The are two major support <emphasis>&architecture;</emphasis> flavors:
9
PA-RISC 1.1 and PA-RISC 2.0. The PA-RISC 1.1 architecture is targeted
10
at 32-bit processors whereas the 2.0 architecture is targeted to
11
the 64-bit processors. Some systems are able to run either kernel.

In both cases, the userland is 32-bit. There is the possibility of
13
a 64-bit userland in the future.
