If init fails, we need execute two levels rollback operations: the first level is for the failed CPU rollback operations, the second level is to iterate all succeeded CPUs to cancel their registration; currently the code uses one function to finish these two levels rollback operations. This commit is to refactor rollback operations, so it adds a new function arm_idle_init_cpu() to encapsulate one specified CPU driver registration and rollback the first level operations; and use function arm_idle_init() to iterate all CPUs and finish the second level's rollback operations.

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.
