Juno has separate MMU-401 instances in front of the DMA-330, both HDLCD
controllers, the USB host controller, the PCIe root complex, and the
CoreSight ETR. Since there is still work to do to make all the relevant
subsystems interact nicely with the presence of an IOMMU, add the nodes
to aid development and testing but leave them disabled by default to
avoid nasty surprises.

Pull UBI[FS] fixes from Richard Weinberger:
"This contains fixes for issues in both UBI and UBIFS:
- Fallout from the merge window, refactoring UBI code introduced some
issues.
- Fixes for an UBIFS readdir bug which can cause getdents() to busy
loop for ever and a bug in the UBIFS xattr code"
* tag 'upstream-4.9-rc2' of git://git.infradead.org/linux-ubifs:
ubifs: Abort readdir upon error
UBI: Fix crash in try_recover_peb()
ubi: fix swapped arguments to call to ubi_alloc_aeb
ubifs: Fix xattr_names length in exit paths
ubifs: Rename ubifs_rename2

If UBIFS is facing an error while walking a directory, it reports this
error and ubifs_readdir() returns the error code. But the VFS readdir
logic does not make the getdents system call fail in all cases. When the
readdir cursor indicates that more entries are present, the system call
will just return and the libc wrapper will try again since it also
knows that more entries are present.
This causes the libc wrapper to busy loop for ever when a directory is
corrupted on UBIFS.
A common approach do deal with corrupted directory entries is
skipping them by setting the cursor to the next entry. On UBIFS this
approach is not possible since we cannot compute the next directory
entry cursor position without reading the current entry. So all we can
do is setting the cursor to the "no more entries" position and make
getdents exit.

The XTS tweak (or IV) was initialized differently on little endian and
big endian systems. Because the ciphertext depends on the XTS tweak, it
was not possible to use an encrypted filesystem created by a little
endian system on a big endian system and vice versa, even if they shared
the same PAGE_SIZE. Fix this by always using little endian.
This will break hypothetical big endian users of ext4 or f2fs
encryption. However, all users we are aware of are little endian, and
it's believed that "real" big endian users are unlikely to exist yet.
So this might as well be fixed now before it's too late.

The sysfs file /sys/fs/ext4/features/encryption was present on kernels
compiled with CONFIG_EXT4_FS_ENCRYPTION=n. This was misleading because
such kernels do not actually support ext4 encryption. Therefore, only
provide this file on kernels compiled with CONFIG_EXT4_FS_ENCRYPTION=y.
Note: since the ext4 feature files are all hardcoded to have a contents
of "supported", it really is the presence or absence of the file that is
significant, not the contents (and this change reflects that).

- Revert a v4.8 residual overflow change, that breaks sg_inq with

The libfc stack assigns exchange IDs based on the CPU the request
was received on, so we need to send the responses via the same CPU.
Otherwise the send logic gets confuses and responses will be delayed,
causing exchange timeouts on the initiator side.

Not every failure is due to out-of-memory; the ACLs might not be
set, too. So return a detailed error code in ft_sess_create()
instead of just a NULL pointer.

When allocating a new command we should add the pointer to the
debug statements; that allows us to match this with other debug
statements for handling data.

target_sess_cmd_list_waiting() might hit on a condition where
the kref for the command is already 0, but the destructor has
not been called yet (or is stuck in waiting for a spin lock).
Rather than leaving the command on the list we should explicitly
remove it to avoid race issues later on.

target_complete_cmd_with_length"
This reverts commit c1ccbfe0311e2380a6d2dcb0714b36904f5d586f.
Reverting this patch, as it incorrectly assumes the additional length
for INQUIRY in target_complete_cmd_with_length() is SCSI allocation
length, which breaks existing user-space code when SCSI allocation
length is smaller than additional length.
root@scsi-mq:~# sg_inq --len=4 -vvvv /dev/sdb
found bsg_major=253
open /dev/sdb with flags=0x800
inquiry cdb: 12 00 00 00 04 00
duration=0 ms
inquiry: pass-through requested 4 bytes (data-in) but got -28 bytes
inquiry: pass-through can't get negative bytes, say it got none
inquiry: got too few bytes (0)
INQUIRY resid (32) should never exceed requested len=4
inquiry: failed requesting 4 byte response: Malformed response to
SCSI command [resid=32]
AFAICT the original change was not to address a specific host issue,
so go ahead and revert to original logic for now.

This patch addresses a bug where a local EXTENDED_COPY WRITE or READ
backend I/O request would always return SAM_STAT_CHECK_CONDITION,
even if underlying xcopy_pt_cmd->se_cmd generated a different
SCSI status code.
ESX host environments expect to hit SAM_STAT_RESERVATION_CONFLICT
for certain scenarios, and SAM_STAT_CHECK_CONDITION results in
non-retriable status for these cases.
Tested on v4.1.y with ESX v5.5u2+ with local IBLOCK backend copy.

This patch addresses a bug where EXTENDED_COPY across multiple LUNs
results in a CHECK_CONDITION when the source + destination are not
located on the same physical node.
ESX Host environments expect sense COPY_ABORTED w/ COPY TARGET DEVICE
NOT REACHABLE to be returned when this occurs, in order to signal
fallback to local copy method.
As described in section 6.3.3 of spc4r22:
"If it is not possible to complete processing of a segment because the
copy manager is unable to establish communications with a copy target
device, because the copy target device does not respond to INQUIRY,
or because the data returned in response to INQUIRY indicates
an unsupported logical unit, then the EXTENDED COPY command shall be
terminated with CHECK CONDITION status, with the sense key set to
COPY ABORTED, and the additional sense code set to COPY TARGET DEVICE
NOT REACHABLE."
Tested on v4.1.y with ESX v5.5u2+ with BlockCopy across multiple nodes.

This patch fixes a regression in >= v4.1.y code where the original
SCF_ACK_KREF assignment in target_get_sess_cmd() was dropped upstream
in commit 054922bb, but the series for addressing TMR ABORT_TASK +
LUN_RESET with fabric session reinstatement in commit febe562c20 still
depends on this code in transport_cmd_finish_abort().
The regression manifests itself as a se_cmd->cmd_kref +1 leak, where
ABORT_TASK + LUN_RESET can hang indefinately for a specific I_T session
for drivers using SCF_ACK_KREF, resulting in hung kthreads.
This patch has been verified with v4.1.y code.

Userspace should be implementing VPD B0 (Block Limits) to inform the
initiator of max data size, but just in case we do get a too-large request,
do what the spec says and return INVALID_CDB_FIELD.
