This adds emulation for the following integer loads and stores, thus enabling them to be used in a guest for accessing emulated MMIO locations. - lhaux - lwaux - lwzux - ldu - lwa - stdux - stwux - stdu - ldbrx - stdbrx Previously, most of these would cause an emulation failure exit to userspace, though ldu and lwa got treated incorrectly as ld, and stdu got treated incorrectly as std. This also tidies up some of the formatting and updates the comment listing instructions that still need to be implemented. With this, all integer loads and stores that are defined in the Power ISA v2.07 are emulated, except for those that are permitted to trap when used on cache-inhibited or write-through mappings (and which do in fact trap on POWER8), that is, lmw/stmw, lswi/stswi, lswx/stswx, lq/stq, and l[bhwdq]arx/st[bhwdq]cx.

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.
