Building loongarch:defconfig ... failed
--------------
Error log:
In file included from arch/loongarch/net/bpf_jit.c:7:
arch/loongarch/net/bpf_jit.h: In function 'emit_nop':
arch/loongarch/net/bpf_jit.h:30:22: error: 'INSN_NOP' undeclared

Caused by commit e9ccb262b39a ("LoongArch: BPF: Fix off-by-one error
in build_prologue()"). INSN_NOP was introduced with commit 19e5eb15b00c5
in v6.2.

Also, the description of e9ccb262b39a says "With BPF progs mixing bpf2bpf
and tailcalls...". Support for that was introduced in v6.4 with commit
bb035ef0cc91 ("LoongArch: BPF: Support mixing bpf2bpf and tailcalls"),
so I do wonder if e9ccb262b39a was really needed in 6.1.
