Hello,
I've found two compilation problems with UML (both are present in
2.6.16-rc4 kernels). The problem is with processor type selection.
1) If I select processor type i386 the compilation fails with:
CC arch/um/kernel/asm-offsets.s
In file included from include/asm/atomic.h:9,
from include/linux/spinlock.h:231,
from include/linux/capability.h:45,
from include/linux/sched.h:7,
from arch/um/include/sysdep/kernel-offsets.h:2,
from arch/um/kernel/asm-offsets.c:1:
include/asm/arch/atomic.h: In function `atomic_add_return':
include/asm/arch/atomic.h:192: error: structure has no member named
`x86'
make[1]: *** [arch/um/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2
2) If I select Athlon/Duron processor I get:
CC arch/um/kernel/asm-offsets.s

Please CC me in reply as I'm not in the list.
