kallsyms_symbol_next() returns a boolean (true on success). Currently
kdb_read() tests the return value with an inequality that
unconditionally evaluates to true.
This is fixed in the obvious way and, since the conditional branch is
supposed to be unreachable, we also add a WARN_ON().

mdesc_kmalloc is currently requiring __GFP_NOFAIL allocation although it

Use assigned-clocks/assigned-clock-parents properties for
CMU clock controller DT node to secure proper clock setup:
switching the two muxes to root oscillator clock is not only
required for proper powering down the ISP power domain,
but it also reduces the risk of accessing the ISP CMU
registers w

This phrase could use rewording I think.

git://git.kernel.org/pu
This patch implements the static part of the s390 cpu class definitions.
It defines s390 cpu models by means of virtual cpu ids (enum) which contain
information on the cpu generation, the machine class, the GA number and
the machine type. The cpu id is used to instantiate a cpu class per cpu
model.
This patch introduces the helper "gen-facilities" which allows to generate
facility list definitions and masks at compile time. Its flexibility is
better and the error-proneness is lower when compared to static programming
time added statements.
The helper includes "target-s390x/cpu-facilities.h"
QEMU now switches into "probe mode" when the selected machine is "none" and no
specific accelerator(s) has been requested (i.e.: "-machine none").
In probe mode a by "_CONFIG" defines predefined list of accelerators run
their init() methods.
