48c9579a1a Adding stateid information to tracepoints
Operations to which stateid information is added:
close, delegreturn, open, read, setattr, layoutget, layoutcommit, test_stateid,
write, lock, locku, lockt

Format is "stateid=<seqid>:<crc32 hash stateid.other>", also "openstateid=",
"layoutstateid=", and "lockstateid=" for open_file, layoutget, set_lock
tracepoints.

New function is added to internal.h, nfs_stateid_hash(), to compute the hash

trace_nfs4_setattr() is moved from nfs4_do_setattr() to _nfs4_do_setattr()
to get access to stateid.

trace_nfs4_setattr and trace_nfs4_delegreturn are changed from INODE_EVENT
to new event type, INODE_STATEID_EVENT which is same as INODE_EVENT but adds
stateid information

for locking tracepoints, moved trace_nfs4_set_lock() into _nfs4_do_setlk()
to get access to stateid information, and removed trace_nfs4_lock_reclaim(),
trace_nfs4_lock_expired() as they call into _nfs4_do_setlk() and both were
previously same LOCK_EVENT type.

361cad3c89 nfs: Fix race in __update_open_stateid()
We've seen this in a packet capture - I've intermixed what I
think was going on. The fix here is to grab the so_lock sooner.

1964379 -> #1 open (for write) reply seqid=1
1964393 -> #2 open (for read) reply seqid=2

  __nfs4_close(), state->n_wronly--
  nfs4_state_set_mode_locked(), changes state->state = [R]
  state->flags is [RW]
  state->state is [R], state->n_wronly == 0, state->n_rdonly == 1

1964398 -> #3 open (for write) call -> because close is already running
1964399 -> downgrade (to read) call seqid=2 (close of #1)
1964402 -> #3 open (for write) reply seqid=3

 __update_open_stateid()
   nfs_set_open_stateid_locked(), changes state->flags
   state->flags is [RW]
   state->state is [R], state->n_wronly == 0, state->n_rdonly == 1
   new sequence number is exposed now via nfs4_stateid_copy()

   next step would be update_open_stateflags(), pending so_lock

1964403 -> downgrade reply seqid=2, fails with OLD_STATEID (close of #1)

   nfs4_close_prepare() gets so_lock and recalcs flags -> send close

1964405 -> downgrade (to read) call seqid=3 (close of #1 retry)

   __update_open_stateid() gets so_lock
 * update_open_stateflags() updates state->n_wronly.
   nfs4_state_set_mode_locked() updates state->state

   state->flags is [RW]
   state->state is [RW], state->n_wronly == 1, state->n_rdonly == 1

 * should have suppressed the preceding nfs4_close_prepare() from
   sending open_downgrade

1964406 -> write call
1964408 -> downgrade (to read) reply seqid=4 (close of #1 retry)

   nfs_clear_open_stateid_locked()
   state->flags is [R]
   state->state is [RW], state->n_wronly == 1, state->n_rdonly == 1

1964409 -> write reply (fails, openmode)

a8e326a911 mmc: tegra: implement module external clock change
Allow the the driver to change the clock supplied from the CAR directly,
minimizing the need to divide the clock inside the SDMMC module itself.

This allows for higher clock speeds than the default 48MHz supplied to
the module and is a prerequisite to support DDR signaling modes, where
the Tegra host needs to be run with a fixed internal divider of 2 for
data to be sampled correctly. (Tegra K1 TRM v03p chapter 29.7.1.1)

Also enable the broken preset value quirk as the preset values need to
be adapted to the changed clocking. While Tegra114+ allows this through
vendor registers, there is no such way for Tegra30. Takes the easy way
out  and keep things consistent between the different SoC generations by
flagging the preset registers as unusable.

918f4cbd43 mmc: sdhci: restore behavior when setting VDD via external regulator
After commit 52221610dd ("mmc: sdhci: Improve external VDD regulator
support"), for the VDD is supplied via external regulators, we ignore
the code to convert a VDD voltage request into one of the standard
SDHCI voltage levels, then program it in the SDHCI_POWER_CONTROL. This
brings two issues:

1. SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON quirk isn't handled properly any
more.

2. What's more, once SDHCI_POWER_ON bit is set, some controllers such
as the sdhci-pxav3 used in marvell berlin SoCs require the voltage
levels programming in the SDHCI_POWER_CONTROL register, even the VDD
is supplied by external regulator. So the host in marvell berlin SoCs
still works fine after the commit. However, commit 3cbc6123a9 ("mmc:
sdhci: Set SDHCI_POWER_ON with external vmmc") sets the SDHCI_POWER_ON
bit, this would make the host in marvell berlin SoCs won't work any
more with external vmmc.

This patch restores the behavior when setting VDD through external
regulator by moving the call of mmc_regulator_set_ocr() to the end
of sdhci_set_power() function.

After this patch, the sdcard on Marvell Berlin SoC boards work again.

382c55f88f mmc: block: Allow more than 8 partitions per card
It is quite common for Android devices to utilize more
then 8 partitions on internal eMMC storage.

The vanilla kernel can support this via
CONFIG_MMC_BLOCK_MINORS, however that solution caps the
system to 256 minors total, which limits the number of
mmc cards the system can support.

This patch, which has been carried for quite awhile in
the AOSP common tree, provides an alternative solution
that doesn't seem to limit the total card count. So I
wanted to submit it for consideration upstream.

This patch sets the GENHD_FL_EXT_DEVT flag, which will
allocate minor number in major 259 for partitions past
disk->minors.

It also removes the use of disk_devt to determine devidx
from md->disk. md->disk->first_minor is always initialized
from devidx and can always be used to recover it.

520bd7a8b4 mmc: core: Optimize boot time by detecting cards simultaneously
The mmc workqueue is an ordered workqueue, allowing only one work to
execute per given time. As this workqueue is used for card detection, the
conseqeunce is that cards will be detected one by one waiting for each
other.

Moreover, most of the time spent during card initialization is waiting for
the card's internal firmware to be ready. From a CPU perspective this
typically means waiting for a completion variable to be kicked via an
IRQ-handler or waiting for a sleep timer to finish.

This behaviour of detecting/initializing cards is sub-optimal, especially
for SOCs having several controllers/cards.

Let's convert to use the system_freezable_wq for the mmc detect works.
This enables several works to be executed simultaneously and thus also
cards to be detected like so.

Tests on UX500, which holds two eMMC cards and an SD-card (actually also
an SDIO card, currently not detected), shows a significant improved
behaviour due to this change.

Before this change, both the eMMC cards waited for the SD card to be
initialized as its detect work entered the workqueue first. In some cases,
depending on the characteristic of the SD-card, they got delayed 1-1.5 s.

Additionally for the second eMMC, it needed to wait for the first eMMC to
be initialized which added another 120-190 ms.

Converting to the system_freezable_wq, removed these delays and made both
the eMMC cards available far earlier in the boot sequence.

Selecting the system_freezable_wq, in favour of for example the system_wq,
is because we need card detection mechanism to be disabled once userspace
are frozen during system PM. Currently the mmc core deal with this via PM
notifiers, but following patches may utilize the behaviour of the
system_freezable_wq, to simplify the use of the PM notifiers.

2bcfa6f6e7 bnxt_en: Check hardware resources before enabling NTUPLE.
The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured.  We need to make sure we have the
resources before we enable NTUPLE.  Add bnxt_rfs_capable() to do the
checking.

In addition, we need to do the same checking in ndo_fix_features().  As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.

Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem.  To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

====================
Freescale DPAA FMan

The Freescale Data Path Acceleration Architecture (DPAA) is a set
of hardware components on specific QorIQ multicore processors.
This architecture provides the infrastructure to support
simplified sharing of networking interfaces and accelerators
by multiple CPU cores and the accelerators.

One of the DPAA accelerators is the Frame Manager (FMan)
which contains a series of hardware blocks: ports, Ethernet MACs,
a multi user RAM (MURAM) and Storage Profile (SP).

This patch set introduce the FMan drivers.
Each driver configures and initializes the corresponding
FMan hardware module (described above).
The MAC driver offers support for three different
types of MACs (eTSEC, TGEC, MEMAC).

v9 --> v10:
	- Addressed feedback from David Miller
		Remove private CRC implementation
	- Addressed feedback from Kenneth Klette Jonassen:
		- Use Kernel PHY API to configure dTSEC TBI
		- Use Kernel PHY API to configure mEMAC PCS
		  This patchset requires device tree update:
		  https://patchwork.ozlabs.org/patch/559501/
	- Addressed feedback from Andy Fleming

v8 --> v9:
	No changes

v7 --> v8:
	- Addressed feedback from David Miller

		- Use proper error codes and remove unnecessary prints
		- Use proper values for sleep routines
		- Replace complex Macros with functions
		- Improve device tree processing code
		- Use symbolic defines
		- Add time-out in busy-wait loops
		- Removed exit code (loadable module support will be added later)
	- Fixed "fixed-link" issue raised by Joakim Tjernlund

v1 --> v2:
	- Addressed feedback from Paul Bolle:
		- General feedback of FMan Driver layer
		- Remove Errata defines
		- Aligned comments to Kernel Doc
		- Remove Loadable Module support (not yet supported)

18a6c85fcc fsl/fman: Add FMan Port Support
Add the Data Path Acceleration Architecture Frame Manger Port Driver.
The FMan driver uses a module called "Port" to represent the physical
TX and RX ports.
Each FMan version has different number of physical ports.
This patch adds The FMan Port configuration, initialization and
runtime control routines for both TX and RX.
