Hengqi Chen f296248daf LoongArch, bpf: Use 4 instructions for function address in JIT ... [ Upstream commit 64f50f6575 ] This patch fixes the following issue of function calls in JIT, like: [ 29.346981] multi-func JIT bug 105 != 103 The issus can be reproduced by running the "inline simple bpf_loop call" verifier test. This is because we are emiting 2-4 instructions for 64-bit immediate moves. During the first pass of JIT, the placeholder address is zero, emiting two instructions for it. In the extra pass, the function address is in XKVRANGE, emiting four instructions for it. This change the instruction index in JIT context. Let's always use 4 instructions for function address in JIT. So that the instruction sequences don't change between the first pass and the extra pass for function calls.
