Re: Compiling kernel 2.4.20 on m68k

[Lance Tagliapietra <lancetag@luminet.net>]

Well,

That almost worked. I did the make oldconfig and the rest of the
procedure as it was described I still get the missing reference to
is_dumpable as described in the quoted text below (in
access_process_vm).  The floppy_hardint errors are corrected.  I've
compared the .config file to the 2.4.20 config in my /boot, and the only
difference is CONFIG_NLS_DEFAULT has a value of "iso8859-1" vs "cp437"
for the one in my /boot.  I'm not sure if that is significant.

Any suggestions on how to correct the is_dumpable missing symbol?
