[pca] New kernel patch 127127-11

[Dominique Frise]

Here below what we noticed about 127127-xx patches.

This "deferred-activation" patch can not be applied on a system with zones in 
multi-user: you have to bring it to single-user.
See http://www.sun.com/bigadmin/sundocs/articles/patch-wn.jsp

All our system with only a global zone could be patched in multi-user (we do 
not have any NFS server on Solaris).
