2012-07-03dm persistent data: fix allocation failure in space map checker initMike Snitzer1-11/+19
If CONFIG_DM_DEBUG_SPACE_MAPS is enabled and memory is fragmented and a sufficiently-large metadata device is used in a thin pool then the space map checker will fail to allocate the memory it requires. Switch from kmalloc to vmalloc to allow larger virtually contiguous allocations for the space map checker's internal count arrays.

2012-07-03dm thin: commit metadata before creating metadata snapshotJoe Thornber1-0/+7
Userland sometimes sees a corrupt metadata block if metadata is changing rapidly when a metadata snapshot is reserved for userland, To make the problem go away, commit before we take the metadata snapshot (which is a sensible thing to do anyway). The checksums mean userland spots this corruption immediately so there's no risk of acting on incorrect data. No corruption exists from the kernel's point of view, and thin_check passes after pool shutdown. I believe this is to do with shared blocks at the first level of the {device, mapping} btree. Prior to the metadata-snap support no sharing at this level was possible, so this patch is only required after commit cc8394d86f045b86ff303d3c9e4ce47d97148951 ("dm thin: provide userspace access to pool metadata").

2012-07-03drm/i915: kick any firmware framebuffers before claiming the gttDaniel Vetter1-7/+30
Especially vesafb likes to map everything as uc- (yikes), and if that mapping hangs around still while we try to map the gtt as wc the kernel will downgrade our request to uc-, resulting in abyssal performance. Unfortunately we can't do this as early as readon does (i.e. as the first thing we do when initializing the hw) because our fb/mmio space region moves around on a per-gen basis. So I've had to move it below the gtt initialization, but that seems to work, too. The important thing is that we do this before we set up the gtt wc mapping. Now an altogether different question is why people compile their kernels with vesafb enabled, but I guess making things just work isn't bad per se ... v2: - s/radeondrmfb/inteldrmfb/ - fix up error handling v3: Kill #ifdef X86, this is Intel after all. Noticed by Ben Widawsky. v4: Jani Nikula complained about the pointless bool primary initialization. v5: Don't oops if we can't allocate, noticed by Chris Wilson. v6: Resolve conflicts with agp rework and fixup whitespace. This is commit e188719a2891f01b3100d in drm-next. Backport to 3.5 -fixes queue requested by Dave Airlie - due to grub using vesa on fedora their initrd seems to load vesafb before loading the real kms driver. So tons more people actually experience a dead-slow gpu. Hence also the Cc: stable.

2012-07-03drm: edid: Don't add inferred modes with higher resolutionTakashi Iwai1-3/+24
When a monitor EDID doesn't give the preferred bit, driver assumes that the mode with the higest resolution and rate is the preferred mode. Meanwhile the recent changes for allowing more modes in the GFT/CVT ranges give actually more modes, and some modes may be over the native size. Thus such a mode would be picked up as the preferred mode although it's no native resolution. For avoiding such a problem, this patch limits the addition of inferred modes by checking not to be greater than other modes. Also, it checks the duplicated mode entry at the same time.

2012-07-03md: fix up plugging (again).NeilBrown3-16/+9
The value returned by "mddev_check_plug" is only valid until the next 'schedule' as that will unplug things. This could happen at any call to mempool_alloc. So just calling mddev_check_plug at the start doesn't really make sense. So call it just before, or just after, queuing things for the thread. As the action that happens at unplug is to wake the thread, this makes lots of sense. If we cannot add a plug (which requires a small GFP_ATOMIC alloc) we wake thread immediately. RAID5 is a bit different. Requests are queued for the thread and the thread is woken by release_stripe. So we don't need to wake the thread on failure. However the thread doesn't perform certain actions when there is any active plug, so it is important to install a plug before waking the thread. So for RAID5 we install the plug *before* queuing the request and waking the thread. Without this patch it is possible for raid1 or raid10 to queue a request without then waking the thread, resulting in the array locking up. Also change raid10 to only flush_pending_write when there are not active plugs, just like raid1. This patch is suitable for 3.0 or later. I plan to submit it to -stable, but I'll like to let it spend a few weeks in mainline first to be sure it is completely safe. Signed-off-by: NeilBrown <neilb@suse.de>
2012-07-03can: flexcan: add hardware controller version supportHui Wang1-8/+52
At least in the i.MX series, the flexcan contrller divides into ver_3 and ver_10, current driver is for ver_3 controller. i.MX6 has ver_10 controller, it has more reigsters than ver_3 has. The rxfgmask (Rx FIFO Global Mask) register is one of the new added. Its reset value is 0xffffffff, this means ID Filter Table must be checked when receive a packet, but the driver is designed to accept everything during the chip start, we need to clear this register to follow this design. Use the data entry of the struct of_device_id to point chip specific info, we can set hardware version for each platform.

2012-07-03md: support re-add of recovering devices.NeilBrown1-2/+1
We currently only allow a device to be re-added if it appear to be in-sync. This is overly restrictive as it may be desirable to re-add a device that is in the middle of recovery. So remove the test for "InSync" - the test on rdev->raid_disk is sufficient to ensure that the re-add will succeed.

When we added hot_replace we doubled the number of devices that could be in a RAID1 array. So we doubled how far read_balance would search. Unfortunately we didn't double the point at which it looped back to the beginning - so it effectively loops over all non-replacement disks twice. This doesn't cause bad behaviour, but it pointless and means we never read from replacement devices. Signed-off-by: NeilBrown <neilb@suse.de>

A delayed stripe can be moved to hold list only when preread active stripe count is below IO_THRESHOLD. If a stripe has both the bits set, such stripe will be in delayed list and preread count not 0, which will make such stripe never leave delayed list.

We don't store data there, but when recovering the last device in an array we retry to recover that last chunk from a non-existent location. This results in an error, and the recovery aborts. When we get to that last chunk we should just stop - there is nothing more to do anyway.

2012-07-01phy: add the EEE support and the way to access to the MMD registers.Giuseppe CAVALLARO1-0/+281
This patch adds the support for the Energy-Efficient Ethernet (EEE) to the Physical Abstraction Layer. To support the EEE we have to access to the MMD registers 3.20 and 7.60/61. So two new functions have been added to read/write the MMD registers (clause 45). An Ethernet driver (I tested the stmmac) can invoke the phy_init_eee to properly check if the EEE is supported by the PHYs and it can also set the clock stop enable bit in the 3.0 register. The phy_get_eee_err can be used for reporting the number of time where the PHY failed to complete its normal wake sequence. In the end, this patch also adds the EEE ethtool support implementing: o phy_ethtool_set_eee o phy_ethtool_get_eee v1: initial patch v2: fixed some errors especially on naming convention v3: renamed again the mmd read/write functions thank to Ben's feedback v4: moved file to phy.c and added the ethtool support. v5: fixed phy_adv_to_eee, phy_eee_to_supported, phy_eee_to_adv return values according to ethtool API (thanks to Ben's feedback). Renamed some macros to avoid too long names. v6: fixed kernel-doc comments to be properly parsed. Fixed the phy_init_eee function: we need to check which link mode was autonegotiated and then the corresponding bits in 7.60 and 7.61 registers. v7: reviewed the way to get the negotiated settings. v8: fixed a problem in the phy_init_eee return value erroneously added when included the phy_read_status call. v9: do not remove the MDIO_AN_EEE_ADV_100TX and MDIO_AN_EEE_ADV_1000T and fixed the eee_{cap,lp,adv} declaration as "int" instead of u16.

Thanks also goes to Rayagond Kokatanur for his first implementation.

2012-07-01e1000e: remove use of IP payload checksumBruce Allan2-61/+15
Currently only used when packet split mode is enabled with jumbo frames, IP payload checksum (for fragmented UDP packets) is mutually exclusive with receive hashing offload since the hardware uses the same space in the receive descriptor for the hardware-provided packet checksum and the RSS hash, respectively. Users currently must disable jumbos when receive hashing offload is enabled, or vice versa, because of this incompatibility. Since testing has shown that IP payload checksum does not provide any real benefit, just remove it so that there is no longer a choice between jumbos or receive hashing offload but not both as done in other Intel GbE drivers (e.g. e1000, igb). Also, add a missing check for IP checksum error reported by the hardware; let the stack verify the checksum when this happens.

2012-06-30acpi_pad: fix power_saving thread deadlockStuart Hayes1-3/+4
The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>
2012-06-30ACPI video: Still use ACPI backlight control if _DOS doesn't existZhang Rui1-0/+2
This fixes a regression in 3.4-rc1 caused by commit ea9f8856bd6d4ed45885b06a338f7362cd6c60e5 (ACPI video: Harden video bus adding.) Some platforms don't have _DOS control method, but the ACPI backlight still works. We should not invoke _DOS for these platforms. https://bugzilla.kernel.org/show_bug.cgi?id=43168 Cc: Igor Murzov <intergalactic.anonymous@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2012-06-29netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso5-13/+29
This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

John Linville says: ==================== Here is another batch of updates intended for 3.6. This includes a number of pulls, including ones from the mac80211, iwlwifi, ath6kl, and wl12xx trees. I also pulled from the wireless tree to avoid potential build conflicts. There are a number of other patches applied directly, including a number for the Broadcom drivers and the mwifiex driver. The updates cover the usual variety of new hardware support and feature enhancements. It's all good work, but there aren't any big headliners. This does resolve a net-next/wireless-next merge conflict reported by Stephen. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-29drm/radeon: fix VM page table setup on SIAlex Deucher2-4/+13
Cayman and trinity allow for variable sized VM page tables, but SI requires that all page tables be the same size. The current code assumes variablely sized VM page tables so SI may end up with part of each page table overlapping with other memory which could end up being interpreted by the VM hw as garbage. Change the code to better accomodate SI. Allocate enough space for at least 2 full page tables and always set last_pfn to max_pfn on SI so each VM is backed by a full page table. This limits us to only 2 VMs active at any given time on SI. This will be rectified and the code can be reunified once we move to two level page tables.

2012-06-29xen/netback: only non-freed SKB is queued into tx_queueAnnie Li1-2/+2
After SKB is queued into tx_queue, it will be freed if request_gop is NULL. However, no dequeue action is called in this situation, it is likely that tx_queue constains freed SKB. This patch should fix this issue, and it is based on 3.5.0-rc4+. This issue is found through code inspection, no bug is seen with it currently. I run netperf test for several hours, and no network regression was found. Signed-off-by: Annie Li <annie.li@oracle.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: David S.
