arm64 boot sequence. This will be a virtual address in the kernel space
after the kernel and any modules loaded by loader so we can use this to
find the size of the kernel + modules. We can then add on a level 2 page for
the module data and round up the size to be aligned to a level 2 page.
This allows more than 8 MiB of modules to be loaded by loader, e.g. zfs.ko
and opensolaris.ko.

Commit r326346 moved domain iterators from physical layer to vm_page one,
but it also removed translation of freelist to flind for
vm_page_alloc_freelist() call. Before it expects VM_FREELIST_ parameter,
but after it expect freelist index.
On small WiFi boxes with few megabytes of RAM, there is only one freelist
VM_FREELIST_LOWMEM (1) and there is no VM_FREELIST_DEFAULT(0) (see file
sys/mips/include/vmparam.h). It results in freelist 1 with flind 0.
At first, this commit renames flind to freelist in vm_page_alloc_freelist
to avoid misunderstanding about input parameters. Then on physical layer it
restores translation for correct handling of freelist parameter.

Previous to the switch from sys/boot to stand/ zfsboot (used for MBR) did
not support GELI. Now that it is compiled with GELI, it is running out of
space.
zfsldr (which loads zfsboot) was modified to load 256kb in r304321
The existing check of the GCC version number is not sufficient
This fixes the build on sparc64 in preparation for integrating ZSTD into
the kernel for ZFS and Crash Dumps.
The cloudabi32.ko kernel modules can only be loaded on AMD64 and ARM64
by kernels built with COMPAT_FREEBSD32. Even though COMPAT_FREEBSD32
does not support the execution of native FreeBSD executables, do add it
to GENERIC, to make cloudabi32.ko usable.
According to size(1), this makes the kernel image approximately 0.7%
larger.

We can't kldunload in the test head as Kyua interprets any output from
them. This would lead to syntax errors and skipping the entire file.
Move the kld commands into the test case bodies.

This allows one to override the environment for processes created with
dtrace -c. By default, the environment is inherited.
This support was originally merged from illumos in r249367 but was lost
when the commit was later reverted and then brought back piecemeal.

little early.

At present, only HD() device types are supported (both GPT and
MBR). CdRom and floppy devices aren't supported. ZFS isn't supported
because there's no way in the UEFI standard to specify a ZFS datastore.
Network devices aren't supported either.
Three forms of Unix path are accepted: /path/to/file (for a mounted
filesystem), //path/to/file (uses the EFI partition on the same disk
as /), and dev:/path/to/file (for unmounted filesystem). Two forms are
produced (the first and last).

Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).
The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.
This diff introduces opt-in bwn(4) support for bhnd(4) by providing:
- A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
bhnd(4) instead of siba_bwn(4).
- A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
probes at a higher priority than the siba_bwn(4) PCI driver.
- A set of compatibility shims that perform translation of bwn(4)'s
siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
is attached via a bhnd(4) bus parent. When bwn(4) is attached via
siba_bwn(4), all siba_bwn function calls are simply passed through to
their original implementations.
To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):
hw.bwn_pci.preferred="1"
if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"
bwn_v4_lp_ucode_load="YES"
To verify that bwn(4) is using bhnd(4), you can check dmesg:
bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0
... or devinfo(8):
pcib2
pci2
bwn_pci0
bhndb0
bhnd0
bwn0
...
bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently
supported by bwn(4), including:
- BCM4312
- BCM4318
- BCM4321
With minimal changes to the DMA code (not included in this commit), I was
also able to test support for newer BCMA devices by bringing up basic
working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets:
- BCM43224
- BCM43225

- Add missing call to device_delete_children() in bhndb_detach(), without
which we're left with stale child devices on module unload.
- Pass the parent PCI device to pci_release_msi(), not the bhndb_pci(4)
child.
