Our .data section is missing PAGE_ALIGNED_DATA() which contains, amongst other things, the vdso page. This creates a System.map that looks like this: c15769a8 D _edata c1577000 d vdso_data_store c1578000 D __start___bug_table c1580544 D __stop___bug_table c1580544 B __bss_start By using RW_DATA_SECTION() we pick whatever generic sections might be added in the future and have page-aligned data next to other strongly aligned data. Furthermore we now include the entire thing, including the bug table, in the data accounting surrounded by _sdata/_edata. While at it let's also remplace the open coded .init.data by its equivalent INIT_DATA_SECTION().

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.
