We can request task management IOCTL command(MPI2_FUNCTION_SCSI_TASK_MGMT)
to /dev/mpt3ctl.  If the given task_type is either abort task or query
task, it may need a field named "Initiator Port Transfer Tag to Manage" in
the IU.

Current code does not support to check target IPTT tag from the tm_request.
This patch introduces to check TaskMID given from the userspace as a target
tag.  We have a rule of relationship between
(struct request *req->tag) and smid in mpt3sas_base.c:

3318 u16
3319 mpt3sas_base_get_smid_scsiio(struct MPT3SAS_ADAPTER *ioc, u8 cb_idx,
3320         struct scsi_cmnd *scmd)
3321 {
3322         struct scsiio_tracker *request = scsi_cmd_priv(scmd);
3323         unsigned int tag = scmd->request->tag;
3324         u16 smid;
3325
3326         smid = tag + 1;

So if we want to abort a request tagged #X, then we can pass (X + 1) to
this IOCTL handler.  Otherwise, user space just can pass 0 TaskMID to abort
the first outstanding smid which is legacy behaviour.

This patch is to change msleep() to usleep_range() based on
Documentation/timers/timers-howto.txt. It suggests using usleep_range()
for small msec(1ms - 20ms) since msleep() will often sleep longer than
desired value.

After changing, booting time will be 5ms-10ms faster than before.  I
tested this change on two different platforms, one has 5ms faster, another
one is about 10ms. I think this is different on different platform.

Actually, from UFS host side, 1ms-5ms delay is already sufficient for its
initialization of the local UIC layer.

This allows a list of requests to be issued, with the LLD only writing the
hardware doorbell when necessary, after the last request was prepared.
This is more efficient if we have lists of requests to issue, particularly
on virtualized hardware, where writing the doorbell is more expensive than
on real hardware.

The use case for this is plugged IO, where blk-mq flushes a batch of
requests all at once.

The API is the same as for blk-mq, just with blk-mq concepts tweaked to
fit the SCSI subsystem API: the "last" flag in blk_mq_queue_data becomes a
flag in scsi_cmnd, while the queue_num in the commit_rqs callback is
extracted from the hctx and passed as a parameter.

The only complication is that blk-mq uses different plugging heuristics
depending on whether commit_rqs is present or not.  So we have two
different sets of blk_mq_ops and pick one depending on whether the
scsi_host template uses commit_rqs or not.

there are some "non-interrupt-based" errors or events which need history
to improve debugging or help know the health status of UFS devices.

Example of fatal errors:

 - Link startup error

 - Suspend error

 - Resume error

Example of abnormal events:

 - Task or request abort

 - Device reset (now equals to Logical Unit Reset)

 - Host reset

The Aspeed pinctl schema have errors in the 'compatible' schema:

Documentation/devicetree/bindings/pinctrl/aspeed,ast2400-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2400-pinctrl', 'aspeed', 'g4-pinctrl'] has non-unique elements
Documentation/devicetree/bindings/pinctrl/aspeed,ast2500-pinctrl.yaml: \
properties:compatible:enum: ['aspeed', 'ast2500-pinctrl', 'aspeed', 'g5-pinctrl'] has non-unique elements

Flow style sequences have to be quoted if the vales contain ','. Fix
this by using the more common one line per entry formatting.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Properties which are child node definitions need to have an explict
type. Otherwise, a matching (DT) property can silently match when an
error is desired. Fix this up tree-wide. Once this is fixed, the
meta-schema will enforce this on any child node definitions.

Pull x86 fixes from Thomas Gleixner:
 "A set of x86 specific fixes and updates:

   - The CR2 corruption fixes which store CR2 early in the entry code
     and hand the stored address to the fault handlers.

   - Plug a memory leak in the boot code.

   - Make the Hyper-V assist functionality robust by zeroing the shadow
     page.

   - Remove a useless check for dead processes with LDT

   - Update paravirt and VMware maintainers entries.
