Should we add a proxy_port that does the v->p address translation?
Should the proxy port return a fault on translation errors, if we add one?
arch/alpha/alpha_linux_process.cc:
Syscalls use a memPort through the CPU now instead of a xc functional memory.
cpu/base.hh:
Add a pointer to the memPort syscalls will use. Should this be a proxy_port that does address translation?
cpu/exec_context.cc:
cpu/exec_context.hh:
Remove functional memory from the exec context
cpu/simple/cpu.cc:
Set the memPort to be used as the syscall port as the dcache port
sim/syscall_emul.cc:
sim/syscall_emul.hh:
Syscalls use a memPort through the CPU now instead of a xc functional memory.
Also, fix the fact that readStringFunctional doesn't return a fault... should proxy_port handle this because it is doing the translation?

amazingly we never did that before. Caused us to run out of
file descriptors in twolf.
sim/process.cc:
Add free_fd() method to free closed target fd in simulator fd map.
Rename open_fd() to alloc_fd() for symmetry with free_fd().

Add free_fd() method to free closed target fd in simulator fd map.
Rename open_fd() to alloc_fd() for symmetry with free_fd().
Crank up MAX_FD while we're at it.
sim/syscall_emul.cc:
Call free_fd() on process when target closes a file.
sim/syscall_emul.hh:
Process open_fd() renamed to alloc_fd().

We can now run the SimpleScalar wupwise binary
to completion on the test input.
Didn't have time to do more testing, but I fixed
a major problem w/getdirentries that should help
a lot more programs run.
arch/alpha/alpha_tru64_process.cc:
Add truncate, ftruncate, statfs, and fstatfs.
Add v4.x (pre-F64) stat, fstat, and lstat.
Add setsysinfo (though all it does is provide more
specific warning messages).
Fix subtle but major bug in getdirentries.
sim/syscall_emul.cc:
sim/syscall_emul.hh:
Add truncate, ftruncate, statfs, and fstatfs.

benchmarks for alpha-linux.
arch/alpha/alpha_linux_process.cc:
Added some more ioctl commands to ignore.
Set unlink and rename to the new functions.
Ignore setrlimit, times and rt_sigaction.
Should eventually provide a function for times.
arch/alpha/alpha_tru64_process.cc:
Added some more ioctl commands to ignore.
Set unlink and rename to the new functions.
Ignore setrlimit.
sim/syscall_emul.cc:
Added implementations for unlink and rename.
sim/syscall_emul.hh:
Added unlink and rename functions.
Added a couple more ioctl requests to ignore.
Print out the PC of any ioctl commands that fail.

interfaces, and specific support for Alpha Linux. Split syscall emulation
functions into several groups, based on whether they depend on the specific
OS and/or architecture (and all combinations of above), including the use of
template functions to support syscalls with slightly different constants
or interface structs.
arch/alpha/alpha_tru64_process.cc:
Incorporate full Tru64 object definition here, including structure and constant definitions.
This way we can wrap all of the functions inside the object, and not worry about namespace
conflicts because no one outside this file will ever see it.

LiveProcess is now effectively an abstract base class.
New LiveProcess::create() function takes an object file and dynamically picks the
appropriate subclass of LiveProcess to handle the syscall interface that file expects
(currently Tru64 or Linux).
