Prepare move of ctm from base to a port (misc/ctm) by:
- Adding a note to UPDATING

- Adding a message printed to STDERR to the ctm program

This version is meant for release in FreeBSD-12.0 and should remain in
FreeBSD-12 over its life-time.

A follow-up commit will remove ctm from -CURRENT after the MFC to 12

FreeBSD — head/sys/compat/freebsd32 capabilities.conf Makefile, head/sys/kern makesyscalls.sh

Use the main capabilities.conf for freebsd32.

Allow the location of capabilities.conf to be configured.

Also allow a per-abi syscall prefix to be configured with the
abi_func_prefix syscalls.conf variable and check syscalls against
entries in capabilities.conf with and without the prefix amended.

Take advantage of these two features to allow use shared capabilities.conf
between the default syscall vector and the freebsd32 compatability
layer.  We've been inconsistent about keeping the two in sync as
evidenced by the bugs fixed in r340294.  This eliminates that problem
going forward.

For compatibility KPI functions like if_addr_rlock() that used to have

Embedding tracker into ifnet(9) or ifnet derived structures creates a non
reentrable function, that will fail miserably if called simultaneously from
two different contexts.
A thread private tracker will provide a single tracker that would allow to
call these functions safely. It doesn't allow nested call, but this is not

libnv used fcntl(fd, F_GETFL) to test whether fd is a valid file

Add accounting to per-domain UMA full bucket caches.

In particular, track the current size of the cache and maintain an
estimate of its working set size.  This will be used to decide how
much to shrink various caches when the kernel attempts to reclaim
pages.  As a secondary effect, it makes statistics aggregation (done
by, e.g., vmstat -z) cheaper since sysctl_vm_zone_stats() no longer
needs to iterate over lists of cached buckets.

FreeBSD — head/sys/kern subr_blist.c, head/sys/sys blist.h

Allow allocations across meta boundaries.

Remove restrictions that prevent allocation requests to cross the
boundary between two meta nodes.

Replace the bmu_avail field in meta nodes with a bitmap that identifies
which subtrees have some free memory, and iterate over the nonempty
subtrees only in blst_meta_alloc.  If free memory is scarce, this should
make searching for it faster.

Put the code for handling the next-leaf allocation in a separate
function.  When taking blocks from the next leaf empties the leaf, be
sure to clear the appropriate bit in its parent, and so on, up to the
least-common ancestor of this leaf and the next.

Eliminate special terminator nodes, and rely instead on the fact that
there is a 0-bit at the end of the bitmask at the root of the tree that
will stop a meta_alloc search, or a next-leaf search, before the search
falls off the end of the tree. Make sure that the tree is big enough to
have space for that 0-bit.

Eliminate special all-free indicators.  Lazy initialization of subtrees
stands in the way of having an allocation span a meta-node boundary, so
a subtree of all free blocks is not treated specially.  Subtrees of
all-allocated blocks are still recognized by looking at the bitmask at

FreeBSD — head/sys/riscv/include riscvreg.h cpufunc.h

RISC-V: Add macros for reading performance counter CSRs.

The RISC-V spec defines several performance counter CSRs such as: cycle,
time, instret, hpmcounter(3...31).  They are defined to be 64-bits wide
on all RISC-V architectures.  On RV64 and RV128 they can be read from a
single CSR.  On RV32, additional CSRs (given the suffix "h") are present
which contain the upper 32 bits of these counters, and must be read as
well.  (See section 2.8 in the User ISA Spec for full details.)

This change adds macros for reading these values safely on any RISC-V
ISA length.  Obviously we aren't supporting anything other than RV64
at the moment, but this ensures we won't need to change how we read
these values if we ever do.

Add dynamic_kenv assertion to init_static_kenv

Both to formally document the requirement that this not be called after the
dynamic kenv is setup, and to perhaps help static analyzers figure out
what's going on. While calling init_static_kenv this late isn't fatal, there
are some caveats that the caller should be aware of:

- Late calls are effectively a no-op, as far as default FreeBSD is
concerned, as everything will switch to searching the dynamic kenv once it's

- Each of the kern_getenv calls will leak memory, as it's assumed that
these are searching static environment and allocations will not be made.

As such, this usage is not sensible and should be detected.

MFC r340302:

Fix freebsd32 mknod(at).

As dev_t is now a 64-bit integer, it requires special handling as a
system call argument.  64-bit arguments are split between two 64-bit
integers due to the way arguments are promoted to allow reuse of most
system call implementations.  They must be reassembled before use.
Further, 64-bit arguments at an odd offset (counting from zero) are
padded and slid to the next slot on powerpc and mips.  Fix the
non-COMPAT11 system call by adding a freebsd32_mknodat() and
appropriately padded declerations.

The COMPAT11 system calls are fully compatible with the 64-bit
implementations so remove the freebsd32_ versions.

Use uint32_t consistently as the type of the old dev_t.  This matches
the old definition.
