We should not search for the kernel start address in __machine__create_kernel_maps(), because it's being used in the 'report' code path, where we are interested in kernel MMAP data address (the one recorded via 'perf record', possibly on another machine, or an older or newer kernel on the same machine where analysis is being performed) instead of in current kernel address. The __machine__create_kernel_maps() function serves purely for creating the machines kernel maps and setting up the kmap group. The report code path then sets the address based on the data from kernel MMAP event in the machine__set_kernel_mmap() function. The kallsyms search address logic is used for test code, that calls machine__create_kernel_maps() to get current maps and calls machine__get_running_kernel_start() to get kernel starting address. Use machine__set_kernel_mmap() to set the kernel maps start address and moving map_groups__fixup_end to be call when all maps are in place. Also make __machine__create_kernel_maps static, because there's no external user.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
