+Subject: [PATCH] [GDBserver] Fix conversion warning
+
+I got the following warning if I build GDBserver for aarch64_be-linux-gnu,
+
+git/gdb/gdbserver/linux-aarch64-low.c:1539:39: error: invalid conversion from 'void*' to 'uint32_t* {aka unsigned int*}' [-fpermissive]
+   uint32_t *le_buf = xmalloc (byte_len);
+                                       ^
+The patch is to fix the warning.
