sys: use our roundup2/rounddown2() macros when param.h is available.
rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement.
This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted.

Make kstack_pages a tunable on arm, x86, and powepc. On i386, the initial thread stack is not adjusted by the tunable, the stack is allocated too early to get access to the kernel environment. See TD0_KSTACK_PAGES for the thread0 stack sizing on i386.
The tunable was tested on x86 only. From the visual inspection, it seems that it might work on arm and powerpc. The arm USPACE_SVC_STACK_TOP and powerpc USPACE macros seems to be already incorrect for the threads with non-default kstack size. I only changed the macros to use variable instead of constant, since I cannot test.
On arm64, mips and sparc64, some static data structures are sized by KSTACK_PAGES, so the tunable is disabled.

Fix KSTACK_PAGES issue when the default value was changed in KERNCONF
If KSTACK_PAGES was changed to anything alse than the default, the value from param.h was taken instead in some places and the value from KENRCONF in some others. This resulted in inconsistency which caused corruption in SMP envorinment.
Ensure all places where KSTACK_PAGES are used the opt_kstack_pages.h is included.
The file opt_kstack_pages.h could not be included in param.h because was breaking the toolchain compilation.

When mapping device memory, use PTE_DEVICE rather than PTE_NOCACHE. On armv4 these are defined as synonyms right now, but it's a bit ambiguous what NOCACHE means (is buffering/write-combining also enabled or not?); this is a first step towards replacing PTE_NOCACHE with a less ambiguous name.

The arm exception entry points currently vector through a function pointer to the actual handler routine. All the pointers are static-intialized to the only handlers available, and yet various platform-specific inits still set those pointers (to the values they're already initialized to). Begin to drain the swamp by removing all the redundant external declarations and runtime setting of the pointers that's scattered around various places.

It turns out a global variable is the only straightforward way to communicate the kernel's physical load address from where it's known in initarm() into cpu_mp_start() which is called from non-arm code and takes no parameters.
This adds the global variable and ensures that all the various copies of initarm() set it. It uses the variable in cpu_mp_start(), eliminating the last uses of KERNPHYSADDR outside of locore.S (where we can now calculate it instead of relying on the constant).

Consolidate code related to setting up physical memory configuration into a new physmem.c file. The new code provides helper routines that can be used by legacy SoCs and newer FDT-based systems. There are routines to add one or more regions of physically contiguous ram, and exclude one or more physically contiguous regions of ram. Ram can be excluded from crash dumps, from being given over to the vm system for allocation management, or both. After all the included and excluded regions have been added, arm_physmem_init_kernel_globals() processes the regions into the global dump_avail and phys_avail arrays and realmem and physmem variables that communicate memory configuration to the rest of the kernel.
Convert all existing SoCs to use the new helper code.

Remove the ARM_USE_SMALL_ALLOC option and code related to it.
This was an optimization used only by a few xscale platforms. Part of the optimization was to create a direct map for all physical pages, and that resulted in making multiple mappings of pages in a way that bypassed the logic in pmap.c to handle VIVT cache aliasing. It also just generally made the code more complex and hard to maintain for all SoCs.

Move remaining code and data related to static device mapping into the new devmap.[ch] files. Emphasize the MD nature of these things by using the prefix arm_devmap_ on the function and type names (already a few of these things found their way into MI code, hopefully it will be harder to do by accident in the future).

Create a common set_stackptrs in sys/arm/machdep.c.
On single core devices set_stackptrs is only ever called with cpu = 0 in initarm and will be identical to the existing function. On SMP this needs to be implemented for sys/arm/mp_machdep.c, but the implementations are identical for each SoC.

Implement a facility for dynamic per-cpu variables. - Modules and kernel code alike may use DPCPU_DEFINE(), DPCPU_GET(), DPCPU_SET(), etc. akin to the statically defined PCPU_*. Requires only one extra instruction more than PCPU_* and is virtually the same as __thread for builtin and much faster for shared objects. DPCPU variables can be initialized when defined. - Modules are supported by relocating the module's per-cpu linker set over space reserved in the kernel. Modules may fail to load if there is insufficient space available. - Track space available for modules with a one-off extent allocator. Free may block for memory to allocate space for an extent.

Support for the XScale PXA255 SoC as found on the Gumstix Basix and Connex boards. This is enough to net-boot to multiuser.
Also supported is the SMSC LAN91C111 parts used on the netCF, netDUO and netMMC add-on boards.
I'll be putting some instructions on how to boot this on the Gumstix boards online soon.
This is still fairly rough and will be refined over time but I felt it was better to get this out there where other people can help out.
