+-d option outs wrong info about sections
+
+For example, after run ./qemu-i386 -d in_asm /bin/ls from 0.14.0 release, I received this qemu.log file:
+$ cat /tmp/qemu.log | grep -A7 guest
+Relocating guest address space from 0x08048000 to 0x8048000
+guest_base  0x0
+start    end      size     prot

+
+But such command in 0.12.5 release outs this:
+$ cat /tmp/qemu.log | grep -A7 guest
+guest_base  0x0

+
+It looks correct.
+I received such differences and with qemu-microblaze. 
+
+After comparing 0.12.5 and 0.14.0 releases I found this differences in exec.c:
+in 0.12.5:
+end = (i << (32 - L1_BITS)) | (j << TARGET_PAGE_BITS);
+
+in 0.14.0:
+int rc = walk_memory_regions_1(&data, (abi_ulong)i << V_L1_SHIFT,
+
+V_L1_SHIFT in my case is 10, but 32 - L1_BITS is 22
+
+I make this changes:

+I don't know code base good, and think what may to do more general corrections.
