77e2eaf5b8 Fix build after r260234 by converting ddi_get_lbolt64() from inline into
a macro.  Otherwise compiler complains that hz variable used there either
undefined or defined twice, thanks to header mess caused by compat shims.

dcd08302e5 Retire machine/fdt.h as a header used by MI code, as its function is now
obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
  (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
  non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
  requests to its parent (nexus). This allows x86 FDT devices to allocate
  both memory and IO requests and removes the last notionally MI use of
  fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
  FDT_MAP_IRQ and FDT_INTR_MAX have been removed.

51dbd04609 Convert from using fdt_immr style to arm_devmap_add_entry() to make
static device mappings.

This SoC relied heavily on the fact that all devices were static-mapped
at a fixed address, and it (rather bogusly) used bus_space read and write
calls passing hard-coded virtual addresses instead of proper bus handles,
relying on the fact that the virtual addresses of the mappings were known
at compile time, and relying on the implementation details of arm
bus_space never changing.  All such usage was replaced with calls to
bus_space_map() to obtain a proper bus handle for the read/write calls.

This required adjusting some of the #define values that map out hardware
registers, and some of them were renamed in the process to make it clear
which were defining absolute physical addresses and which were defining
offsets.  (The ones that just define offsets don't appear to be referenced
and probably serve no value other than perhaps documentation.)

5bfc7db451 gcc: Add support for Apple's Block extension
Block objects [1] are a C-level syntactic and runtime feature. They
are similar to standard C functions, but in addition to executable
code they may also contain variable bindings to automatic (stack)
or managed (heap) memory. A block can therefore maintain a set of
state (data) that it can use to impact behavior when executed.

This port is based on Apple's GCC 5646 with some bugfixes from
Apple GCC 5666.3. It has some small differences with the support
in clang, which remains the recommended compiler.

Perhaps the most notable difference is that in GCC that __block
is not actually a keyword, but a macro. There will be workaround
for this issue in a near future. Other issues can be consulted in
the clang documentation [2]

For better compatiblity with Apple's GCC and llvm-gcc some related
fixes and features from Apple have been included. Support for the
non-standard nested functions in GCC is now off by default.

No effort was made to update the ObjC support since FreeBSD doesn't
carry ObjC in the base system, but some of the code crept in and
was more difficult to remove than to adjust.

093b9154fd Allow bsdinstall to use WPA-Enterprise networks when installing. This
only allows basic username/password config, and does not provide the
ability to set any of the other WPA options.  Regardless, this is
generally sufficient to associate.

Perhaps in the future this could allow full configuring (e.g. being able
to set "anonymous identity", and perhaps some of the more obscure WPA
options), though perhaps that will better belong in bsdconfig when that
grows wlan config ability.

c809a67a72 Replace locks added in r260229 to protect sequence counters with atomics.
New algorithm does not create additional lock congestion, while some races
it includes should not be a problem.  Those races may keep requests in DRC
cache for some more time by returning ACK position smaller then actual,
but it still should be able to drop thems when proper ACK finally read.

Races of the original algorithm based on TCP seq number were worse because
they happened when reply sequence number were recorded. After that even
correctly read ACKs could not clean DRC sometimes.

0a9ae358fd Fix a bug in the HPET emulation where a timer interrupt could be lost when the
guest disables the HPET.

The HPET timer interrupt is triggered from the callout handler associated with
the timer. It is possible for the callout handler to be delayed before it gets
a chance to execute. If the guest disables the HPET during this window then the
handler never gets a chance to execute and the timer interrupt is lost.

This is now fixed by injecting a timer interrupt into the guest if the callout
time is detected to be in the past when the HPET is disabled.

d473bac729 Rework NFS Duplicate Request Cache cleanup logic.
- Introduce additional hash to group requests by hash of sockref.  This
allows to process TCP acknowledgements without looping though all the cache,
and as result allows to do it every time.
 - Indroduce additional callbacks to notify application layer about sockets
disconnection.  Without this last few requests processed just before socket
disconnection never processed their ACKs and stuck in cache for many hours.
 - Implement transport-specific method for tracking reply acknowledgements.
New implementation does not cross multiple stack layers to get the data and
does not have race conditions that previously made some requests stuck
in cache.  This could be done more efficiently at sockbuf layer, but that
would broke some KBIs, while I don't know other consumers for it aside NFS.
 - Instead of traversing all DRC twice per request, run cleaning only once
per request, and except in some conditions traverse only single hash slot
at a time.

Together this limits NFS DRC growth only to situations of real connectivity
problems.  If network is working well, and so all replies are acknowledged,
cache remains almost empty even after hours of heavy load.  Without this
change on the same test cache was growing to many thousand requests even
with perfectly working local network.

As another result this reduces CPU time spent on the DRC handling during
SPEC NFS benchmark from about 10% to 0.5%.
