replacement of the old API with the new one is all it is
required (i.e., there is no need to explicitly add any calls to
pagefault_disable() and/or preempt_disable()).
