HEAD: 390031c942116d4733310f0684beb8db19885fe6 coredump: Use the vma snapshot in fill_files_note
Matthew Wilcox has reported that a missing mmap_lock in file_files_note,
which could cause trouble.
Refactor the code and clean it up so that the vma snapshot makes
it to fill_files_note, and then use the vma snapshot in fill_files_note.

coredump: Move definition of struct coredump_params into coredump.h
coredump: Snapshot the vmas in do_coredump
coredump: Remove the WARN_ON in dump_vma_snapshot
coredump/elf: Pass coredump_params into fill_note_info
coredump: Use the vma snapshot in fill_files_note

Kees I realized I needed to rebase this on Jann Horn's commit
84158b7f6a06 ("coredump: Also dump first pages of non-executable ELF
libraries"). Unfortunately before I got that done I got distracted and
these changes have been sitting in limbo for most of the development
cycle. Since you are running a tree that is including changes like this
including Jann's can you please pull these changes into your tree.
Thank you,
Eric
