99bd783419 Move the definition of ElfN_Hashelt to common headers. The only platform
which has a different definition for this is alpha.

60c6f9b332 Remove the definition of struct mca_guid and use the generic
struct uuid defined in <sys/uuid.h>.

Use uuid/UUID instead of guid/GUID to emphasize that the
identifiers are DCE version 1 identifiers and also to avoid
inconsistencies as much a possible.

424f97a066 Fix a kernel page fault when accessing user memory. We were
combining too much conditions and as such ended up with the
kernel map instead of the corresponding process map. While
here, remove code to allow access to the stackgap and restyle
slightly to improve readability.

This fix specifically fixes the procfs failure we're having
when reading the process map (cat /proc/curproc/map)

8869375945 Simplify IA64_CMPXCHG to avoid having braced-groups in expressions.
As a minor positive side-effect, code at -O0 is more optimal. As a
minor negative side-effect, certain boundary cases yield no better
code than non-boundary cases. For example, atomic_set_acq_32(p, 0)
does a useless logical OR with value 0. This was previously elimina-
ted as part of if/while optimizations. Non-boundary cases yield
identical code at -O1 and -O2.

f5b454cf25 o Rename ia64_count_aps to ia64_count_cpus and reimplement the
function to return the total number of CPUs and not the highest
   CPU id.
o  Define mp_maxid based on the minimum of the actual number of
   CPUs in the system and MAXCPU.
o  In cpu_mp_add, when the CPU id of the CPU we're trying to add
   is larger than mp_maxid, don't add the CPU. Formerly this was
   based on MAXCPU. Don't count CPUs when we add them. We already
   know how many CPUs exist.
o  Replace MAXCPU with mp_maxid when used in loops that iterate
   over the id space. This avoids a couple of useless iterations.
o  In cpu_mp_unleash, use the number of CPUs to determine if we
   need to launch the CPUs.
o  Remove mp_hardware as it's not used anymore.
o  Move the IPI vector array from mp_machdep.c to sal.c. We use
   the array as a centralized place to collect vector assignments.
   Note that we still assign vectors to SMP specific IPIs in
   non-SMP configurations. Rename the array from mp_ipi_vector to
   ipi_vector.
o  Add IPI_MCA_RENDEZ and IPI_MCA_CMCV. These are used by MCA.
   Note that IPI_MCA_CMCV is not SMP specific.
o  Initialize the ipi_vector array so that we place the IPIs in
   sensible priority classes. The classes are relative to where
   the AP wake-up vector is located to guarantee that it's the
   highest priority (external) interrupt. Class assignment is
   as follows:
	class	IPI		notes
	x	AP wake-up	(normally x=15)
	x-1	MCA rendezvous
	x-2	AST, Rendezvous, stop
	x-3	CMCV, test

9a1bf46934 Make sure we don't index the pm_rid array out of bounds in
pmap_ensure_rid(). This can happen because the function is
called for both user and kernel addresses, while the rid array
only has room for user addresses. This bug got exposed by rev
1.58 of ia64/ia64/pmap.c and rev 1.8 of ia64/include/pmap.h.

1f0fa5e154 Add ar.lc and ar.ec to the trapframe. These are not saved for syscalls,
only for exceptions.

While adding this to exception_save and exception_restore, it was hard
to find a good place to put the instructions. The code sequence was
sufficiently arbitrarily ordered that the density was low (roughly 67%).
No explicit bundling was used.
Thus, I rewrote the functions to optimize for density (close to 80% now),
and added explicit bundles and nop instructions. The immediate operand
on the nop instruction has been incremented with each instance, to make
debugging a bit easier when looking at recurring patterns. Redundant
stops have been removed as much as possible. Future optimizations can
focus more on performance. A well-placed lfetch can make all the
difference here!

Also, the FRAME_Fxx defines in frame.h were mostly bogus. FRAME_F10 to
FRAME_F15 were copied from FRAME_F9 and still had the same index. We
don't use them yet, so nothing was broken.

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)

e477773f01 Machine Check Architecture (MCA) support code. Error records are
collected at boot and made available through sysctl(8). At the
moment, the following MIB names are created:

	hw.mca.count	- The number of error records collected.
	hw.mca.first	- The lowest sequence number present.
	hw.mca.last	- The highest sequence number present.
	hw.mca.<X>	- The error record with sequence number <X>.

Using sysctl(8) allows us to easily detect and analyze the records,
which is very helpful during development of MCA but can also be used
in production as a way to collect machine health statistics.

d297ad160e Don't use the symbol name to lookup the symbol value when we can use
the symbol index defined by the relocation. The elf_lookup() support
function is to be used by elf_reloc() when symbol lookups need to be
done. The elf_lookup() function operates on the symbol index and
will do a symbol name based lookup when such is required, otherwise
it uses the symbol index directly. This solves the problem seen on
ia64 where the symbol hash table does not contain local symbols and
a symbol name based lookup would fail for those symbols.

Don't pass the symbol name to elf_reloc(), as it isn't used any more.

d435ac4e91 Add ia64_sal_init_state(). This function will initialize the machine
check handling. In its current form, it only determines the largest
amount of state information it can get from SAL and allocates a region
7 memory block for it.

The next steps involve:
o  get and log any unconsumed (NVM stored) error records across
   reboots,
o  register an OS_MCA handler and enable machine checks.
