The VSIE code currently checks that the BSCA struct fits within a page, and returns a validity exception 0x003b if it doesn't. The BSCA is pinned in memory rather than shadowed (see block comment at end of kvm_s390_cpu_feat_init()), so enforcing the CPU entries to be on the same pinned page makes sense. Except those entries aren't going to be used below the guest, and according to the definition of that validity exception only the header of the BSCA (everything but the CPU entries) needs to be within a page. Adjust the alignment check to account for that.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
