Description:
When trying to compile my own kernel with device pst in configuration
file, process fail with message:

As we see from /usr/src/sys/dev/pst/pst-iop.h, initiator_context and
transaction_context fields of driver message struct are declared as u_int32_t,
which doesn't match pointer size on 64-bit processor.
How-To-Repeat:
On amd64 machine include
device pst
in your config file and try compile kernel.
Fix:
The controller is very old hardware and one of fix may be exclude it from
available devices on amd64 platform.
Yes, this driver is not supported on amd64. Do you need it to work? You
would need to implement a cookie hash table of some sort to map transaction
context IDs to request pointers. If you do not need it, we should probably
disable it on amd64 as no one else has asked about it.
