It appears that (X86_64 || X86_32) is always true on x86.

This logical OR directive was introduced in
commit 6ea3038648da ("arch/x86: remove depends on CONFIG_EXPERIMENTAL")
probably by a trivial mistake.

x86/Kconfig: Always enable ARCH_SPARSEMEM_ENABLE

It appears that (X86_64 || X86_32) is always true on x86.

This logical OR directive was introduced in:

  6ea3038648da ("arch/x86: remove depends on CONFIG_EXPERIMENTAL")

By (EXPERIMENTAL && X86_32) turning into (X86_32). Since
this change was an identity transformation, nobody noticed
that the condition turned into 'true'.
