all zcache1 patches

I say zcache1 because down the line, in 3.9-rc2 zcache is replaced
by zcache2 which had been residing in the ramster directory.

zcache1 is no longer being maintained after this zcache2 take-over
so there will be no more patches.

There were a few patches that due to pragmatism (laziness) I would
have had to have made significant difficult merges (E.g. merge tag
linux 3.6-rc6 into master etc...)

Also, I have no idea what zcache actually does.
