[parisc-linux] 715/33 and HIL driver

[Kirk Bresniker]

I have never seen the shellpromt on my D320, but I am
getting the same thing as you.

| I have seen the shellprompt on my 715/33 using the CVS
| version 20000125 and defconfig (and removing the debug
| printk's from sched.c + system.h). But activating
| CONFIG_HIL leads to the following boot messages:
| 
| pagetable_init
| kernel BUG at bootmem.c:163!
| kernel BUG at bootmem.c:203!

This happened after I did an rm .config; make oldconfig dep clean Image.
Before that I was getting to the switch_to endless loop, but no prompt.

Here is what I get:

In looking at the code, what is barfing is the last call to
__alloc_bootmem() at the end of pagetable_init() in
arch/parisc/mm/init.c. This is the call which I believe is 
supposed to allocate page zero and in prep to clear it out.

Here is what I have defined in my include/linux/autoconf.h
