82c088adf3 MFi386: revisions 220389 and 220392
- Mark getc() as inline, this has no effect on gcc but helps clang.
  - Move getc() body before xgetc() so gcc does not emit a warning about
    function having no body.

e253ede763 Add 2 new archsw interfaces:
1.  arch_loadaddr - used by platform code to adjust the address at which
    the object gets loaded. Implement PC98 using this new interface instead
    of using conditional compilation. For ELF objects the ELF header is
    passed as the data pointer. For raw files it's the filename. Note that
    ELF objects are first considered as raw files.
2.  arch_loadseg - used by platform code to keep track of actual segments,
    so that (instruction) caches can be flushed or translations can be
    created. Both the ELF header as well as the program header are passed
    to allow platform code to treat the kernel proper differently from any
    additional modules and to have all the relevant details of the loaded
    segment (e.g. protection).

ccc0d4f324 MFi386: the part of 219452
- bunch of variables are turned into uint8_t.
  - the setting and reading of "fmt" in load() is removed.

3edd099649 MFi386: revision 219186
This patch shrinks boot2 a little.

  o    It switches kname to be just a pointer instead of an array.
  o    It changes ioctl to unsigned from uint8_t.
  o    It changes the second keyhit limit to 3 seconds from 5.
  o    It removes bi_basemem/bi_extmem/bi_memsizes_valid setting.

In sys/boot/i386/boot2/boot2.c, change the type of the 'opts' variable
  from uint16_t back to uint32_t.  The actual option bitmasks (RB_* and
  RBX_*) assume at least a 32 bit variable.

0f23475721 When building world with clang, for gnu/lib/libobjc, sys/boot/i386/boot2
and sys/boot/pc98/boot2, do not simply assign 'gcc' to CC, since compile
flags are sometimes passed via this variable, for example during the
build32 stage on amd64.  This caused the 32-bit libobjc build on amd64
to fail.

Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

1aa8466f89 Reimplement the boot2 for pc98 completely.
It's based on the newest i386's one and has the advantage of:

 - ELF binary support.
 - UFS2 filesystem support.
 - Many FreeBSD slices support on a disk.

be7768ee54 - 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.
