Users of the mce_register_decode_chain() are called for every logged error. EDAC drivers should check: 1) Is this a memory error? [bit 7 in status register] 2) Is there a valid address? [bit 58 in status register] 3) Is the address a system address? [bitfield 8:6 in misc register] The sb_edac driver performed test "1" twice. Waited far too long to perform check "2". Didn't do check "3" at all. Fix it by moving the test for valid address from sbridge_mce_output_error() into sbridge_mce_check_error() and add a test for the type immediately after. Delete the redundant check for the type of the error from sbridge_mce_output_error().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
