all macros in ev5.hh to inline functions or constant typed
variables and make them follow our style while we're at it.
All of the stuff in this file actually belongs in the ISA
traits code, but this is a first step at getting things done
in the right manner.

kern/tru64/tru64_events.cc:

arch/alpha/ev5.hh:
Macros are nasty, so let's get rid of them. Convert all
all macros to inline functions or constant typed variables.
Make them follow our style while we're at it.
All of the stuff in this file actually belongs in the ISA
traits code, but this is a first step at getting things done
in the right manner.
arch/alpha/isa_traits.hh:
move some of the ev5 specific code into the isa
arch/alpha/vtophys.cc:
base/remote_gdb.cc:
deal with isa addition
cpu/exec_context.hh:
be less isa specific and use the isa traits to figure out
what we can.
dev/alpha_console.cc:
dev/pciconfigall.cc:
dev/tsunami_cchip.cc:
dev/tsunami_io.cc:
dev/tsunami_pchip.cc:
dev/uart.cc:
deal with changes in ev5.hh
I don't believe this masking is actually necessary. We should
look at removing it later.
dev/ide_ctrl.cc:
sort #includes
deal with changes in ev5.hh
