      ptrace: Properly initialize ptracer_cred on fork · c70d9d80
      由 Eric W. Biederman 提交于 
      When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default.  This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.

Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.

Fix this by properly initializing ptracer_cred in ptrace_init_task

This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork.  Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

      arm64: dts: hikey: Fix WiFi support · ea452678
      由 Ulf Hansson 提交于 
      The description of the connection between the dwmmc (SDIO) controller and
the Wifi chip, which is attached to the SDIO bus is wrong. Currently the
SDIO card can't be detected and thus the Wifi doesn't work.

Let's fix this by assigning the correct vmmc supply, which is the always on
regulator VDD_3V3 and remove the WLAN enable regulator altogether. Then to
properly deal with the power on/off sequence, add a mmc-pwrseq node to
describe the resources needed to detect the SDIO card.

Except for the WLAN enable GPIO and its corresponding assert/de-assert
delays, the mmc-pwrseq node also contains a handle to a clock provided by
the hi655x pmic. This clock is also needed to be able to turn on the WiFi
chip.

While changing this, let's take the opportunity to drop the use of the
"ti,non-removable" binding for one of the dwmmc device nodes, as it's not a
valid binding and not used. Drop also the unnecessary use of "num-slots =
<0x1>" for all of the dwmmc nodes, as there is no need to set this since
when default number of slots is one.

      During power off, after the GPIO pin has been asserted, some devices like
the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
clock gating and turning off regulators as to follow a graceful shutdown
sequence.

Therefore invent an optional power-off-delay-us DT binding for
mmc-pwrseq-simple, to allow us to support this constraint.

      I failed to properly onion-wrap the unwind code: We acquire the vblank

unwrapping code that doesn't use separate labels for each stage, but
checks each pointer first ... While re-reading everything I also
realized that we must clean up the fb refcounts, and specifically
plane->old_fb before we drop the locks, either in the final unlocking,
or in the w/w retry path. Hence the correct fix is to drop the
vblank_put to the very bottom.

      drm: qxl: Delay entering atomic context during cursor update · 429030bc
      由 Gabriel Krisman Bertazi 提交于 
      qxl_release_map will enter an atomic context, but since we still need to
alloc memory for BOs, we better delay that until we have everything we
need, in case we need to sleep inside the allocation.  This avoids the
Sleep in atomic state below, which was reported by Mike.
