xen/x86: Get the right intrframe pointer in ddb ipi.

This was broken with the transition from evtchn_set_handler to
intr_establish_xname in 2017, remained broken with the transition
from intr_establish_xname to xen_intr_establish_xname in 2018, and
still remained broken when xen_intr_establish_xname was changed back
to evtchn_set_handler in 2020.

The mechanism is grody -- instead of a secret second argument to the
interrupt handler, the intrframe pointer should be replaced by a
struct cpu_info member that is saved and restored by the interrupt
handler calling logic.  But we should make sure the replacement
actually works first -- which is not trivial in part because the
users are hidden behind sketchy function pointer casts.

With any luck, this will make `mach cpu N' work in ddb on Xen.

Change event_set_handler() to take the target CPU parameter. If ci is NULL,
  event_set_handler() will choose the CPU and bind the event.
  If ci is not NULL the caller is responsible for binding the event.
Use a IPI xcall to register the handlers if needed.
pull in a hack from x86 to force pirq handlers to be mpsafe if registered at
a level != IPL_VM. This is for the com at isa interrupt handler, which
registers at IPL_HIGH and has to way to tell it's mpsafe (taking
KERNEL_LOCK at IPL_HIGH causes deadlocks on MP systems).

By default, events are bound to CPU 0 (exept for IPIs and VTIMERs which
are bound to a different CPU at creation time).
Recent MI changes caused the scheduler to choose a different CPU when
probing and attaching xennet devices (I guess it's the xenbus thread which
runs on a different CPU). This cause the callback to be called on a different
CPU than the one expected by the kernel, and the event is ignored.
It is handled when the clock causes the callback to be called on the right
CPU, which is why xennet still run, but slowly.

Change event_set_handler() to do a EVTCHNOP_bind_vcpu if requested to,
and make sure we don't do it for IPIs and VIRQs (for theses, the op fails).

Fix false sharing problems with cpu_info.  Identified with tprof(8).
This was a very nice win in my tests on a 48 CPU box.

- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
  the IPI bitmask and ci_want_resched.

Bifurcate the interrupt establish functions between XEN and non-XEN

Thus intr_establish_xname() becomes xen_intr_establish_xname() etc.

One consequence of this is that dom0 devices expect the native
function calls to be available and we thus provide weak aliasing for
dom0 builds to succeed. XEN and non-XEN devices are distinguished by
the PIC they are established on. XEN interrupts are exclusively
established on xen_pic, while dom0 interrupts are established on
natively available PICs.

This allows us an orthogonal path to xen device management (eg:
xenstore events) in XENPVHVM, without having to worry about unifying
the vector entry paths, etc., which is quite challenging.

add support for kern.intr.list aka intrctl(8) 'list' for xen

event_set_handler() and pirq_establish() now have extra intrname
parameter; shared intr_create_intrid() is used to provide the value

xen drivers were changed to pass the specific driver instance
name as the xname, e.g.  'vcpu0 clock' instead just 'clock', or
'xencons0' instead of 'xencons'

associated evcnt is now changed to use intrname - this matches native x86

Remove support for 'external' floating point units and the MS-DOS
  compatible method of handling floating point exceptions.
Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
  is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
  to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
  cpu_configure(), this enables FP emulation for a 486SX.
  (for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
  save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.
The i386 XEN kernels build, but I'm not sure where they set cr0, and
  it might have got lost!

This reduces the amount of MD code enormously, and makes it easier

Apply patch proposed in PR port-xen/45975 (this does not solve the exact
problem reported here but is part of the solution):
xen_kpm_sync() is not working as expected,
leading to races between CPUs.
1 the check (xpq_cpu != &x86_curcpu) is always false because we
  have different x86_curcpu symbols with different addresses in the kernel.
  Fortunably, all addresses dissaemble to the same code.
  Because of this we always use the code intended for bootstrap, which doesn't
  use cross-calls or lock.

2 once 1 above is fixed, xen_kpm_sync() will use xcalls to sync other CPUs,
  which cause it to sleep and pmap.c doesn't like that. It triggers this
  KASSERT() in pmap_unmap_ptes():
  KASSERT(pmap->pm_ncsw == curlwp->l_ncsw);
3 pmap->pm_cpus is not safe for the purpose of xen_kpm_sync(), which
  needs to know on which CPU a pmap is loaded *now*:
  pmap->pm_cpus is cleared before cpu_load_pmap() is called to switch
  to a new pmap, leaving a window where a pmap is still in a CPU's
  ci_kpm_pdir but not in pm_cpus. As a virtual CPU may be preempted
  by the hypervisor at any time, it can be large enough to let another
  CPU free the PTP and reuse it as a normal page.

To fix 2), avoid cross-calls and IPIs completely, and instead
use a mutex to update all CPU's ci_kpm_pdir from the local CPU.
It's safe because we just need to update the table page, a tlbflush IPI will
happen later. As a side effect, we don't need a different code for bootstrap,
fixing 1). The mutex added to struct cpu needs a small headers reorganisation.

to fix 3), introduce a pm_xen_ptp_cpus which is updated from
cpu_pmap_load(), whith the ci_kpm_mtx mutex held. Checking it with
ci_kpm_mtx held will avoid overwriting the wrong pmap's ci_kpm_pdir.

While there I removed the unused pmap_is_active() function;
and added some more details to DIAGNOSTIC panics.

to the panic format string when the assertion triggers, with optional
arguments.

Fix call sites to reflect the new definition.
