This is a gcc-4.5 issue. Whether it's also something that we should
change in the kernel is unclear, but at least as of now, the rule is
that you cannot compile the kernel with gcc-4.5. No idea whether the
compiler is just entirely broken, or whether it's just that it
triggers something iffy by being overly clever.
What you cited talks about lossage in the metadata for ftrace syscall
tracing. It's hardly fatal. There's already a fix on its way upstream,
and it appears to have been nothing more than default alignment changes vs
the highly-fragile ftrace hooey. "compiler is just entirely broken" is
laughable even to have speculated about for the actual facts here.
Thanks,
Roland
