Hi; various build or test failures (5 total):

1) OSX:

/Users/pm215/src/qemu-for-merges/ui/cocoa.m:1478:9: error: implicit
declaration of function 'cpu_throttle_set' is invalid in C99 [-

2) aarch64 and aarch32 linux:

3) PPC64 had a failure on iotest 030 (though I think this may
be an intermittent in master):
