a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)
to build the kernel. It doesn't affect the operation if gcc.

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:
 - in_cksum.[ch]:
   * use a generic C version instead of the assembly version in the !gcc
     case (ASM code breaks with the optimizations icc does)
     -> no bad checksums with an icc compiled kernel
     Help from:		andre, grehan, das
     Stolen from: 	alpha version via ppc version
     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

4d450ff944 Changed the RB_PAUSE flag from 0x40000 to 0x100000 and marked the old
value as reserved for internal use in boot blocks, because RB_PAUSE
broke binary compatibility by usurping the RB_DUAL flag.  Probably no
one except me has boot blocks for which this matters, since most boot
blocks based on biosboot including pc98's boot2 can't boot elf kernels,
and /boot/loader doesn't properly pass flags set by the previous stage.

reboot.h:
Also mark the historical RB_PROBEKBD flag (0x80000) as reserved for
internal use in boot blocks.

boot2.c:

129540b834 Include <sys/reboot.h> the definition of RB_BOOTINFO. The previous
commit broke the world because it depended on namespace pollution that
was only in my version of <machine/bootinfo.h>.  The include was removed
in rev.1.63 after the last reference to it went away in rev.1.61.

c00209396c Fixed loss of setting of the RB_BOOTINFO flag in rev.1.43. Fixed wrong
comment about this flag in rev.1.61.  It is not historical like the
comment said; it is the flag that says that most of what is laboriously
put in the bootinfo struct is actually there.  Newer kernels were
bootable by even the broken boot2 without losing anything except the
symbol table, but older kernels need at least the memory sizes.

Restoring the "|" with RB_BOOTINFO that was lost in rev.1.43 costs 5
bytes.  The fix can be done in only 4 bytes by fixing some code that
was removed in rev.1.61 (put RB_BOOTINFO back in in the initial value
of "opts" and fix RBX_MASK to not clobber it.)

8e6206d943 Fix interactive booting:
o Revision 1.38 introduced the -n flag.  It conflicted with the
  RB_BOOTINFO flag, so was in effect always on.  Change the -n flag to
  be bit 0x1c instead of 0x1f.  This also had the consequence that a mal-formed
  /boot.config would render the system unbootable because the user was
  unable to enter anything at all on the command line.
o Remove the initialization of opt to be RB_BOOTINFO since we filter that bit
  out and do not otherwise use it.

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.

1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

losing the printf.  Shortening strings is probably a better option but this

870fb18bc1 Oops, the previous revision (1.35) broke booting from floppies
because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.

Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).
