[PATCH v3 12/26] kernel/vmcore_info: Register dynamic information into meminspect

From: Eugen Hristev <[email protected]>

Register vmcoreinfo information into the inspection table.
Because the size of the info is computed after all entries are
added, there is no point in registering the whole page; instead,
call the inspection registration once everything is in place with
the right size. A second reason is that the vmcoreinfo is added
as a region inside the ELF core image note, so there is no point
in having blank space at the end.
