Andi Kleen 2b16a23538 x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection 
Need this in the next patch in time_init and that happens early.

This includes a minor fix on i386 where early_intel_workarounds()
[which is now called early_init_intel] really executes early as
the comments say.

Thomas Gleixner c1e3619edd x86: print info about late C1E detection on 32bit as well 
Some BIOSes set the C1E flag only on the second core. Print a warning so
the Firmware Toolkit can check for it.
