Hi,

The i386 allmodconfig builds of linux-next have been failing since
next-20100204 like this:

In file included from arch/x86/include/asm/uaccess.h:571,
from include/linux/uaccess.h:5,
from include/linux/highmem.h:6,
from include/linux/pagemap.h:10,
from include/linux/mempolicy.h:62,
from include/linux/migrate.h:5,
from mm/migrate.c:15:
In function 'copy_from_user',
inlined from 'do_pages_stat' at mm/migrate.c:1009:
arch/x86/include/asm/uaccess_32.h:212: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size is not provably correct

[Today's linux-next is the same except for the one line starting
"inlined" which is now:
inlined from 'do_pages_stat' at mm/migrate.c:1012:
]

I use gcc 4.4.3 for those compiles. (See
http://kisskb.ellerman.id.au/kisskb/buildresult/2118967/ for full logs.)

There doesn't seem to be any relevant change in the config from Feb 3 to
4:

+CONFIG_I2C_XILINX=m
+CONFIG_RADIO_SAA7706H=m

and nothing else jumps out. The i386 defconfig and allnoconfig builds do
not fail.
