To implement per-object slab memory accounting, we need to convert slab

per-node, per-memcg and per-lruvec only two last levels will require
byte-sized counters. It's because global and per-node counters will be

Instead of having two sets of kmem_caches: one for system-wide and

The idea is simple: space for obj_cgroup metadata can be allocated on

Shenzhen Yangliming Electronic Technology Co., Ltd., abbreviated YLM or
YLMChina, and known as Anbernic in the rest of the world, is a Chinese
manufacturer of handheld game consoles, some of which are known to be
running Linux.

The RS-90, better known as RetroMini, is a small and pocketable handheld
gaming console from YLMChina. It has little more than a JZ4725B SoC, a
NAND, a screen, some buttons and a speaker.

Add preliminary support for boards based on the JZ4725B SoC from
Ingenic.
The JZ4725B SoC is supposed to be older than the JZ4740 SoC, but its
internals are much closer to what can be found on the JZ4750 and newer
SoCs.
It is low-power SoC with a MIPS32r1 SoC running at ~360 MHz, and no FPU.

Use an enum instead of macros to represent the various versions of the
Ingenic SoCs, and add some of the SoC versions that were previously
missing.

By default intel_pstate driver disables energy efficiency by setting
MSR_IA32_POWER_CTL bit 19 for Kaby Lake desktop CPU model in HWP mode.
This CPU model is also shared by Coffee Lake desktop CPUs. This allows
these systems to reach maximum possible frequency. But this adds power
penalty, which so

The struct does not contain 64-bit types, and therefore
doesn't suffer from compatibility issues.
However, having it aligned to 64-bits is cleaner and
has the advantage of allowing future extensions.

Slice header syntax element 'first_mb_in_slice' can point

65536 macroblocks which is insufficient for 8K videos.
DPB entry PicNum maximum value is 2*MaxFrameNum for interlaced

When dealing with with interlaced frames, reference lists must tell if
each particular reference is meant for top or bottom field. This info
is currently not provided at all in the H264 related controls.

The recent patch posted by Jernej (which I'm including for context),
encouraged me to address all the known issues in the uAPI.
I hope we can finally make this uAPI interface

interfaces so we can move the codec drivers out of staging.
