Pull xfs updates from Darrick Wong:
"xfs: great scads of new stuff for 4.15.
This merge cycle, we're making some substantive changes to XFS. The
in-core extent mappings have been refactored to use proper iterators
and a btree to handle heavily fragmented files without needing
high-order memory allocations; some important log recovery bug fixes;
and the first part of the online fsck functionality.
(The online fsck feature is disabled by default and more pieces of it
will be coming in future release cycles.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported.
New in this version:
- Refactor the incore extent map manipulations to use a cursor
instead of directly modifying extent data.
- Refactor the incore extent map cursor to use an in-memory btree
instead of a single high-order allocation. This eliminates a major
source of complaints about insufficient memory when opening a
heavily fragmented file into a system whose memory is also heavily
fragmented.
- Fix a longstanding bug where deleting a file with a complex
extended attribute btree incorrectly handled memory pointers, which
could lead to memory corruption.
- Improve metadata validation to eliminate crashing problems found
while fuzzing xfs.
- Move the error injection tag definitions into libxfs to be shared
with userspace components.
- Fix some log recovery bugs where we'd underflow log block position
vector and incorrectly fail log recovery.
- Drain the buffer lru after log recovery to force recovered buffers
back through the verifiers after mount. On a v4 filesystem the log
never attaches verifiers during log replay (v5 does), so we could
end up with buffers marked verified but without having ever been
verified.
- Fix various other bugs.
- Introduce the first part of a new online fsck tool. The new fsck
tool will be able to iterate every piece of metadata in the
filesystem to look for obvious errors and corruptions. In the next
release cycle the checking will be extended to cross-reference with
the other fs metadata, so this feature should only be used by the
developers in the mean time"

Currently we rely on the first byte of the Rx buffer to check if there's
any data available to be read. If the first byte of the received buffer
is zero (i.e. null character), then we fail to signal that data is
available even when it's available.
Instead introduce a boolean variable to track the data availability and
update it in the channel receive callback as ready and clear it when the
data is read.

Currently the mailbox framework sets txdone_method to TXDONE_BY_POLL if
the controller sets txdone_by_poll. However some clients can have a
mechanism to do TXDONE_BY_ACK which they can specify by knows_txdone.
However, we endup setting both TXDONE_BY_POLL and TXDONE_BY_ACK in that
case. In such scenario, we may end up with below warnings as the tx
ticker is run both by mailbox framework and the client.

The LPI transitioning logic in stmmac_main uses
priv->tx_path_in_lpi_mode to enter/exit LPI.
However, priv->tx_path_in_lpi_mode is assigned
using the return value from host_irq_status().
So for dwmac4, priv->tx_path_in_lpi_mode was always false,
so stmmac_tx_clean() would always try to put us in eee mode,
and stmmac_xmit() would never take us out of eee mode.
To fix this, make host_irq_status() read and return the LPI
irq status also for dwmac4.
This also increments the existing LPI counters, so that
ethtool --statistics shows LPI transitions also for dwmac4.
For dwmac1000, irqs are enabled/disabled using the register
named "Interrupt Mask Register", and thus setting a bit disables
that specific irq.
For dwmac4 the matching register is named "MAC_Interrupt_Enable",
and thus setting a bit enables that specific irq.
Looking at dwmac1000_core.c, the irqs that are always enabled are:
LPI and PMT.
Looking at dwmac4_core.c, the irqs that are always enabled are:
PMT.
To be able to read the LPI irq status, we need to enable the LPI
irq also for dwmac4.

The mvneta controller provides a 8-bit register to update the pending
Tx descriptor counter. Then, a maximum of 255 Tx descriptors can be
added at once. In the current code the mvneta_txq_pend_desc_add function
assumes the caller takes care of this limit. But it is not the case. In
some situations (xmit_more flag), more than 255 descriptors are added.
When this happens, the Tx descriptor counter register is updated with a
wrong value, which breaks the whole Tx queue management.
This patch fixes the issue by allowing the mvneta_txq_pend_desc_add
function to process more than 255 Tx descriptors.
