| |
Linus,
The patch below (for 2.4.0-test11pre2) makes include/asm-i386/elf.h's ELF_PLATFORM be an alias for system_utsname.machine. bugs.h (which initialises system_utsname.machine) and elf.h use the same algorithm to map boot_cpu_data.x86 to a name, so it makes sense to share the name between them, especially if we ever come up with a better naming scheme (just one place to fix, not two).
This doesn't change any current 2.4 behaviour wrt to the Pentium IV. However, 2.2.18pre's version of elf.h is currently broken for the Pentium IV, and I want the same "nice" fix in both kernels. (I'm sending an equivalent patch to Alan for 2.2.18pre.)
