emit_ld is wrong, because thread_info.cpu is 32-bit, not xlen-bit wide. The struct currently has a hole after cpu, so little endian accesses seemed fine. Fixes: 19c56d4 ("riscv, bpf: add internal-only MOV instruction to resolve per-CPU addrs") Cc: <stable@vger.kernel.org> Signed-off-by: Radim Krčmář <rkrcmar@ventanamicro.com> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
