Revert "ARM: dts: rockchip: add startup delay to rk3288-veyron panel-regulators"

This reverts commit 1f45e8c6d0161f044d679f242fe7514e2625af4a.

This 100 ms mystery delay is not on downstream kernels and no longer
seems needed on upstream kernels either [1].  Presumably something in the
meantime has made things better.  A few possibilities for patches that
have landed in the meantime that could have made this better are
commit 3157694d8c7f ("pwm-backlight: Add support for PWM delays
proprieties."), commit 5fb5caee92ba ("pwm-backlight: Enable/disable
the PWM before/after LCD enable toggle."), and commit 6d5922dd0d60
("ARM: dts: rockchip: set PWM delay backlight settings for Veyron")

Let's revert and get our 100 ms back.

ARM: dts: Update the NSPIRE DTS files for DRM

The DRM subsystem graphics drivers require more granular
definition of the connection between display drivers and
panels, and a proper panel compatible. This utilizes the
bindings merged to the DRM subsystem to properly define
the display on the NSPIRE devices.

We also do away with the undocumented DT binding
"lcd-type".

We add both the clocks to the CLCD block so the driver
have full control over its clocking.

  order to fix a long-standing race condition with the creation of sysfs
  files for USB devices. Turns out that there are now userspace tools
  out there that are hitting this long-known bug, so it's time to fix
  them. Thankfully the tool-maker in this case fixed the issue :)

  The other patches in here are all fixes for reported issues. Now that
  syzbot knows how to fuzz USB drivers better, and is starting to now
  fuzz the userspace facing side of them at the same time, there will be
  more and more small fixes like these coming, which is a good thing.

4 years agokbuild: show hint if subdir-y/m is used to visit module Makefile
Masahiro Yamada [Thu, 8 Aug 2019 11:21:11 +0000 (20:21 +0900)]
kbuild: show hint if subdir-y/m is used to visit module Makefile

Since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead
of $(MODVERDIR)/*.mod"), a module is no longer built in the following
pattern:

  [Makefile]
  subdir-y := some-module

  [some-module/Makefile]
  obj-m := some-module.o

You cannot write Makefile this way in upstream because modules.order is
not correctly generated. subdir-y is used to descend to a sub-directory
that builds tools, device trees, etc.

For external modules, the modules order does not matter. So, the
Makefile above was known to work.

I believe the Makefile should be re-written as follows:

  [Makefile]
  obj-m := some-module/

  [some-module/Makefile]
  obj-m := some-module.o

However, people will have no idea if their Makefile suddenly stops
working. In fact, I received questions from multiple people.

Show a warning for a while if obj-m is specified in a Makefile visited
by subdir-y or subdir-m.

I touched the %/ rule to avoid false-positive warnings for the single
target.

gfs2: gfs2_walk_metadata fix

It turns out that the current version of gfs2_metadata_walker suffers
from multiple problems that can cause gfs2_hole_size to report an
incorrect size.  This will confuse fiemap as well as lseek with the
SEEK_DATA flag.

Fix that by changing gfs2_hole_walker to compute the metapath to the
first data block after the hole (if any), and compute the hole size
based on that.

Fixes xfstest generic/490.

s390 does not map the vdso for statically linked binaries, assuming

However with glibc commit d665367f596d ("linux: Enable vDSO for static

binaries - if the kernel would make it available.

Therefore map the vdso always, just like all other architectures.

KVM: arm/arm64: vgic: Reevaluate level sensitive interrupts on enable

A HW mapped level sensitive interrupt asserted by a device will not be put
into the ap_list if it is disabled at the VGIC level. When it is enabled

We could argue that this can also happen on real hardware, when the command
to enable the interrupt reached the GIC before the device had the chance to
de-assert the interrupt signal; however, we emulate the distributor and
redistributors in software and we can do better than that.
