2011-11-01EDAC: Fix incorrect edac mode reporting in sb_edacMark A. Grondona1-3/+4
The edac driver for Sandy Bridge was found to be reporting "FPM" for edac_mode, which clearly doesn't make sense. It was found that sb_edac.c:get_dimm_config was reusing a variable for both mem_type and edac_type, and thus was overwriting the value after setting it correctly. This patch fixes that issue.

2011-11-01edac: Add an experimental new driver to support Sandy Bridge CPU'sMauro Carvalho Chehab1-0/+1894
This driver is known to work on mine and Tony's test environments, using software error injection, and a partial hardware/software error injection tool. There's no broader range test yet to double check if the error decoding logic will actually point to the right DIMM, so use it with care. More tests are required to be sure that the driver will work on all different types of memory configurations. If you're willing to risk using it, I suggest you to enable EDAC debugs for your test machines, as the debug logs helps to track what's going inside the driver. Please feed me with bug reports, if you notice that the driver is miss-behaving. Tested-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Nehalem-EX uses a different memory controller. However, as the memory controller is not visible on some Nehalem/Nehalem-EP, we need to indirectly probe via a X58 PCI device. The same devices are found on (some) Nehalem-EX. So, on those machines, the probe routine needs to return -ENODEV, as the actual Memory Controller registers won't be detected.

2011-05-25x86: remove 32-bit versions of readq()/writeq()Roland Dreier1-0/+13
The presense of a writeq() implementation on 32-bit x86 that splits the 64-bit write into two 32-bit writes turns out to break the mpt2sas driver (and in general is risky for drivers as was discussed in <http://lkml.kernel.org/r/adaab6c1h7c.fsf@cisco.com>). To fix this, revert 2c5643b1c5c7 ("x86: provide readq()/writeq() on 32-bit too") and follow-on cleanups. This unfortunately leads to pushing non-atomic definitions of readq() and write() to various x86-only drivers that in the meantime started using the definitions in the x86 version of <asm/io.h>. However as discussed exhaustively, this is actually the right thing to do, because the right way to split a 64-bit transaction is hardware dependent and therefore belongs in the hardware driver (eg mpt2sas needs a spinlock to make sure no other accesses occur in between the two halves of the access). Build tested on 32- and 64-bit x86 allmodconfig.

2011-05-18drivercore: revert addition of of_match to struct deviceGrant Likely1-1/+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>

2011-04-04edac/mpc85xx: Limit setting/clearing of HID1[RFXE] to e500v1/v2 coresKumar Gala1-8/+19
Only the e500v1/v2 cores have HID1[RXFE] so we should attempt to set or clear this register bit on them. Otherwise we get crashes like: NIP: c0579f84 LR: c006d550 CTR: c0579f84 REGS: ef857ec0 TRAP: 0700 Not tainted (2.6.38.2-00072-gf15ba3c) MSR: 00021002 <ME,CE> CR: 22044022 XER: 00000000 TASK = ef8559c0[1] 'swapper' THREAD: ef856000 CPU: 0 GPR00: c006d538 ef857f70 ef8559c0 00000000 00000004 00000000 00000000 00000000 GPR08: c0590000 c30170a8 00000000 c30170a8 00000001 0fffe000 00000000 00000000 GPR16: 00000000 7ffa0e60 00000000 00000000 7ffb0bd8 7ff3b844 c05be000 00000000 GPR24: 00000000 00000000 c05c28b0 c0579fac 00000000 00029002 00000000 c0579f84 NIP [c0579f84] mpc85xx_mc_clear_rfxe+0x0/0x28 LR [c006d550] on_each_cpu+0x34/0x50 Call Trace: [ef857f70] [c006d538] on_each_cpu+0x1c/0x50 (unreliable) [ef857f90] [c057a070] mpc85xx_mc_init+0xc4/0xdc [ef857fa0] [c0001cd4] do_one_initcall+0x34/0x1a8 [ef857fd0] [c055d9d8] kernel_init+0x17c/0x218 [ef857ff0] [c000cda4] kernel_thread+0x4c/0x68 Instruction dump: 40be0018 3c60c052 3863c70c 4be9baad 3be0ffed 4bd7c99d 80010014 7fe3fb78 83e1000c 38210010 7c0803a6 4e800020 <7c11faa6> 54290024 81290008 3d60c06e Oops: Exception in kernel mode, sig: 4 [#2] ---[ end trace 49ff3b8f93efde1a ]--- Also use the HID1_RFXE define rather than a magic number.
