[Crash-utility] [PATCH] Fix the issue of "page excluded" messages flooding
The current issue is only observed on PPC64le machine when loading crash,
E.g:
...
crash: page excluded: kernel virtual address: c0000000022d6098 type:
"gdb_readmem_callback"
crash: page excluded: kernel virtual address: c0000000022d6098 type:
"gdb_readmem_callback"
...
crash>
And this issue can not be reproduced on crash 8, which only occurred
after the gdb-16.2 upgrade(see commit dfb2bb55e530).
So far I haven't found out why it always reads the same address(excluded
page) many times, anyway, crash tool should avoid flooding messages firstly,
similarly let's use the same debug level(8) such as the read_diskdump()(see
diskdump.c).
