We've recently suffered a rebranding and the Service Provider half of
Parallels has become Odin. This means my email has changed so update
the MAINTAINERS file (and tidy up the pointers to our git trees to be
correct).

The current string_get_size() overflows when the device size goes over
2^64 bytes because the string helper routine computes the suffix from
the size in bytes. However, the entirety of Linux thinks in terms of
blocks, not bytes, so this will artificially induce an overflow on very
large devices. Fix this by making the function string_get_size() take
blocks and the block size instead of bytes. This should allow us to
keep working until the current SCSI standard overflows.
Also fix virtio_blk and mmc (both of which were also artificially
multiplying by the block size to pass a byte side to string_get_size()).
The mathematics of this is pretty simple: we're taking a product of
size in blocks (S) and block size (B) and trying to re-express this in
exponential form: S*B = R*N^E (where N, the exponent is either 1000 or
1024) and R < N. Mathematically, S = RS*N^ES and B=RB*N^EB, so if RS*RB
< N it's easy to see that S*B = RS*RB*N^(ES+EB). However, if RS*BS > N,
we can see that this can be re-expressed as RS*BS = R*N (where R =
RS*BS/N < N) so the whole exponent becomes R*N^(ES+EB+1)

Some implementation of UFS host controller HW might have some non-standard
behaviours (quirks) when compared to behaviour specified by UFSHCI
specification. This patch add support to allow specifying all such quirks
to standard UFS host controller driver so standard driver takes them into
account.
In this change a UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS is introduced,
where a minimum delay of 1ms is required before DME commands for
stability purposes.

Sometimes, specific information about the UFS controller revision is
required in order to determine certain operations or execute
controller dependent quirks.
In order to avoid reading the controller revision multiple times,
we simply read it once and save this information in internal structure.

FA-WWPN port.
For FA-WWPN is enabled port, if NPIV created on that port and,
if port link is brought down, then WWPN was restored from flash for both
physical and NPIV port. This will result in NPIV port and physical port
sharing same WWPN. Any application refreshing ports information will
not be able to scan NPIV port because of this behavior. So while restoring WWPN,
only restore physical port WWPN.

On some vendor switches, when switch port is toggled (down /up),
then in some condition driver tries to configure virtual port,
before FW is actually in ready state to process any commands on wire.
At this time, configuring virtual port can fail. Add fix in driver

Currently, the driver plays off the fact that older sli4 adapters have a
different rpi access pattern that allowed for the rpi reference to be
released earlier in the teardown sequence, allowing the driver to recycle
the rpi value sooner. Newer sli4 adapters have a different access pattern that
requires us to wait for a later mailbox completion. This changes the put
call location on the newer sli4 adapters.
Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

Fix host reset escalation killing all IOs.
SLI-3 adapters will use a new host template. The template differs
from SLI-4 adapters in that it does not have an eh_host_reset_handler.
Lpfc has traditionally never had a host_reset. The host reset
handler was added when we ran into a stuck hardware condition on a
SLI-4 adapter. The host_reset will reset and reinit the pci function,
clearing the hardware condition.
Unfortunately, the host reset handler uses attach/detach code paths,
which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a
host_reset will completely remove the scsi_host from the system. As a
new call to scsi_add_host() is made, the shost# changes, which results
in completely new scsi_devices and device names. All the older scsi
devices on the old shost# are now orphaned and unrecoverable.
We realize we need to re-implement the host_reset_handler so the scsi_host
stays registered across the host_reset, but that will be a rather
lengthy effort. In the short term, we had an immediate need to restore
the SLI-3 devices to their working behavior, with the easiest path being
to remove their host_reset handler.
