Hi Bruce,
I just finished insane check to build xilinx-zynqmp machine with
core-image-sato, all passed with boot process.
Could you please help me to create a branch like that
standard/xilinx-zynqmp in the following git repo. in convenient
/standard/base, thanks~

When I created the structure I had intended for it to include the

Hi Bruce,
Here are the v2 changes for scc/cfg:
*) Create the minimum cfg set for arm/arm64, and include it
*) Remove those CFG only existed in Xilinx SDK.
*) Include hotplug scc
*) Remove some non-validation features, like remoteproc
This patch is to add scc/cfg meta to build and boot zcu102 board with the bsp
of xilinx-zynqmp.

No kernel build warnings. And the boot process is still OK.

This patch is to create the minimum set for cpu idle/freq scaling, which is ok
to both arm and arm64 with DT enablement. And we leave more specific features

Hi Bruce,
Forget this party :)
xilinx-zynqmp is arm64 BSP with cortexA53, and it seems stable in mainline
to build and boot, so I add it into linux-yocto-dev and yocto-kernel-cache.

We used to have the CPU online failure path where a worker is created

the CPU coming online and if the online operation failed the created worker

Hi Bruce,
As we discussed before, these patch series intended to fix a potential
kernel crash, which is due to a invalid mm context from worker_create,
and it is introduced by efb5fea2, which is a continuation of efforts
trying to optimize find_vma(), avoiding potentially expensive rbtree

I think you might mis-understand Bruce for his comments,
in most situation, you had better go through your patch again
