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.
