Hi list, I have worked on the porting of UML, User Mode Linux, on ppc arch and I encountered a big stop, since I can not find the way out of this issue:

Referring to the following doc from IBM, you can have an idea of what _SDAx_BASE_ mean (page 7): http://www-3.ibm.com/chips/techlib/techlib.nsf/techdocs/852569B20050FF77852569970071B0D6/$file/eabi_app.pdf how can I proceed with the definition of there ppc symbols on the linker? They are called on the <linux-source-dir>/script/kallsyms.c in the kernel original way and it is not touch by the patch. Can anyone help me? I found on web that Renzo Davoli encountered the same problem and there is still no solution to it. Thank you in advance for your precious help Cheers SteX PS: I work on an Apple Powerbook Aluminum 15" -- Stefano Melchior, GPG key = D52DF829 - <[EMAIL PROTECTED]> http://etinarcadiaego.dyndns.org -- http://www.stex.name
