<arm/locore.h> fallout (fixes some include ordering errors)

branches: 1.21.2;
Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.

Move the standard definitions of the {UND,IRQ,FIQ,ABT}_STACK_SIZE to

As md(4) no longer has "needs-count" there is no "md.h" anymore.
Remove the inclusion of this file.

Acorn32 now always builds load_memory_disc_from_floppy(). This should
not be a problem as all configs have md(4).

Use cpu_* prefix to call cpu_* functions (setttb() -> cpu_setttb()); no
functional changes.

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.

Kill proc0paddr. Use lwp0.l_addr instead.

Remove all declarations of physmem from sys/arch. Add an include of
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)

evaluate RMCR correctly for single proc gemini

add bootstrap ttbl and devmap entries for DRAM Controller
and sanity check memory remap reg to catch possible
mismatch between boot firmware remapping and kernel MEMSIZE, etc.

add gemini_cpu1_start() so Master CPU can release Slave to boot.
this gets called early in initarm(); this is as early as reasonable
for now; we might have to puch it back if the Slave ever depends
on the Master to do some setup work or something.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

- use actual device address defines instead of abstract console defines for in mmu_init_table\gemini_start.S and devmap[]\gemini_machdep.c;
this allows some flexibility e.g. to map 'em all, which is useful
e.g. when using obio uart to debug lpc uart.

- add mmu_init_table entries for Gemini global regs, lpchc, and lpcio
these are needed to consinit() when console is lpc uart

- now have 2 versions of consinit, one for obio uart,
the other for lpc uart; we use CONSADDR to determine
which gets compiled.

- remove a useless bus_space map/unmap from obio uart version of consinit
comcnattach() will do his own...

- initarm progress putchars and printfs are now #ifdef VERBOSE_INIT_ARM
- use GEMINI_SLAVE, GEMINI_MASTER defines to distinguish between
primary and secondary CPUs, who owns what devices, etc.
- add short delay()s to allow console printf output to drain before reset
unless if ref_sc is not yet initialized, in which case tough.
- add devmap entriy for LPC
- add devmap entry for RAMDISK if MEMORY_DISK_DYNAMIC is defined
i.e. if the ramdisk is external to the kernel, in which case
we "know" where is lives by agreement with firmware.
- call md_root_setconf() if MEMORY_DISK_DYNAMIC is defined
