commits. For some reason I thought the scale factor was a shift count
rather than the multiplicand (that is, I thought leal (%eax,%edx,4) was
going to generate %eax + %edx << 4 rather than %eax + %edx * 4). What
I need is to multiply by 16 to convert a real-mode (seg, offset) tuple
into a flat address. However, the max multiplicand for scaled/index
addressing on i386 is 8, so go back to using a shl and an add.
- Convert two more inter-register mov instructions where we don't need to
preserve the source register to xchg instructions to keep our space
savings.

Move the relocation definitions to the common elf header so that DTrace
can use them on one architecture targeted to a different one.
Add the additional ELF types defines in Sun's "Linker and Libraries"
manual.
there are enough places in the DTrace kernel/module sources that
having a header that gathers together all the individual elf headers
is convenient.
Note that the Solaris compatibility definions are conditionally

unmount when mp structure is reused while waiting for coveredvp lock.
Introduce struct mount generation count, increment it on each reuse and
compare the generations before and after obtaining the coveredvp lock.

close and re-open the default pipe instead of relying on the host
controller driver to notice the changes. Remove the unreliable code
that attempted to update these fields while the pipe was active.
This fixes a case where the hardware could cache and continue to
use the old address, resulting in a "getting first desc failed"
error.

The parallel LINT build sometimes broke if kernel-depend wasn't
fast enough in generating ukbdmap.h. If someone thinks this
option would still be useful for the module, a proper fix is
to add the code generating ukbdmap.h into modules/ukbd/Makefile
and backing this change out.
Split subr_clock.c in two parts (by repo-copy):
subr_clock.c contains generic RTC and calendaric stuff. etc.
subr_rtc.c contains the newbus'ified RTC interface.
Centralize the machdep.{adjkerntz,disable_rtc_set,wall_cmos_clock}
sysctls and associated variables into subr_clock.c. They are
not machine dependent and we have generic code that relies on being
present so they are not even optional.
