The PA-RISC ELF ABI puts the function pointer to be registered with atexit in %r23. Use this instead of passing in NULL. While it's unlikely to be used, doing the right thing is good.

[cross posting cause I'm not sure who should get this email] I am attempting to make ext3 work on the parisc kernel tree. So far I have successfully patched and have made the kernel compile w/ only two line changes to the source. I got ext3 from the cvs, and the parisc 2.4.9-pa17 kernel and I've patched the parisc kernel w/ the add-to-kernel.sh script. after a bit of fighting I got the kernel to comp...

The reason for this failure is, that fstype calls the pread() syscall, which has on some architectures with 32bit userspace a different calling syntax. I noticed this bug on hppa, but I...

Hello Samba users, as i still could not get samba to work on my hp 9000/720 workstation with debian linux, i asked for help on the parisc linux mailinglist. Here is an answer which blames glibc for the problem. Could someone please explain to me (from viewing this info) how to set compiler options/defines to get samba to work on this architecture ? Or what to do else ... Thanks. ----------------------------------------------------...

...ause uClinux *has* to use it. Unfortunately vfork() isn't allowed to use the stack *at all* across the system call -- including return address -- which means it needs an assembly wrapper on most architectures. I have tried implementing wrappers for most architectures, but I don't know parisc or s390/s390x well enough, and both architectures do seem to need it. So if you have either, I would appreciate it if you could pull the git version of the standalone klibc tree, and implement the appropriate vfork.S. I also need help *testing* the ARM wrapper I do have, since I currently have...
