The number of bits for the shm is the leftover after some other relevant
bit numbers are substracted from the number of bits of an adress, which is
of cause allways 32 as everyone knows. Because on alpha more bits are used
for other purposes, less of the 32 bit are left for shm.

At least it was that way last time I loked at it.

May the Source be with you.

PS: Are there any problems known when compiling the latest kernels with a
fairly recent gcc? Mine don't want to boot at all. I wondering whether its
gcc or milo (which is pretty old on my Alpha).
