@ljs when does it matter? the only thing I know about it is that the kernel does not have struct page when pfn_valid() is false.

[Intel Publishes "X86-S" Specification For 64-bit Only Architecture]( https://www.phoronix.com/news/Intel-X86-S-64-bit-Only )

Not booting from real mode (-> protected mode -> long mode) anymore.
Still seems to support running 32 bit applications on 64 bit kernel.

Wait, who wants to run 32 bit kernel on 64 bit processors?
How much silicon is saved with this new ISA?
