It applies cleanly to both branches. It fixes 171cc0d9eed1 ("genirq/proc: Speed up /proc/interrupts iteration"), which landed in v7.2-rc1, so both series are affected. The fix was merged into mainline after v7.3, so it is not in a release yet. The bug causes the CPU header to be missing from /proc/interrupts on large systems, such as the 192-CPU 8g.48xl and 384-CPU 8i.96xl AWS instance types, which breaks userspace tools that expect the header.
