We have support for the new SMCA MCA_DE{STAT,ADDR} registers in Linux. So we've used these registers in place of MCA_{STATUS,ADDR} on SMCA systems. However, the guidance for current SMCA implementations of is to continue using MCA_{STATUS,ADDR} and to use MCA_DE{STAT,ADDR} only if a Deferred error was not found in the former registers. If we logged a Deferred error in MCA_STATUS then we should also clear MCA_DESTAT. This also means we shouldn't clear MCA_CONFIG[LogDeferredInMcaStat]. Rework __log_error() to only log an error and add helpers for the different error types being logged from the corresponding interrupt handlers. Boris: carve out common functionality into a _log_error_bank(). Cleanup comments, check MCi_STATUS bits before reading MSRs. Streamline flow.

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.
