218fd301cd pmap_kremove can no longer be used to remove the magic device mappings
installed with pmap_kenter_flags, since the physical addresses may not
have an associated vm_page.  Add a function to do this.

2f9267ec23 Move the "- 1" into the RQB_FFS(mask) macro itself so that
implementations can provide a base zero ffs function if they wish.
This changes
  #define RQB_FFS(mask) (ffs64(mask))
  foo = RQB_FFS(mask) - 1;
to
  #define RQB_FFS(mask) (ffs64(mask) - 1)
  foo = RQB_FFS(mask);
On some platforms we can get the "- 1" for free, eg: those that use the
C code for ffs64().

e3957e9d67 Add constants for the min and max prom addresses. Use these instead of
magic numbers.  Use stxa_sync instead of stxa; membar #Sync; to ensure
that no instruction is placed between the two.  This can cause random
corruption even though interrupts are already disabled.

acb941ef8f Fix bizarre SMP problems. The secondary cpus sometimes start up with junk
in their tlb which the prom doesn't clear out, so we have to do so manually
before mapping the kernel page table or the cpu can hang due various
conditions which cause undefined behaviour from the tlb.

20bd6675fb Add an MD page flag for tracking if a page is cacheable or not, so that
we don't flush all mappings of a physical page in order to make it
virtually cachable again, if it is already cachable.

1982efc5c2 Merge the code in pv.c into pmap.c directly. Place all page mappings onto
the pv lists in the vm_page, even unmanaged kernel mappings.  This is so
that the virtual cachability of these mappings can be tracked when a page
is mapped to more than one virtual address.  All virtually cachable
mappings of a physical page must have the same virtual colour, or illegal
alises can be created in the data cache.  This is a bit tricky because we
still have to recognize managed and unmanaged mappings, even though they
are all on the pv lists.

025c284b8d Add a support macro to convert the 5-bit packed register field of
a floating point instruction into a 6-bit register number for
double and quad arguments.
Make use of the new INSFPdq_RN macro where apporpriate; this
is required for correctly handling the "high" fp registers
(>= %f32).
Fix a number of bugs related to the handling of the high registers
which were caused by using __fpu_[gs]etreg() where __fpu_[gs]etreg64()
should be used (the former can only access the low, single-precision,
registers).

db17c6fc07 Tidy up some loose ends.
i386/ia64/alpha - catch up to sparc64/ppc:
- replace pmap_kernel() with refs to kernel_pmap
- change kernel_pmap pointer to (&kernel_pmap_store)
  (this is a speedup since ld can set these at compile/link time)
all platforms (as suggested by jake):
- gc unused pmap_reference
- gc unused pmap_destroy
- gc unused struct pmap.pm_count
(we never used pm_count - we track address space sharing at the vmspace)

182da8209d Stage-2 commit of the critical*() code. This re-inlines cpu_critical_enter()
and cpu_critical_exit() and moves associated critical prototypes into their
own header file, <arch>/<arch>/critical.h, which is only included by the
three MI source files that need it.

Backout and re-apply improperly comitted syntactical cleanups made to files
that were still under active development.  Backout improperly comitted program
structure changes that moved localized declarations to the top of two
procedures.  Partially re-apply one of the program structure changes to
move 'mask' into an intermediate block rather then in three separate
sub-blocks to make the code more readable.  Re-integrate bug fixes that Jake
made to the sparc64 code.

Note: In general, developers should not gratuitously move declarations out
of sub-blocks.  They are where they are for reasons of structure, grouping,
readability, compiler-localizability, and to avoid developer-introduced bugs
similar to several found in recent years in the VFS and VM code.

d86b2422b9 Move the CTASSERT macro from MD code to systm.h alongside KASSERT so other
code can use it.  This takes a single constant argument and fails to compile
if it is 0 (false).  The main application of this is to make assertions about
structure sizes at compile time, in order to validate assumptions made in
other code.  Examples:

CTASSERT(sizeof(struct foo) == FOO_SIZEOF);
CTASSERT(sizeof(struct foo) == (1 << FOO_SHIFT));

d74ac6819b Compromise for critical*()/cpu_critical*() recommit. Cleanup the interrupt
disablement assumptions in kern_fork.c by adding another API call,
cpu_critical_fork_exit().  Cleanup the td_savecrit field by moving it
from MI to MD.  Temporarily move cpu_critical*() from <arch>/include/cpufunc.h
to <arch>/<arch>/critical.c (stage-2 will clean this up).

Implement interrupt deferral for i386 that allows interrupts to remain
enabled inside critical sections.  This also fixes an IPI interlock bug,
and requires uses of icu_lock to be enclosed in a true interrupt disablement.

This is the stage-1 commit.  Stage-2 will occur after stage-1 has stabilized,
and will move cpu_critical*() into its own header file(s) + other things.
This commit may break non-i386 architectures in trivial ways.  This should
be temporary.
