Add a new VCPU conf option, that allows userland to request VMEXITs after a
TPR change. This is supported on all Intel CPUs, and not-too-old AMD CPUs.

The reason for wanting this option is that certain OSes (like Win10 64bit)
manage interrupt priority in hardware via CR8 directly, and for these OSes,
the emulator may want to sync its internal TPR state on each change.

Add two new fields in cap.arch, to report the conf capabilities. Report TPR

which to test.

Fix another boot failure issue of NetBSD/zaurus 8.x and later.

It looks some cacheline alignment restriction so that zbsdmod.o in

between I-cache flush and jumping to the loaded kernel into the
same cacheline solves the issue.

1. All Makefiles that use ARM_APCS_FLAGS add -marm unconditionally and

  it from everywhere else.
2. gcc-8 now warns about thumb internetwork in APCS mode. This does not make
  sense because the documentation says that this flag does not make a

  So we just add it to silence the warnings.

Enable TEST_LWP_ENABLED in t_ptrace_wait*
The LWP events (created, exited) are now reliable in my local tests.
PR kern/51420
PR kern/51995

Remove the short-circuit lwp_exit() path from sigswitch()

sigswitch() can be called from exit1() through:

  ttywait()->ttysleep()-> cv_timedwait_sig()->sleepq_block()->issignal()->sigswitch()

lwp_exit() called for the last LWP triggers exit1() and this causes a panic.
The debugger related signals have short-circuit demise paths in
eventswitch() and other functions, before calling sigswitch().

This change restores the original behavior, but there is an open question
whether the kernel crash is a red herring of misbehavior of ttywait().
This should fix PR kern/54618 by David H. Gutteridge

Fix a race condition when handling concurrent LWP signals and add a test

Fix a race condition that caused PT_GET_SIGINFO to return incorrect
information when multiple signals were delivered concurrently
to different LWPs.  Add a regression test that verifies that when 50
threads concurrently use pthread_kill() on themselves, the debugger
receives all signals with correct information.

The kernel uses separate signal queues for each LWP.  However,
the signal context used to implement PT_GET_SIGINFO is stored in 'struct
proc' and therefore common to all LWPs in the process.  Previously,
this member was filled in kpsignal2(), i.e. when the signal was sent.

This meant that if another LWP managed to send another signal
concurrently, the data was overwritten before the process was stopped.

As a result, PT_GET_SIGINFO did not report the correct LWP and signal
(it could even report a different signal than wait()).  This can be
quite reliably reproduced with the number of 20 LWPs, however it can
also occur with 10.

This patch moves setting of signal context to issignal(), just before
the process is actually stopped.  The data is taken from per-LWP
or per-process signal queue.  The added test confirms that the debugger
correctly receives all signals, and PT_GET_SIGINFO reports both correct
LWP and signal number.

      NVMM_EVENT_INTERRUPT_HW -> NVMM_VCPU_EVENT_INTR
      NVMM_EVENT_EXCEPTION    -> NVMM_VCPU_EVENT_EXCP
  Delete NVMM_EVENT_INTERRUPT_SW, unused already.

- Slightly reorganize the MI/MD definitions, for internal clarity.

- Split NVMM_VCPU_EXIT_MSR in two: NVMM_VCPU_EXIT_{RD,WR}MSR. Also provide
  separate u.rdmsr and u.wrmsr fields. This is more consistent with the
  other exit reasons.

- Change the types of several variables:
      event.type                  enum -> u_int
      event.vector                uint64_t -> uint8_t
      exit.u.*msr.msr:            uint64_t -> uint32_t
      exit.u.io.type:            enum -> bool
      exit.u.io.seg:              int -> int8_t
      cap.arch.mxcsr_mask:        uint64_t -> uint32_t
      cap.arch.conf_cpuid_maxops: uint64_t -> uint32_t

- Delete NVMM_VCPU_EXIT_MWAIT_COND, it is AMD-only and confusing, and we
  already intercept 'monitor' so it is never armed.

- Introduce vmx_exit_insn() for NVMM-Intel, similar to svm_exit_insn().
  The 'npc' field wasn't getting filled properly during certain VMEXITs.

- Introduce nvmm_vcpu_configure(). Similar to nvmm_machine_configure(),
  but as its name indicates, the configuration is per-VCPU and not per-VM.
  Migrate and rename NVMM_MACH_CONF_X86_CPUID to NVMM_VCPU_CONF_CPUID.
  This becomes per-VCPU, which makes more sense than per-VM.

- Extend the NVMM_VCPU_CONF_CPUID conf to allow triggering VMEXITs on
  specific leaves. Until now we could only mask the leaves. An uint32_t
  is added in the structure:
uint32_t mask:1;
uint32_t exit:1;
uint32_t rsvd:30;
  The two first bits select the desired behavior on the leaf. Specifying
  zero on both resets the leaf to the default behavior. The new
  NVMM_VCPU_EXIT_CPUID exit reason is added.

PR install/54480: when upgrading a system and re-mounting the target /
with proper options, and the installed system does not use NAME= syntax
in fstab(5), use the device name we used to get here, instead of the
name from fstab, it might be different to what the real system calls the
device (compact flash root showing up as wd0 native, but sd? on the
card reader used for updating it right now).
This is an abuse of the upgrade functionality and in general pretty dangerous
when multiple devices are used in the upgraded fstab (e.g. separate /usr),
and it used to work more by accident with the old code.
However, it is a quite usefull way to upgrade tiny systems with compact flash
root, and it used to work - so support it properly (as far as we can).

Fix a race condition when handling concurrent LWP signals and add a test

Fix a race condition that caused PT_GET_SIGINFO to return incorrect
information when multiple signals were delivered concurrently
to different LWPs.  Add a regression test that verifies that when 50
threads concurrently use pthread_kill() on themselves, the debugger
receives all signals with correct information.

The kernel uses separate signal queues for each LWP.  However,
the signal context used to implement PT_GET_SIGINFO is stored in 'struct
proc' and therefore common to all LWPs in the process.  Previously,
this member was filled in kpsignal2(), i.e. when the signal was sent.
This meant that if another LWP managed to send another signal
concurrently, the data was overwritten before the process was stopped.

As a result, PT_GET_SIGINFO did not report the correct LWP and signal
(it could even report a different signal than wait()).  This can be
quite reliably reproduced with the number of 20 LWPs, however it can
also occur with 10.

This patch moves setting of signal context to issignal(), just before
the process is actually stopped.  The data is taken from per-LWP
or per-process signal queue.  The added test confirms that the debugger
correctly receives all signals, and PT_GET_SIGINFO reports both correct
LWP and signal number.
