Will linux distributions automatically use this compilation option (or its analog in GCC) for packages from now until forever, even if a faster mitigation is added to CPUs?
I use a binary distro and definitely don't want to be running massively slowed-down software mitigations on a corrected CPU.
Although actually, we already are - binary distros already don't take into account per-microarchitecture scheduling, nor any ISA extensions above a common baseline (e.g. just SSE2, no autovectorising to AVX2 etc).
This might provide enough impetus to restructure how binary distros work and get the whole distro compiled with some newer CPU flags (march={first corrected architecture}?) but in the short term i assume every package will take the hit.
