2.3.33 broken on Alpha (EV4), with fix

Linux 2.3.33 will not compile out of the box on alpha, due to what seems to
me (I don't understand the code) to be a typo in asm/pgtable.h, see the
diff below.

Even after fixing that, the Makefile logic to determine optimisation is
broken, which results in compiling an EV6 kernel for EV4, which gives an
alignment fault on boot. (See attached patch.)

Come on guys, not all of us have DS20s and XP9000s...

Having got this far, the system craps up with the NCR 53C7,8XX driver
declaring that it can't find a known I/O or memory mapping. Any ideas about
what may be going on here?

I am suspicious of the FIXME: around line 878 of drivers/scsi/53c7,8xx.c.

System is an EV4 Avanti, booting via SRM/MILO.
