2018-03-27sfc: replace asynchronous filter operationsEdward Cree
Instead of having an efx->type->filter_rfs_insert() method, just use workitems with a worker function that calls efx->type->filter_insert(). The only user of this is efx_filter_rfs(), which now queues a call to efx_filter_rfs_work(). Similarly, efx_filter_rfs_expire() is now a worker function called on a new channel->filter_work work_struct, so the method efx->type->filter_rfs_expire_one() is no longer called in atomic context. We also add a new mutex efx->rps_mutex to protect the RPS state (efx-> rps_expire_channel, efx->rps_expire_index, and channel->rps_flow_id) so that the taking of efx->filter_lock can be moved to efx->type->filter_rfs_expire_one(). Thus, all filter table functions are now called in a sleepable context, allowing them to use sleeping locks in a future patch.

2018-03-27qede: Fix barrier usage after tx doorbell write.Manish Chopra
Since commit c5ad119fb6c09b0297446be05bd66602fa564758 ("net: sched: pfifo_fast use skb_array") driver is exposed to an issue where it is hitting NULL skbs while handling TX completions. Driver uses mmiowb() to flush the writes to the doorbell bar which is a write-combined bar, however on x86 mmiowb() does not flush the write combined buffer. This patch fixes this problem by replacing mmiowb() with wmb() after the write combined doorbell write so that writes are flushed and synchronized from more than one processor.

2018-03-27vhost: correctly remove wait queue during poll failureJason Wang
We tried to remove vq poll from wait queue, but do not check whether or not it was in a list before. This will lead double free. Fixing this by switching to use vhost_poll_stop() which zeros poll->wqh after removing poll from waitqueue to make sure it won't be freed twice.

2018-03-27parisc/pci: Switch LBA PCI bus from Hard Fail to Soft Fail modeHelge Deller
Carlo Pisani noticed that his C3600 workstation behaved unstable during heavy I/O on the PCI bus with a VIA VT6421 IDE/SATA PCI card. To avoid such instability, this patch switches the LBA PCI bus from Hard Fail mode into Soft Fail mode. In this mode the bus will return -1UL for timed out MMIO transactions, which is exactly how the x86 (and most other architectures) PCI busses behave. This patch is based on a proposal by Grant Grundler and Kyle McMartin 10 years ago: https://www.spinics.net/lists/linux-parisc/msg01027.html Cc: Carlo Pisani <carlojpisani@gmail.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Reviewed-by: Grant Grundler <grantgrundler@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>

2018-03-27net/mlx4_en: Fix mixed PFC and Global pause user control requestsEran Ben Elisha
Global pause and PFC configuration should be mutually exclusive (i.e. only one of them at most can be set). However, once PFC was turned off, driver automatically turned Global pause on. This is a bug. Fix the driver behaviour to turn off PFC/Global once the user turned the other on. This also fixed a weird behaviour that at a current time, the profile had both PFC and global pause configuration turned on, which is Hardware-wise impossible and caused returning false positive indication to query tools. In addition, fix error code when setting global pause or PFC to change metadata only upon successful change. Also, removed useless debug print.

2018-03-27r8169: fix setting driver_data after register_netdevHeiner Kallweit
pci_set_drvdata() is called only after registering the net_device, therefore we could run into a NPE if one of the functions using driver_data is called before it's set. Fix this by calling pci_set_drvdata() before registering the net_device. This fix is a candidate for stable. As far as I can see the bug has been there in kernel version 3.2 already, therefore I can't provide a reference which commit is fixed by it. The fix may need small adjustments per kernel version because due to other changes the label which is jumped to if register_netdev() fails has changed over time.

Some helper functions that search for given entries in the TCAM filter on PPv2 controller make use of dynamically alloced temporary variables, allocated with GFP_KERNEL. These functions can be called in atomic context, and dynamic alloc is not really needed in these cases anyways. This commit gets rid of dynamic allocs and use stack allocation in the following functions, and where they're used : - mvpp2_prs_flow_find - mvpp2_prs_vlan_find - mvpp2_prs_double_vlan_find - mvpp2_prs_mac_da_range_find For all these functions, instead of returning an temporary object representing the TCAM entry, we simply return the TCAM id that matches the requested entry.

2018-03-27net: mvpp2: Make mvpp2_prs_hw_read a parser entry init functionMaxime Chevallier
The mvpp2_prs_hw_read function uses the 'index' field of the struct mvpp2_prs_entry to initialize the rest of the fields. This makes it unclear from a caller's perspective, who needs to manipulate a struct that is not entirely initialized. This commit makes it an init function for prs_entry, by passing it the index as a parameter. The function now zeroes the entry, and sets the index field before doing all other init from HW. The function is renamed 'mvpp2_prs_init_from_hw' to make that clear. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Jake provides several patches which remove the need for cmpxchg64(), starting with moving I40E_FLAG_[UDP]_FILTER_SYNC from pf->flags to pf->state since they are modified during run time possibly when the RTNL lock is not held so they should be a state bits and not flags. Moved additional "flags" which should be state fields, into pf->state. Ensure we hold the RTNL lock for the entire sequence of preparing for reset and when resuming, which will protect the flags related to interrupt scheme under RTNL lock so that their modification is properly threaded. Finally, cleanup the use of cmpxchg64() since it is no longer needed. Cleaned up the holes in the feature flags created my moving some flags to the state field.

2018-03-27pinctrl: sunxi: add support for the Allwinner H6 main pin controllerIcenowy Zheng
The Allwinner H6 SoC has two pin controllers, one main controller (called CPUX-PORT in user manual) and one controller in CPUs power domain (called CPUS-PORT in user manual). This commit introduces support for the main pin controller on H6. The pin bank A and B are not wired out and hidden from the SoC's documents, however it's shown that the "ATE" (an AC200 chip co-packaged with the H6 die) is connected to the main SoC die via these pin banks. The information about these banks is just copied from the BSP pinctrl driver, but re-formatted to fit the mainline pinctrl driver format. The GPIO functions are dropped, as they're impossible to use -- except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

2018-03-27brcmsmac: allocate ucode with GFP_KERNELTakashi Iwai
The brcms_ucode_init_buf() duplicates the ucode chunks via kmemdup() with GFP_ATOMIC as a precondition of wl->lock acquired. This caused allocation failures sometimes as reported in the bugzilla below. When looking at the the real usage, one can find that it's called solely from brcms_request_fw(), and it's obviously outside the lock. Hence we can use GFP_KERNEL there safely for avoiding such allocation errors.
