skrll | Fix types in pmap_page_clear_attributes so that the top bits of
the u_long mdpg_attrs aren't dropped giving atomic_cas_ulong no
chance of completing if any of the top bits is set.
Update pmap_page_set_attributes for consistency.
An ATF test run completed for me with this fix.

skrll | MI PMAP hardware page table walker support.
This is based on code given to me by Matt Thomas a long time ago with
many updates and bugs fixes from me.

rin | Introduce PMAP_PV_TRACK_ONLY_STUBS option, by which only empty stubs for
global functions in pmap_pvt.h are provided, instead of real support for
PV tracking.
Necessary for powerpc: Only one sub-arch (oea) has PV tracking support.
Others (booke/ibm4xx) do not at the moment (probably never for ibm4xx),
but __HAVE_PMAP_PV_TRACK is necessary, so that modules can be shared by
all of sub-archs.

skrll | Support pmap_growkernel and KASAN shadow mapping of the new KVA.
Neither mips nor ppc booke actually use pmap_growkernel (at present).
Thanks to rin@ for testing a similar patch on ppc booke.

move pmap segtab history into a new history of only 1000 entries,
but will overflow much slower than the main pmap history.
move various debug info into kernhist. make pte array checker
into an array and use it in pmap_segtab_release() and
pmap_pte_reserve(). move check before MD callback(), incase it
wants to change ptes for some reason (they're passed in, but
this callback is currently always NULL.)
clean up some history logs to reduce the number of lines required.

skrll | Provide a pmap_segtab_deactivate for symmetry with pmap_segtab_activate
and use it in pmap_deactivate
Call pmap_md_xtab_{,de}activate from pmap_segtab_{,de}activate to be used
for PMAP_HWPAGEWALKER and any caches ops that might be required.
Provide empty (for now) pmap_md_xtab_{,de}activate functions on the
platforms that use sys/uvm/pmap

rin | Fix build for ports using uvm/pmap; pmap_remove_all() returns a boolean.

thorpej | With DEBUG defined, it's possible to execute a TLB-vs-segmap consistency
check from a (soft) interrupt handler. But if a platform does not otherwise
require the pmap_tlb_miss_lock, then where will be a brief window of
inconsistency that, while harmless, will still fire an assertion in the
consistency check.
Fix this with the following changes:
1- Refactor the pmap_tlb_miss_lock into MI code and rename it from
pmap_tlb_miss_lock_{enter,exit}() to pmap_tlb_miss_lock_{enter,exit}().
MD code can still define the "md" hooks as necessary, and if so, will
override the common implementation.
2- Provde a pmap_bootstrap_common() function to perform common pmap bootstrap
operations, namely initializing the pmap_tlb_miss_lock if it's needed.
If MD code overrides the implementation, it's responsible for initializing
its own lock.
3- Call pmap_bootstrap_common() from the mips, powerpc booke, and riscv
pmap_bootstrap() routines. (This required adding one for riscv.)
4- Switch powerpc booke to the common pmap_tlb_miss_lock.
5- Enable pmap_tlb_miss_lock if DEBUG is defined, even if it's not otherwise
required.
