Subject: x86/smpboot: Move data structure to its primary usage scope
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db6a00b4bed3abbb038077ba4fdc5be481fe5559;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86/smpboot: Move data structure to its primary usage scope

Makes the code more readable by moving variable and usage closer
to each other, which also avoids this build warning in the
!CONFIG_HOTPLUG_CPU case:

  arch/x86/kernel/smpboot.c:105:42: warning: ‘die_complete’ defined but not used [-Wunused-variable]
