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.

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.
This revision does the following renames:
CPU_MIPS24KC -> CPU_MIPS24K
CPU_MIPS74KC -> CPU_MIPS74K
CPU_MIPS1004KC -> CPU_MIPS1004K
It also adds the following new CPU_MIPSxxx options:
CPU_MIPS24KE, CPU_MIPS34K, CPU_MIPS1074K, CPU_INTERAPTIV, CPU_PROAPTIV
CPU_MIPSxxxxKC is limiting and possibly misleading as it implies the
MIPSxxxxK CPU has no FPU.
It would be better if the CPUs are named after their standard functionalities
only and the presence or absence of FPU can then be controlled via the
CPU_HAVEFPU option.
I will send out another dependent revision that moves MIPS 32 r2 and r3
CPUs to use the EHB instruction for clearing hazards instead of NOP/SSNOP.

MD_ROOT_SIZE and embed_mfs.sh were basically retired as part of
https://reviews.freebsd.org/D2903 .
However, when building a kernel with 'options MD_ROOT_SIZE' specified, this
results in a non-working MFS, as within sys/dev/md/md.c we fall within the
wrong # ifdef.
This patch implements the following:
* Allow kernels to be built without the MD_ROOT_SIZE option, which results
in a kernel built as per D2903.
* Allow kernels to be built with the MD_ROOT_SIZE option, which results
in a kernel built similarly to the pre-D2903 way, with the following
differences:
* The MFS is now put in a separate section within the kernel (oldmfs,
so it differs from the mfs section introduced by D2903).
* embed_mfs.sh is changed, so it looks up the oldmfs section within the
kernel, gets its size and offset, sees if the MFS will fit within the
allocated oldmfs section and only if all is well does a dd of the MFS
image into the kernel.

The PT_{GET,SET}FPREGS requests use 'struct fpreg' and the NT_FPREGSET
core note stores a copy of 'struct fpreg'. As with x86 and the floating
point state there compared to the extended state in XSAVE, struct fpreg
on powerpc now only holds the 'base' FP state, and setting it via
PT_SETFPREGS leaves the extended vector state in a thread unchanged.

During the update process in sa_modify_attrs(), the sizes of existing
variably-sized SA entries are obtained from sa_lengths[]. The case where
a variably-sized SA was being replaced neglected to increment the index
into sa_lengths[], so subsequent variable-length SAs would be rewritten
with the wrong length. This patch adds the missing increment operation
so all variably-sized SA entries are stored with their correct lengths.
Another problem was that index into attr_desc[] was increased even when
an attribute was removed. If that attribute was not the last attribute,
then the last attribute was lost.
The variable isn't actually checked -- just the end result which gets
returned from the function
