2012-12-12MIPS: Cavium: Add EDAC support.Ralf Baechle
Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

Pgtable bits are assigned dynamically depending on processor feature and statically based on kernel configuration. To make sense out of the disassembled TLB exception handlers a list of the actual assignments used for a particular configuration and hardware setup can be very useful.

Pull MIPS fixes from Ralf Baechle: "Three issues fixed accross the field: - Some functions that were recently outlined as part of a preemption fix were causing problems with function tracing. - The recently merged in-kernel MPI library uses very outdated headers that contain MIPS-specific code which won't build on with gcc 4.4 or newer. - The MIPS non-NUMA memory initialization was making only a very half-baked attempt at merging adjacent memory ranges.

2012-11-26powerpc/eeh: Do not invalidate PE properlyGavin Shan
While the EEH does recovery on the specific PE that has PCI errors, the PCI devices belonging to the PE will be removed and the PE will be marked as invalid since we still need the information stored in the PE. We only invalidate the PE when it doesn't have associated EEH devices and valid child PEs. However, the code used to check that is wrong. The patch fixes that.

2012-11-23of/address: sparc: Declare of_iomap as an extern function for sparc againAndreas Larsson
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

2012-11-23PM / QoS: fix wrong error-checking conditionGuennadi Liakhovetski
dev_pm_qos_add_request() can return 0, 1, or a negative error code, therefore the correct error test is "if (error < 0)." Checking just for non-zero return code leads to erroneous setting of the req->dev pointer to NULL, which then leads to a repeated call to dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn leads to an Oops, when the I2C host adapter is unloaded and reloaded again because of the inconsistent state of its QoS request list.

2012-11-23block: Don't access request after it might be freedRoland Dreier
After we've done __elv_add_request() and __blk_run_queue() in blk_execute_rq_nowait(), the request might finish and be freed immediately. Therefore checking if the type is REQ_TYPE_PM_RESUME isn't safe afterwards, because if it isn't, rq might be gone. Instead, check beforehand and stash the result in a temporary. This fixes crashes in blk_execute_rq_nowait() I get occasionally when running with lots of memory debugging options enabled -- I think this race is usually harmless because the window for rq to be reallocated is so small.

2012-11-23floppy: destroy floppy workqueue before cleaning up the queueJiri Kosina
We need to first destroy the floppy_wq workqueue before cleaning up the queue. Otherwise we might race with still pending work with the workqueue, but all the block queue already gone. This might lead to various oopses, such as CPU 0 Pid: 6, comm: kworker/u:0 Not tainted 3.7.0-rc4 #1 Bochs Bochs RIP: 0010:[<ffffffff8134eef5>] [<ffffffff8134eef5>] blk_peek_request+0xd5/0x1c0 RSP: 0000:ffff88000dc7dd88 EFLAGS: 00010092 RAX: 0000000000000001 RBX: 0000000000000000 RCX: 0000000000000000 RDX: ffff88000f602688 RSI: ffffffff81fd95d8 RDI: 6b6b6b6b6b6b6b6b RBP: ffff88000dc7dd98 R08: ffffffff81fd95c8 R09: 0000000000000000 R10: ffffffff81fd9480 R11: 0000000000000001 R12: 6b6b6b6b6b6b6b6b R13: ffff88000dc7dfd8 R14: ffff88000dc7dfd8 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffffffff81e21000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000000 CR3: 0000000001e11000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kworker/u:0 (pid: 6, threadinfo ffff88000dc7c000, task ffff88000dc5ecc0) Stack: 0000000000000000 0000000000000000 ffff88000dc7ddb8 ffffffff8134efee ffff88000dc7ddb8 0000000000000000 ffff88000dc7dde8 ffffffff814aef3c ffffffff81e75d80 ffff88000dc0c640 ffff88000fbfb000 ffffffff814aed90 Call Trace: [<ffffffff8134efee>] blk_fetch_request+0xe/0x30 [<ffffffff814aef3c>] redo_fd_request+0x1ac/0x400 [<ffffffff814aed90>] ? start_motor+0x130/0x130 [<ffffffff8106b526>] process_one_work+0x136/0x450 [<ffffffff8106af65>] ? manage_workers+0x205/0x2e0 [<ffffffff8106bb6d>] worker_thread+0x14d/0x420 [<ffffffff8106ba20>] ? rescuer_thread+0x1a0/0x1a0 [<ffffffff8107075a>] kthread+0xba/0xc0 [<ffffffff810706a0>] ? __kthread_parkme+0x80/0x80 [<ffffffff818b553a>] ret_from_fork+0x7a/0xb0 [<ffffffff810706a0>] ? __kthread_parkme+0x80/0x80 Code: 0f 84 c0 00 00 00 83 f8 01 0f 85 e2 00 00 00 81 4b 40 00 00 80 00 48 89 df e8 58 f8 ff ff be fb ff ff ff fe ff ff <49> 8b 1c 24 49 39 dc 0f 85 2e ff ff ff 41 0f b6 84 24 28 04 00 RIP [<ffffffff8134eef5>] blk_peek_request+0xd5/0x1c0 RSP <ffff88000dc7dd88> Reported-by: Fengguang Wu <fengguang.wu@intel.com> Tested-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2012-11-22ipv4: do not cache looped multicastsJulian Anastasov
Starting from 3.6 we cache output routes for multicasts only when using route to 224/4. For local receivers we can set RTCF_LOCAL flag depending on the membership but in such case we use maddr and saddr which are not caching keys as before. Additionally, we can not use same place to cache routes that differ in RTCF_LOCAL flag value. Fix it by caching only RTCF_MULTICAST entries without RTCF_LOCAL (send-only, no loopback). As a side effect, we avoid unneeded lookup for fnhe when not caching because multicasts are not redirected and they do not learn PMTU. Thanks to Maxime Bizon for showing the caching problems in __mkroute_output for 3.6 kernels: different RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or ip_output call and the visible problem is that traffic can not reach local receivers via loopback.
