cff4748967 hyperv: Register Hyper-V timer early enough for TSC freq calibration
The i8254 simulation in Hyper-V is kinda broken and is not available
in Generation 2 Hyper-V VMs, so Hyper-V timer must be registered early
enough so that it can be used to do the TSC freq calibration.

This fixes the notorious warning like this:
calcru: runtime went backwards from 50 usec to 25 usec for pid 0 (kernel)

case 'g' makes use of value n, which is initialized for case 'b'
and passe through to case 'g'. If case 'g' is called directly
value 'n' is not initialized.

Avoid the issue by initializing n before entering the switch.

e935e22d08 Correct error messages in recently added test.
The large read test uses an empty file created via mkstemp() rather than
/dev/null as character devices are subject to two different clamping
sysctls.  However, I forgot to update some of the error messages after
changing to mkstemp() that were still referring to /dev/null.

34d932442d Sync in the latest CloudABI system call definitions.
Some time ago I made a change to merge together the memory scope
definitions used by mmap (MAP_{PRIVATE,SHARED}) and lock objects
(PTHREAD_PROCESS_{PRIVATE,SHARED}). Though that sounded pretty smart
back then, it's backfiring. In the case of mmap it's used with other
flags in a bitmask, but for locking it's an enumeration. As our plan is
to automatically generate bindings for other languages, that looks a bit
sloppy.

Change all of the locking functions to use separate flags instead.

b4f65d818d Rework handling of thread sleeps before timers are working.
Previously, calls to *sleep() and cv_*wait*() immediately returned during
early boot.  Instead, permit threads that request a sleep without a
timeout to sleep as wakeup() works during early boot.  Sleeps with
timeouts are harder to emulate without working timers, so just punt and
panic explicitly if any thread tries to use those before timers are
working.  Any threads that depend on timeouts should either wait until
SI_SUB_KICK_SCHEDULER to start or they should use DELAY() until timers
are available.

Until APs are started earlier this should be a no-op as other kthreads
shouldn't get a chance to start running until after timers are working
regardless of when they were created.

f2f9534e13 Fix number of the enabled VFs in VNIC
nic->num_vf_en is set based on the number of the enabled LMACs.
This number should not be overwritten later by any routine.
Instead it should fail PCI_IOV_ADD_VF() so that available VFs
with the corresponding LMACs will attach whereas other, disabled
VFs will fail with the proper error code.
Error signaling (due to improper number of VFs requested) is also moved
from PCI_IOV_INIT() to PCI_IOV_ADD_VF().

This will be reworked when multiple queue sets are enabled but for
now this is the correct behavior of the driver.

017de7e4a5 Fix MAC address configuration for VNIC
The FDT description is as follows:
- phy-handle, reg, qlm-mode, mac-address are under nodes in bgx0/1 node
- phy nodes (pointed by phy-handle) are under MDIO even though they may
  not be connected through to MDIO. In those nodes they do not contain
  MAC address or etc.

This commit changes parsing of the FDT nodes for BGX so that it can
obtain correct MAC address for a given PHY.

- Avoid memory leak when nicvf_tx_mbuf_locked() fails
- Introduce nicvf_xmit_locked() routine that uses drbr_peek(),

  This gives more clear and efficient design as well as
  prevents from dropping mbufs that where not sent due to temporary
  lack of descriptors.
- Add missing ETHER_BPF_MTAP() hook

b45ea0fe80 Add support for 4 level pagetables. The userland address space has been
increased to 256TiB. The kernel address space can also be increased to be
the same size, but this will be performed in a later change.

To help work with an extra level of page tables two new functions have
been added, one to file the lowest level table entry, and one to find the
block/page level. Both of these find the entry for a given pmap and virtual
address.

This has been tested with a combination of buildworld, stress2 tests, and
by using sort to consume a large amount of memory by sorting /dev/zero. No
new issues are known to be present from this change.
