c22616ec0b - Initialize the vm86 structure to a known-good state. Specifically, always
set the %eflags used during a BIOS call via BTX to 0x202.  Previously
  the flags field was uninitialized garbage, and thus it was "random" if
  interrupts were enabled or not during BIOS calls.
- Use constants from <machine/psl.h> for fields in %eflags.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

18a60bb546 MFi386: revision 1.41
Slightly cleanup the 'bootdev' concept on x86 by changing the various
  macros to treat the 'slice' field as a real part of the bootdev instead
  of as hack that spans two other fields (adaptor (sic) and controller)
  that are not used in any modern FreeBSD boot code.

932d8c46a2 Extend struct devdesc with a unit field, called d_unit. Promote the
device (kind) specific unit field to the common field. This change
allows a future version of libefi to work without requiring anything
more than what is defined in struct devdesc and as such makes it
possible to compile said version of libefi for different platforms
without requiring that those platforms have identical derivatives
of struct devdesc.

5cae408f81 Don't unconditionally compile-in the bcache code. It's only used on
i386/amd64 and pc98. Remove useless calls to bcache_init() from the
ia64 and sparc64 loaders, as well as from the OFW common code.

8b7c03a7a4 - Add support to the loader for multiple consoles.
- Teach the i386 and pc98 loaders to honor multiple console requests from
  their respective boot2 binaries so that the same console(s) are used in
  both boot2 and the loader.
- Since the kernel doesn't support multiple consoles, whichever console is
  listed first is treated as the "primary" console and is passed to the
  kernel in the boot_howto flags.

05d0bf79ed Remove the last vestiges of the userconfig option. None of this actually
did anything, so this commit should be considered a NO-OP.

e581f644a4 Initiate deorbit burn of i386 a.out kld "support" in loader. Note that
this was quite broken, it never was updated for metadata support.
The a.out kld file support was never really used, as it wasn't necessary.
You could always load elf kld's, even in an a.out kernel.

d1bdfb40fd -ffreestanding is the word.
(also resort some CFLAGS such that the more "important" value are first so
they are easier to see)
