We've still got tip/tracing/immediates, with these commits from you:

 $ git-log-line linus.. arch/x86/kernel/immediate.c
 ee563d6: immediate values: jump liveliness
 e26875a: Immediate Values - Jump
 3fc8d03: Immediate Values - x86 Optimization NMI and MCE support

... but the topic is stalled right now, due to hpa having had 
objections. Have those concerns been resolved? (Peter Cc:-ed)

i'd have applied this fix, but it does not apply. The first chunk seems 
already be present (in a different form), the second chunk looks much 
different.
