compressed data will be usually loaded into last pages of
the extent (the last page for 4k) for in-place decompression
(more specifically, in-place IO), as ilustration below,
start of compressed logical extent
| end of this logical extent
|
This patch introduces an temporary _on-stack_ page
pool to reuse the freed page directly as much as
it can for better performance and release all pages
at a time, it also slightly reduces the possibility of
the potential memory allocation failure.

Prevent bus timeouts and resets on Family 16h Model 30h by not probing
reserved Ports 3 and 4.
According to the AMD BIOS and Kernel Developer's Guides (BKDG), Port 3
and Port 4 are reserved on the following devices:
- Family 15h Model 60h-6Fh
- Family 15h Model 70h-7Fh
- Family 16h Model
Enable the i2c-piix4 SMBus controller driver to enumerate I2C slave
devices using ACPI. It builds on the related I2C mux device work
in commit 8eb5c87a92c0 ("i2c: add ACPI support for I2C mux ports")
In the i2c-piix4 driver the adapters are enumerated as:
Main SMBus adapter Port 0, Port 2, ...,
This patch adds decompression backend to EROFS, which
supports uncompressed and LZ4 compressed data.
For compressed data, it uses the following strategy:
1) If outputsize is very small (totally less than a threshold),
decompress to the per-CPU buffer and do memcpy directly

commit 6befa3fde65f ("i2c: piix4: Support alternative port selection

These patches fix a couple of issues with the i2c-piix4 driver on

Reference counters are preferred to use refcount_t instead of
atomic_t.
This is because the implementation of refcount_t can prevent
overflows and detect possible use-after-free.
First convert the refcount field to refcount_t in mlx5/driver.h.
Then convert the uses to refcount_() APIs.

commit 3d1df96ad468 ("drm/imx: merge imx-drm-core and ipuv3-crtc in one module")
imx-ipuv3-crtc.o is built via imxdrm-objs. So there's no need to keep an
extra entry with a non existing config value (CONFIG_DRM_IMX_IPUV3).

refcount_t is better for reference counters since its
implementation can prevent overflows.
So convert atomic_t ref counters to refcount_t.
Also convert refcount from 0-based to 1-based.
This patch depends on PATCH 1/2.

The driver does not explicitly call atomic_set to initialize
refcount to 0.
Add the call so that it will be more straight forward to
convert refcount from atomic_t to refcount_t.

Hi, Adrian,
Firstly, really appreciate for your valuable suggestions.
For your question that " Tuning will be executed whenever the system resumes,
which is not an error. Can you explain when error recovery is needed,
and how this patch works."
We have blow questions need your help.

scale_irq_capacity() call in schedutil_cpu_util() does
util *= (max - irq)
util /= max
But the comment says
util *= (1 - irq)
util /= max
Fix the comment to match what the scaling function does.

Since the ACPI SCI is set up for system wakeup before the "noirq"
suspend of devices, it is better to make suspend-to-idle follow
suspend-to-RAM (S3) and switch over the EC to polling during "noirq"
suspend (and back to interrupt-based flow during "noirq" resume).
