The status reported directly by the battery controller is not always
reliable and should be corrected based on the current draw information.
This implements such a correction with a dedicated function, called
where the supply status is retrieved.

A mechanism to ignore the first external power change notification was
put in place years ago to ignore the power_supply_register notification.
However, this doesn't apply to the current situation anymore, as the
first notification is always the result of a legitimate power change.
This removes this deprecated mechanism, which puts back the driver's
state machine to a sane state (an ignored first notification previously
caused a charging/discharging status inversion).

The max17042 is intended for Li-Ion or Li-Po batteries, add a TECHNOLOGY
attribute to reflect this. Note this is hardcoded to Li-Ion as there is
no way to tell the difference, and Lithium-Ion Polymer batteries are
a sub-family of Lithium-Ion so Li-Ion technically is correct for both.
Using Li-Ion for both is already done by many drivers and is much
better then not providing any technology info at all.

Userspace prefers the driver having a status property over having to guess
itself. Specifically this will properly make the GNOME3 UI (and likely
others) properly show discharging / charging / full status, instead
of always showing discharging as status.
Note that in the case there is no charger driver supplying the max17042,
then a status of unknown will get returned. At least upower treats
this the same as not having a status attribute, so in this case nothing
changes from a userspace pov.

Some x86 machines use a max17047 fuel-gauge and x86 might be missing
platform_data if not provided by SFI.
This commit adds default platform_data as fallback option so that the
driver can work on boards where no platform_data is provided.
Since not all boards have a thermistor hooked up, set temp_min to 0 and
change the health checks from temp <= temp_min to temp < temp_min to
not trigger on such boards (where temp reads 0).

When using dmatest with sg_buffers=128 I stumbled upon the problem, that
the "map_cnt" variable of "struct dmaengine_unmap_data" was set to 0.
"map_cnt" is an "u8" variable, resulting in an overrun when its
value is set to src_cnt + dst_cnt, to twice the sg_buffer value.
This patch adds a small check to dmatest, so that this confusing error
is detected and the test is aborted.

features in charger
The driver was registering two classes, bq24190-battery & -charger.
Because the power supply framework cannot surface features from multiple
drivers in a single class, a fuel gauge driver would create a third class,
which some power management utilities cannot see.
Deprecate the -battery class for future removal and replicate its features
in -charger. Set /sys/class...-charger/online = pg_stat && !batfet_disable.
If device_property "omit-battery-class" is set, don't register -battery.

no suppliers
It is sensible to assume that the hardware actually always has a
way of charging the battery so when power_supply_am_i_supplied does not
find any suppliers, that does not mean that there are none, but simply
that no power_supply-drivers are registered / bound for any suppliers for
the supply calling power_supply_am_i_supplied.
At which point a fuel-gauge driver calling power_supply_am_i_supplied()
cannot determine whether the battery is being charged or not.
Allow a caller of power_supply_am_i_supplied to differentiate between
there not being any suppliers, vs no suppliers being online by returning
-ENODEV if there are no suppliers matching supplied_to / supplied_from,
which allows fuel-gauge drivers to return POWER_SUPPLY_STATUS_UNKNOWN
rather then POWER_SUPPLY_STATUS_DISCHARGING if there are no suppliers.

We can't assume that the battery is or stays present after probing
on devices with replaceable battery.
On some devices (e.g. GTA04 or OpenPanodra) it can be removed
and even be hot swapped by the user while device continues to operate
through external AC or USB power (as long as system power consumption
remains below ca. 500mA as provided by USB). Under certain conditions
it is possible to boot without battery.
So it makes no sense to check for this situation during probe and make
the charger driver (and its status reports) completely non-operational if
the battery can be inserted later.
Tested on: GTA04 and OpenPandora.

Allow platform-code to disable the reset on probe and suspend/resume
by setting a "disable-reset" boolean device property on the device.
There are several reasons why the platform-code may want to disable
the reset on probe and suspend/resume:
1) Resetting the charger should never be necessary it should always have
sane values programmed. If it is running with invalid values while we
are not running (system turned off or suspended) there is a big problem
as that may lead to overcharging the battery.
2) The reset in suspend() is meant to put the charger back into default
mode, but this is not necessary and not a good idea. If the charger has
been programmed with a higher max charge_current / charge_voltage then
putting it back in default-mode will reset those to the safe power-on
defaults, leading to slower charging, or charging to a lower voltage
(and thus not using the full capacity) while suspended which is
undesirable. Reprogramming the max charge_current / charge_voltage
after the reset will not help here as that will put the charger back
in host mode and start the i2c watchdog if the host then does not do
anything for 40s (iow if we're suspended for more then 40s) the watchdog
expires resetting the device to default-mode, including resetting all
the registers to there safe power-on defaults. So the only way to keep
using custom charge settings while suspending is to keep the charger in
its normal running state with the i2c watchdog disabled. This is fine
as the charger will still automatically switch from constant current
to constant voltage and stop charging when the battery is full.
3) Besides never being necessary resetting the charger also causes
problems on systems where the charge voltage limit is set higher then the
reset value, if this is the case and the charger is reset while charging
and the battery voltage is between the 2 voltages, then about half the
time the charger gets confused and claims to be charging (REG08 contains
0x64) but in reality the charger has decoupled itself from VBUS (Q1 off)
and is drawing 0A from VBUS, leaving the system running from the battery.
This last problem is happening on a GPD-win mini PC with a bq24292i
charger chip combined with a max17047 fuel-gauge and a LiHV battery.
I've checked and TI does not list any errata for the bq24292i which
could explain this (there are no errata at all).

reference to fix pmem crash
The x86 conversion to the generic GUP code included a small change which causes
crashes and data corruption in the pmem code - not good.
The root cause is that the /dev/pmem driver code implicitly relies on the x86
get_user_pages() implementation doing a get_page() on the page refcount, because
get_page() does a get_zone_device_page() which properly refcounts pmem's separate
page struct arrays that are not present in the regular page struct structures.
(The pmem driver does this because it can cover huge memory areas.)
But the x86 conversion to the generic GUP code changed the get_page() to
page_cache_get_speculative() which is faster but doesn't do the
get_zone_device_page() call the pmem code relies on.
One way to solve the regression would be to change the generic GUP code to use
get_page(), but that would slow things down a bit and punish other generic-GUP
using architectures for an x86-ism they did not care about. (Arguably the pmem
driver was probably not working reliably for them: but nvdimm is an Intel
feature, so non-x86 exposure is probably still limited.)
So restructure the pmem code's interface with the MM instead: get rid of the
get/put_zone_device_page() distinction, integrate put_zone_device_page() into
__put_page() and and restructure the pmem completion-wait and teardown machinery:
Kirill points out that the calls to {get,put}_dev_pagemap() can be
removed from the mm fast path if we take a single get_dev_pagemap()
reference to signify that the page is alive and use the final put of the
page to drop that reference.
This does require some care to make sure that any waits for the
percpu_ref to drop to zero occur *after* devm_memremap_page_release(),
since it now maintains its own elevated reference.
This speeds up things while also making the pmem refcounting more robust going
forward.

The bnx2x driver is not providing proper alignment on the receive buffers it
passes to build_skb(), causing skb_shared_info to be misaligned.
skb_shared_info contains an atomic, and while PPC normally supports
unaligned accesses, it does not support unaligned atomics.
Aligning the size of rx buffers will ensure that page_frag_alloc() returns
aligned addresses.
This can be reproduced on PPC by setting the network MTU to 1450 (or other
non-multiple-of-4) and then generating sufficient inbound network traffic
(one or two large "wget"s usually does it), producing the following oops:

In the hip06 and hip07 SoCs, phy connect to mdio bus.The mdio
module is probed with module_init, and, as such,
is not guaranteed to probe before the HNS driver. So we need
to support deferred probe.
We check for probe deferral in the mac init, so we not init DSAF
when there is no mdio, and free all resource, to later learn that
we need to defer the probe.

For legacy reasons NFP FW may be compiled to DMA packets to a constant
offset into the buffer and use the space before it for metadata. This
ensures that packets data always start at a certain offset regardless of
the amount of preceding metadata.
If rx offset is set to 0 there may still be up to 64 bytes of metadata
but metadata will start at the beginning of the buffer, instead of:
data_start_offset = rx_offset - meta_len
Even though we make the buffers larger to accommodate up to 64 bytes of
metadata, if there is only N bytes of metadata, we will end up with
N bytes of headroom and 64 - N bytes of tailroom. Therefore we can't
rely on that space for XDP headroom. Make sure we always allocate
full 256 bytes. This, unfortunately, means we can't fit the headroom
on an u8 any more.

Right now the required Service Process ABI version is still tied
to max ID of known commands. For new NSP commands we are adding
we are checking if NSP version is recent enough on command-by-command
basis. The driver doesn't have to force the device to have the
very latest flash, anything newer than 0.8 should do.

Reading TX queue indexes from the device memory on each interrupt
is expensive. It's doubly expensive with XDP running since we have
two TX rings to check there. If the software indexes indicate that
the TX queue is completely empty, however, we don't need to look at
the device completion index at all.
The queuing CPU is doing a wmb() before kicking the device TX so
we should be safe to assume on the CPU handling the completions will
never see old value of the software copy of the index.

On the RX path we follow the "drop if allocation of replacement
buffer fails" rule. With XDP we extended that to the TX action,
so if XDP prog returned TX but allocation of replacement RX buffer
failed, we will drop the packet.
To improve our XDP TX performance extend the idea of rings being
always full to XDP TX rings. Pre-fill the XDP TX rings with RX
buffers, and when XDP prog returns TX action swap the RX buffer
with the next buffer from the TX ring.
XDP TX complete will no longer free the buffers but let them
sit on the TX ring and wait for swap with RX buffer, instead.

Creating a geneve link with 'udpcsum' set results in a creation of link

The message "Cannot bind port X, err=Y" creates only confusion. In metadata
based mode, failure of IPv6 socket creation is okay if IPv6 is disabled and
no error message should be printed. But when IPv6 tunnel was requested, such
failure is fatal. The vxlan_socket_create does not know when the error is
harmless and when it's not.
Instead of passing such information down to vxlan_socket_create, remove the
message completely. It's not useful. We propagate the error code up to the
user space and the port number comes from the user space. There's nothing in
the message that the process creating vxlan interface does not know.

When IPv6 is compiled but disabled at runtime, __vxlan_sock_add returns
-EAFNOSUPPORT. For metadata based tunnels, this causes failure of the whole
operation of bringing up the tunnel.
Ignore failure of IPv6 socket creation for metadata based tunnels caused by
IPv6 not being available.
