One minor nit below, but with or without that change,

if (IS_ENABLED(CONFIG_X86_VSYSCALL_EMULATION) user_pgd !=

That has the advantage of ensuring that the code continues to compile.
(Given that you haven't removed level3_user_vsyscall, that should work.)

subsequent items display as part of the EXPERT menu again; the EMBEDDED
menu now appears as the next top-level item in the General Setup menu,
which makes General Setup much shorter and more usable.
