Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Avoid use of GFP_KERNEL in atomic context
Using GFP_KERNEL in preemption disable context, causing below warning when CONFIG_DEBUG_ATOMIC_SLEEP is enabled.

To avoid use of GFP_ATOMIC for memory allocation, disable preemption after all memory allocation is done.
