If we get a fault setting the user %gs, or on a iret that is returning
to userspace, we must do a 'swapgs' to reload the kernel %gs_base.
Also save the %ds, %es, %fs, %gs selector values in the frame so
they can be restored if we finally return to user (probably after
an application SIGSEGV handler has fixed the error).
Without this any such fault leaves the kernel running with the wrong
%gs offset and it will most likely fault again early in trap().
Repeats until the stack tramples on something important.
iret change works, invalid %gs is a little harder to arrange.

Rejig the way TRAP() and ZTRAP() are defined and add Z/TRAP_NJ() that
  excludes the 'jmp alltraps'.
Use the _NJ versions for trap entries with non-standard code.
Move all the KDTRACE_HOOKS code into a single block inside the
  IDTVEC(trap03) code. This removes a mis-predicted from every
  trap when KDTRACE_HOOKS are enabled.
Add a few blank lines, need some comments as well :-)
No functional changes intended.

Alignment fault traps push the error code automatically, so don't use ZTRAP!

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Ephemeral mapping (emap) implementation.  Concept is based on the idea that
activity of other threads will perform the TLB flush for the processes using
emap as a side effect.  To track that, global and per-CPU generation numbers
are used.  This idea was suggested by Andrew Doran; various improvements to
it by me.  Notes:

- For now, zero-copy on pipe is not yet enabled.
- TCP socket code would likely need more work.
- Additional UVM loaning improvements are needed.

Proposed on <tech-kern>, silence there.

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.
