Hi all,

I've got two questions in regard to building linux-2.6.9-rc2 for a mvme5100

Target info:
build platform: mvme5100, gcc-3.3.4, debian-testing, linuxppc_2_4_devel, 
default mvme5100 config
target platform: mvme5100

Questions 1:

I was getting this error when I tried to build the kernel:

  CC      arch/ppc/boot/common/bootinfo.o
  CC      arch/ppc/boot/common/misc-common.o
  CC      arch/ppc/boot/common/ns16550.o
arch/ppc/boot/common/ns16550.c:14: error: conflicting types for `outb'
include/asm/io.h:142: error: previous declaration of `outb'
arch/ppc/boot/common/ns16550.c:15: error: conflicting types for `inb'
include/asm/io.h:157: error: previous declaration of `inb'
make[2]: *** [arch/ppc/boot/common/ns16550.o] Error 1
make[1]: *** [arch/ppc/boot/common] Error 2
make: *** [zImage] Error 2

I changed arch/ppc/boot/common/ns16550.c so that it managed to compile 
based on what was in io.h, the patch for which is attatched, are these 
changes okay?


Question 2:

I'm now getting the error:

make[2]: *** [arch/ppc/boot/simple/zvmlinux] Error 1
make[1]: *** [simple] Error 2
make: *** [zImage] Error 2

Now I know isa_io_base is declared/defined in arch/ppc/kernel/pci.c so 
how is it supposed to link?

Ta,
dlg
