Subject: [patch 3/3] nfs: remove 8 bytes of padding from struct nfs_fattr on 64 bit builds

From: Richard Kennedy <[email protected]>

remove 8 bytes of padding from struct nfs_fattr on 64 bit builds

This also removes padding from several nfs structures, including
16 bytes from nfs4_opendata, nfs4_createdata,nfs3_createdata
& 8 bytes from nfs_read_data,nfs_write_data,nfs_removeres,nfs4_closedata

This also reduces the reported stack usage of many nfs functions (30+).
