2010-08-03edac, mc: Improve scrub rate handlingBorislav Petkov
Fortify the interface to not accept negative values, remove memctrl_int_store() as a result. Also, sanitize bandwidth setting by making the argument a simple u32 instead of strange u32 pointer being passed around for no obvious reason. Then, fix error handling and teach it to return proper error values. Finally, make code more readable, simplify debug messages.

Since commit 5753c082f66eca5be81f6bda85c1718c5eea6ada ("powerpc/85xx: Kconfig cleanup"), there is no MPC85xx Kconfig symbol anymore, so the driver became non-selectable.

2010-07-02i7core_edac: Avoid doing multiple probes for the same cardMauro Carvalho Chehab
As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same functionality (memory controller), the default way of proping devices doesn't work. So, instead of a per-device probe, all devices should be probed at once. This means that we should block any new attempt of probe, otherwise, it will try to register the same device several times.

2010-07-02i7core_edac: Properly discover the first QPI deviceMauro Carvalho Chehab
On Nehalem/Nehalem-EP/Westmere, the first QPI device is the last PCI bus. The last bus is generally at 0x3f or 0xff, but there are also other systems using different setups. For example, HP Z800 has 0x7f as the last bus. This patch adds a logic to discover the last bus, dynamically detecting it at runtime.

2010-07-02amd64_edac: Fix syndrome calculation on K8Borislav Petkov
When calculating the DCT channel from the syndrome we need to know the syndrome type (x4 vs x8). On F10h, this is read out from extended PCI cfg space register F3x180 while on K8 we only support x4 syndromes and don't have extended PCI config space anyway. Make the code accessing F3x180 F10h only and fall back to x4 syndromes on everything else.

2010-05-22of: Remove duplicate fields from of_platform_driverGrant Likely
.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

2010-05-18Always call i7core_[ur]dimm_check_mc_ecc_errVernon Mauery
This fixes an error in function i7core_check_error In commit ca9c90ba09ca3c9799319f46a56f397afbf617c2 which converts the driver to use double buffering, there is a change in the logic. Before, if mce_count was zero, it skipped over a couple of statements and finished out with a call to the *check_mc_ecc_err function. The current code checks to see if mce_count is 0 and then exits. This change reverts the behavior back to the original where if there are no errors to report, we skip to the end and call the *check_mc_ecc_err function. This fix allows the driver to work again on my Nehalem based blades again. Signed-off-by: Vernon Mauery <vernux@us.ibm.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
