linux-next: sparc tree build warning

[Stephen Rothwell]

Hi Dave,

Today's linux-next build (sparc defconfig) produced this warning:

In file included from arch/sparc/include/asm/uaccess.h:7,
                 from include/net/checksum.h:26,
                 from include/linux/skbuff.h:29,
                 from net/core/pktgen.c:141:
In function 'copy_from_user',
    inlined from 'pktgen_if_write' at net/core/pktgen.c:867:
arch/sparc/include/asm/uaccess_32.h:276: warning: call to 'copy_from_user_overflow' declared with attribute warning: copy_from_user() buffer size is not provably correct

and many more.

The sparc64 defconfig build produced many similar warnings:

In file included from arch/sparc/include/asm/uaccess.h:5,
                 from include/linux/uaccess.h:6,
                 from include/linux/highmem.h:7,
                 from include/linux/pagemap.h:11,
                 from include/linux/mempolicy.h:63,
                 from mm/mempolicy.c:69:
arch/sparc/include/asm/uaccess_64.h: In function 'compat_sys_get_mempolicy':
