+Subject: arm64/uprobes: change the uprobe_opcode_t typedef to fix the sparse warning
+
+From: junhua huang <huang.junhua@zte.com.cn>
+
+commit ef08c0fadd8a17ebe429b85e23952dac3263ad34 upstream.
+
+After we fixed the uprobe inst endian in aarch_be, the sparse check report
+the following warning info:

+
+use the __le32 to u32 for uprobe_opcode_t, to keep the same.
