Add EXTCON_DISP_DP for the Display external connector. For Type-C
connector the DisplayPort can work as an Alternate Mode(VESA DisplayPort
Alt Mode on USB Type-C Standard). The Type-C support both normal
and flipped orientation, so add a property to extcon.

This patch adds the synchronization extcon APIs to support the notifications
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.
The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().
The list of new extcon APIs as following:
- extcon_sync() : Send the notification for each external connector to
synchronize the information between extcon provider driver
and extcon client driver.
- extcon_set_state_sync() : Set the state of external connector with noti.
- extcon_set_property_sync() : Set the property of external connector with noti.
For example,
case 1, change the state of external connector and synchronized the data.
extcon_set_state_sync(edev, EXTCON_USB, 1);
case 2, change both the state and property of external connector
and synchronized the data.
extcon_set_state(edev, EXTCON_USB, 1);
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS 1);
extcon_sync(edev, EXTCON_USB);
case 3, change the property of external connector and synchronized the data.
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);
extcon_sync(edev, EXTCON_USB);
case 4, change the property of external connector and synchronized the data.
extcon_set_property_sync(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);

pattern
This patch just renames the existing extcon_get/set_cable_state_()
as following because of maintaining the function naming pattern
like as extcon APIs for property.
- extcon_set_cable_state_() -> extcon_set_state()
- extcon_get_cable_state_() -> extcon_get_state()
But, this patch remains the old extcon_set/get_cable_state_() functions
to prevent the build break. After altering new APIs, remove the old APIs.

This patch adds the support of the property capability setting. This function
decides the supported properties of each external connector on extcon provider
driver.
Ths list of new extcon APIs to get/set the capability of property as following:
- int extcon_get_property_capability(struct extcon_dev *edev,
unsigned int id, unsigned int prop);
- int extcon_set_property_capability(struct extcon_dev *edev,

This patch support the extcon property for the external connector
because each external connector might have the property according to
the H/W design and the specific characteristics.
- EXTCON_PROP_USB_[property name]
- EXTCON_PROP_CHG_[property name]
- EXTCON_PROP_JACK_[property name]
- EXTCON_PROP_DISP_[property name]
Add the new extcon APIs to get/set the property value as following:

This patch adds the new extcon type to group the each connecotr
into following five category. This type would be used to handle
the connectors as a group unit instead of a connector unit.
- EXTCON_TYPE_USB : USB connector
- EXTCON_TYPE_CHG : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector
Also, each external connector is possible to belong to one more extcon type.
In caes of EXTCON_CHG_USB_SDP, it have the EXTCON_TYPE_CHG and EXTCON_TYPE_USB.

This patch restrict the usage of extcon_update_state() in the extcon
core because the extcon_update_state() use the bit masking to change
the state of external connector. When this function is used in device drivers,
it may occur the probelm with the handling mistake of bit masking.
Also, this patch removes the extcon_get/set_state() functions because these
functions use the bit masking which is reluctant way. Instead, extcon
provides the extcon_set/get_cable_state_() functions.

Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

Commit abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

The name for a bdi of a gendisk is derived from the gendisk's devt.
However, since the gendisk is destroyed before the bdi it leaves a
window where a new gendisk could dynamically reuse the same devt while a
bdi with the same name is still live. Arrange for the bdi to hold a
reference against its "owner" disk device while it is registered.
Otherwise we can hit sysfs duplicate name collisions like the following:

When a bio is cloned, the newly created bio must be associated with
the same blkcg as the original bio (if BLK_CGROUP is enabled). If
this operation is not performed, then the new bio is not associated
with any group, and the group of the current task is returned when
the group of the bio is requested.
Depending on the cloning frequency, this may cause a large
percentage of the bios belonging to a given group to be treated
as if belonging to other groups (in most cases as if belonging to
the root group). The expected group isolation may thereby be broken.
This commit adds the missing association in bio-cloning functions.

Although dynamic debug is often only used for debug builds, sometimes
its enabled for production builds as well. Minimize its impact by using
jump labels. This reduces the text section by 7000+ bytes in the kernel
image below. It does increase data, but this should only be referenced
when changing the direction of the branches, and hence usually not in
cache.

The current jump_label.h includes bug.h for things such as WARN_ON().
This makes the header problematic for inclusion by kernel.h or any
headers that kernel.h includes, since bug.h includes kernel.h (circular
dependency). The inclusion of atomic.h is similarly problematic. Thus,
this should make jump_label.h 'includable' from most places.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.
This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.
I noticed two cases where config_enabled() is used against a tristate
option:
- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]
- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]
I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

Expose IB diagnostic hardware counters.
The counters count IB events and are applicable for IB and RoCE.
The counters can be divided into two groups, per device and per port.
Device counters are always exposed.
Port counters are exposed only if the firmware supports per port counters.
rq_num_dup and sq_num_to are only exposed if we have firmware support
for them, if we do, we expose them per device and per port.
rq_num_udsdprd and num_cqovf are device only counters.
rq - denotes responder.
sq - denotes requester.

While not an issue now, eventually we will have independent users of
the extable.h file and we will stop sourcing it via module.h header.
In testing that pending work, with very sparse builds, characteristic
of an "allnoconfig" on various architectures, we can sometimes hit an
instance where the very basic standard definitions aren't present,
resulting in:
include/linux/extable.h:26:9: error: 'NULL' undeclared (first use in this function)
To be clear, this isn't a regression, since currently extable.h is
only used by module.h -- however, we will need this addition present
before we start migrating exception table users off module.h and onto
extable.h during the next release cycle.

For historical reasons (i.e. pre-git) the exception table stuff was
buried in the middle of the module.h file. I noticed this while
doing an audit for needless includes of module.h and found core
kernel files (both arch specific and arch independent) were just
including module.h for this.
The converse is also true, in that conventional drivers, be they
for filesystems or actual hardware peripherals or similar, do not
normally care about the exception tables.
Here we fork the exception table content out of module.h into a
new file called extable.h -- and temporarily include it into the
module.h itself.
Then we will work our way across the arch independent and arch
specific files needing just exception table content, and move
them off module.h and onto extable.h
Once that is done, we can remove the extable.h from module.h
and in doing it like this, we avoid introducing build failures
into the git history.
The gain here is that module.h gets a bit smaller, across all
modular drivers that we build for allmodconfig. Also the core
files that only need exception table stuff don't have an include
of module.h that brings in lots of extra stuff and just looks
generally out of place.
