When we take a fault we can't handle, we try to dump some relevant information, but we're not consistent about doing so. In do_mem_abort(), we log the full ESR, but don't dump a page table walk. In __do_kernel_fault, we dump an attempted decoding of the ESR (but not the ESR itself) along with a page table walk. Let's try to make things more consistent by dumping the full ESR in mem_abort_decode(), and having do_mem_abort dump a page table walk. The existing dump of the ESR in do_mem_abort() is rendered redundant, and removed.

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.
