[PATCH 6.7 030/713] bpf: Fix warning for bpf_cpumask in verifier

From: Sasha Levin
Date: Mon Mar 25 2024 - 03:32:06 EST


From: Hari Bathini <hbathini@xxxxxxxxxxxxx>

[ Upstream commit 11f522256e9043b0fcd2f994278645d3e201d20c ]

Compiling with CONFIG_BPF_SYSCALL & !CONFIG_BPF_JIT throws the below
warning:

"WARN: resolve_btfids: unresolved symbol bpf_cpumask"

Fix it by adding the appropriate #ifdef.
