CVE-2023-53030

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-pf: Avoid use of GFP_KERNEL in atomic context

Using GFPKERNEL in preemption disable context, causing below warning when CONFIGDEBUGATOMICSLEEP is enabled.

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