[PATCH v4 0/6] allow ramoops to collect all kmesg_dump events

[Kees Cook]

Hello!

I wanted to get the pstore tree nailed down, so here's the v4 of
Pavel's series, tweaked for the feedback during v3 review.

-Kees

v4:
- rebase on pstore tree
- collapse shutdown types into a single dump reason
  https://lore.kernel.org/lkml/CA+CK2bAPv5u1ih5y9t5FUnTyximtFCtDYXJCpuyjOyHNOkRdqw@mail.gmail.com/
- fix dump_oops vs max_reason module params
  https://lore.kernel.org/lkml/20200512233504.GA118720@sequoia/
- typos

- rename DT parsing routines ..._size -> ..._u32
