Description

Forgot to shift kernel configs for rockchip family when switching current to 6.6 and edge 6.7; done right now.

Curiously I noticed this after hitting "buggy" behaviour on rk322x board with several rcu_scheduler debug messages while board was under high load, vnstatd process was often at 100% cpu usage and reading /proc/net/dev file (which is a simple text file with some network interface stats) stalls vnstatd. Turning off eth0 interface solved the problem but of course it was not solution.

I shifted the kernel config, recompiled kernel 6.6 and this apparently solved the problem (maybe thanks to CONFIG_NEED_SRCU_NMI_SAFE=y ?)

If it is so, the consideration I make here is that using that using a kernel config that does not match the kernel version may, in some corner cases, be harmful for stability

How Has This Been Tested?

• [x] Kernel deb packages compiled and tested on live rk322x system
