[PATCH] x86: Drop unused and needless config X86_64_SMP

[PATCH] x86: Drop unused and needless config X86_64_SMP

[Lukas Bulwahn]

From: Lukas Bulwahn <lukas.bulwahn@redhat.com>

As part of the commit 38a4968b3190 ("x86/percpu/64: Remove INIT_PER_CPU
macros"), the only use of the config option X86_64_SMP in the kernel tree
is removed. As this config option X86_64_SMP is just equivalent to
X86_64 && SMP, the source code in the tree just uses that expression in the
few places where needed. Note further that this option cannot be explicitly
enabled or disabled when configuring the kernel build configuration.

Drop this needless and unused config option. No functional change.
