The attached minimal config does not compile on ppc64.
I was able to boot the resulting binary with this patch.

I already fixed this some time ago, but the patch must have disappeared.

Right fix is to declare compat_sys_socketcall as as cond_syscall() 
in sys.c

Olaf, as I requested of you last time, please use attachments for
your patches since I can never apply them cleanly when you
inline them to the main body text.

Thanks a lot.

Hi everyone,

            I have got a small problem regarding configuring my ethernet
card,while loading the eth0 driver the kernel performs auto-probing for the
device and configures the eth0 to half-duplex.

I used command line arguments while loading modules
insmod 8139too io=0x280 irq=10 duplex=2

but still it performs the autoprobing overriding the parameters.

Please help me out of this problem,i want to configure my ethernetcard to
fullduplex.

Waiting for a reply...

With Regards,
Pranav.

8139too module does not take any arguments like io= or irq=.  PCI cards 
do not need such parameters.

You may use ethtool to select half-duplex or full-duplex.

Good Day,

Forgive my indignation if this message comes to you as a surprise and may offend your personality for contacting you without your prior consent and writing through this channel.

I came across your name and contact on the course of my personal searching when i was searching for a foreign reliable partner. I was assured of your capability and reliability after going true your profile.

I'm (Miss. Sandra) from Benghazi libya, My father of blessed memory by name late General Abdel Fattah Younes who was shot death by Islamist-linked militia within the anti-Gaddafi forces on 28th July, 2011 and after two days later my mother with my two brothers was killed one early morning by the rebels as result of civil war that is going on in my country Libya, then after the burial of my parents, my uncles conspired and sold my father's properties and left nothing for me. On a faithful morning, I opened my father's briefcase and discover a document which he has deposited ($6.250M USD) in a bank in a Turkish Bank which has a small branch in Canada with my name as the legitimate/next of kin.

You will also be responsible for the investment and management of the fund for me and also you will help me get a good school where i will further my education.
I agreed to give you 40% of the $6.250M once the transfer is done. this is my true life story, I will be glad to receive your respond soonest for more details to enable us start and champion the transfer less than 14 banking days as i was informed by the bank manager.
