same email thread, but reducing quoted portions...

applying patch-3.14.17-vs2.3.6.13.diff to linux 3.14.2[23456] fails in both

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

1. acquire 3.14.26
2. apply patch-3.14.17-vs2.3.6.13.diff
3. apply patch-3.14.17-19-include_hash-vs2.3.6.13.diff [1]
4. apply patch-3.14.17-19-remove_caps-vs2.3.6.13.diff [2]
5. apply patch-3.14.17-24-include_ipv6-vs2.3.6.13.diff [3]
6. 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
guest.
