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.
