Pull more SCSI updates from James Bottomley:
"This is a batch of changes that didn't make it in the initial pull
request because the lpfc series had to be rebased to redo an incorrect
split.
It's basically driver updates to lpfc, target, bnx2fc and ufs with the
rest being minor updates except the sr_block_release one which fixes a
use after free introduced by the removal of the global mutex in the
first patch set"

The original patch was to resolve the lldd being able to be unloaded
while being used to talk to the boot device of the system. However, the
end result of the original patch is that any driver unload while a nvme
controller is live via the lldd is now being prohibited. Given the module
reference, the module teardown routine can't be called, thus there's no
way, other than manual actions to terminate the controllers.

Generic protection fault type kernel panic is observed when user performs
soft (ordered) HBA unplug operation while IOs are running on drives
connected to HBA.
When user performs ordered HBA removal operation, the kernel calls PCI
device's .remove() call back function where driver is flushing out all the
outstanding SCSI IO commands with DID_NO_CONNECT host byte and also unmaps
sg buffers allocated for these IO commands.
However, in the ordered HBA removal case (unlike of real HBA hot removal),
HBA device is still alive and hence HBA hardware is performing the DMA
operations to those buffers on the system memory which are already unmapped
while flushing out the outstanding SCSI IO commands and this leads to
kernel panic.
Don't flush out the outstanding IOs from .remove() path in case of ordered
removal since HBA will be still alive in this case and it can complete the
outstanding IOs. Flush out the outstanding IOs only in case of 'physical
HBA hot unplug' where there won't be any communication with the HBA.
During shutdown also it is possible that HBA hardware can perform DMA
operations on those outstanding IO buffers which are completed with
DID_NO_CONNECT by the driver from .shutdown(). So same above fix is applied
in shutdown path as well.
It is safe to drop the outstanding commands when HBA is inaccessible such
as when permanent PCI failure happens, when HBA is in non-operational
state, or when someone does a real HBA hot unplug operation. Since driver
knows that HBA is inaccessible during these cases, it is safe to drop the
outstanding commands instead of waiting for SCSI error recovery to kick in
and clear these outstanding commands.

Currently ufshcd driver assumes that bInitPowerMode parameter is not
changed by any vendors thus device power mode can be set as "Active" during
initialization.
According to UFS JEDEC specification, device power mode shall be "Active"
after HW Reset is triggered if the bInitPowerMode parameter in Device
Descriptor is default value.
By above description, we can set device power mode as "Active" after device
reset is triggered by vendor's callback. With this change, the link startup
performance can be improved in some cases by not setting link_startup_again
as true in ufshcd_link_startup().

If the daemon is restarted or crashes while logging out of a session, the
unbind session event sent by the kernel is not processed and is lost. When
the daemon starts again, the session can't be unbound because the daemon is
waiting for the event message. However, the kernel has already logged out
and the event will not be resent.
When iscsid restart is complete, logout session reports error:
Logging out of session [sid: 6, target: iqn.xxxxx, portal: xx.xx.xx.xx,3260]
iscsiadm: Could not logout of [sid: 6, target: iscsiadm -m node iqn.xxxxx, portal: xx.xx.xx.xx,3260].
iscsiadm: initiator reported error (9 - internal error)
iscsiadm: Could not logout of all requested sessions
Make sure the unbind event is emitted.

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"

The default lun queue depth by the driver has been 30 for many years.
However, this value, when used with more recent hardware, has actually
throttled some tests that concentrate io on a lun.
Increase the default lun queue depth to 64.
Queue full handling, reported by the target, remains in effect and
unchanged.

Driver received a SCSI completion after it posted the cleanup request. This
leads to a problem that one ref count wasn't released leading to
flush_active_ios to get struck. The callback from libfc never returned and
other ports were not processed leading to APD.
Decrease the refcnt as well as try to complete if something is waiting for
completion.

Filesystem goes to read-only after continuous error injection because RQE
was handled in deferred context, leading to mismatch between CQE and RQE.
Specifically, this patch makes the following changes:
- Process the RQE with CQE in interrupt context, before putting it into
the work queue.
- Producer and consumer indices are also updated in the interrupt context
to guarantee the the order of processing.

Once fail happens during suspend and resume flow if the desired low power
link state is H8, link recovery is required for MediaTek UFS controller.
For resume flow, since power and clocks are already enabled before invoking
vendor's resume callback, simply using ufshcd_link_recovery() inside
callback is fine.
For suspend flow, the device power enters low power mode or is disabled
before suspend callback, thus ufshcd_link_recovery() can not be directly
used in vendor callback. One solution is to set the link to off state and
then ufshcd_host_reset_and_restore() will be executed by ufshcd_suspend().

The cpu io statistics were capped by a hard define limit of 128. This
effectively was a max number of CPUs, not an actual CPU count, nor actual
CPU numbers which can be even larger than both of those values. This made
stats off/misleading and on large CPU count systems, wrong.
Fix the stats so that all CPUs can have a stats struct. Fix the looping
such that it loops by hdwq, finds CPUs that used the hdwq, and sum the
stats, then display.

The AER interfaces to clear error status registers were a confusing mess:
- pci_cleanup_aer_uncorrect_error_status() cleared non-fatal errors
from the Uncorrectable Error Status register.
- pci_aer_clear_fatal_status() cleared fatal errors from the
Uncorrectable Error Status register.
- pci_cleanup_aer_error_status_regs() cleared the Root Error Status
register (for Root Ports), the Uncorrectable Error Status register,
and the Correctable Error Status register.
Rename them to make them consistent:
From To
---------------------------------------- -------------------------------
pci_cleanup_aer_uncorrect_error_status() pci_aer_clear_nonfatal_status()
pci_aer_clear_fatal_status() pci_aer_clear_fatal_status()
pci_cleanup_aer_error_status_regs() pci_aer_clear_status()
Since pci_cleanup_aer_error_status_regs() (renamed to
pci_aer_clear_status()) is only used within drivers/pci/, move the
declaration from <linux/aer.h> to drivers/pci/pci.h.

The lpfc_sli4_wq_release() routine iterates for each interim value when

Injecting EEH on a 32GB card is causing kernel oops
The pci error handler is doing an IO flush and the offline code is also
doing an IO flush. When the 1st flush is complete the hdwq is destroyed
(freed), yet the second flush accesses the hdwq and crashes.
Added a check in lpfc_sli4_fush_io_rings to check both the HBA_IOQ_FLUSH
flag and the hdwq pointer to see if it is already set and not already
freed.

SCSI layer sends driver IOs with more s/g segments than driver can handle.
This results in "Too many sg segments from dma_map_sg. Config 64, seg_cnt
219" error messages from the lpfc_scsi_prep_dma_buf_s3() routine.
The was due to use the driver using individual templates for pport and
vport, host reset enabled or not, nvme vs scsi, etc. In the end, there was
a combination for a vport that didn't match the pport.
Rather than enumerating more templates and more discretionary assignments,
revert to a base template that is copied to a template specific to the
pport/vport. Then, based on role, attributes and sli type, modify the
fields that are different for that port. Added a log message to
lpfc_create_port to validate values.

In lpfc_nvmet_prep_fcp_wqe() the line "rsp->sg_cnt = 0" is modifying the
transport's data structure. This may result in the transport believing the
s/g list was already freed, thus may not unmap/free it properly. Lpfc
driver should not modify the transport data structure.
The zeroing of the sg_cnt is to avoid use of the transport's sgl in a
subsequent loop where the driver builds the necessary requests for the
adapter firmware to complete the IO.
Change LLDD to use a local copy of the transport sg_cnt when building
requests to be passed to the adapter fw.

When processing the completion of a "Reg Rpi" login mailbox command in
lpfc_sli_def_mbox_cmpl, a call may be made to lpfc_unreg_login. The vpi is
extracted from the completing mailbox context and passed as an input for
the next. However, the vpi stored in the mailbox command context is an
absolute vpi, which for SLI4 represents both base + offset. When used with
a non-zero base component, (function id > 0) this results in an
out-of-range access beyond the allocated phba->vpi_ids array.
Fix by subtracting the function's base value to get an accurate vpi number.

The file aic79xx_core.c still contains some FreeBSD-specific code/macro
guards, although cross-compatibility was in theory removed with commit
cca6cb8ad7a8 ("scsi: aic7xxx: Fix build using bare-metal toolchain").
Remove it.

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.

dc395x_bios_param was only different from the default when the
CONFIG_SCSI_DC395x_TRMS1040_TRADMAP symbol is true, but that symbol doesn't
exist in the Kconfig system and thus can't be set.

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
(transformation: splitmirror/remirror), ...
otbe = offload_to_be_enabled
oe = offload_enabled

...
T6 - rescan thread has bypassed code to reload new raid map.
...
T7 - event thread runs and sets offload_to_be_enabled
...
T9 - rescan thread turns on offload_enabled.
T10- request comes in and goes down ioaccel path.
T11- BUG_ON.
- After the patch is applied, ioaccel_enabled can only be re-enabled in
the re-scan thread.

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.
