- sys/modules/md/Makefile rev 1.14:

  Rename GEOM class kernel module g_md.ko to geom_md.ko for
  consistency with the rest.  The g_md.ko is now a hardlink of
  geom_md.ko for backward compatibility.

- sys/sys/mdioctl.h rev 1.21:

  Removed (now unused) #define.

- sys/boot/forth/loader.conf rev 1.102:

  Add more GEOM classes to defaults/loader.conf. Add references to
  manual pages to those already present.

- sbin/mdconfig/mdconfig.c rev 1.45:

  Simplify mdmaybeload() function.

MFC accumulated changes to sys/boot/. Notable changes include:

2006-10-01T12:07:08+00:00

- Make 4G of memory directly accesible to the i386 loader(8).  This
  allows using memory above first megabyte for heap if necessary.
  (by sobomax@)

- If loader is compiled with LOADER_BZIP2_SUPPORT, allocate heap in
  the last 3MB of physical memory.  This provides enough room for
  decompression and is safe to use with PAE and amd64 kernels.  This
  makes bzip2 support practically useable.
  (by sobomax@)

- Drop the gateA20() function in the loader as it is unused.

- Make the PROBE_KEYBOARD compile-time option of pxeboot(8) better
  resemble the -P option in boot2, i.e., if keyboard isn't present
  then boot with both RB_SERIAL and RB_MULTIPLE set.

- Document BOOT_PXELDR_ALWAYS_SERIAL and BOOT_PXELDR_PROBE_KEYBOARD
  options of pxeboot(8).
