This change was made to allow zstd(1) to be a dropin replacement for gzip(1) and
friends, allowing easy integration, in particular with newsyslog(8). At the
price of having a zstd(1) command which by default behaves differently than what
upstream default, confusing users.
newsyslog(8) has been adapted to now be more flexible in what it accepts as
compression program, so we can switch back zstd(1) to its default behaviour

Summary:
Some architectures (powerpc Book-E) have a vm_paddr_t larger than intptr_t.
Casting from the intptr_t to vm_paddr_t causes sign extension, leading to a
potentially invalid address.
This was seen when running X on a PowerPC P1022 machine, which mapped the
backing framebuffer at 0xc1800000. When mmap()d by X, this yielded an invalid
address of 0xffffffffc1800000, or, as the hardware would see it, 0xfc1800000.

causes foo and foo@@VER to be output to the .o file. This requires foo
to be weak since the linker handles foo@@VER as foo.
Using

causes just foo@@ver to be output and avoid the need for making foo
weak. It also reduces the constraint on how exactly a linker has to

The OBJS_DEPEND_GUESS mechanism was making vmx_genassym.o depend

on having vmx_genassym.o present to generate. Moving the headers
to DPSRCS is enough to resolve the issue as they will no longer
be implicit dependencies for all objects. Because of this we
need explicit OBJS_DEPEND_GUESS entries to ensure the headers

This patch add a count of outstanding issued write delegations to the

Recent DTS (from Linux 4.14) specify a compatible "allwinner,sun50i-h5-ccu"
for H5 SoC. Since we get the DTB from u-boot this wasn't noticed.
Add the compatible so later version of u-boot will not fail for us.
This is better than directly changing PCI configuration space of the
device because it makes the PCI bus aware of the configuration.
Also, the change allows to drop a bunch of code that duplicated
pci_enable_msi() functionality.
I wonder if it's possible to further simplify the code by using
pci_alloc_msi().
ivhd should attach after the root PCI bus and, thus, after the ACPI
Host-PCI bridge off which the bus hangs. This is because ivhd changes
PCI configuration of a PCI IOMMU device that is located on the root bus.
If the bus attaches after ivhd it clears the MSI portion of the
configuration. As a result IOMMU event interrupts would never be
delivered.
For regular ACPI devices the order is calculated as
ACPI_DEV_BASE_ORDER + level * 10
where level is a depth of the device in the ACPI namespace.
I expect the depth of the Host-PCI bridge to be two or three,
so ACPI_DEV_BASE_ORDER + 10 * 10 should be a sufficiently safe order
for ivhd.
This should fix the setup of the AMD-Vi event interrupt when vmm is
preloaded (as opposed to kldload-ed).
This ensures that we can receive further event interrupts.
See the description of the bits in the specification for
MMIO Offset 2020h IOMMU Status Register.
The bits are defined as set-by-hardware write-1-to-clear, same as all
the bits in the status register.

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.

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
