The call to debugfs_remove_recursive(qp->debugfs_dir) of the sub-level
directory must not be later than
debugfs_remove_recursive(nt_debugfs_dir) of the top-level directory.
Otherwise, the sub-level directory will not exist, and it would be
invalid (panic) to attempt to remove it. This removes the top-level
directory last, after sub-level directories have been cleaned up.

10GbE Intel Wired LAN Driver Updates 2017-02-16
This series contains updates to ixgbe only.
Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter
supports it.
Stephen Hemminger renames our dcbnl_ops since it is global to
ixgbe_dcbnl_ops to avoid namespace issues.
Mark updates the driver version based on the recent changes.
Alex has the remainder of the changes, starting with consolidating
functions that represent logical steps in the receive process so we can
later update them more easily (and align with igb). Modify the receive
path to only synchronize the length of the frame versus the entire buffer.
Provided performance improvements by adding support for
DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional
performance gains by batching the page count updates instead of doing
them one at a time. Adjusted the receive path to use 3k buffers with
8k backing them in order to support build_skb with jumbo frames. Made
additional driver improvements by using the length of the packet instead
of the DD status to determine if a new descriptor is ready to be
processed, which cuts down on reads. To reduce code duplication, pulled
apart the receive path into separate functions. Added support for
providing a buffer with headroom and tailroom to allow for shared info
for NET_SKB_PAD and NET_IP_ALIGN.

In various places we currently assert that xfs_bmap_btalloc allocates
from the same as the firstblock value passed in, unless it's either
NULLAGNO or the dop_low flag is set. But the reflink code does not
fully follow this convention as it passes in firstblock purely as
a hint for the allocator without actually having previous allocations
in the transaction, and without having a minleft check on the current
AG, leading to the assert firing on a very full and heavily used
file system. As even the reflink code only allocates from equal or
higher AGs for now we can simply the check to always allow for equal
or higher AGs.
Note that we need to eventually split the two meanings of the firstblock
value. At that point we can also allow the reflink code to allocate
from any AG instead of limiting it in any way.

When block size is larger than inode cluster size, the call to
XFS_B_TO_FSBT(mp, mp->m_inode_cluster_size) returns 0. Also, mkfs.xfs
would have set xfs_sb->sb_inoalignmt to 0. This causes
xfs_ialloc_cluster_alignment() to return 0. Due to this
args.minalignslop (in xfs_ialloc_ag_alloc()) gets the unsigned
equivalent of -1 assigned to it. This later causes alloc_len in
xfs_alloc_space_available() to have a value of 0. In such a scenario
when args.total is also 0, the assert statement "ASSERT(args->maxlen >
0);" fails.
This commit fixes the bug by replacing the call to XFS_B_TO_FSBT() in
xfs_ialloc_cluster_alignment() with a call to xfs_icluster_size_fsb().

The block reservation for the transaction allocated in
xfs_shift_file_space() is an artifact of the original collapse range
support. It exists to handle the case where a collapse range occurs,
the initial extent is left shifted into a location that forms a
contiguous boundary with the previous extent and thus the extents
are merged. This code was subsequently refactored and reused for
insert range (right shift) support.
If an insert range occurs under low free space conditions, the
extent at the starting offset is split before the first shift
transaction is allocated. If the block reservation fails, this
leaves separate, but contiguous extents around in the inode. While
not a fatal problem, this is unexpected and will flag a warning on
subsequent insert range operations on the inode. This problem has
been reproduce intermittently by generic/270 running against a
ramdisk device.
Since right shift does not create new extent boundaries in the
inode, a block reservation for extent merge is unnecessary. Update
xfs_shift_file_space() to conditionally reserve fs blocks for left
shift transactions only. This avoids the warning reproduced by
generic/270.

Certain workoads that punch holes into speculative preallocation can
cause delalloc indirect reservation splits when the delalloc extent is
split in two. If further splits occur, an already short-handed extent
can be split into two in a manner that leaves zero indirect blocks for
one of the two new extents. This occurs because the shortage is large
enough that the xfs_bmap_split_indlen() algorithm completely drains the
requested indlen of one of the extents before it honors the existing
reservation.
This ultimately results in a warning from xfs_bmap_del_extent(). This
has been observed during file copies of large, sparse files using 'cp
--sparse=always.'
To avoid this problem, update xfs_bmap_split_indlen() to explicitly
apply the reservation shortage fairly between both extents. This smooths
out the overall indlen shortage and defers the situation where we end up
with a delalloc extent with zero indlen reservation to extreme
circumstances.

When a delalloc extent is created, it can be merged with pre-existing,
contiguous, delalloc extents. When this occurs,
xfs_bmap_add_extent_hole_delay() merges the extents along with the
associated indirect block reservations. The expectation here is that the
combined worst case indlen reservation is always less than or equal to
the indlen reservation for the individual extents.
This is not always the case, however, as existing extents can less than
the expected indlen reservation if the extent was previously split due
to a hole punch. If a new extent merges with such an extent, the total
indlen requirement may be larger than the sum of the indlen reservations
held by both extents.
xfs_bmap_add_extent_hole_delay() assumes that the worst case indlen
reservation is always available and assigns it to the merged extent
without consideration for the indlen held by the pre-existing extent. As
a result, the subsequent xfs_mod_fdblocks() call can attempt an
unintentional allocation rather than a free (indicated by an ASSERT()
failure). Further, if the allocation happens to fail in this context,
the failure goes unhandled and creates a filesystem wide block
accounting inconsistency.
Fix xfs_bmap_add_extent_hole_delay() to function as designed. Cap the
indlen reservation assigned to the merged extent to the sum of the
indlen reservations held by each of the individual extents.

A debug mode write failure mechanism was introduced to XFS in commit
801cc4e17a ("xfs: debug mode forced buffered write failure") to
facilitate targeted testing of delalloc indirect reservation management
from userspace. This code was subsequently rendered ineffective by the
move to iomap based buffered writes in commit 68a9f5e700 ("xfs:
implement iomap based buffered write path"). This likely went unnoticed
because the associated userspace code had not made it into xfstests.
Resurrect this mechanism to facilitate effective indlen reservation
testing from xfstests. The move to iomap based buffered writes relocated
the hook this mechanism needs to return write failure from XFS to
generic code. The failure trigger must remain in XFS. Given that
limitation, convert this from a write failure mechanism to one that
simply drops writes without returning failure to userspace. Rename all
"fail_writes" references to "drop_writes" to illustrate the point. This
is more hacky than preferred, but still triggers the XFS error handling
behavior required to drive the indlen tests. This is only available in
DEBUG mode and for testing purposes only.

The buffered write failure handling code in
xfs_file_iomap_end_delalloc() has a couple minor problems. First, if
written == 0, start_fsb is not rounded down and it fails to kill off a
delalloc block if the start offset is block unaligned. This results in a
lingering delalloc block and broken delalloc block accounting detected
at unmount time. Fix this by rounding down start_fsb in the unlikely
event that written == 0.
Second, it is possible for a failed overwrite of a delalloc extent to
leave dirty pagecache around over a hole in the file. This is because is
possible to hit ->iomap_end() on write failure before the iomap code has
attempted to allocate pagecache, and thus has no need to clean it up. If
the targeted delalloc extent was successfully written by a previous
write, however, then it does still have dirty pages when ->iomap_end()
punches out the underlying blocks. This ultimately results in writeback
over a hole. To fix this problem, unconditionally punch out the
pagecache from XFS before the associated delalloc range.

- Conditionally request some warning options not available on clang
- Set the maximum optimization level to -O3 when using CC=clang, leave
the previous setting of -O6 otherwise.
- Make it an error to pass a signed value to OPTION_UINTEGER, so that
we can remove abs(unsigned int) calls in 'perf bench futex'.
- Make sure dprintf() is not defined before using that name in 'perf bench numa'
- Avoid using field after variable sized type, its a GNU extension, use
equivalent code.
- Fix some bugs where some variables could be used unitialized,
something not caught by gcc.
- Fix some spots where we were testing struct->array[] members against
NULL, it will always evaluate to 'true'.
- Add missing parse_events_error() prototype in the bison file.

Declare dm_space_map structures as const as they are only passed as an
argument to the function memcpy. This argument is of type const void *,
so dm_space_map structures having this property can be declared as
const.

Since we have the MST feature enabled and Pin-Port mux for user to
select the converter routing, multiple port mapping to same converter
needs to be supported.
To support multiple port mapped to same converter following changes are
done for this:.
o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

To enable stream on a specific port of a MST capable pin, the port
needs to be selected before we configure the pin widget verb.
When port is selected, all the pin widget verb controlling the sink
device operation will be directed to selected port. So add port
selection before configuring the pin widget verb.

The ELD notification can be received asynchronously from the graphics
side and this may happen just at the moment the sound driver is
initializing and notification will be missed. Similarly at system
resume, the notification is ignored as the ELD and connection states
are updated in anyway at the end of the resume.
So check the jack status in boot/resume by querying the port presence
based on pin caps and report the jack status.

To support DP MST audio, new pin verbs/params are added. This patch
adds helper functions to do following:
o To set a specific port
o To get the currently selected port
o To get the length of port.
