[PATCH] wire up support for the Alpha architecture

[PATCH] wire up support for the Alpha architecture

[Vince Weaver]

Will Deacon has more exotic hardware than I do: he sent this patch
against my perf_fuzzer to add Alpha support (he already used it to find a 
kernel bug).

Anyway since I use the trinity headers, the patch applies equally well 
against trinity.  

I'm not sure enough with my git skills to know if sending a patch like 
this will preserve attributions properly, so I apologize if this breaks 
somehow.

Looks like git-am did the right thing.

I only just realised... syscalls-alpha.h is missing from this patch.

You're right, the patch was originally against perf_fuzzer which doesn't 
need the various syscall includes.

I've cc'd Will Deacon, the original author, in case he's not on this list.

I wish I still had access to some actual Alpha hardware.

I'll try and find some time to generate that file.

You can get some off ebay, but you'll probably be bidding against me :)

So the weather was crap this weekend. Patch below.

My libc headers were slightly out of date, so I also had to hack up some
definitions for the EFD_* flags in fds.c (not included here).

Subject: [PATCH] alpha: add Linux syscall table numbers

Crikey, Alpha's syscall table is a right mess. Anyway, with enough sed
and perl-fu, here's something that looks about right for trinity. I had
to hand-hack the result to remove a whole bunch of obsolete syscalls
that trinity doesn't care about.

I also fixed up some missing Alpha ptrace requests with dummy values.

I don't know anything about alpha, but does the kernel actually
implement those OSF syscalls ? If not, it's unlikely we're going to
implement them in trinity, so we could probably do the same thing we did on ia64, and

#define SYSCALL_OFFSET 300 and skip all those ni_syscall entries.

Or am I missing something ?

Well, fork() is still syscall number 2, for example. I don't think we can
tidy this up with a simple offset unfortunately :(

Ah, I missed that. Now I see why you said it was a mess. Ok, I'll apply your patch as is.

thanks,
