Subject: [PATCH] [FEAT VS1804] zipl: move __always_inline/barrier/__pa32/pa to zt_common.h
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:

zipl: move __always_inline/barrier/__pa32/pa to zt_common.h

Move `__always_inline/barrier/__pa32/pa` to `lib/zt_common.h` as this
             is non-architecture dependent code.
