Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=936c8be4d1447f36ac4d2a464bd03a5cd659c42f

--------------------------------

commit 95c5436a upstream.

Move the call of dump_vma_snapshot and kvfree(vma_meta) out of the
individual coredump routines into do_coredump itself.  This makes
the code less error prone and easier to maintain.

Make the vma snapshot available to the coredump routines
in struct coredump_params.  This makes it easier to
change and update what is captures in the vma snapshot
and will be needed for fixing fill_file_notes.
