Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.

Sync MAXfoo params with oea:

MAXTSIZ: 512MB -> 128MB
MAXDSIZ: 3.25GB -> 1GB

There should be no particular reasons for having different values.

PR port-powerpc/56107

Decrease MAXSSIZ from ~256MB to 32MB (same as oea).

This fixes tests in /usr/tests/usr.bin/make, that run with "ulimit -v 200000",
fail with "Cannot map anonymous memory".

Although I'm not fully convinced whether this limit is reasonable or not,
old MAXSSIZ of ~256MB is too much anyway.

move common tlb stuff to uvm

Allow the use of the full 4GB address space.

PowerPC now exports a common view of cpu.h, vmparam.h and pmap.h
when building a MODULAR kernel or compiling _MODULE.
It should be noted that MODULAR or _MODULE export a view of the kernel
as being MULTIPROCESSOR (even if isn't).
The shared pmap TLB uses mdpg in places where it used mdpg to avoid
deadly embrance inclusion problems.

Remove <machine/atomic.h>; use <sys/atomic.h> instead.
Add <powerpc/cpuset.h> (for mpc85xx pmap).
Add some initial MP code for mpc85xx
Rework ipi code to be common across all ppcs
Change PPC to keep curlwp in %r13 while in the kernel.
Move astpending from cpu_info to mdlwp
Improve cpu_need_resched to be more MP friendly.

branches: 1.3.4;
Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.

Remove incomplete, never worked dynamic run-time memory registration
(uvm_page_physload(9)). This functionality will be re-added later.

branches: 1.1.2; 1.1.4; 1.1.6;
Add initial versions of these for BookE.
