[Qemu-devel] [PATCH] translate-all: Fix formatting of dump output

[Stefan Weil <sw@weilnetz.de>]

The page dump writes a table with 3 abi_ulong values in each row.
These values take 8 or 16 characters (depending on sizeof abi_ulong).

Fix the table headings to be aligned with the table columns.

old:
start    end      size     prot
0000000120000000-000000012021e000 000000000021e000 rwx
0000004000000000-0000004000002000 0000000000002000 ---
0000004000002000-0000004000802000 0000000000800000 rw-
