The stack must be aligned to 16 bytes at all times. Clang 3.8 is especially
adamant about this, and causes strange behavior and segmentation faults if it is
not the case.

Device trees mark lbc as compatible with simplebus. Since simplebus is passed
first, it attaches first. When lbc's pass (default pass) comes, the bus is
already attached to simplebus, so is skipped.

sysrc(8) supports key+=value and key-=value, but can be told what the
delimiter is by being passed as char1 (e.g., "sysrc key+=",value" to use a
comma as the delimiter instead of space). For convenience, if the first char
is alpha-numeric, it is assumed you wanted whitespace as the delimiter.
However, if you naively (as I just did) execute:
sysrc rc_conf_files+=/etc/rc.conf.other
the result is unexpected.
This commit makes `.' and `/' in-addition to alpha-numeric first-characters
to cause the default of whitespace to be used as the delimiter. This also
means that you can no longer use these as a delimiter.
When using col(1) piped to vim(1) as pager for man(1), the former sequence
of (Qo \ Qc) renders as "" without the space. Replace with (Qo (space) Qc)
which renders properly in more (all?) pagers.

after old pmap-v6 code was removed.
For compatibility with __ARM_ARCH < 6, define PTE_DEVICE in devmap.c
file. Certainly, it would be nice if VM_MEMATTR_DEVICE could be used
even for __ARM_ARCH < 6.
do not depend on pmap internals. This is a preparation for hiding
internal pmap definitions as much as possible from the rest of system.
Simultaneously, the protection argument evaluation is fixed. Happily,
it did not effect the mappings. And it's the reason why it was not fixed
earlier.
Only 'installworld' needs to be protected and only when not using
-DNO_ROOT, which implies not installing to / and not needing the
lib dependency protections.

clearing hazards.
This revision makes currently known MIPS32 Release 2 and Release 3 CPUs use
the EHB instruction when clearing hazards. So far the MIPS 74K and MIPS1004K
(somewhat) were already using the EHB. Now we add more r2 and r3 CPUs to
this list.
Also, for the cases of MIPS coherent processing systems (currently 1004K,
1074K, interAptiv and proAptiv) - define proper CCA attributes.

Since we have iconv in our libc these days, we don't
need it on 10.X and later. However, 9.X still need

function is only called from vm_page_startup() and vm_reserv_startup().
I.e. during vm subsystem initialization. As VM_PROT_WRITE is always
used in these calls, the typo did not have any effect. Likely, it's
the reason why it wasn't discovered so long.
