Since we're setting the host port type now to FC_PORTTYPE_NPIV
for adapters running in NPIV mode we should allow this port type
for auto-port scanning as well.

Update driver version to 8.3.1
Also update copyright end year for driver.
Signed-off-by: James Smart <James.Smart@emulex.com>
Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
8.3.1 Fixes/Changes :
- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
caused LUNs to not be discovered on big-endian (e.g. PPC)
- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)
- Make lpfc_debugfs_mask_disc_trc static (sparse)
- Correct misspelled word BlockGuard in lpfc_logmsg.h comment
- Replaced repeated code segment for canceling IOCBs from a list with
a function call, lpfc_sli_cancel_iocbs().
- Increased HBQ buffers to support 40KB SSC sequences.
- Added sysfs interface to update speed and topology parameter without
link bounce.
- Fixed bug with sysfs fc_host WWNs not being updated after changing
the WWNs.
- Check if the active mailbox is NULL in the beginning of the mailbox
timeout handler - fixes panic in the mailbox timeout handler while
running IO stress test
- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
reference to phba through vport
- Removed de-reference of scsi device after call to scsi_done() to fix
panic in scsi completion path while accessing scsi device after
scsi_done is called.
- Fixed "Nodelist not empty" message when unloading the driver after
target reboot test
- Added LP2105 HBA model description
- Added code to print all 16 words of unrecognized ASYNC events
- Fixed memory leak in vport create + delete loop
- Added support for handling dual error bit from HBA
- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb
- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node
- Take NULL termintator into account when calculating available buffer space

blk_rq_unmap_user() returns EFAULT if a program passes an invalid
address to kernel (the kernel fails to copy data to user space). sg
needs to pass the returned value to user space instead of ignoring
it. Before the block layer conversion, sg returns EFAULT
properly. This restores the old behavior.

So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all. The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media. In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.
My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

For windows compatibility,
1) On a port protection violation, simply ignore the request and
do not return an exception (allow the control method to continue execution.)
2) If only part of the request overlaps a protected port,
read/write the individual ports that are not protected.

This fixes an inconsistent behaviour when loading the driver with the

When resuming from standby (on a laptop) I see the following message in

"ACPI: EC: non-query interrupt received, switching to interrupt mode"
This apparently prevented sony-laptop to properly restore the brightness
level on resume.
The cause: In drivers/acpi/ec.c the acpi_ec_suspend function clears the
GPE mode bit, but this is not restored in acpi_ec_resume (the function
below it). The patch below fixes this by properly restoring the GPE_MODE
bit. Tested and confirmed to work.

Linux tells ICH4 users that they can (manually) invoke
"hpet=force" to enable the undocumented ICH-4M HPET.
The HPET becomes available for both clocksource and clockevents.
But as of ff69f2bba6
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
the HPET may be used via clocksource for idle accounting, and
hpet=force on an ICH4 box hangs boot.
It turns out that touching the MMIO HPET withing
the ARB_DIS part of C3 will hang the hardware.
The fix is to simply move the timer access outside
the ARB_DIS region. This is a no-op on modern hardware
because ARB_DIS is no longer used.

Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed. This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.
Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.
