AFAICS the last uses of directly 'making' kernel PGDs was removed 7 years ago: 8b78c21d72d9: ("x86, 64bit, mm: hibernate use generic mapping_init") Where the explicit PGD walking loop was replaced with kernel_ident_mapping_init() calls. This was then (unnecessarily) carried over through the 5-level paging conversion. Also clean up the 'level' comments a bit, to convey the original, meanwhile somewhat bit-rotten notion, that these are empty comment blocks with no methods to handle any of the levels except the PTE level.

2020-07-25ARM: dts: keystone-k2g-evm: fix rgmii phy-mode for ksz9031 phyGrygorii Strashko
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on keystone-k2g-evm board. The above board have phy-mode = "rgmii-id" and it is worked before because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay by default. After above commit, the KSZ9031 PHY starts handling phy mode properly and enables both RX and TX delays, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.

2020-07-24riscv: Parse all memory blocks to remove unusable memoryAtish Patra
Currently, maximum physical memory allowed is equal to -PAGE_OFFSET. That's why we remove any memory blocks spanning beyond that size. However, it is done only for memblock containing linux kernel which will not work if there are multiple memblocks. Process all memory blocks to figure out how much memory needs to be removed and remove at the end instead of updating the memblock list in place.

2020-07-24drivers/net/wan: lapb: Corrected the usage of skb_cowXie He
This patch fixed 2 issues with the usage of skb_cow in LAPB drivers "lapbether" and "hdlc_x25": 1) After skb_cow fails, kfree_skb should be called to drop a reference to the skb. But in both drivers, kfree_skb is not called. 2) skb_cow should be called before skb_push so that is can ensure the safety of skb_push. But in "lapbether", it is incorrectly called after skb_push. More details about these 2 issues: 1) The behavior of calling kfree_skb on failure is also the behavior of netif_rx, which is called by this function with "return netif_rx(skb);". So this function should follow this behavior, too. 2) In "lapbether", skb_cow is called after skb_push. This results in 2 logical issues: a) skb_push is not protected by skb_cow; b) An extra headroom of 1 byte is ensured after skb_push. This extra headroom has no use in this function. It also has no use in the upper-layer function that this function passes the skb to (x25_lapb_receive_frame in net/x25/x25_dev.c). So logically skb_cow should instead be called before skb_push.

2020-07-24xen-netfront: fix potential deadlock in xennet_remove()Andrea Righi
There's a potential race in xennet_remove(); this is what the driver is doing upon unregistering a network device: 1. state = read bus state 2. if state is not "Closed": 3. request to set state to "Closing" 4. wait for state to be set to "Closing" 5. request to set state to "Closed" 6. wait for state to be set to "Closed" If the state changes to "Closed" immediately after step 1 we are stuck forever in step 4, because the state will never go back from "Closed" to "Closing". Make sure to check also for state == "Closed" in step 4 to prevent the deadlock. Also add a 5 sec timeout any time we wait for the bus state to change, to avoid getting stuck forever in wait_event().

2020-07-24soc: ti: k3-ringacc: add request pair of rings api.Grygorii Strashko
Add new API k3_ringacc_request_rings_pair() to request pair of rings at once, as in the most cases Rings are used with DMA channels, which need to request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and one to receive completions (RX/TX CQ). This will allow to simplify Ringacc API users.

2020-07-24mtd: properly check all write ioctls for permissionsGreg Kroah-Hartman
When doing a "write" ioctl call, properly check that we have permissions to do so before copying anything from userspace or anything else so we can "fail fast". This includes also covering the MEMWRITE ioctl which previously missed checking for this.
