Revert most of ad's movs/stos change. Instead do a lot simpler: declare
svs_quad_copy() used by SVS only, with no need for instrumentation, because
SVS is disabled when sanitizers are on.

Serialize rdtsc using with lfence, mfence or cpuid to read TSC more precisely.

 x86/x86/tsc.c rev. 1.67 reduced cache problem and got big improvement, but it
 still has room. I measured the effect of lfence, mfence, cpuid and rdtscp.
The impact to TSC skew and/or drift is:

	AMD:   mfence > rdtscp > cpuid > lfence-serialize > lfence = nomodify
	Intel: lfence > rdtscp > cpuid > nomodify

So, mfence is the best on AMD and lfence is the best on Intel. If it has no
SSE2, we can use cpuid.

NOTE:
  - An AMD's document says DE_CFG_LFENCE_SERIALIZE bit can be used for
    serializing, but it's not so good.
  - On Intel i386(not amd64), it seems the improvement is very little.
  - rdtscp instruct can be used as serializing instruction + rdtsc, but
    it's not good as [lm]fence. Both Intel and AMD's document say that
    the latency of rdtscp is bigger than rdtsc, so I suspect the difference
    of the result comes from it.

Move x86_hotpatch() in !XENPV section. Fixes XEN3* builds.

Modify the hotpatch mechanism, in order to make it much less ROP-friendly.

Currently x86_patch_window_open is a big problem, because it is a perfect
function to inject/modify executable code with ROP.

 - Remove x86_patch_window_open(), along with its x86_patch_window_close()
   counterpart.
 - Introduce a read-only link-set of hotpatch descriptor structures,
   which reference a maximum of two read-only hotpatch sources.
 - Modify x86_hotpatch() to open a window and call the new
   x86_hotpatch_apply() function in a hard-coded manner.
 - Modify x86_hotpatch() to take a name and a selector, and have
   x86_hotpatch_apply() resolve the descriptor from the name and the
   source from the selector, before hotpatching.
 - Move the error handling in a separate x86_hotpatch_cleanup() function,
   that gets called after we closed the window.

The resulting implementation is a bit complex and non-obvious. But it
gains the following properties: the code executed in the hotpatch window
is strictly hard-coded (no callback and no possibility to execute your own
code in the window) and the pointers this code accesses are strictly
read-only (no possibility to forge pointers to hotpatch an area that was
not designated as hotpatchable at compile-time, and no possibility to
choose what bytes to write other than the maximum of two read-only
templates that were designated as valid for the given destination at
compile-time).

With current CPUs this slightly improves a situation that is already
pretty bad by definition on x86. Assuming CET however, this change closes
a big hole and is kinda great.

The only ~problem there is, is that dtrace-fbt tries to hotpatch random
places with random bytes, and there is just no way to make it safe.
However dtrace is only in a module, that is rarely used and never compiled
into the kernel, so it's not a big problem; add a shitty & vulnerable
independent hotpatch window in it, and leave big XXXs. It looks like fbt
is going to collapse soon anyway.

Rollback http://mail-index.netbsd.org/source-changes/2018/12/22/msg101629.html

This change breaks module loading due to weak alias being unsupported
in the kernel module linker.

Requested by maxv@ and others as it affects their work.

No immediate decision on a replacement method is available, but other options
suggested include pre-processing, conditional compilation (#ifdef etc) and other
source level methods to avoid linktime decision making.

Changes since 1.25: +18 -6 lines
Diff to previous 1.25 (colored) 

Introduce a weak alias method of exporting different implementations
of the same API.

For eg: the amd64 native implementation of invlpg() now becomes
amd64_invlpg() with a weak symbol export of invlpg(), while the XEN
implementation becomes xen_invlpg(), also weakly exported as invlpg()

Note that linking in both together without having an override function
named invlpg() would be a mistake, as we have limited control over
which of the two options would emerge as the finally exported invlpg()
resulting in a potential situation where the wrong function is finally
exported. This change avoids this situation.

We should however include an override function invlpg() in that case,
such that it is able to then pass on the call to the appropriate
backing function (amd64_invlpg() in the case of native, and
xen_invlpg() in the case of under XEN virtualisation) at runtime.

This change does not introduce such a function and therefore does not
alter builds to include native as well as XEN implementations in the
same binary. This will be done later, with the introduction of XEN
PVHVM mode, where precisely such a runtime switch is required.

There are no operational changes introduced by this change.

Fix for i386, functionality intended in:
http://mail-index.netbsd.org/source-changes/2018/09/23/msg099357.html

This should fix the build for both GENERIC and XEN3PAE_DOM0

This has not been boot tested on native or xen3pae

Notes: pmap_changeprot_local() seems to be x86_64 only.
I was a bit surprised by this initially, but I suspect that the table
protections are enforced via ring0/ring1 fencing rather than page protections

the gdt registration code in i386 is still messy. I will leave it as is
for now - to avoid a rabbit hole.

Drop NENTRY() from the x86 kernels, use ENTRY(). With PMCs (and other hardware
tracing facilities) we have a much better ways of monitoring the CPU activity
than GPROF, without software modification.

Also I think GPROF has never worked, because the 'start' functions of both
i386 and amd64 use ENTRY(), and it would have caused a function call while the
kernel was not yet relocated.

Add support for saving the AVX-256 ymm registers during FPU context switches.
Add support for the forthcoming AVX-512 registers.
Code compiled with -mavx seems to work, but I've not tested context
  switches with live ymm registers.
There is a small cost on fork/exec (a larger area is copied/zerod),
  but I don't think the ymm registers are read/written unless they
  have been used.
The code use XSAVE on all cpus, I'm not brave enough to enable XSAVEOPT.

Change i386 to use x86/fpu.c instead of i386/isa/npx.c
This changes the trap10 and trap13 code to call directly into fpu.c,
  removing all the code for T_ARITHTRAP, T_XMM and T_FPUNDA from i386/trap.c
Not all of the code thate appeared to handle fpu traps was ever called!
Most of the changes just replace the include of machine/npx.h with x86/fpu.h
  (or remove it entirely).

Improve x86 tsc handling:

- Ditch the cross-CPU calibration stuff. It didn't work properly, and it's
  near impossible to synchronize the CPUs in a running system, because bus
  traffic will interfere with any calibration attempt, messing up the
  timings.

- Only enable the TSC on CPUs where we are sure it does not drift. If we are
  On a known good CPU, give the TSC high timecounter quality, making it the
  default.

- When booting CPUs, detect TSC skew and account for it. Most Intel MP
  systems have synchronized counters, but that need not be true if the
  system has a complicated bus structure. As far as I know, AMD systems
  do not have synchronized TSCs and so we need to handle skew.

- While an AP is waiting to be set running, try and make the TSC drift by
  entering a reduced power state. If we detect drift, ensure that the TSC
  does not get a high timecounter quality. This should not happen and is
  only for safety.

- Make cpu_counter() stuff LKM safe.

Add support for kernel preeemption to the i386 and amd64 ports. Notes:

- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.

Don't unconditionally clear the direction flag. The ABI says it must always
be clear when making a function call, and 'cld' takes about 50 clock cyles
on the P4.

x86 changes for pcc and LKMs.

- Replace most inline assembly with proper functions. As a side effect
  this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
  smaller amount. Nearly all of the inlines did something slow, or something
  that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
  In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.
