Previously, the area between 0x0-0x100 have been used as a "scratch" memory area to temporarily store regs during exception entry. In a multi-core environment, this will not work. This change is to use shadow registers for nested context. Currently only the "critical" temp load/stores are covered, the EMERGENCY_PRINT ones are left as is (when they are used, it's game over anyway), they need to be handled as well in the future.

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.
