From 69732102426b1c55a257386841fb80ec1f425d32 Mon Sep 17 00:00:00 2001 From: Pingfan Liu Date: Tue, 16 Jul 2019 16:40:24 +0800 Subject: x86/realmode: Remove trampoline_status There is no reader of trampoline_status, it's only written. It turns out that after commit ce4b1b16502b ("x86/smpboot: Initialize secondary CPU only if master CPU will wait for it"), trampoline_status is not needed any more.
