Brian DegenhardtandClaude Fable 5 bcb8edaa9f FX-15: SD865 iTLB A/B — mechanism confirmed, throughput neutral, kept
ITLB_WALK -15% to -35% and L1I_TLB_REFILL -4% to -59% across 4 titles,
but cycles/wall flat (A77 baseline iTLB pressure already negligible;
1280-entry L2 TLB covers the live JIT footprint in 4K pages). THP
madvise stays default-ON: zero cost, no regression, in-order A53 upside.
Adds the reusable A/B harness (env-toggle arms + in-run smaps THP probe).
