- Convert x86 MD code, mainly pmap(9) e.g. TLB shootdown code, to use
  kcpuset(9) and thus replace hardcoded CPU bitmasks.  This removes the
  limitation of maximum CPUs.

- Support up to 256 CPUs on amd64 architecture by default.

Bug fixes, improvements, completion of Xen part and testing on 64-core
AMD Opteron(tm) Processor 6282 SE (also, as Xen HVM domU with 128 CPUs)
by Manuel Bouyer.

Enable the NX bit feature early in the MP trampoline code (do not rely on
cpu_init_msrs() to do it). Having NX bit set on a page will raise a #GP
on fetch if NXE is not enabled, which can happen early when structures
(like idlelwp) are allocated with just rw- rights.

This patch fixes the NX regression issue observed on amd64 kernels, where
per-page execution right was disabled (therefore leading to the inability
of the kernel to detect fraudulent use of memory mappings marked as not
being executable).

- replace cpu_feature and ci_feature_flags variables by cpu_feature and
ci_feat_val arrays. This makes it cleaner and brings kernel code closer
to the design of cpuctl(8). A warning will be raised for each CPU that
does not expose the same features as the Boot Processor (BP).

- the blacklist of CPU features is now a macro defined in the
specialreg.h header, instead of hardcoding it inside MD initialization
code; fix comments.

- replace checks against CPUID_TSC with the cpu_hascounter() function.

- clean up the code in init_x86_64(), as cpu_feature variables are set
inside cpu_probe().

- use cpu_init_msrs() for i386. It will be eventually used later for NX
feature under i386 PAE kernels.

- remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already
performed by cpu_hatch() through cpu_init_msrs().

- remove cpu_signature and feature_flags members from struct mpbios_proc
(they were never used).

This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under
a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines.

XXX Should kernel rev be bumped?

XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

- 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.

Be more conservative during AP startup. Don't let the AP access the lapic
or do any setup until the boot processor has finished the init sequence,
and add a few more delays.

merge yamt-x86pmap branch.

- reduce differences between amd64 and i386.  notably, share pmap.c
  between them.  it makes several i386 pmap improvements available to
  amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option.  always use large pages if available.
  also, make it work on amd64.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Rename the x86_64 port to amd64, as this is the actual name used for
the processor family now. x86_64 is kept as the MACHINE_ARCH value,
since it's already widely used (by e.g. the toolchain, etc), and
by other operating systems.
