Fixes to allow clients to make remove mapping requests, after
they have provided the user space service with the mapping
information, they are using when the service is restarted.
1) Adding IWPM_REG_VALID, IWPM_REG_INCOMPL and IWPM_REG_UNDEF
registration types for the port mapper clients and functions
to set/check the registration type.
2) If the port mapper user space service is not available to register
the client, then its registration stays IWPM_REG_UNDEF and the
registration isn't checked until the service becomes available
(no mappings are possible, if the user space service isn't running).
3) After the service is restarted, the user space port mapper pid is set
to valid and the client registration is set to IWPM_REG_INCOMPL
to allow the client to make remove mapping requests.

mlx4 VFs can provide CQE raw time-stamping services, but they
don't have the hca core clock mapped to their PCI bars.
As such, we should not attempt to query and report the clock offset
to user space for VFs. Doing so causes query_device over VFs to fail
with -ENOSUPP.

Whenever ib_cm gets remove_one call, like when there is a hot-unplug
event, the driver should mark itself as going_down and confirm that no
new works are going to be queued for that device.
so, the order of the actions are:
1. mark the going_down bit.
2. flush the wq.
3. [make sure no new works for that device.]
4. unregister mad agent.
otherwise, works that are already queued can be scheduled after the mad
agent was freed.

In little endian cases, the macro cpu_to_be{16,32,64} unfolds to
__swab{16,32,64} which provides special case for constants. In
big endian cases, __constant_cpu_to_be{16,32,64} and
cpu_to_be{16,32,64} expand directly to the same expression. So,
replace __constant_cpu_to_be{16,32,64} with cpu_to_be{16,32,64}
with the goal of getting rid of the definitions of
__constant_cpu_to_be{16,32,64} completely.
The Coccinelle semantic patch that performs this transformation
is as follows:
@@expression x;@@
(
- __constant_cpu_to_be16(x)
+ cpu_to_be16(x)

- __constant_cpu_to_be32(x)

Persuant to Liran's comments on node_type on linux-rdma
mailing list:
In an effort to reform the RDMA core and ULPs to minimize use of
node_type in struct ib_device, an additional bit is added to
struct ib_device for is_switch (IB switch). This is needed
to be initialized by any IB switch device driver. This is a
NEW requirement on such device drivers which are all
"out of tree".
In addition, an ib_switch helper was added to ib_verbs.h
based on the is_switch device bit rather than node_type
(although those should be consistent).
The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs)
as well as (IPoIB and SRP) ULPs are updated where
appropriate to use this new helper. In some cases,
the helper is now used under the covers of using
rdma_[start end]_port rather than the open coding
previously used.

drm/i915: Readout initial hw mode, v2.
Atomic requires a mode blob when crtc_state->enable is true, or
you get a huge warn_on.
With a few tweaks the mode we read out from hardware could be used
as the real mode without a modeset, but this requires too much
testing, so for now force a modeset the first time the mode blob's
updated.
This preserves the old behavior, because previously we never set
the initial mode, which always meant that a modeset happened
when the mode was first set.

- Add a description in intel_modeset_readout_hw_state of how the
recalculation is done.

This change adds the programming of the MOCS registers to the gen 9+
platforms. The set of MOCS configuration entries introduced by this
patch is intended to be minimal but sufficient to cover the needs of
current userspace - i.e. a good set of defaults. It is expected to be
extended in the future to provide further default values or to allow
userspace to redefine its private MOCS tables based on its demand for
additional caching configurations. In this setup, userspace should
only utilize the first N entries, higher entries are reserved for
future use.
It creates a fixed register set that is programmed across the different
engines so that all engines have the same table. This is done as the
main RCS context only holds the registers for itself and the shared
L3 values. By trying to keep the registers consistent across the
different engines it should make the programming for the registers
consistent.
v2:
-'static const' for private data structures and style changes.(Matt Turner)
v3:
- Make the tables "slightly" more readable. (Damien Lespiau)
- Updated tables fix performance regression.
v4:
- Code formatting. (Chris Wilson)
- re-privatised mocs code. (Daniel Vetter)
v5:
- Changed the name of a function. (Chris Wilson)
v6:

- Added Mesa table entry (skylake & broxton) (Francisco Jerez)
- Tidied up the readability defines (Francisco Jerez)
- NUMBER of entries defines wrong. (Jim Bish)
- Added comments to clear up the meaning of the tables (Jim Bish)
Signed-off-by: Peter Antoine <peter.antoine@intel.com>
v7 (Francisco Jerez):
- Don't write L3-specific MOCS_ESC/SCC values into the e/LLC control
tables. Prefix L3-specific defines consistently with L3_ and
e/LLC-specific defines with LE_ to avoid this kind of confusion in
the future.
- Change L3CC WT define back to RESERVED (matches my hardware
documentation and the original patch, probably a misunderstanding
of my own previous comment).
- Drop Android tables, define new minimal tables more suitable for the
open source stack.
- Add comment that the MOCS tables are part of the kernel ABI.
- Move intel_logical_ring_begin() and _advance() calls one level down

- Minor formatting and style fixes.
v8 (Francisco Jerez):

Using the clone ioctl (or extent_same ioctl, which calls the same extent
cloning function as well) we end up allowing copy an inline extent from
the source file into a non-zero offset of the destination file. This is
something not expected and that the btrfs code is not prepared to deal
with - all inline extents must be at a file offset equals to 0.
For example, the following excerpt of a test case for fstests triggers
a crash/BUG_ON() on a write operation after an inline extent is cloned
into a non-zero offset:
_scratch_mkfs >>$seqres.full 2>&1
_scratch_mount
# Create our test files. File foo has the same 2K of data at offset 4K
# as file bar has at its offset 0.
$XFS_IO_PROG -f -s -c "pwrite -S 0xaa 0 4K" \
-c "pwrite -S 0xbb 4k 2K" \
-c "pwrite -S 0xcc 8K 4K" \
$SCRATCH_MNT/foo | _filter_xfs_io
# File bar consists of a single inline extent (2K size).
$XFS_IO_PROG -f -s -c "pwrite -S 0xbb 0 2K" \
$SCRATCH_MNT/bar | _filter_xfs_io
# Now call the clone ioctl to clone the extent of file bar into file
# foo at its offset 4K. This made file foo have an inline extent at
# offset 4K, something which the btrfs code can not deal with in future
# IO operations because all inline extents are supposed to start at an
# offset of 0, resulting in all sorts of chaos.
# So here we validate that clone ioctl returns an EOPNOTSUPP, which is
# what it returns for other cases dealing with inlined extents.
$CLONER_PROG -s 0 -d $((4 * 1024)) -l $((2 * 1024)) \
$SCRATCH_MNT/bar $SCRATCH_MNT/foo
# Because of the inline extent at offset 4K, the following write made
# the kernel crash with a BUG_ON().
$XFS_IO_PROG -c "pwrite -S 0xdd 6K 2K" $SCRATCH_MNT/foo | _filter_xfs_io
status=0
exit

MIPS32r6 code requires FP64 (ie. FR=1) support. Building a kernel with
support for MIPS32r6 binaries but without support for O32 with FP64 is
therefore a problem which can lead to incorrectly executed userland.
CONFIG_MIPS_O32_FP64_SUPPORT is already selected when the kernel is
configured for MIPS32r6, but not when the kernel is configured for
MIPS64r6 with O32 compat support. Select CONFIG_MIPS_O32_FP64_SUPPORT in
such configurations to prevent building kernels which execute MIPS32r6
userland incorrectly.

Instead of doing ad-hoc checks we already have a way of checking

Only during modesets, or with PIPE_CONFIG_QUIRK_INHERITED_MODE
we should check if a full modeset is really needed.
Fastboot will allow the adjust parameter to ignore some stuff
too, and it will fix up differences in state that are ignored
by the compare function.
Changes since v1:
- Increase the value of the lowest m/n to prevent truncation.
- Dump pipe config when fastboot's used, without a modeset.
- Add adjust parameter to intel_compare_link_m_n, which is
used to adjust m2_n2 if it's a multiple of m_n.
- Add exact parameter intel_compare_m_n.

Use the atomic state instead, this allows removing plane_config
from the crtc after the full hw readout is completed.
The size can be found in the fb, no need for the plane_config.

There's not much point for calculating the changes for the old
state. Instead just disable all scalers when disabling. It's
probably good enough to just disable the crtc_scaler, but just in
case there's a bug disable all scalers.
This means intel_atomic_setup_scalers is only called in the crtc
check function now, so all the transitional code can be removed.

This is probably hard to hit right now because in most cases all
atomic locks are taken, but after conversion to atomic this will make
it more likely to corrupt the crtc->config pointer, resulting in hard
to find bugs.

This warn is harmless, and can be fixed by not calling intel_crtc_disable when

This reverts commit 19ee835cdb0b5a8eb11a68f25a51b8039d564488.
It breaks existing old userspace which doesn't handle UNKNOWN
swizzling correct. Yes UNKNOWN was a thing back in 2009 and probably
still is on some other platforms, but it still pretty clearly broke
the testers machine. If we want this we need to extend the ioctl with
new paramters that only new userspace looks at.

Doesn't really add anything which can't be figured out through

Ux500 is regressing due to commit
a21763a0b1e5a5ab8310f581886d04beadc16616
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

This enumerates the PL011 serial ports on the Ux500. This is
necessary to do if we want to remove one of the serial ports,
since userspace depends on console to be present on ttyAMA2

Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.
The consumers of the regulators this commit affect are the followings:
DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
DCDC2: Core domain
DCDC3: MPU core domain
LDO1: RTC
LDO2: 3v3 IO domain
LDO3: USB-PHY; not a boot-time requirement
LDO4: LCD [16:23]
All but LDO3 need to be always-on for the system to be functional.
Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.

For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter. When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the
panel names for the 'lcd43' and 'lcd35' displays in the device tree
such that they match the names passed by u-boot.
