This series aims to clean up an aspect of coredump generation:

ELF coredumps contain a set of notes describing the state of machine
registers and other information about the dumped process.

Notes are identified by a numeric identifier n_type and a "name"
string, although this terminology is somewhat misleading.  Officially,
the "name" of a note is really an "originator" or namespace identifier
that indicates how to interpret n_type [1], although in practice it is
often used more loosely.

Thanks!

Assuming nobody screams about things going wrong in next, I'll plan to
water down the paranoid check in binfmt_elf.c:fill_thread_core_info().

Anyone copy-pasting a new arch after this is in mainline shouldn't fall
foul of this.
