Pull SCSI updates from James Bottomley:
"This series has a huge amount of churn because it pulls in Mauro's doc
update changing all our txt files to rst ones.
Excluding that, we have the usual driver updates (qla2xxx, ufs, lpfc,
zfcp, ibmvfc, pm80xx, aacraid), a treewide update for scnprintf and
some other minor updates.
The major core change is Hannes moving functions out of the aacraid
driver and into the core"

Pull EFI updates from Ingo Molnar:
"The EFI changes in this cycle are much larger than usual, for two
(positive) reasons:
- The GRUB project is showing signs of life again, resulting in the
introduction of the generic Linux/UEFI boot protocol, instead of
x86 specific hacks which are increasingly difficult to maintain.
There's hope that all future extensions will now go through that
boot protocol.
- Preparatory work for RISC-V EFI support.
The main changes are:
- Boot time GDT handling changes
- Simplify handling of EFI properties table on arm64
- Generic EFI stub cleanups, to improve command line handling, file
I/O, memory allocation, etc.
- Introduce a generic initrd loading method based on calling back
into the firmware, instead of relying on the x86 EFI handover
protocol or device tree.
- Introduce a mixed mode boot method that does not rely on the x86
EFI handover protocol either, and could potentially be adopted by
other architectures (if another one ever surfaces where one
execution mode is a superset of another)
- Clean up the contents of 'struct efi', and move out everything that
doesn't need to be stored there.
- Incorporate support for UEFI spec v2.8A changes that permit
firmware implementations to return EFI_UNSUPPORTED from UEFI
runtime services at OS runtime, and expose a mask of which ones are
supported or unsupported via a configuration table.
- Partial fix for the lack of by-VA cache maintenance in the
decompressor on 32-bit ARM.
- Changes to load device firmware from EFI boot service memory
regions
- Various documentation updates and minor code cleanups and fixes"

We were setting bActiveICCLevel attribute for UFS device only once but the
type of this attribute has changed from persistent to volatile since UFS
device specification v2.1. This attribute is set to the default value after
power cycle or hardware reset event. It isn't safe to rely on prefetched
data (only used for bActiveICCLevel attribute now). Hence this change
removes the code related to data prefetching and set this parameter on
every attempt to probe the UFS device.

Correct race condition where ioaccel is re-enabled before the raid_map is
updated. For RAID_1, RAID_1ADM, and RAID 5/6 there is a BUG_ON called which
is bad.
- Change event thread to disable ioaccel only. Send all requests down the
RAID path instead.
- Have rescan thread handle offload_enable.
- Since there is only one rescan allowed at a time, turning
offload_enabled on/off should not be racy. Each handler queues up a
rescan if one is already in progress.
- For timing diagram, offload_enabled is initially off due to a change

Block layer RPM is enabled for the genernal UFS SCSI devices when they are
probed by their driver. However block layer RPM is not enabled for UFS
well-known SCSI devices.
As UFS SCSI devices have their corresponding BSG char devices, accessing a
BSG char device via IOCTL may send requests to its corresponding SCSI
device through its request queue. If BSG IOCTL sends a request to a
well-known SCSI device when HBA is not runtime active, due to block layer
RPM not being enabled for the well-known SCSI devices, the HBA, which is at
the top of a SCSI device's parent chain, will not be resumed.
This change enables block layer RPM for the well-known SCSI devices so that
block layer can handle RPM for the well-known SCSI devices just like for
the general SCSI devices.

If an iSCSI connection happens to fail while the daemon isn't running (due
to a crash or for another reason), the kernel failure report is not
received. When the daemon restarts, there is insufficient kernel state in
sysfs for it to know that this happened. open-iscsi tries to reopen every
connection, but on different initiators, we'd like to know which
connections have failed.
There is session->state, but that has a different lifetime than an iSCSI
connection, so it doesn't directly reflect the connection state.

There is no reason to expose SATA_PMP config option when no SATA
host drivers are enabled. To fix it add SATA_HOST config option,
make all SATA host drivers select it and finally make SATA_PMP
config options depend on it.
This also serves as preparation for the future changes which
optimize libata core code size on PATA only setups.

Some USB bridge devices will return a default set of characteristics during
initialization. And then, once an attached drive has spun up, substitute
the actual parameters reported by the drive. According to the SCSI spec,
the device should return a UNIT ATTENTION in case any reported parameters
change. But in this case the change is made silently after a small window
where default values are reported.
Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of
physical block size") validated the reported optimal I/O size against the
physical block size to overcome problems with devices reporting nonsensical
transfer sizes. However, this validation did not account for the fact that
aforementioned devices will return default values during a brief window
during spin-up. The subsequent change in reported characteristics would
invalidate the checking that had previously been performed.
Unset a previously configured optimal I/O size should the sanity checking
fail on subsequent revalidate attempts.

struct partition is the on-disk format of a MSDOS partition table entry.
Move it out of genhd.h into a new msdos_partition.h header and give it
a msdos_ prefix to avoid confusion.
Also move the magic number from block/partitions/msdos.h to the new
header so that it can be used by the SCSI drivers looking at the DOS
partition tables.

Added the sysfs attribute for non fatal log so that management utility can
get the non fatal dump from driver. The non-fatal error is an error
condition or abnormal behavior detected by the host, or detected and
reported by the controller to the host.The non-fatal error does not stop
the controller firmware and enables it to still respond to host requests.
A typical example of a non-fatal error is an I/O timeout or an unusual
error notification from the controller. Since the firmware is operational,
the error dump information is pushed to host memory (by firmware) upon
request from the host.

2) There are goto targets for trying to cleanup if the hw fails to
initialize, but there's some overlap depending on who thinks they own
the sub-structures.

In pm80xx driver, the command mpi_set_phy_profile_req is sent by host
during boot to configure the phy profile such as analog setting page, rate
control page. However, the tag is not freed when its response is
received. As a result, 16 tags are missing for each HBA after boot. When
NCQ is enabled with queue depth 16, it needs at least, 15 * 16 = 240 tags
for each HBA to achieve the best performance. In current pm80xx driver with
setting CCB_MAX = 256, the total number of tags in each HBA is 255 for data
IO. Hence, without returning those tags to the pool after boot, some device
will finally be forced to non-ncq mode by ATA layer due to excessive errors
(i.e. LLDD cannot allocate tag for queued task).

A kexec reboot causes the controller fw to assert. This assertion shows up
in two ways, the controller doesn't show up as ready and an interrupt is
waiting as soon as the handler is registered. To resolve this added below
fix:
- Split the interrupt handling setup into two parts, setup and request.
- If the controller ready register indicates not-ready, but that the not
readiness is only on the IOC units we can still try a reset to bring the
system back to the pre-reboot state.

Increasing the per-request size maximum (max_sectors_kb) runs into the
per-device DMA scatter gather list limit (max_segments) for users of the io
vector system calls (eg, readv and writev). This is because the kernel
combines io vectors into DMA segments when possible, but it doesn't work
for our user because the vectors in the buffer cache get scrambled. This
change bumps the advertised max scatter gather length to 528 to cover 2M w/
x86's 4k pages and some extra for the user checksum. It trims the size of
some of the tables we don't care about and exposes all of the command slots
upstream to the SCSI layer. Also reduced the PM8001_MAX_CCB to 256 as
pm8001 driver has memory limit depend on machine capability. If we increase
the sg length, we need to trade-off it by decreasing PM8001_MAX_CCB.
PM8001_MAX_CCB = 256 does not have any influence on normal use
