This series aims to clean up an aspect of coredump generation:
ELF coredumps contain a set of notes describing the state of machine

Notes are identified by a numeric identifier n_type and a "name"

There is a generic ARCH_HAS_CACHE_LINE_SIZE option introduced by
commit c2280be81de4 ("mm: generalize ARCH_HAS_CACHE_LINE_SIZE")
in mm/Kconfig. Select that instead.

They are only used within mmu.c. Make them static.

Remove the declaration of 'err' inside the 'if (timetravel)' block,
as it would otherwise be unavailable outside that block, potentially
leading to uml_rtc_start() returning an uninitialized value.

It can be used when we want to pass through PCI devices to UML
while it's up and running. PCI devices can be passed through to
UML using the same syntax as the command line option:
(mconsole) config vfio_uml.device=
