CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

If none of the elements in scrubrates[] matches, this loop will cause __amd64_set_scrub_rate() to incorrectly use the n+1th element. As the function is designed to use the final scrubrates[] element in the case of no match, we can fix this bug by simply terminating the array search at the n-1th element.

In order to avoid loosing error events, it is desirable to group error events together and generate a single trace for several identical errors. The trace API already allows reporting multiple errors. Change the handle_error function to also allow that.

Almost all edac drivers initialize csrow_info->first_page, csrow_info->last_page and csrow_info->page_mask. Those vars are used inside the EDAC core, in order to calculate the csrow affected by an error, by using the routine edac_mc_find_csrow_by_page(). However, very few drivers actually use it: e752x_edac.c e7xxx_edac.c i3000_edac.c i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c r82600_edac.c There also a few other drivers that have their own calculus formula internally using those vars. All the others are just wasting time by initializing those data. While initializing data without using them won't cause any troubles, as those information is stored at the wrong place (at csrows structure), it is better to remove what is unused, in order to simplify the next patch.

On systems based on chip select rows, all channels need to use memories with the same properties, otherwise the memories on channels A and B won't be recognized. However, such assumption is not true for all types of memory controllers. Controllers for FB-DIMM's don't have such requirements. Also, modern Intel controllers seem to be capable of handling such differences. So, we need to get rid of storing the DIMM information into a per-csrow data, storing it, instead at the right place. The first step is to move grain, mtype, dtype and edac_mode to the per-dimm struct.

While initializing the array of csrow attribute instances, a few csrows were uninitialized. This happened because the module only performed a check for DRAM base ctl register0's and not DRAM base ctl register1's chip select enable bit. There could be systems with DIMMs populated on only single memory channel whereas the module also assumed that a dual channel dimm had double the memory size of a single memory channel instead of checking the memory on each channel.
