In addition to common VMCOREINFO's defined in crash_save_vmcoreinfo_init(), we need to know, for crash utility, - kimage_voffset - PHYS_OFFSET to examine the contents of a dump file (/proc/vmcore) correctly due to the introduction of KASLR (CONFIG_RANDOMIZE_BASE) in v4.6. - VA_BITS is also required for makedumpfile command. arch_crash_save_vmcoreinfo() appends them to the dump file. More VMCOREINFO's may be added later.

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.
