The checkpoints are another way of keeping the state of ZFS.
During the rewind, the pool has to be exported.
This makes checkpoints unusable when using ZFS as root.
Add the option to rewind the ZFS checkpoint at the boot time.
If checkpoint exists, a new option for rewinding a checkpoint will appear in
the bootloader menu.
We fully support boot environments.
If the rewind option is selected, the boot loader will show a list of
boot environments that existed before the checkpoint.

Since cubic calculates cwnd based on absolute
time, retaining RFC3465 (ABC) once-per-window updates
can lead to dramatic changes of cwnd in the convex
region. Updating cwnd for each incoming ack minimizes
this delta, preventing unintentional line-rate bursts.

After r340674, the "continue" would restart the loop without having

of simply ignoring all control messages on such sockets, since we
currently only implement handling for AF_UNIX-specific messages.

Recent versions of UEFI have moved local APIC timer initialization into
the early SEC phase which runs out of ROM, prior to self-relocating
into RAM. This results in a hypervisor exit.
Currently bhyve prevents instruction emulation from segments that aren't
marked as "sysmem" aka guest RAM, with the vm_gpa_hold() routine failing.
However, there is no reason for this restriction: the hypervisor already
controls whether EPT mappings are marked as executable.
Fix by dropping the redundant check of sysmem.

This was discussed in arch@ a while ago. Most of the 16-bit drivers that it
relied on have been removed. There's only a few other drivers remaining that
support it, and those are very rare the days (even the once ubiquitious wi(1)
is now quite rare).
Indvidual drivers will be handled separately before pccard itself is removed.
Remove PC Card specific information. It's of little value these days and on
the way out after most of its drivers have been removed.
Use iwn instead of wi device.
This is a partial revert of r363210, since the "use_ext" argument added
by that commit is not actually useful.
This patch should not result in any semantics change.
Rather than coding an array size of [4] replace the number with
WME_NUM_AC.

This uses GCC toolchains instead of LLVM on architectures supported by
GCC. Currently this uses GCC 6 on aarch64, amd64, i386, and mips.
Although this does also try to use GCC 6 on powerpc, it is always
skipped for now since a powerpc-gcc6 package is not available and the
structure of make universe makes it hard to skip a subset of arches
for a target. This should be short-lived as freebsd-gcc9 does include
a powerpc-gcc9 package so powerpc should work once this switches to
GCC 9.

vm_object_madvise() is a no-op for unmanaged objects, but we should also
limit the scope of mappings on which pmap_remove() is called. In
particular, with the WIP largepage shm objects patch the kernel must
remove mappings of such objects along superpage boundaries, and without
this check Linux madvise(MADV_DONTNEED) could violate that requirement.
