Trinity for PA-RISC

[Rolf Eike Beer <eike-kernel@sf-tec.de>]

[-- Attachment #1.1: Type: text/plain, Size: 639 bytes --]

Hi all,

out of boredom I did the first steps to port trinity to PA-RISC. The second 
patch is needed to get it compile, but since those headers are apparently not 
needed on other archs I suspect something is wrong with the PA-RISC headers. 
The implementation for some syscalls is missing, I just picked up what was 
available by default. Also everything currently is 32 bit. In contrast to what 
other archs do there currently is only a 32 bit userspace on PA-RISC, but 
there are many systems with a 64 bit userspace.

I have the hope that one of the usual suspects would use this to hammer on the 
kernel and fix the fallout. ;)

Eike
