Instead of passing each start address into is_vmalloc_or_module_addr() to decide whether it falls into either the VMALLOC or the MODULES region, we can simply check the type field of the current kcore_list entry, since it will be set to KCORE_VMALLOC based on exactly the same conditions. As a bonus, when reading the KCORE_TEXT region on architectures that have one, this will avoid using vread() on the region if it happens to intersect with a KCORE_VMALLOC region. This is due the fact that the KCORE_TEXT region is the first one to be added to the kcore region list.

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.
