- Defined an abstract NVRAM I/O API (bhnd_nvram_io), decoupling NVRAM/SPROM
parsing from the actual underlying NVRAM data provider (e.g. CFE firmware
devices).
- Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling
higher-level NVRAM operations (indexed lookup, data conversion, etc) from
the underlying NVRAM file format parsing/serialization.
- Implemented a new high-level bhnd_nvram_store API, providing indexed
variable lookup, pending write tracking, etc on top of an arbitrary
bhnd_nvram_data instance.
- Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store
API.
- Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM
variable values, including applying format-specific behavior when
converting to/from the NVRAM string representations.
- Dropped the now unnecessary bhnd_nvram driver, and moved the
broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom.
- Implemented a new nvram_map file format:
- Variable definitions are now defined separately from the SPROM
layout. This will also allow us to define CIS tuple NVRAM
mappings referencing the common NVRAM variable definitions.
- Variables can now be defined within arbitrary named groups.
- Textual descriptions and help information can be defined inline
for both variables and variable groups.
- Implemented a new, compact encoding of SPROM image layout
offsets.
- Source-level (but not build system) support for building the NVRAM file
format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a
userspace library.
The new compact SPROM image layout encoding is loosely modeled on Apple
dyld compressed LINKEDIT symbol binding opcodes; it provides a compact
state-machine encoding of the mapping between NVRAM variables and the SPROM
image offset, mask, and shift instructions necessary to decode or encode
the SPROM variable data.
The compact encoding reduces the size of the generated SPROM layout data
from roughly 60KB to 3KB. The sequential nature SPROM layout opcode tables
also simplify iteration of the SPROM variables, as it's no longer
neccessary to iterate the full NVRAM variable definition table, but
instead simply scan the SPROM revision's layout opcode table.

Add missing fields ('sr' and 'mc_tls') to 'struct sigcontext'.
The kernel doesn't use 'struct sigcontext' but instead uses 'ucontext_t'
which includes 'mcontext_t' in 'struct sigframe' to build the signal frame.
As a result, this change is not an ABI change but simply making
'struct sigcontext' correct. Note that 'struct sigcontext' is only used
for "Traditional BSD style" signal handlers.
While here, rename the 'xxx' field to '__spare__' to match 'mcontext_t'.

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.

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.

Adds support for probing and initializing bhndb(4) bridge state using
the bhnd_erom API, ensuring that full bridge configuration is available
*prior* to actually attaching and enumerating the bhnd(4) child device,
allowing us to safely allocate bus-level agent/device resources during
bhnd(4) bus enumeration.
- Add a bhnd_erom_probe() method usable by bhndb(4). This is an analogue
to the existing bhnd_erom_probe_static() method, and allows the bhndb
bridge to discover the best available erom parser class prior to newbus
probing of its children.
- Add support for supplying identification hints when probing erom
devices. This is required on early EXTIF-only chipsets, where chip
identification registers are not available.
- Migrate bhndb over to the new bhnd_erom API, using bhnd_core_info
records rather than bridged bhnd(4) device_t references to determine
the bridged chipsets' capability/bridge configuration.
- The bhndb parent (e.g. if_bwn) is now required to supply a hardware
priority table to the bridge. The default table is currently sufficient
for our supported devices.
- Drop the two-pass attach approach we used for compatibility with bhndb(4) in
the bhnd(4) bus drivers, and instead perform bus enumeration immediately,
and allocate bridged per-child bus-level resources during that enumeration.

This defines a new bhnd_erom_if API, providing a common interface to device
enumeration on siba(4) and bcma(4) devices, for use both in the bhndb bridge
and SoC early boot contexts, and migrates mips/broadcom over to the new API.
This also replaces the previous adhoc device enumeration support implemented
for mips/broadcom.
Migration of bhndb to the new API will be implemented in a follow-up commit.
- Defined new bhnd_erom_if interface for bhnd(4) device enumeration, along
with bcma(4) and siba(4)-specific implementations.
- Fixed a minor bug in bhndb that logged an error when we attempted to map the
full siba(4) bus space (18000000-17FFFFFF) in the siba EROM parser.
- Reverted use of the resource's start address as the ChipCommon enum_addr in
bhnd_read_chipid(). When called from bhndb, this address is found within the
host address space, resulting in an invalid bridged enum_addr.
- Added support for falling back on standard bus_activate_resource() in
bhnd_bus_generic_activate_resource(), enabling allocation of the bhnd_erom's
bhnd_resource directly from a nexus-attached bhnd(4) device.
- Removed BHND_BUS_GET_CORE_TABLE(); it has been replaced by the erom API.
- Added support for statically initializing bhnd_erom instances, for use prior
to malloc availability. The statically allocated buffer size is verified both
at runtime, and via a compile-time assertion (see BHND_EROM_STATIC_BYTES).
- bhnd_erom classes are registered within a module via a linker set, allowing
mips/broadcom to probe available EROM parser instances without creating a
strong reference to bcma/siba-specific symbols.
- Migrated mips/broadcom to bhnd_erom_if, replacing the previous MIPS-specific
device enumeration implementation.

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.
