From: Sean Christopherson Date: Tue, 26 Nov 2019 16:54:13 +0000 (-0800) Subject: vmw_balloon: Explicitly include linux/io.h for virt_to_phys() X-Git-Tag: block-5.6-2020-02-05~65^2~4 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=97976e01d3586e488b6c4c84881806d5d2960e6c;p=linux-block.git vmw_balloon: Explicitly include linux/io.h for virt_to_phys() 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.
