[PATCH] PPC fixes

[Franz S. <Fra...@la...>]

Hi,

the subject says it all, some fixes to let PPC compile again, add 2.4 kernel 
syscalls, correct a few syscall entries. The sys_old_mmap->sys_mmap change 
fixes the long-standing "ptrace: umoven: Input/output error" problem and 
passes correct values to print_mmap() now.

Franz.
