[Qemu-arm] pull requests and ARM patches during May

[Peter Maydell]

Hi all; I'm taking a break during May and won't be reading work
emails during that time. Alex Bennée has volunteered to look after
ARM patches, and Stefan Hajnoczi has agreed to handle applying
pull requests. People working on ARM related patches can also
help each other out by reviewing each others' patches.

See you all in June :-)

thanks
