Re: 2.6.26-rc5-mm3

[Byron Bradley <byron.bbradley@gmail.com>]

Looks like x86 and ARM both fail to boot if PROFILE_LIKELY, FTRACE and 
DYNAMIC_FTRACE are selected. If any one of those three are disabled it 
boots (or fails in some other way which I'm looking at now). The serial 
console output from both machines when they fail to boot is below, let me 
know if there is any other information I can provide.
