sb_edac sometimes reports the wrong DIMM for a memory error found by the patrol scrubber. That is because the hardware provides only a 4KB page-aligned address for the error case. This means that the EDAC driver will point at the DIMM matching offset 0x0 in the 4KB page, but because of interleaving across channels and ranks, the actual DIMM involved may be different if the error is on some other cache line within the page. Therefore, reconstruct the socket/iMC/channel information from the "mce" structure passed to the EDAC driver. The DIMM cannot be determined, so pass "dimm=-1" to the EDAC core. It will report that all the DIMMs on that channel may be affected.

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.
