[PATCH 0/8] Add GDB memory helper commands

[Kuan-Ying Lee]

Hi all,

I've created some GDB commands I think useful when I debug
some memory issues and kernel module issue.

For memory issue, we would like to get slabinfo, slabtrace,
page_owner and vmallocinfo to debug the memory issues.

For module issue, we would like to query kernel module name
when we get a module text address and load module
symbol by specific path.

This patchset is based on v6.5-rc3.

Patch 1-2:
 - Add kernel module releated command.
Patch 3-5:
 - Prepares for the memory-releated command.
Patch 6-8:
 - Add memory-related commands.
