69cab2d1bf Fix locking in bcm2835_audio driver

c1bc87b161 Generate an error if machine/armreg.h is included without sys/cdefs.h
machine/armreg.h requires access to the __ARM_ARCH macro, which is not
always properly defined (especially by gcc 4.2.1). We should include
sys/cdefs.h in order to get the definitions in machine/acle-compat.h,
which would properly define the __ARM_ARCH macro in these cases.

So, in cases where machine/armreg.h is included without _SYS_CDEFS_H_
being defined - generate an #error.

 * Check ARM_USE_MP_EXTENSIONS when building for ARMv7+, even if no SMP.
 * Use ARM_USE_MP_EXTENSIONS in pmap-v6.c to detect when to set PRRR_NS1.

d3bf5efc1f Fix device delete child function.
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

bd79708dbf In the TCP stack, the hhook(9) framework provides hooks for kernel modules
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.

Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.

This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.

Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

ba14258f32 if_cpsw overhaul:
- Fix RX and TX teardown:
  . TX teardown would not reclaim the abandoned descriptors;
  . Interrupt storms in RX teardown;
  . Fixed the acknowledge of the teardown completion interrupt.

- Remove temporary lists for the descriptors;

- Simplified the descriptor handling (less writes and reads from
  descriptors where possible);

- Better debug;

- Add support for the RX threshold interrupts:
  With interrupt moderation only, an RX overrun is likely to happen.  The
  RX threshold is set to trigger a non paced interrupt everytime your RX
  free buffers are under the minimum threshold, helping to prevent the rx
  overrun.

The NIC now survive when pushed over its limits (where previously it would
lock up in a few seconds).

uFW (600MHz SoC) can now forward up to 560Mb/s of UDP traffic (netmap
pkt-gen as source and sink).  TCP forwarding rate is over 350Mb/s.

No difference (other than CPU use) was seen on Beaglebone black (1GHz SoC)
for his fast ethernet.

fa878ec311 Make it possible to safely use TPIDRURW from userspace.
On amd64, arm64 and i386, we have the possibility to switch between TLS
areas in userspace. The nice thing about this is that it makes it easier
to do light-weight threading, if we ever feel like doing that. On armv6,
let's go into the same direction by making it possible to safely use the
TPIDRURW register, which is intended for this purpose.

Clean up the ARMv6 code to remove md_tp entirely. Simply add a dedicated
field to the PCB to hold the value of TPIDRURW across context switches,
like we do for any other register. As userspace currently uses the
read-only TPIDRURO register, simply ensure that we keep both values in
sync where possible. The system calls for modifying the read-only
register will simply write the intended value into both registers, so
that it lazily ends up in the PCB during the next context switch.

5e7b54b184 Add very preliminary support for CloudABI for ARMv6.
In order to make CloudABI work on ARMv6, start off by copying over the
sysvec for ARM64 and adjust it to use 32-bit registers. Also add code
for fetching arguments from the stack if needed, as there are fewer
register than on ARM64.

Also import the vDSO that is needed to invoke system calls. This vDSO
uses the intra procedure call register (ip) to store the system call
number. This is a bit simpler than what native FreeBSD does, as FreeBSD
uses r7, while preserving the original r7 into ip.

This sysvec seems to be complete enough to start CloudABI processes.
These processes are capable of linking in the vDSO and are therefore
capable of executing (most?) system calls successfully. Unfortunately,
the biggest show stopper is still that TLS is completely broken:

- The linker used by CloudABI, LLD, still has troubles with some of the
  relocations needed for TLS. See LLVM bug 30218 for more details.

- Whereas FreeBSD uses the tpidruro register for TLS, for CloudABI I
  want to make use of tpidrurw, so that userspace can modify the base
  address directly. This is needed for efficient emulation.
  Unfortunately, this register doesn't seem to be preserved across
  context switches yet.

6af45170c1 Chelsio T4/T5 VF driver.
The cxgbev/cxlv driver supports Virtual Function devices for Chelsio
T4 and T4 adapters.  The VF devices share most of their code with the
existing PF4 driver (cxgbe/cxl) and as such the VF device driver
currently depends on the PF4 driver.

Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf
PCI device driver that attaches to the VF device.  It then creates
child cxgbev/cxlv devices representing ports assigned to the VF.
By default, the PF driver assigns a single port to each VF.

t4vf_hw.c contains VF-specific routines from the shared code used to
fetch VF-specific parameters from the firmware.

t4_vf.c contains the VF-specific PCI device driver and includes its
own attach routine.

VF devices are required to use a different firmware request when
transmitting packets (which in turn requires a different CPL message
to encapsulate messages).  This alternate firmware request does not
permit chaining multiple packets in a single message, so each packet
results in a firmware request.  In addition, the different CPL message
requires more detailed information when enabling hardware checksums,
so parse_pkt() on VF devices must examine L2 and L3 headers for all
packets (not just TSO packets) for VF devices.  Finally, L2 checksums
on non-UDP/non-TCP packets do not work reliably (the firmware trashes
the IPv4 fragment field), so IPv4 checksums for such packets are
calculated in software.

Most of the other changes in the non-VF-specific code are to expose
various variables and functions private to the PF driver so that they
can be used by the VF driver.

Note that a limited subset of cxgbetool functions are supported on VF
devices including register dumps, scheduler classes, and clearing of
statistics.  In addition, TOE is not supported on VF devices, only for
the PF interfaces.

dbbaf04f1e Remove support for idle page zeroing.
Idle page zeroing has been disabled by default on all architectures since
r170816 and has some bugs that make it seemingly unusable. Specifically,
the idle-priority pagezero thread exacerbates contention for the free page
lock, and yields the CPU without releasing it in non-preemptive kernels. The
pagezero thread also does not behave correctly when superpage reservations
are enabled: its target is a function of v_free_count, which includes
reserved-but-free pages, but it is only able to zero pages belonging to the
physical memory allocator.
