that were added to sparc64 and later powerpc, really should have been in
the MI area. But changing that now with insufficient preperation will
just cause too much pain.
Move MD_FETCH() to the MI sys/linker.h file to avoid another two copies
of it.
were, they are not safe to use outside of the kernel since these values
can change at kernel compile time - ie: we do not want them compiled into
userland binaries.
lot of work to make this driver work under current. In the past when
people wanted to remove xten, I was the only one in the way. After
talking to fsmp@ (last person to make real changes to this driver)
about this, I'm convinced it is better left in the dust-bin of history

syscall return values should be cleared. The system calls
getcontext() and swapcontext() want to return 0 on success
but these contexts can be switched to at a later time so
the return values need to be cleared in the saved register
sets. Other callers of get_mcontext() would normally want
the context without clearing the return values.
Remove the i386-specific context saving from the KSE code.
get_mcontext() is not i386-specific any more.
Fix a bad pointer in the alpha get_mcontext() code. The
context was being bcopy()'d from &td->tf_frame, but tf_frame
is itself a pointer, so the thread was being copied instead.

there with this chip but don't have all the USB vendor/device IDs.
Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.
Ignoring maxsegsz may lead to fatal data corruption for some devices.
