The lwp argument to fpu_save was added by chuq in revision 1.14 of

correct lwp to pass because we are in the middle of executing a
kernel-emulated fp instruction, so curlwp must own the fpu state, and
we are trying to write the fp registers to memory so we can adjust
them there when ctc1 would fail.

Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c

While at it, separate the source function tracking so that the interrupt
paths are truly independant.

Use weak symbol exporting to provision for future PVHVM co-existence
of both files, but with independant paths. Introduce assembler code
such that in a unified scenario, native interrupts get first priority
in spllower(), followed by XEN event callbacks. IPL management and
semantics are unchanged - native handlers and xen callbacks are
expected to maintain their ipl related semantics.

In summary, after this commit, native and XEN now have completely
unrelated interrupt handling mechanisms, including
intr_establish_xname() and assembler stubs and intr handler
management.

Note threadpool(9).

(thorpej)

Add threadpool(9), an abstraction that provides shared pools of kernel
threads running at specific priorities, with support for unbound pools
and per-cpu pools.

Written by riastradh@, and based on the May 2014 draft, with a few changes
by me:
- Working on the assumption that a relative few priorities will actually
  be used, reduce the memory footprint by using linked lists, rather than
  2 large (and mostly empty) tables.  The performance impact is essentially
  nil, since these lists are consulted only when pools are created (and
  destroyed, for DIAGNOSTIC checks), and the lists will have at most 225
  entries.
- Make threadpool job object, which the caller must allocate storage for,
  really opaque.
- Use typedefs for the threadpool types, to reduce the verbosity of the
  API somewhat.
- Fix a bunch of pool / worker thread / job object lifecycle bugs.

Also include an ATF unit test, written by me, that exercises the basics
of the API by loading a kernel module that exposes several sysctls that
allow the ATF test script to create and destroy threadpools, schedule a
basic job, and verify that it ran.

And thus NetBSD 8.99.29 has arrived.

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.

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.

In the end, disable the supposed architectural SpectreV2 mitigation on
AMD f12h and f16h. The SDMs of these CPUs haven't been updated since, and
we shouldn't assume the position of the bits, we just can't know where
they are.

Initially I included f12h and f16h because f10h is actually documented
to have a bit to disable the indirect branch predictor, and there were
patches available in SuSE and CentOS that were treating f10h/f12h/f16h
all the same. Knowing that SuSE has ties with AMD, it seemed safe to
assume that these patches were correct and that f12h and f16h could
indeed be treated the same way as f10h.

But these patches have now disappeared, and the main Linux branch
doesn't have them, without clear explanation. Therefore, I prefer to
roll-back.

Add AMD_SSB_NO, so that we explicitly say than an AMD CPU is not affected

This change modifies the mainbus(4) entry point for all x86 sub-archs
in the following way:

i) It provides a unified entry point in
  x86/x86/mainbus.c:mainbus_attach()
ii) It carves out the preliminary bus attachment sequence that is
  common to all sub-archs into
  x86/x86/mainbus.c: x86_cpubus_attach()
iii) It consolidates the remaining pathways as internal callee
  functions so that these may be called piecemeal if required. A
  special usecase of this is XEN PVHVM which may need to call the
  native configure path, the xen configure path, or both.
iv) It moves the driver private data structures from
  i386/i386_mainbus.c to an x86/ level one. This allows for other
  sub-arch's to do similar, if needed. (They do not at the moment).
v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
  'acpi0 at hypervisorbus'. This serves two purposes:
  a) To demonstrate the possibility of dynamic configuration tree
      traversal ordering changes.
  b) To allow for the common acpi_check(self, "acpibus") call in
  x86/mainbus.c to not barf when it is called from the dom0 attach
  path. We allow for the acpi0 device to be a child of mainbus with
  the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
  without actually probing further in the code. This path will later
  be pursued in a PVHVM boot codepath.

There should be no operative changes with this change. If there are,
please complain loudly.
