Change the EDAC internal representation to work with non-csrow based memory controllers. There are lots of those memory controllers nowadays, and more are coming. So, the EDAC internal representation needs to be changed, in order to work with those memory controllers, while preserving backward compatibility with the old ones. The edac core was written with the idea that memory controllers are able to directly access csrows. This is not true for FB-DIMM and RAMBUS memory controllers. Also, some recent advanced memory controllers don't present a per-csrows view. Instead, they view memories as DIMMs, instead of ranks. So, change the allocation and error report routines to allow them to work with all types of architectures. This will allow the removal of several hacks with FB-DIMM and RAMBUS memory controllers. Also, several tests were done on different platforms using different x86 drivers. TODO: a multi-rank DIMMs are currently represented by multiple DIMM entries in struct dimm_info. That means that changing a label for one rank won't change the same label for the other ranks at the same DIMM. This bug is present since the beginning of the EDAC, so it is not a big deal. However, on several drivers, it is possible to fix this issue, but it should be a per-driver fix, as the csrow => DIMM arrangement may not be equal for all. So, don't try to fix it here yet. I tried to make this patch as short as possible, preceding it with several other patches that simplified the logic here. Yet, as the internal API changes, all drivers need changes. The changes are generally bigger in the drivers for FB-DIMMs. Cc: Aristeu Rozanski <arozansk@redhat.com> Cc: Doug Thompson <norsk5@yahoo.com> Cc: Borislav Petkov <borislav.petkov@amd.com> Cc: Mark Gross <mark.gross@intel.com> Cc: Jason Uhlenkott <juhlenko@akamai.com> Cc: Tim Small <tim@buttersideup.com> Cc: Ranganathan Desikan <ravi@jetztechnologies.com> Cc: "Arvind R." <arvino55@gmail.com> Cc: Olof Johansson <olof@lixom.net> Cc: Egor Martovetsky <egor@pasemi.com> Cc: Chris Metcalf <cmetcalf@tilera.com> Cc: Michal Marek <mmarek@suse.cz> Cc: Jiri Kosina <jkosina@suse.cz> Cc: Joe Perches <joe@perches.com> Cc: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Hitoshi Mitake <h.mitake@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: "Niklas Söderlund" <niklas.soderlund@ericsson.com> Cc: Shaohui Xie <Shaohui.Xie@freescale.com> Cc: Josh Boyer <jwboyer@gmail.com> Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The edac core were written with the idea that memory controllers are able to directly access csrows, and that the channels are used inside a csrows select. This is not true for FB-DIMM and RAMBUS memory controllers. Also, some recent advanced memory controllers don't present a per-csrows view. Instead, they view memories as DIMMs, instead of ranks, accessed via csrow/channel. So, changes are needed in order to allow the EDAC core to work with all types of architectures. In preparation for handling non-csrows based memory controllers, add some memory structs and a macro: enum hw_event_mc_err_type: describes the type of error (corrected, uncorrected, fatal) To be used by the new edac_mc_handle_error function; enum edac_mc_layer: describes the type of a given memory architecture layer (branch, channel, slot, csrow). struct edac_mc_layer: describes the properties of a memory layer (type, size, and if the layer will be used on a virtual csrow. EDAC_DIMM_PTR() - as the number of layers can vary from 1 to 3, this macro converts from an address with up to 3 layers into a linear address.

The edac_align_ptr() function is used to prepare data for a single memory allocation kzalloc() call. It counts how many bytes are needed by some data structure. Using it as-is is not that trivial, as the quantity of memory elements reserved is not there, but, instead, it is on a next call. In order to avoid mistakes when using it, move the number of allocated elements into it, making easier to use it.

The number of pages is a dimm property. Move it to the dimm struct. After this change, it is possible to add sysfs nodes for the DIMM's that will properly represent the DIMM stick properties, including its size. A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when the memory controller represents the memory via chip select rows.

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.

The way a DIMM is currently represented implies that they're linked into a per-csrow struct. However, some drivers don't see csrows, as they're ridden behind some chip like the AMB's on FBDIMM's, for example. This forced drivers to fake^Wvirtualize a csrow struct, and to create a mess under csrow/channel original's concept. Move the DIMM labels into a per-DIMM struct, and add there the real location of the socket, in terms of csrow/channel. Latter patches will modify the location to properly represent the memory architecture. All other drivers will use a per-csrow type of location. Some of those drivers will require a latter conversion, as they also fake the csrows internally. TODO: While this patch doesn't change the existing behavior, on csrows-based memory controllers, a csrow/channel pair points to a memory rank. There's a known bug at the EDAC core that allows having different labels for the same DIMM, if it has more than one rank. A latter patch is need to merge the several ranks for a DIMM into the same dimm_info struct, in order to avoid having different labels for the same DIMM. The edac_mc_alloc() will now contain a per-dimm initialization loop that will be changed by latter patches in order to match other types of memory architectures.

Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case.

Occasionally, testing memcg's move_charge_at_immigrate on rc7 shows a flurry of hundreds of warnings at kernel/res_counter.c:96, where res_counter_uncharge_locked() does WARN_ON(counter->usage < val). The first trace of each flurry implicates __mem_cgroup_cancel_charge() of mc.precharge, and an audit of mc.precharge handling points to mem_cgroup_move_charge_pte_range()'s THP handling in commit 12724850 ("memcg: avoid THP split in task migration"). Checking !mc.precharge is good everywhere else, when a single page is to be charged; but here the "mc.precharge -= HPAGE_PMD_NR" likely to follow, is liable to result in underflow (a lot can change since the precharge was estimated). Simply check against HPAGE_PMD_NR: there's probably a better alternative, trying precharge for more, splitting if unsuccessful; but this one-liner is safer for now - no kernel/res_counter.c:96 warnings seen in 26 hours.

A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree.
