riastradh | mips: Align stack pointer on entry to signal handler.
Based on a patch by rin@. The variant approach I took puts the stack
frame allocation and alignment logic in one place (getframe, used by
sendsig_siginfo for native (n64, on mips), netbsd32_sendsig_siginfo
for compat32 (n32/o32, on mips), and sendsig_sigcontext (compat 1.6))
and reduces the chance of provoking compiler exploitation of
undefined behaviour by doing arithmetic in uintptr_t rather than in
pointers to large aligned structs. This also ensures the resulting
pointer is aligned for the object (struct siginfo_sigframe, struct
siginfo_sigframe32, struct sigcontext), not just for the ABI stack
alignment.

this has been returning "mipsn64eb" on my edgerouter4 with the
32 bit uname binary.
introduce o32, n32, and n64 versions of MACHINE_ARCH, and use
them appropriately in PROC_MACHINE_ARCH32(). now o32, n32 and
n64 "uname -p" all return different values.

Define a UPAGES_MAX constant to size the a md_upte array in MIPS's
struct mdlwp. This is exposed to userland, so we can't use something
based on PAGE_SIZE.

simonb | Use a 16kB USPACE (and larger kernel stack) for LP64 kernels. Invert
the logic for setting the USPACE size. Define a desired USPACE size
(16kB for LP64, 8kB otherwise) then divide by PAGE_SIZE to get UPAGES.
Fixes random segmap lossage, since the uarea usually sits immediately
above the segmap for a process. Thanks to mrg@, skrll@ and dholland@
for testing, debugging and general help tracking down this problem.

from the IPv6 aux data migration. It broke the historic ABI on some

platforms and provides a template for future changes to the CMSG_*

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.
The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

castor | * Create mips_reg_t data type to allow register size to be
decoupled from long or int or long long. Define macros in asm.h to facilitate
choosing these on a port by port basis.
* Create <machine/pubassym.h> mechanism to allow jmp_buf structure size
to be calculated at system build time.
* Define _MIPS_BSD_SIM macro which specifies what calling style is appropritae
for the architecture. For 64-bit oriented systems set the Status Register
to allow 64-bit instructions.
* Remove UADDR related macros because kernel U structure is now mapped
normally.
* Separate cpu.h into cpu.h and cpuarch.h to keep things neat.
* Add support for QED 52xx processors

jonathan | Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>.
Adds (most) support for ARC platform to port-independent mips code.
Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.
Open issues:
* Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
Code derived from Per Fogelstrom's OpenBSD source doesn't work
on mips3 pmaxes with L2 cache.
* Still some port-specific #ifdefs, for interrupt enable and
pmax L2 cache-size. Needs more thought, but overlaps with
work-in-progress by Tohru and Tsubai on spl()s and related stuff.
