[parisc-linux] missing system calls ?

[parisc-linux] missing system calls ?

[Helge Deller]

I just tested the patch "missing system calls" patch by David Woodhouse (http://thread.gmane.org/gmane.linux.ports.ppc64.devel/16991) 
and the additional patch by David Miller (http://thread.gmane.org/gmane.linux.ports.ppc64.devel/16991/focus=502554) on top of it.
I really liked the patches.

Here is the result for my parisc-linux tree:

Thanks Kyle !

So parisc-linux has all important (and currently on PA possible) syscalls wired up.
Nice to know.

We don't support non-realtime signals (the syscalls are rt_*)

umount2

> init/missing_syscalls.h:248:3: warning: #warning syscall select not implemented

newselect

obsolete

we don't use the socketcall multiplexer (presumably because we don't need
to put the args on the stack) for socket/bind/connect/ etc...

> init/missing_syscalls.h:353:3: warning: #warning syscall ipc not implemented

same story as socketcall, obsolete multiplexed syscall

> init/missing_syscalls.h:749:3: warning: #warning syscall fadvise64 not implemented

sys_fadvise64_64 versus fadvise64 is a reordering of syscall args, presumably
because loff_t is 64bit and needs to be passed in pairs.

Your kernel is too old. 2.6.21-rc3 has this.

> init/missing_syscalls.h:809:3: warning: #warning syscall utimes not implemented

Dunno about this one. sys_utimes seems to just call futimesat anyways.

> init/missing_syscalls.h:845:3: warning: #warning syscall kexec_load not implemented

nobody's implemented kexec yet. :)
