    x86/init: Use a platform legacy quirk for EBDA · 1330e3bc
    Luis R. Rodriguez 提交于
    This replaces the paravirt_enabled() check with a
    proper x86 legacy platform quirk.
    
    As per 0-day, this bumps the vmlinux size using i386-tinyconfig as
    follows:
    
    TOTAL   TEXT   init.text   x86_early_init_platform_quirks()
    +39     +35    +35         +25
    
    That's a 4 byte total overhead, the rest is all cleared out
    upon init as its all __init text.
    
    v2: document 0-day vmlinux size impact
