Jan Moskyto Matejka authored
The sum at the beginning of line "intr" includes also unnumbered interrupts. It implies that the sum at the beginning isn't the sum of the remainder of the line, not even an estimation. Fixed the documentation to mention that. This behaviour was added to /proc/stat in commit a2eddfa9 ("x86: make /proc/stat account for all interrupts") Signed-off-by: Jan Moskyto Matejka <mq@suse.cz> Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The mapping from OF device IDs to platform device IDs is wrong. TYPE_NCPXXWB473 is 0, TYPE_NCPXXWL333 is 1, so ntc_thermistor_id[TYPE_NCPXXWB473] is { "ncp15wb473", TYPE_NCPXXWB473 } while ntc_thermistor_id[TYPE_NCPXXWL333] is { "ncp18wb473", TYPE_NCPXXWB473 }. So the name is wrong for all but the "ntc,ncp15wb473" entry, and the type is wrong for the "ntc,ncp15wl333" entry. So map the entries by index, it is neither elegant nor robust but at least it is correct.

Jean Delvare authored
In commit 9e8269de, support was added for ntc_thermistor devices being declared in the device tree and implemented on top of IIO. With that change, a dependency was added to the ntc_thermistor driver: depends on (!OF && !IIO) || (OF && IIO) This construct has the drawback that the driver can no longer be selected when OF is set and IIO isn't, nor when IIO is set and OF is not. This is a regression for the original users of the driver. As the new code depends on IIO and is useless without OF, include it only if both are enabled, and set the dependencies accordingly. This is clearer, more simple and more correct.

The temp[1-*]_min_hyst sysfs attribute is already implemented by 3 hwmon drivers (adt7x10, lm77 and lm92) but was missing from the standard interface. Also add temp[1-*]_lcrit_hyst for consistency, even though no driver implement that one for the time being.

Naoya Horiguchi authored
When a memory error happens on an in-use page or (free and in-use) hugepage, the victim page is isolated with its refcount set to one. When you try to unpoison it later, unpoison_memory() calls put_page() for it twice in order to bring the page back to free page pool (buddy or free hugepage list). However, if another memory error occurs on the page which we are unpoisoning, memory_failure() returns without releasing the refcount which was incremented in the same call at first, which results in memory leak and unconsistent num_poisoned_pages statistics. This patch fixes it.

Commit 284f39af ("mm: memcg: push !mm handling out to page cache charge function") explicitly checks for page cache charges without any mm context (from kernel thread context[1]). This seemed to be the only possible case where memory could be charged without mm context so commit 03583f1a ("memcg: remove unnecessary !mm check from try_get_mem_cgroup_from_mm()") removed the mm check from get_mem_cgroup_from_mm(). This however caused another NULL ptr dereference during early boot when loopback kernel thread splices to tmpfs as reported by Stephan Kulow: BUG: unable to handle kernel NULL pointer dereference at 0000000000000360 IP: get_mem_cgroup_from_mm.isra.42+0x2b/0x60 Oops: 0000 [#1] SMP Modules linked in: btrfs dm_multipath dm_mod scsi_dh multipath raid10 raid456 async_raid6_recov async_memcpy async_pq raid6_pq async_xor xor async_tx raid1 raid0 md_mod parport_pc parport nls_utf8 isofs usb_storage iscsi_ibft iscsi_boot_sysfs arc4 ecb fan thermal nfs lockd fscache nls_iso8859_1 nls_cp437 sg st hid_generic usbhid af_packet sunrpc sr_mod cdrom ata_generic uhci_hcd virtio_net virtio_blk ehci_hcd usbcore ata_piix floppy processor button usb_common virtio_pci virtio_ring virtio edd squashfs loop ppa] CPU: 0 PID: 97 Comm: loop1 Not tainted 3.15.0-rc5-5-default #1 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Call Trace: __mem_cgroup_try_charge_swapin+0x40/0xe0 mem_cgroup_charge_file+0x8b/0xd0 shmem_getpage_gfp+0x66b/0x7b0 shmem_file_splice_read+0x18f/0x430 splice_direct_to_actor+0xa2/0x1c0 do_lo_receive+0x5a/0x60 [loop] loop_thread+0x298/0x720 [loop] kthread+0xc6/0xe0 ret_from_fork+0x7c/0xb0 Also Branimir Maksimovic reported the following oops which is tiggered for the swapcache charge path from the accounting code for kernel threads: CPU: 1 PID: 160 Comm: kworker/u8:5 Tainted: P OE 3.15.0-rc5-core2-custom #159 Hardware name: System manufacturer System Product Name/MAXIMUSV GENE, BIOS 1903 08/19/2013 task: ffff880404e349b0 ti: ffff88040486a000 task.ti: ffff88040486a000 RIP: get_mem_cgroup_from_mm.isra.42+0x2b/0x60 Call Trace: __mem_cgroup_try_charge_swapin+0x45/0xf0 mem_cgroup_charge_file+0x9c/0xe0 shmem_getpage_gfp+0x62c/0x770 shmem_write_begin+0x38/0x40 generic_perform_write+0xc5/0x1c0 __generic_file_aio_write+0x1d1/0x3f0 generic_file_aio_write+0x4f/0xc0 do_sync_write+0x5a/0x90 do_acct_process+0x4b1/0x550 acct_process+0x6d/0xa0 do_exit+0x827/0xa70 kthread+0xc3/0xf0 This patch fixes the issue by reintroducing mm check into get_mem_cgroup_from_mm. We could do the same trick in __mem_cgroup_try_charge_swapin as we do for the regular page cache path but it is not worth troubles. The check is not that expensive and it is better to have get_mem_cgroup_from_mm more robust.

In some testing I ran today (some fio jobs that spread over two nodes), we end up spending 40% of the time in filemap_check_errors(). That smells fishy. Looking further, this is basically what happens: blkdev_aio_read() generic_file_aio_read() filemap_write_and_wait_range() if (!mapping->nr_pages) filemap_check_errors() and filemap_check_errors() always attempts two test_and_clear_bit() on the mapping flags, thus dirtying it for every single invocation. The patch below tests each of these bits before clearing them, avoiding this issue. In my test case (4-socket box), performance went from 1.7M IOPS to 4.0M IOPS.

The recent change in sysfs, bcdde7e2 "sysfs: make __sysfs_remove_dir() recursive" revealed an asymmetric rphy device creation/deletion sequence in scsi_transport_sas: modprobe mpt2sas sas_rphy_add device_add A rphy->dev device_add B sas_device transport class device_add C sas_end_device transport class device_add D bsg class rmmod mpt2sas sas_rphy_delete sas_rphy_remove device_del B device_del C device_del A sysfs_remove_group recursive sysfs dir removal sas_rphy_free device_del D warning where device A is the parent of B, C, and D. When sas_rphy_free tries to unregister the bsg request queue (device D above), the ensuing sysfs cleanup discovers that its sysfs group has already been removed and emits a warning, "sysfs group... not found for kobject 'end_device-X:0'". Since bsg creation is a side effect of sas_rphy_add, move its complementary removal call into sas_rphy_remove. This imposes the following tear-down order for the devices above: D, B, C, A. Note the sas_device and sas_end_device transport class devices (B and C above) are created and destroyed both via the list match traversal in attribute_container_device_trigger, so the order in which they are handled is fixed. This is fine as long as they are deleted before their parent device.

ALB learning packets are currentlyalways sent using the slave mac address for all vlans configured on top of bond. This is not always correct, as vlans may change their mac address. This patch introduced a concept of strict matching where the source of learning packets can either strictly match the address passed in, or it can determine a more correct address to use. There are 3 casese to consider: 1) Switchover. In this case, we have a new active slave and we need tell the switch about all addresses available on the slave. 2) Monitor. We'll periodically refresh learning info for all slaves. In this case, we refresh all addresses for current active, and just the slave address for other slaves. 3) Teaching of disabled adddress. This happens as part of the failover and in this case, we alwyas to use just the address provided.

TLB/ALB learning packets always assume 802.1Q vlan protocol, but that is no longer the case since we now have support for Q-in-Q on top of bonding. Pass the vlan protocol to alb_send_lp_vid() so that the packets are properly tagged.

The stmmac_open call was calling clk_disable_unprepare on phy init failure, but it never calls clk_prepare_enable, this causes a WARN_ON in the clk framework to trigger if for some reason phy init fails.

When GRE support was added in linux-3.14, CHECKSUM_COMPLETE handling broke on GRE+IPv6 because we did not update/use the appropriate csum : GRO layer is supposed to use/update NAPI_GRO_CB(skb)->csum instead of skb->csum Tested using a GRE tunnel and IPv6 traffic. GRO aggregation now happens at the first level (ethernet device) instead of being done in gre tunnel. Native IPv6+TCP is still properly aggregated.
