From a21ab7737a503f49b04e501dbb2b15e4b336c1bc Mon Sep 17 00:00:00 2001

Subject: [PATCH 07/64] bpf: Remove the obsolte u64_stats_fetch_*_irq() users.
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.1/older/patches-6.1.82-rt27.tar.xz
Now that the 32bit UP oddity is gone and 32bit uses always a sequence
count, there is no need for the fetch_irq() variants anymore.
Convert to the regular interface.
