    Subject[124/200] fs/compat_rw_copy_check_uvector: add missing compat_ptr call
    2.6.34-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Heiko Carstens <heiko.carstens@de.ibm.com>

    commit 7cbe17701a0379c7b05a79a6df4f24e41d2afde8 upstream.

    A call to access_ok is missing a compat_ptr conversion. Introduced with
    b83733639a494d5f42fa00a2506563fbd2d3015d "compat: factor out
    compat_rw_copy_check_uvector from compat_do_readv_writev"

    fs/compat.c: In function 'compat_rw_copy_check_uvector':
    fs/compat.c:629: warning: passing argument 1 of '__access_ok' makes pointer from integer without a cast
