Provide MI PMAP support on AARCH64

Use sys/uvm/pmap/pmap_tlb.c on Aarch64 in the same way that some Arm, MIPS,
and some PPC kernels do.  This removes the limitation of 256 processes on
CPUs with 8bit ASID field, e.g. Apple M1.

Additionally the following changes have been made

- removed a couple of unnecessary aarch64_tlbi_all calls
- removed any invalidation after freeing page tables due to
  _pmap_sweep_pdp. This was never necessary afaict.
- all kernel mappings are marked global and userland mapping not-global.

Performance testing hasn't show a significant difference.  The data here
is from building a kernel on an lx2k system with nvme.

Make tlb_asid_t unsigned int as pmap_tlb.c expects tlb_asid_t to be able to
hold ASID_MAX + 1.

Add __HAVE_BUS_SPACE_8

PID_MAX is just an initial value (soft maximum). Don't use it for CTASSERT.
defined __HAVE_CPU_MAXPROC to use function cpu_maxproc().

Implement MD ucas(9) (__HAVE_UCAS_FULL)

sort __HAVE_* defines.  NFCI

Remove __HAVE_CPU_LWP_SETPRIVATE from aarch64

aarch64 specific cpu_lwp_setprivate() is redundant with its caller
lwp_setprivate() and there are no MD bits.

Be consistent and explicitly size register32_t too.

match declaration types for registers from reg.h

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

 * Removes "options PERFCTRS", the associated includes, and the associated
   ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
   good.

 * Removes the PMC code of ARM XSCALE.

 * Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

 * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
   definitions are put in sysarch.h.

 * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
   and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
   netbsd32 and rump.

 * Removes the pmc_evid_t and pmc_ctr_t types.

 * Removes all the associated man pages. The sets are marked as obsolete.

Define __HAVE_OLD_DISKLABEL for compatibility with the arm32 port.

Reorder using register_t to the point where it is defined.

expose the kernel types for standalone code.

Hide {p,v}{addr,size}_t and register_t (and a couple more types that
are machine-specific) from userland unless _KERNEL/_KMEMUSER and a
new _KERNTYPES variables is defined. The _KERNTYPES should be fixed
for many subsystems that should not be using it (rump)...

Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant
pthread types in C++ builds, attempt 2.

The problem with attempt 1 was making assumptions of what the MD
__cpu_simple_lock_t (declared volatile) looks like.  To get a same type
except non-volatile, we change the MD type to __cpu_simple_lock_nv_t
and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t.
IMO, __cpu_simple_lock_t should not be volatile at all, but changing it
now is too risky.

Fixes at least Rumprun w/ gcc 5.1/5.2.  Furthermore, the mpd application
(and possibly others) will no longer require NetBSD-specific patches.

Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2.

Based on the patch from Christos in lib/49989.

Rebase to HEAD as of a few days ago.

file types.h was added on branch tls-maxphys on 2014-08-20 00:02:39 +0000

Preliminary files for AARCH64 (64-bit ARM) support.
Enough for a distribution build.
