Rather than tie this to KVMPPC_NR_LPIDS which is becoming more dynamic, fix it to 4096 (12-bits) explicitly for now. kvmhv_get_nested() does not have to check against KVM_MAX_NESTED_GUESTS because the L1 partition table registration hcall already did that, and it checks against the partition table size. This patch also puts all the partition table size calculations into the same form, using 12 for the architected size field shift and 4 for the shift corresponding to the partition table entry size.

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 Restructured Text 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.
