486 support was removed in April:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0972ba5605a0a0cd8a9e74558b97a9c9626adfb5

586-class CPUs remain supported but only if they have RDTSC (so AMD K5
is gone)

Pentium and later are still supported AFAIK.

Looking at non-x86 platforms, armv7 support could in in the mid 2030s:

Couldn’t find anything definitive about other architectures.
