+qemu-user: zero_bss might raise segfault when segment is not writable
+Description of problem:
+When a PT_LOAD segment with the following attributes presented in the user program,
+* MemSiz > FileSiz
+* NOT Writable
+
+qemu-aarch64 will crash with segment fault running it.
+
+
+
+
+in [linux-user/elfload.c: bss_zero](https://gitlab.com/qemu-project/qemu/-/blob/master/linux-user/elfload.c#L2097), the exceeded part is zero'ed without checking if it is writable
+```
+    if (host_start < host_map_start) {
+        memset((void *)host_start, 0, host_map_start - host_start);
+    }
+```
+Steps to reproduce:
+1. ./qemu-aarch64 ./X.so
+Additional information:
