3647e0d293 Merge cpu_sysctl() for all mips ports, based on powerpc and m68k precedent. 
For now, only pmax implements CPU_BOOTED_KERNEL.  Need to revisit.

810cde53cc use a completely separate trap handler for syscall traps. 
this reduces syscall overhead by 10% to 20% depending on cpu type.

036da55e8f Add support for the Intel i80321 I/O Processor's Application Accelerator 
Unit.  The AAU provides block fill, block copy, XOR, and XOR-parity-check
operations.  We currently provide dmover(9) functions for "zero", "fill8",
and "copy".

Much of this code can be shared with the i80312 Companion I/O AAU, and
will be when support for the older chip is implemented.

dce4476374 Overhaul how DMA ranges work in the ARM bus_dma implementation. 
A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length.  In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

4464952a27 Use evbmips/evbmips/conf_common.c since the sbmips port's conf.c was 
mostly in-sync with the evbmips one.  The kttcp device has changed
device number; users who have created that will need to re-create it.

79af00bddb Move the calls to uvm_page_physload() out of pmap_bootstrap() and 
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical.  Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

3fe600dd5c Experimentation reveals that the implementation of GET_ENV on at least 
some systems chokes if the buffer is not 8-byte aligned. GCC only aligns
character arrays to 4-byte boundaries by default, so it's possible to get
unlucky and die in the boot blocks with a "kernel stack not valid halt".

Avoid the problem by using a local, aligned buffer as the argument to GET_ENV,
and copying the result into the caller's buffer.

Should fix PRs port-alpha/17682 and port-alpha/17717.
