Mikulas Patocka 0ef38d70d4 alpha: fix broken network checksum 
The patch 3ddc5b46a8 breaks networking on
alpha (there is a follow-up fix 5cfe8f1ba5,
but networking is still broken even with the second patch).

The patch 3ddc5b46a8 makes
csum_partial_copy_from_user check the pointer with access_ok. However,
csum_partial_copy_from_user is called also from csum_partial_copy_nocheck
and csum_partial_copy_nocheck is called on kernel pointers and it is
supposed not to check pointer validity.

This bug results in ssh session hangs if the system is loaded and bulk
data are printed to ssh terminal.

This patch fixes csum_partial_copy_nocheck to call set_fs(KERNEL_DS), so
that access_ok in csum_partial_copy_from_user accepts kernel-space
addresses.
