[ Upstream commit d9101bfa ] __find_linux_mm_pte() returns a page table entry pointer after walking the page table without holding locks. To make it safe against a THP split and/or collapse, we disable interrupts around the lockless page table walk. However we need to keep interrupts disabled as long as we use the page table entry pointer that is returned. Fix addr_to_pfn() to do that.

[ Upstream commit ed309bfb ] Since the helper "owl_factor_helper_round_rate" is shared between factor and composite clocks, using the factor clk specific helper function like "hw_to_owl_factor" to access its members will create issues when called from composite clk specific code. Hence, pass the "factor_hw" struct pointer directly instead of fetching it using factor clk specific helpers. This issue has been observed when a composite clock like "sd0_clk" tried to call "owl_factor_helper_round_rate" resulting in pointer dereferencing error. While we are at it, let's rename the "clk_val_best" function to "owl_clk_val_best" since this is an owl SoCs specific helper. Fixes: 4bb78fc9 ("clk: actions: Add factor clock support") Signed-off-by:

[ Upstream commit b7139960 ] When the FW bundles multiple packets, pkt->act_len may be incorrect as it refers to the first packet only (however, the FW will only bundle packets that fit into the same pkt->alloc_len). Before this patch, the skb length would be set (incorrectly) to pkt->act_len in ath10k_sdio_mbox_rx_packet, and then later manually adjusted in ath10k_sdio_mbox_rx_process_packet. The first problem is that ath10k_sdio_mbox_rx_process_packet does not use proper skb_put commands to adjust the length (it directly changes skb->len), so we end up with a mismatch between skb->head + skb->tail and skb->data + skb->len. This is quite serious, and causes corruptions in the TCP stack, as the stack tries to coalesce packets, and relies on skb->tail being correct (that is, skb_tail_pointer must point to the first byte_after_ the data). Instead of re-adjusting the size in ath10k_sdio_mbox_rx_process_packet, this moves the code to ath10k_sdio_mbox_rx_packet, and also add a bounds check, as skb_put would crash the kernel if not enough space is available. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1. Fixes: 8530b4e7 ("ath10k: sdio: set skb len for all rx packets") Signed-off-by:

[ Upstream commit e7ba676c ] In Xen environment, if Xen-swiotlb is enabled, ixgbe driver could possibly allocate a page, DMA memory buffer, for the first fragment which is not suitable for Xen-swiotlb to do DMA operations. Xen-swiotlb have to internally allocate another page for doing DMA operations. This mechanism requires syncing the data from the internal page to the page which ixgbe sends to upper network stack. However, since commit f3213d93 ("ixgbe: Update driver to make use of DMA attributes in Rx path"), the unmap operation is performed with DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed. Since the sync isn't performed, the upper network stack could receive a incomplete network packet. By incomplete, it means the linear data on the first fragment(between skb->head and skb->end) is invalid. So we have to copy the data from the internal xen-swiotlb page to the page which ixgbe sends to upper network stack through the sync operation. More details from Alexander Duyck: Specifically since we are mapping the frame with DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result a sync is not performed on an unmap and must be done manually as we skipped it for the first frag. As such we need to always sync before possibly performing a page unmap operation.

[ Upstream commit c09767a8 ] generic_write_checks() may modify iov_iter_count(), so we must get the count after the call, not before. Using the wrong one has a couple of consequences: 1. We check a longer range in check_can_nocow() for nowait than we're actually writing. 2. We create extra hole extent maps in btrfs_cont_expand(). As far as I can tell, this is harmless, but I might be missing something. These issues are pretty minor, but let's fix it before something more important trips on it.

[ Upstream commit 7764d56b ] If we are able to load an existing inode cache off disk, we set the state of the cache to BTRFS_CACHE_FINISHED, but we don't wake up any one waiting for the cache to be available.

[ Upstream commit a932b77b ] When the pinmux configuration was added, it was accidentally placed into the omap3_pmx_wkup node when it should have been placed into the omap3_pmx_core. This error was accidentally propagated to stable by me when I blindly requested the pull after seeing I2C issues without actually reviewing the content of the pinout. Since the bootloader previously muxed these correctly in the past, was a hidden error. This patch moves the i2c2_pins and i2c3_pins to the correct node which should eliminate i2c bus errors and timeouts due to the fact the bootloader uses the save device tree that no longer properly assigns these pins.

[ Upstream commit 355cf319 ] clang triggers a warning about oversized stack frames that gcc does not notice because of slightly different inlining decisions: ath/wcn36xx/smd.c:1409:5: error: stack frame size of 1040 bytes in function 'wcn36xx_smd_config_bss' [-Werror,-Wframe-larger-than=] ath/wcn36xx/smd.c:640:5: error: stack frame size of 1032 bytes in function 'wcn36xx_smd_start_hw_scan' [-Werror,-Wframe-larger-than=] Basically the wcn36xx_hal_start_scan_offload_req_msg, wcn36xx_hal_config_bss_req_msg_v1, and wcn36xx_hal_config_bss_req_msg structures are too large to be put on the kernel stack, but small enough that gcc does not warn about them. Use kzalloc() to allocate them all. There are similar structures in other parts of this driver, but they are all smaller, with the next largest stack frame at 480 bytes for wcn36xx_smd_send_beacon.
