| |
Alan,
2.2.18pre's include/asm-i386/elf.h is currently broken for the Pentium IV (out of bounds array indexing error). Since ELF_PLATFORM is identical to system_utsname.machine, the patch below simply tosses ELF_PLATFORM's broken name generation code and uses system_utsname.machine instead. There is no behavioural change for P6 and lesser CPUs.
