6775dfdf54 powerpc/powernv: Add OPAL flash device driver
Firmware needed by petitboot, for example, GPU firmware, can be installed to
a partition in the flash filesystem.  This driver exposes the full flash
given by the device tree, letting the user manage firmware, etc, from
FreeBSD.

To use the partitions provided by the flash module, the fdt_slicer module is
needed, but the module isn't needed for raw access, so there's no direct
dependency link in here.

dac618a648 powerpc/powernv: Add asynchronous token management for powernv
The OPAL firmware only supports a finite number of in-flight asynchronous
operations.  Rather than have each subsystem try to manage its own, use a
central management service to hand out tokens.

More work can be done to improve asynchronous behavior, such as funneling
things through a future OPAL heartbeat handler, but capabilities will be
added as needed.

Augment the existing consumers (i2c and sensors) to use this new API.

e8643b01e6 Modularize xz.
Embedded lzma decompression library becomes a module usable by other
consumers, in addition to geom_uzip.

Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
  with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
  initialization on its own.

xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.

The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

440f1cf75c Quick fix for building LINT on i386. A fix is needed on all arches and
this one should also work on amd64 and sparc64.

LINT was broken in r312910 with the removal of pc98 support, by changing
the pathname in UKBD_DFLT_KEYBAP from a removed pc98 file to a nonexistent
file.

There are many bugs nearby.  Some are:
- the error is not properly detected and handled by make(1), because
  kbdcontrol(8) exits with status 0 after failing to find the keymap file
- UKBD_DFLT_KEYBAP is supposed to be MI, and is in MI NOTES to try enforce
  this, but 5 out of 8 arches don't support it
- LINT seems to have been broken by this in only 7 out of 8 arches.  mips
  breaks test coverage instead, by killing this option in its MD NOTES.
  arm kills ukbd but that is not enough to configure an unsupported option
  used only by ukbd.

d09131e044 Connect the restored dumb and sc terminal emulators to the kernel build.
Add or fix options to control static and dynamic configuration.  Keep
the default of scteken, but default to statically configuring all available
emulators (now 3 instead of 1).

The dumb emulator is almost usable.  libedit and libreadline handle
dumb terminals perfectly for at least shell history.  less(1) works
as well as possible except on exit.  But curses programs make messes.
The dumb emulator has strange color support, with 2 dumb colors for
normal output but fancy colorization for the cursor, mouse pointer and
(with a non-dumb initial emulator) for low-level console output.

Using the sc emulator instead of the default of scteken fixes at least
the following bugs:
- NUL is a printing character in cons25 but not in teken
- teken doesn't support fixed colors for "reverse" video.
- The best versions of sc are about 10 times faster than scteken (for
  printing to the frame buffer).  This version is only about 5 times
  faster.

Fix configuration features:
- make SC_DFLT_TERM (for setting the initial emulator) a normal option.

Add configuration features:
- negative options SC_NO_TERM_* for omitting emulators in the static config.
  Modules for emulators might work, but I don't know of any
- vidcontrol -e shows the available emulators
- vidcontrol -E <emulator> sets the active emulator.

61ebc359ca Move scterm_teken.c from 6 MD files lists to the MI files list so that it
is easier to configure.  It is MI, unlike some of the other syscons files
already in the MI list.

Move scvtb.c similarly.  It is needed whenever sc is configured, and is
more MI than most of the files already in the MI list.

This only changes the combined list for arm64 and mips.  These arches
already cannot build sc or even NOTES.

The XIVE (External Interrupt Virtualization Engine) is a new interrupt
controller present in IBM's POWER9 processor.  It's a very powerful,
very complex device using queues and shared memory to improve interrupt
dispatch performance in a virtualized environment.

This yields a ~10% performance improvment over the XICS emulation mode,
measured in both buildworld, and 'dd' from nvme to /dev/null.

Currently, this only supports native access.

9a52756044 i386: Merge PAE and non-PAE pmaps into same kernel.
Effectively all i386 kernels now have two pmaps compiled in: one
managing PAE pagetables, and another non-PAE. The implementation is
selected at cold time depending on the CPU features. The vm_paddr_t is
always 64bit now. As result, nx bit can be used on all capable CPUs.

Option PAE only affects the bus_addr_t: it is still 32bit for non-PAE
configs, for drivers compatibility. Kernel layout, esp. max kernel
address, low memory PDEs and max user address (same as trampoline
start) are now same for PAE and for non-PAE regardless of the type of
page tables used.

Non-PAE kernel (when using PAE pagetables) can handle physical memory
up to 24G now, larger memory requires re-tuning the KVA consumers and
instead the code caps the maximum at 24G. Unfortunately, a lot of
drivers do not use busdma(9) properly so by default even 4G barrier is
not easy. There are two tunables added: hw.above4g_allow and
hw.above24g_allow, the first one is kept enabled for now to evaluate
the status on HEAD, second is only for dev use.

i386 now creates three freelists if there is any memory above 4G, to
allow proper bounce pages allocation. Also, VM_KMEM_SIZE_SCALE changed
from 3 to 1.

The PAE_TABLES kernel config option is retired.

756a541279 Allocate pager bufs from UMA instead of 80-ish mutex protected linked list.
o In vm_pager_bufferinit() create pbuf_zone and start accounting on how many
  pbufs are we going to have set.
  In various subsystems that are going to utilize pbufs create private zones
  via call to pbuf_zsecond_create(). The latter calls uma_zsecond_create(),
  and sets a limit on created zone. After startup preallocate pbufs according
  to requirements of all pbuf zones.

  Subsystems that used to have a private limit with old allocator now have
  private pbuf zones: md(4), fusefs, NFS client, smbfs, VFS cluster, FFS,
  swap, vnode pager.

  The following subsystems use shared pbuf zone: cam(4), nvme(4), physio(9),
  aio(4). They should have their private limits, but changing that is out of
  scope of this commit.

o Fetch tunable value of kern.nswbuf from init_param2() and while here move
  NSWBUF_MIN to opt_param.h and eliminate opt_swap.h, that was holding only
  this option.
  Default values aren't touched by this commit, but they probably should be
  reviewed wrt to modern hardware.

This change removes a tight bottleneck from sendfile(2) operation, that
uses pbufs in vnode pager. Other pagers also would benefit from faster
allocation.

b3c0d957a2 Add support for the Clang Coverage Sanitizer in the kernel (KCOV).
When building with KCOV enabled the compiler will insert function calls
to probes allowing us to trace the execution of the kernel from userspace.
These probes are on function entry (trace-pc) and on comparison operations
(trace-cmp).

Userspace can enable the use of these probes on a single kernel thread with
an ioctl interface. It can allocate space for the probe with KIOSETBUFSIZE,
then mmap the allocated buffer and enable tracing with KIOENABLE, with the
trace mode being passed in as the int argument. When complete KIODISABLE
is used to disable tracing.

The first item in the buffer is the number of trace event that have
happened. Userspace can write 0 to this to reset the tracing, and is
expected to do so on first use.

The format of the buffer depends on the trace mode. When in PC tracing just
the return address of the probe is stored. Under comparison tracing the
comparison type, the two arguments, and the return address are traced. The
former method uses on entry per trace event, while the later uses 4. As
such they are incompatible so only a single mode may be enabled.

KCOV is expected to help fuzzing the kernel, and while in development has
already found a number of issues. It is required for the syzkaller system
call fuzzer [1]. Other kernel fuzzers could also make use of it, either
with the current interface, or by extending it with new modes.

A man page is currently being worked on and is expected to be committed
soon, however having the code in the kernel now is useful for other
developers to use.

35bc37b6b9 Limit git history searches in newvers.sh
newvers.sh takes upwards of 4-5 seconds to complete on trees checked
out from github, due to searching the entire history for non-existent
git-svn metadata. Similarly, if one does not check out notes, we
again search the entire history for notes. That makes newvers.sh very
slow for many github users.

To fix this in a fair way, limit the history search to the last 10K
commits: if you're more than 10K commits out of sync, then you've
forked the project, and our SVN rev is no longer very important to you.

Due to how git implements --grep in conjunction with -n, --grep has been
removed for performance reasons (git does not seem to limit its search
to the -n limit in this case, and takes just as long as it did with no
limit).
