the below referenced patches account for the change in patch hunk context and
the masking of CAP_CONTEXT.

1. acquire linux-3.10.63
2. apply patch-3.10.53-vs2.3.6.8
3. apply patch-3.10.53-55-vs2.3.6.8.diff [0]
4. apply patch-3.10.53-56-vs2.3.6.9.diff [1]
5. manually fix the Makefile reject (EXTRAVERSION)

i've successfully built the resulting kernel and tested it in virtualbox
against testme.sh and testfs.sh, and started-entered-exited-stopped a vserver
