[Skiboot] Stewart on vacation

[Stewart Smith]

Hi all,

An FYI for those I haven't told yet. From August 1st until August 9th
im' on vacation. My IBM laptop will be on a different continent to
myself, which means I will have absolutely no way of logging into any
IBM thing. This is by design :)

Hopefully there'll be nothing urgent that needs to be merged, but if so
BenH wil maintain the skiboot trees in my absence.
