Puranjay Mohan be708ed300 bpf/arm64: Fix BPF_ST into arena memory ... The arm64 JIT supports BPF_ST with BPF_PROBE_MEM32 (arena) by using the tmp2 register to hold the dst + arena_vm_base value and using tmp2 as the new dst register. But this is broken because in case is_lsi_offset() returns false the tmp2 will be clobbered by emit_a64_mov_i(1, tmp2, off, ctx); and hence the emitted store instruction will be of the form: strb w10, [x11, x11] Fix this by using the third temporary register to hold the dst + arena_vm_base. Fixes: 339af577ec ("bpf: Add arm64 JIT support for PROBE_MEM32 pseudo instructions.")
