Revert "ext4: allow readdir()'s of large empty directories to be interrupted"
This reverts commit
1028b55bafb7611dda1d8fed2aeca16a436b7dff.
It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.
You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.
I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.
So my track record is not good enough, and the stars will have to align
better before that one gets committed. And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.
IOW, let's just revert the commit that caused the problem for now.

Core fixes:
- Defer GPIO device setup until after gpiolib is initialized.
It turns out that a few very tightly integrated GPIO platform
drivers initialize so early (befor core_initcall()) so that the
gpiolib isn't even initialized itself. That limits what the
library can do, and we cannot reference uninitialized fields until
later.
Defer some of the initialization until right after the gpiolib is
initialized in these (rare) cases.
- As a consequence: do not use devm_* resources when allocating the
states in the initial set-up of the gpiochip.
Driver fixes:
- In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.
- Fix legacy builds on the PXA without a backing pin controller.

mpls: find_outdev: check for err ptr in addition to NULL check
find_outdev calls inet{,6}_fib_lookup_dev() or dev_get_by_index() to
find the output device. In case of an error, inet{,6}_fib_lookup_dev()
returns error pointer and dev_get_by_index() returns NULL. But the function
only checks for NULL and thus can end up calling dev_put on an ERR_PTR.
This patch adds an additional check for err ptr after the NULL check.

gpio: pxa: fix legacy non pinctrl aware builds
In legacy pxa builds, ie. non device-tree and platform-data only builds,
pinctrl is not yet available. As a consequence, the pinctrl gpio
direction change function is a stub, returning always success.
In the current state, the gpio driver direction function believes the
pinctrl direction change was successful, and exits without actually
changing the gpio direction.
This patch changes the logic :
- if the pinctrl direction function fails, gpio direction will report
that failure
- if the pinctrl direction function succeeds, gpio direction is changed
by the gpio driver anyway.
This is sub optimal in the pinctrl aware case, as the gpio direction
will be changed twice: once by pinctrl function and another time by
the gpio direction function.
Yet it should be acceptable in this form, as this is functional for all
pxa platforms (device-tree and platform-data), and moreover changing a
gpio direction is very very seldom, usually in machine initialization,
seldom in drivers probe, and an exception for ac97 reset bug.

gpio / ACPI: ignore GpioInt() GPIOs when requesting GPIO_OUT_*
When firmware does not use _DSD properties that allow properly name GPIO
resources, the kernel falls back on parsing _CRS resources, and will
return entries described as GpioInt() as general purpose GPIOs even
though they are meant to be used simply as interrupt sources for the
device:
Device (ETSA)
{
Name (_HID, "ELAN0001")
...
Method(_CRS, 0x0, NotSerialized)
{
Name(BUF0,ResourceTemplate ()
{
I2CSerialBus(
0x10, /* SlaveAddress */
ControllerInitiated, /* SlaveMode */
400000, /* ConnectionSpeed */
AddressingMode7Bit, /* AddressingMode */
"\\_SB.I2C1", /* ResourceSource */
)
GpioInt (Edge, ActiveLow, ExclusiveAndWake, PullNone,,
"\\_SB.GPSW") { BOARD_TOUCH_GPIO_INDEX }
} )
Return (BUF0)
}
...
}
This gives troubles with drivers such as Elan Touchscreen driver
(elants_i2c) that uses devm_gpiod_get to look up "reset" GPIO line and
decide whether the driver is responsible for powering up and resetting
the device, or firmware is. In the above case the lookup succeeds, we
map GPIO as output and later fail to request client->irq interrupt that
is mapped to the same GPIO.
Let's ignore resources described as GpioInt() while parsing _CRS when
requesting output GPIOs (but allow them when requesting GPIOD_ASIS or
GPIOD_IN as some drivers, such as i2c-hid, do request GPIO as input and
then map it to interrupt with gpiod_to_irq).

It's easiest if we just pass in an adjusted resource range rather than

Aside from the crash, the shortcomings of that patch are as follows:
- It makes the ib_srpt driver use I/O contexts allocated by
transport_alloc_session_tags() but it does not initialize these I/O
contexts properly. All the initializations performed by
srpt_alloc_ioctx() are skipped.
- It swaps the order of the send ioctx allocation and the transition to
RTR mode which is wrong.
- The amount of memory that is needed for I/O contexts is doubled.
- srpt_rdma_ch.free_list is no longer used but is not removed.

"These changes contains a fix for overlayfs interacting with some
(badly behaved) dentry code in various file systems. These have been
reviewed by Al and the respective file system mtinainers and are going
through the ext4 tree for convenience.
This also has a few ext4 encryption bug fixes that were discovered in
Android testing (yes, we will need to get these sync'ed up with the
fs/crypto code; I'll take care of that). It also has some bug fixes
and a change to ignore the legacy quota options to allow for xfstests
regression testing of ext4's internal quota feature and to be more
consistent with how xfs handles this case"

ARM: 8550/1: protect idiv patching against undefined gcc behavior
It was reported that a kernel with CONFIG_ARM_PATCH_IDIV=y stopped
booting when compiled with the upcoming gcc 6. Turns out that turning
a function address into a writable array is undefined and gcc 6 decided
it was OK to omit the store to the first word of the function while
still preserving the store to the second word.
Even though gcc 6 is now fixed to behave more coherently, it is a
mystery that gcc 4 and gcc 5 actually produce wanted code in the kernel.
And in fact the reduced test case to illustrate the issue does indeed
break with gcc < 6 as well.
In any case, let's guard the kernel against undefined compiler behavior
by hiding the nature of the array location as suggested by gcc
developers.
