Some filesystems do not fill out certain optional vattr fields. To
ensure that they do not get copied out to userspace uninitialized, use
VATTR_NULL to provide default values.

Some new AMD systems provide a HPET MMIO region smaller than the 1KB
specified, and a correspondingly small number of timers. Handle this in
the HPET driver rather than requiring a 1KB window. This allows the
HPET driver to attach on such systems.

Makes it cheaper to compare rules when "keep_counters" is set.
This also sets up keeping them in a RB tree.

gradually reducing the scope of rules lock when changing the

Otherwise all anchors hash to the same value.
Note this can result in checksum mismatches between pfsynced hosts,
but it has to be sorted out as the previously computed checksum
would fail to indicate changed anchors.

Make sure both sides of a comparison are unsigned. As the values being
compared are size_t make the the value in the for loop size_t too.

On arm64 we can ask the hardware to perform cache operations from
userspace. These require read permission however when the memory is
unmapped the kernel will receive a write exception. Add a check to
see if the cause of the exception is from the cache and pass a memory
read fault type to the vm subsystem.

Provide libedit a special function making it always add a space after
the autocompleted command. The default one adds a slash if the word is
also a name of a directory in the current working directory, but this is
wrong for commands.

Use of stdatomic.h is undefined in C++, even the C++ 2020 standard does not
list stdatomic.h as a C library header supported by the language. More,
there are some subtle differences between the <atomic> C++ header, and
C11+ stdatomic.h provided features.
Nonetheless, it is a quality of the implementation aspect, so let mis-users
mis-use stdatomic.h as they want, by making a compat shim for _Bool.

In contrast to Linux it does not provide entries which can be readlinked
-- these are just regular files, not giving the expected outcome. That's
on top of procfs not being mounted by default to begin with.
