This patch allows __cpu_setup to be invoked with one of these flags, ARM64_CPU_BOOT_PRIMARY, ARM64_CPU_BOOT_SECONDARY or ARM64_CPU_RUNTIME. This is required as some cpufeatures need different handling during different scenarios. The input parameter in x0 is preserved till the end to be used inside this function. There should be no functional change with this patch and is useful for the subsequent ptrauth patch which utilizes it. Some upcoming arm cpufeatures can also utilize these flags.

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.
