Hi,

2.6.0-test9 does not compile on sparc64:

(...)
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
drivers/built-in.o(.text+0x55ecc): In function `vgacon_do_font_op':

drivers/built-in.o(.text+0x56264): In function `vgacon_do_font_op':

drivers/built-in.o(.text+0x56288): In function `vgacon_do_font_op':
: undefined reference to `vga_readb'
make: *** [.tmp_vmlinux1] Error 1

Looks like a missing definition. For other architectures there is a
definition in include/asm-[$arch]/vga.h.

Kind regards
