[PATCH v2 07/12] virt: vbox: Explicitly include linux/io.h to pick up various defs

From: Sean Christopherson
Date: Tue Nov 26 2019 - 11:54:57 EST


Through a labyrinthian sequence of includes, usage of page_to_phys(),
virt_to_phys() and out*() is dependent on the include of asm/io.h in
x86's asm/realmode.h, which is included in x86's asm/acpi.h and thus by
linux/acpi.h. Explicitly include linux/io.h to break the dependency on
realmode.h so that a future patch can remove the realmode.h include from
acpi.h without breaking the build.
