Pull objtool updates from Ingo Molnar: "This is an extensive rewrite of the objdump tool to track all stack pointer modifications through the machine instructions of disassembled functions found in kernel .o files. This re-design removes the prior dependency on CONFIG_FRAME_POINTERS, with the goal to prepare the tool to generate kernel debuginfo data in the future. There's also an increase in checking/tracking robustness as a side effect as well. No (intended) changes to existing functionality" * 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: objtool: Silence warnings for functions which use IRET objtool: Implement stack validation 2.0 objtool, x86: Add several functions and files to the objtool whitelist objtool: Move checking code to check.c
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.
