The recent commit to rework the hash MMU setup broke the build when
CONFIG_PPC_NATIVE=n. Fix it by providing a fallback implementation of
hpte_init_native().
Fixes: 166dd7d3fbf2 ("powerpc/64: Move MMU backend selection out of platform
code")

hpte_init_lpar() is part of the pseries platform, so name it as such.
Provide the fallback implementation in a header, rather than using a
weak function.

These files were only including module.h for exception table
related functions. We've now separated that content out into its
own file "extable.h" so now move over to that and avoid all the
extra header content in module.h that we don't really need to compile
these files.

As long as nobody thinks the general idea is horrible, I'll expand into
more fringe arch and resend in 2wks and get it added then to linux-next.]
While doing an audit looking for unnecessary instances of module.h
inclusion acr
tabort_syscall runs with RI=1, so a nested recoverable machine
check will load the paca into r13 and overwrite what we loaded
it with, because exceptions returning to privileged mode do not
restore r13.

Currently the cxl driver attempts to bind to any class 1200 (processing
accelerator) device, and only works out whether it's actually a CAPI card
later on. This doesn't really break anything (if it's not a CAPI card,
we'll abort very quickly), but ideally we'd like to remove this and be
explicit ab
