The HARDEN_EL2_VECTORS config maps vectors at a fixed location on cores which are susceptible to Spector variant 3a (A57, A72) to prevent defeating hyp layout randomization by leaking the value of VBAR_EL2. Since this feature is only applicable when EL2 layout randomization is enabled, unify both behind the same RANDOMIZE_BASE Kconfig. Majority of code remains conditional on a capability selected for the affected cores.

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.
