It's not that minimal it suggests. It removed asm/compat.h inclusion
from arch/s390/kernel/setup.c. This causes build failures on
!CONFIG_COMPAT:
arch/s390/kernel/setup.c: In function 'setup_addressing_mode':
arch/s390/kernel/setup.c:382: error: 'PSW32_ASC_SECONDARY' undeclared
(first use in this function)
arch/s390/kernel/setup.c:382: error: (Each undeclared identifier is
reported only once
arch/s390/kernel/setup.c:382: error: for each function it appears in.)
arch/s390/kernel/setup.c:389: error: 'PSW32_ASC_PRIMARY' undeclared
(first use in this function)

Perhaps asm/compat.h should be included from linux/compat.h
unconditionally...

But who defines is_compat_task *with* CONFIG_COMPAT on ia64?

fs/autofs4/inode.c: In function 'autofs4_fill_super':
fs/autofs4/inode.c:345: error: implicit declaration of function
'is_compat_task'

thanks,
