It's incorrect to iterate over all the possible CPUs to update the sibling masks when any CPU is hotplugged in. In case the topology siblings masks of the CPU is removed when is it hotplugged out, we end up updating those masks when one of it's sibling is powered up again. This will provide inconsistent view. Further, since the CPU calling update_sibling_masks is yet to be set online, there's no need to compare itself with each online CPU when updating the siblings masks. This patch restricts updation of sibling masks only for CPUs that are already online. It also the drops the unnecessary cpuid check.

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. 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.
