[Crash-utility] [PATCH] crash: load of module types LKCD_KERNTYPES
This patch allows additional kerntypes files to be loaded as module
debuginfo (namelist) files.
It's a bit of a kludge, as sym -s module <file> still requires
that these types be associated with a loaded module. (but its use
would only be desirable when there are loaded modules, so that
restriction should not be a problem)
Tested against a live 2.6.27 kernel.
Diffed against crash-4.0-7.6
