While running cross compile tests for prpmc750 we got the following error that I think is related to the above patches.
UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD vmlinux init/built-in.o: In function `run_init_process': main.c:(.text+0x20): undefined reference to `kernel_execve' init/built-in.o: In function `do_linuxrc': do_mounts_initrd.c:(.init.text+0x3a98): undefined reference to `kernel_execve' arch/ppc/kernel/built-in.o: In function `execve': arch/ppc/kernel/entry.S:(.text+0x24a2): undefined reference to `errno' arch/ppc/kernel/entry.S:(.text+0x24a6): undefined reference to `errno' kernel/built-in.o: In function `____call_usermodehelper': kmod.c:(.text+0x163f8): undefined reference to `kernel_execve' make: [vmlinux] Error 1 (ignored) SYSMAP System.map powerpc-750-linux-gnu-nm: 'vmlinux': No such file make: [vmlinux] Error 1 (ignored) MODPOST vmlinux
Here is a patch that fixes the compile errors. I took the code from misc_32.S.
