[PATCH v2 08/12] vmw_balloon: Explicitly include linux/io.h for virt_to_phys()

From: Sean Christopherson
Date: Tue Nov 26 2019 - 11:55:10 EST


Through a labyrinthian sequence of includes, usage of virt_to_phys() 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.
