3b49b6cde5 ARM: dts: imx6ul-14x14-evk: Pass the "broken-cd" property
imx6ul-14x14-evk does not have a GPIO dedicated for reading the card
detect pin on the eSDHC2 micro-SD port.

Pass the "broken-cd" property to describe the absence of the card detect
GPIO so that polling must be used.

According to Documentation/devicetree/bindings/mmc/mmc-controller.yaml:

  broken-cd:
    $ref: /schemas/types.yaml#/definitions/flag
    description:
      There is no card detection available; polling must be used.

Even though no error is oberved in the kernel, the lack of the
'broken-cd' property caused the micro-SD to not be detected in U-Boot,
so let's improve the device tree description to make it more accurate.

bb3bd0740d ARM: dts: imx6sl-tolino-shine3: Remove incorrect power supply assignment
The vdd3p0 LDO's input should be from external USB VBUS directly, NOT
PMIC's power supply, the vdd3p0 LDO's target output voltage can be
controlled by SW, and it requires input voltage to be high enough, with
incorrect power supply assigned, if the power supply's voltage is lower
than the LDO target output voltage, it will return fail and skip the LDO
voltage adjustment, so remove the power supply assignment for vdd3p0 to
avoid such scenario.

99c2e3793f ARM: dts: imx6qdl-icore: Add fec phy-handle
LAN8720 needs a reset of every clock enable. The reset needs
to be done at device level, due the flag PHY_RST_AFTER_CLK_EN.

So, add phy-handle by creating mdio child node inside fec.
This will eventually move the phy-reset-gpio which is defined
in fec node.

Some pinmuxings are obviously wrong, originating from a copy/paste

- Set all reserved bits to zero
- Leave drive strength and slew rate as is
- Add sensible pull and hysteresis depending on the function of the pin
- Not used pins are muxed to their reset-value defined by the SoC

On the LS1021A-TSN board, the 2 Atheros AR8031 PHYs for eth0 and eth1

Switching to interrupts offloads the PHY library from the task of
polling the MDIO status and AN registers (1, 4, 5) every second.

Unfortunately, the BCM5464R quad PHY connected to the switch does not
appear to have an interrupt line routed to the SoC.

316933cf74 orangefs: posix open permission checking...
Orangefs has no open, and orangefs checks file permissions
 on each file access. Posix requires that file permissions
 be checked on open and nowhere else. Orangefs-through-the-kernel
 needs to seem posix compliant.
 
 The VFS opens files, even if the filesystem provides no
 method. We can see if a file was successfully opened for
 read and or for write by looking at file->f_mode.
 
 When writes are flowing from the page cache, file is no
 longer available. We can trust the VFS to have checked
 file->f_mode before writing to the page cache.
 
 The mode of a file might change between when it is opened
 and IO commences, or it might be created with an arbitrary mode.
 
 We'll make sure we don't hit EACCES during the IO stage by
 using UID 0.

Possibly most interesting is Trond's fixes for some callback races that
 were due to my incomplete understanding of rpc client shutdown.
 Unfortunately at the last minute I've started noticing a new
 intermittent failure to send callbacks.  As the logic seems basically
 correct, I'm leaving Trond's patches in for now, and hope to find a fix
 in the next week so I don't have to revert those patches.

0fc75219fe r8169: fix rtl_hw_jumbo_disable for RTL8168evl
In referenced fix we removed the RTL8168e-specific jumbo config for
RTL8168evl in rtl_hw_jumbo_enable(). We have to do the same in
rtl_hw_jumbo_disable().

v2: fix referenced commit id

85190d15f4 pipe: don't use 'pipe_wait() for basic pipe IO
pipe_wait() may be simple, but since it relies on the pipe lock, it
means that we have to do the wakeup while holding the lock.  That's
unfortunate, because the very first thing the waked entity will want to
do is to get the pipe lock for itself.

So get rid of the pipe_wait() usage by simply releasing the pipe lock,
doing the wakeup (if required) and then using wait_event_interruptible()
to wait on the right condition instead.

wait_event_interruptible() handles races on its own by comparing the
wakeup condition before and after adding itself to the wait queue, so
you can use an optimistic unlocked condition for it.

a28c8b9db8 pipe: remove 'waiting_writers' merging logic
This code is ancient, and goes back to when we only had a single page
for the pipe buffers.  The exact history is hidden in the mists of time
(ie "before git", and in fact predates the BK repository too).

At that long-ago point in time, it actually helped to try to merge big
back-and-forth pipe reads and writes, and not limit pipe reads to the
single pipe buffer in length just because that was all we had at a time.

However, since then we've expanded the pipe buffers to multiple pages,
and this logic really doesn't seem to make sense.  And a lot of it is
somewhat questionable (ie "hmm, the user asked for a non-blocking read,
but we see that there's a writer pending, so let's wait anyway to get
the extra data that the writer will have").

But more importantly, it makes the "go to sleep" logic much less
obvious, and considering the wakeup issues we've had, I want to make for
less of those kinds of things.

f467a6a664 pipe: fix and clarify pipe read wakeup logic
This is the read side version of the previous commit: it simplifies the
logic to only wake up waiting writers when necessary, and makes sure to
use a synchronous wakeup.  This time not so much for GNU make jobserver
reasons (that pipe never fills up), but simply to get the writer going
quickly again.

A bit less verbose commentary this time, if only because I assume that
the write side commentary isn't going to be ignored if you touch this
code.
