Subject: [PATCH] [FEAT VS1804] include/boot/s390.h: add guard for `struct __vector128`
From: Marc Hartmayer <mhartmay@linux.ibm.com>

Summary:     genprotimg: Introduce new tool for the creation of PV images
Description: genprotimg takes a kernel, host-key documents, optionally an
             initrd, optionally a file with the kernel command line, and it
             generates a single, loadable image file. The image consists of a
             concatenation of a plain text boot loader, the encrypted
             components for kernel, initrd, and cmdline, and the
             integrity-protected PV header, containing metadata necessary for
             running the guest in PV mode. It's possible to use this image file
             as a kernel for zIPL or for a direct kernel boot using QEMU.

Upstream-Description:

include/boot/s390.h: add guard for `struct __vector128`

`linux/asm/types.h` also defines the struct `__vector128` so in order
             to avoid definition conflicts add the macro guard _S390_TYPES_H, which
             is defined in `linux/asm/types`. `linux/asm/types.h` is included by
             glib2, which is used by the PV tooling.
