* drivercore: revert addition of of_match to struct deviceGrant Likely2011-05-181-1/+1
| | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* amd64_edac: Erratum #637 workaroundBorislav Petkov2011-04-262-2/+51
| | | | | | | | | F15h CPUs may report a non-DRAM address when reporting an error address belonging to a CC6 state save area. Add a workaround to detect this condition and compute the actual DRAM address of the error as documented in the Revision Guide for AMD Family 15h Models 00h-0Fh Processors.

* amd64_edac: Factor in CC6 save areaBorislav Petkov2011-04-262-1/+29
| | | | | | | | | | F15h and later use a portion of DRAM as a CC6 storage area. BIOS programs D18F1x[17C:140,7C:40] DRAM Base/Limit accordingly by subtracting the storage area from the DRAM limit setting. However, in order for edac to consider that part of DRAM too, we need to include it into the per-node range. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
* amd64_edac: Remove node interleave warningBorislav Petkov2011-04-261-5/+1
| | | | | | | | | This warning was wrongfully added for a normal condition - intlvsel actually selects the destination node when node interleaving is enabled and it is not a mismatch. For a detailed example, see section 2.8.10.2 "Node Interleaving" in F10h BKDG. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

These warnings are trivial to kill, yet rather annoying when building with -Wextra. The more we can cut down on pointless crap like this the better (IMHO).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function maps the system address to the normalized DCT address. Document what the code does for more clarity and wrap insane bitmasks in a more understandable macro which generates them. Also, reduce number of arguments passed to the function. Finally, rename this function to what it actually does. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
