This patch fixes a bug with tcm_loop where performing a scsi_host rescan was
causing an oops due to a received scsi_cmnd->device->id value not matching a
previously configured tcm_loop_tpg entry in tcm_loop_hba->tl_hba_tpgs[]
obtained from within tcm_loop_queuecommand() code.
This fix adds an explict check for tcm_loop_tpg->tl_hba in order to ensure
tcm_loop_make_naa_tpg() has already been invoked to initialize a given
tcm_loop_tpg entry, and also adds an explict clear of tcm_loop_tpg->tl_hba
from within the tcm_loop_drop_naa_tpg() release path.
This bug was manifesting itself with the following OOPs:

This patch removes the legacy device active I/O shutdown code that was
originally called from transport_processing_thread() context during shutdown
including transport_processing_shutdown() and transport_release_all_cmds().
This is due to the fact that in modern configfs control plane code by the
time shutdown of an se_device instance in transport_processing_thread()
is allowed to occur via:
rmdir /sys/kernel/config/target/core/$HBA/$DEV
all active I/O will already have been ceased while removing active configfs
fabric Port/LUN symlinks. Eg: the removal of an active se_device is protected
by inter-module VFS references from active Port/LUN symlinks.
Two WARN_ON() checks have been added in their place before exiting
transport_processing_thread() to watch out for any leaked descriptors.

This patch removes a number of SCF_SE_LUN_CMD flag abuses within iscsi-target
code to determine when iscsit_release_cmd() or transport_generic_free_cmd()
should be called while releasing an individual iscsi_cmd descriptor.
In the place of SCF_SE_LUN_CMD checks, this patch converts existing code to
use a new iscsit_free_cmd() that inspects iscsi_cmd->iscsi_opcode types to
determine which of the above functions should be invoked. It also removes the
now unnecessary special case checking in iscsit_release_commands_from_conn().

This patch converts se_cmd->transport_wait_for_tasks(se_cmd, 1) usage to use
transport_generic_free_cmd() directly in target-core and iscsi-target fabric
usage. The includes:
*) Removal of the optional transport_generic_free_cmd() call from within
transport_generic_wait_for_tasks()
*) Usage of existing SCF_SUPPORTED_SAM_OPCODE to determine when
transport_generic_wait_for_tasks() processing may occur instead of
checking se_cmd->transport_wait_for_tasks()
*) Move transport_generic_wait_for_tasks() call ahead of core_dec_lacl_count()
and transport_lun_remove_cmd() in transport_generic_free_cmd() to follow
existing logic for iscsi-target w/ se_cmd->transport_wait_for_tasks(se_cmd, 1)
*) Removal of se_cmd->transport_wait_for_tasks() function pointer
*) Rename transport_generic_wait_for_tasks() -> transport_wait_for_tasks(), and
add docbook comment.
*) Add EXPORT_SYMBOL for transport_wait_for_tasks()
For the case in iscsi_target_erl2.c:iscsit_prepare_cmds_for_realligance()
where se_cmd->transport_wait_for_tasks(se_cmd, 0) is called, this patch
adds a direct call to transport_wait_for_tasks().

Testing in_interrupt() to know when sleeping is allowed is not really
reliable (since eg it won't be true if the caller is holding a spinlock).
Instead have the caller tell core_tmr_alloc_req() what GFP_xxx to use;
every caller except tcm_qla2xxx can use GFP_KERNEL.

Inline two simple functions only used by it, and replace a goto
with a simple if else construct.
Note that the code moved from transport_dec_and_check seems fairly
buggy - the atomic_read check on a variable where we'd do an
atomic_dec_and_test looks racy if we'll ever get someone increment
it without the lock held around them (which it looks like we do),
and not decrementing the second counter if the first one doesn't
hit zero also at least needs an explanation.

This patch is a re-orginzation of core_tmr_lun_reset() logic to properly
scan the active tmr_list, dev->state_task_list and qobj->qobj_list w/ the
relivent locks held, and performing a list_move_tail onto seperate local
scope lists before performing the full drain.
This involves breaking out the code into three seperate list specific
functions: core_tmr_drain_tmr_list(), core_tmr_drain_task_list() and
core_tmr_drain_cmd_list().

This patch addresses a bug with the lio-core-2.6.git conversion of
transport_add_cmd_to_queue() to use a single embedded list_head, instead
of individual struct se_queue_req allocations allowing a single se_cmd to
be added to the queue mulitple times. This was changed in the following:
commit 2a9e4d5ca5d99f4c600578d6285d45142e7e5208
Author: Andy Grover <agrover@redhat.com>
Date: Tue Apr 26 17:45:51 2011 -0700
target: Embed qr in struct se_cmd
The problem is that some target code still assumes performing multiple
adds is allowed via transport_add_cmd_to_queue(), which ends up causing
list corruption in qobj->qobj_list code. This patch addresses this
by removing an existing struct se_cmd from the list before the add, and
removes an unnecessary list walk in transport_remove_cmd_from_queue()
It also changes cmd->t_transport_queue_active to use explict sets intead
of increment/decrement to prevent confusion during exception path handling.

A couple of changes to the Tegra maintainership setup:
I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.
Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.
Finally, update the git URL since I'll take over running the main repo
for a while.
Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).

In summary, this DMI quirk uses the _CRS info by default for the ASUS
M2V-MX SE by turning on `pci=use_crs` and is similar to the quirk
added by commit 2491762cfb47 ("x86/PCI: use host bridge _CRS info on
ASRock ALiveSATA2-GLAN") whose commit message should be read for further
information.
Since commit 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci

Trusting the ACPI _CRS information (`pci=use_crs`) fixes this problem.
$ dmesg | grep -i crs # with the quirk
PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
The match has to be against the DMI board entries though since the vendor entries are not populated.
DMI: System manufacturer System Product Name/M2V-MX SE, BIOS 0304 10/30/2007
This quirk should be removed when `pci=use_crs` is enabled for machines
from 2006 or earlier or some other solution is implemented.
Using coreboot [1] with this board the problem does not exist but this
quirk also does not affect it either. To be safe though the check is
tightened to only take effect when the BIOS from American Megatrends is
used.
15:13 < ruik> but coreboot does not need that
15:13 < ruik> because i have there only one root bus
15:13 < ruik> the audio is behind a bridge

This resolves a regression seen by some users of bridging.
Some users use the bridge like a dummy device.
They expect to be able to put an IPv6 address on the device
with no ports attached. Although there are better ways of doing
this, there is no reason to not allow it.
Note: the bridge still will reflect the state of ports in the
bridge if there are any added.

The encoders are supposedly fully routeable, but changing the mapping
doesn't always seem to take. Using a hardcoded mapping is much more
reliable.

The HPD pin is not reliable for detecting whether a monitor
is connected or not. Skip HPD and just use DDC or load
detection.
