Enable kfence on book3s64 hash only when early init is enabled. This is because, kfence could cause the kernel linear map to be mapped at PAGE_SIZE level instead of 16M (which I guess we don't want). Also currently there is no way to - 1. Make multiple page size entries for the SLB used for kernel linear map. 2. No easy way of getting the hash slot details after the page table mapping for kernel linear setup. So even if kfence allocate the pool in late init, we won't be able to get the hash slot details in kfence linear map. Thus this patch disables kfence on hash if kfence early init is not enabled.

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.
