Hello,
This small patch series intends to add support for the PMU of the
Cortex-A72 cores found in the Marvell Armada 7K/8K SoCs.
However, the interrupt of the PMU is not directly connected to the
GIC, but goes through a secondary interrupt controller called the
PIC. Therefore, this series
The Marvell Armada 7K/8K integrates a secondary interrupt controller
very originally named "PIC". It is connected to the main GIC via a
PPI. Amongst other things, this PIC is used for the ARM PMU.
This commit adds a simple irqchip driver for this interrupt
controller. Since this interrupt

Hi Ted, Herbert,
I sent a question to the ATH9K RNG some time ago to the developers.
See https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg19115.html
I have not yet received a word and I think this issue should be resolved.
Thanks

In current code, decay_load() will consider to set load value to zero
after passing 32*64 ms. So this means max_load * (0.5^64) ~= 0.
Kernel can support maximum number of processes and threads to 2^29 and
set task with highest priority with nice=-20 (weight = 88761). So in

There is currently no non-fbdev mechanism in place to kick out
simpledrm when the real hw-driver is probed. As a stop gap until
that is in place, honour remove_conflicting_framebuffers() and
delete the simple-framebuffer platform device when it's called.

This patchset adds the simpledrm driver by David Herrmann based on a
patchset[1] from 2014. That patchset also included patches for kicking
out simpledrm by real drivers. I have stayed away from that since it
involves another subsystem and I would probably be unable to answer any
questions about

The SimpleDRM driver binds to simple-framebuffer devices and provides a

plus one initial mode.
Userspace can create dumb-buffers which can be blit into the real

Hi Linus,
Please pull these arm64 fixes for -rc1. The branch is based on the
for-next/core tag you pulled from Catalin last week. He's on holiday
once again, so I'm handling the fixes until he's back.

they don't shouldn't need to flush a TLB. But then there is iounmap()

Is it possible to write a kernel module which, when loaded, will blow

Hello,
There have been several discussions around CPU controller support.
Unfortunately, no consensus was reached and cgroup v2 is sorely
lacking CPU controller support. This document includes summary of the
situation and arguments along with an interim solution for parties who

While the cpu controller doesn't have any functional problems, there
are a couple interface issues which can be addressed in the v2
interface.

Hi guys
I noticed following errors with current tree.
Bisected to nowhere :(
Anyone has an idea ?

Hi Eric,
I have tested these patches in a VFIO PCI scenario (using the ITS
emulation) on a NXP LS2080 board. It worked fine with one e1000 card
assigned to the guest. However, when I tried to assign two cards to the
guest I got a crash. I narrowed down the problem to this code:

Make the following changes in preparation for the cpu controller
interface implementation for the unified hierarchy. This patch
doesn't cause any functional differences.

Long time ago there was a similar fix proposed by Akinobu Mita[1],
but it seems that time everyone decided to fix this subtle race in
percpu-refcount and Tejun Heo[2] did an attempt (as I can see that
patchset was not applied).
The following is a description of a queue hang - same fix but a bug
percpu issues some RCU callbacks to synchronize its state, so before
freeing we have to wait all those callbacks to finish.
E.g. the following simple sequence on stack causes nasty crash:
struct percpu_ref ref;
percpu_ref_init(, release, 0, GFP_KERNEL);
percpu_ref_kill();

my preference would be to remove Lindent instead.

Do you have any examples of hardware that might use this on both the
controller and device
The VMXNet3 PCI Id will be shared with our upcoming paravirtual RDMA
driver. Moved it to the shared location in pci_ids.h and updated the

Oops, right. :)
I'll fix that.
