Subject: x86: move apicid mappings to smpboot.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=acbb67341805d3b9ef263d8cbd103a6054164491;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

x86: move apicid mappings to smpboot.c

They are i386 specific (the x86_64 definitions live
elsewhere, and should remain there), so are enclosed around
an ifdef
