[ Upstream commit 5778b13b ] After resetting dsaf to try to repair chip error such as ecc error, the net device will be open if net interface is up. But at this time if there is the users set the net device up with the command ifconfig, the net device will be opened twice consecutively. Function napi_enable was called when open device. And Kernel panic will be occurred if it was called twice consecutively. Such as follow: static inline void napi_enable(struct napi_struct *n) { BUG_ON(!test_bit(NAPI_STATE_SCHED, &n->state)); smp_mb__before_clear_bit(); clear_bit(NAPI_STATE_SCHED, &n->state); } [37255.571996] Kernel panic - not syncing: BUG!

[ Upstream commit 308c6caf ] There are two test cases: 1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio, and install them again, must use "ifconfig down/ifconfig up" command pair to bring port to work. This patch calls phy_stop function when init phy to fix this bug. 2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again, all ports can not use anymore, because of the phy devices register failed(phy devices already exists). Phy devices are registered when hns_dsaf installed, this patch removes them when hns_dsaf removed. The two cases are sometimes related, fixing the second case also requires fixing the first case, so fix them together. Signed-off-by:

[ Upstream commit 04f05230 ] Vlans are not getting removed when drivers are unloaded. The recent storm firmware versions had added safeguards against re-configuring an already configured vlan. As a result, PF inner reload flows (e.g., mtu change) might trigger an assertion. This change is going to remove vlans (same as we do for MACs) when doing a chip cleanup during unload. Signed-off-by:

[ Upstream commit 158daed1 ] A previous commit moved the ether_addr_copy() in i40e_set_mac() before the mac filter del/add to avoid a race. However it wasn't taken into account that this alters the mac address being handed to i40e_del_mac_filter(). Also changed i40e_add_mac_filter() to operate on netdev->dev_addr, hopefully that makes the code easier to read.

[ Upstream commit 16877a55 ] There is a guard hole at the beginning of the kernel address space, also used by hypervisors. It occupies 16 PGD entries. This reserved range is not defined explicitely, it is calculated relative to other entities: direct mapping and user space ranges. The calculation got broken by recent changes of the kernel memory layout: LDT remap range is now mapped before direct mapping and makes the calculation invalid. The breakage leads to crash on Xen dom0 boot[1]. Define the reserved range explicitely. It's part of kernel ABI (hypervisors expect it to be stable) and must not depend on changes in the rest of kernel memory layout.

[ Upstream commit e2ca26ec ] With PM enabled, I noticed that pressing a key on the droid4 keyboard will block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as suggested by Dmitry Torokhov <dmitry.torokhov@gmail.com>. From the hardware point of view, looks like we need to manage the registers for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE register now gone with IRQF_ONESHOT, also the SoC idle state problem is gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent blocking deeper SoC idle states after rmmod omap4-keypad. Reported-by:

[ Upstream commit 0152eee6 ] Since commit 222d7dbd ("net: prevent dst uses after free") skb_dst_force() might clear the dst_entry attached to the skb. The xfrm code doesn't expect this to happen, so we crash with a NULL pointer dereference in this case. Fix it by checking skb_dst(skb) for NULL after skb_dst_force() and drop the packet in case the dst_entry was cleared. We also move the skb_dst_force() to a codepath that is not used when the transformation was offloaded, because in this case we don't have a dst_entry attached to the skb. The output and forwarding path was already fixed by commit 9e143793 ("xfrm: Fix NULL pointer dereference when skb_dst_force clears the dst_entry.")

Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

[ Upstream commit 40502074 ] The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is likely another ITE based design. The controller die is directly bonded to the PCB with a blob of black glue on top so there are no markings and the 258a vendor-id used is unknown anywhere. But the keyboard has the exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard I have *and* it has the same quirky behavior wrt the rfkill hotkey. Either way as said this keyboard has the same quirk for its rfkill / airplane mode hotkey as the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard. Signed-off-by:

[ Upstream commit 5564597d ] Commit 6975a783 ("powerpc/boot: Allow building the zImage wrapper as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor at the start of crt0.S to have a hard-coded start address of 0x500000 rather than a reference to _zimage_start, presumably because having a reference to a symbol introduced a relocation which is awkward to handle in a position-independent executable. Unfortunately, what is at 0x500000 in the COFF image is not the first instruction, but the procedure descriptor itself, that is, a word containing 0x500000, which is not a valid instruction. Hence, booting a COFF zImage results in a "DEFAULT CATCH!, code=FFF00700" message from Open Firmware. This fixes the problem by (a) putting the procedure descriptor in the data section and (b) adding a branch to _zimage_start as the first instruction in the program.

[ Upstream commit 614b1868 ] We just changed the code so we apply bias disable on the correct register but forgot to align the register calculation. The result is that we apply the change on the correct register, but possibly at the incorrect offset/bit This went undetected because offsets tends to be the same between REG_PULL and REG_PULLEN for a given pin the EE controller. This is not true for the AO controller. Fixes: e39f9dd8 ("pinctrl: meson: fix pinconf bias disable") Signed-off-by:

commit 66a4059b upstream. MIPS' asm/mmzone.h includes the machine/platform mmzone.h unconditionally, but since commit bb53fdf3 ("MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3") is included by asm/rk4cache.h for all r4k-style configs regardless of CONFIG_NEED_MULTIPLE_NODES. This is problematic when CONFIG_NEED_MULTIPLE_NODES=n because both the loongson3 & ip27 mmzone.h headers unconditionally define the NODE_DATA preprocessor macro which is aready defined by linux/mmzone.h, resulting in the following build error: In file included from ./arch/mips/include/asm/mmzone.h:10, from ./arch/mips/include/asm/r4kcache.h:23, from arch/mips/mm/c-r4k.c:33: ./arch/mips/include/asm/mach-loongson64/mmzone.h:48: error: "NODE_DATA" redefined [-Werror] #define NODE_DATA(n) (&__node_data[(n)]->pglist) In file included from ./include/linux/topology.h:32, from ./include/linux/irq.h:19, from ./include/asm-generic/hardirq.h:13, from ./arch/mips/include/asm/hardirq.h:16, from ./include/linux/hardirq.h:9, from arch/mips/mm/c-r4k.c:11: ./include/linux/mmzone.h:907: note: this is the location of the previous definition #define NODE_DATA(nid) (&contig_page_data) Resolve this by only including the machine mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y, which also removes the need for the empty mach-generic version of the header which we delete.

commit 29bdedfd upstream. Commit e82b0b38 ("spi: bcm2835: Fix race on DMA termination") broke the build with COMPILE_TEST=y on arches whose cmpxchg() requires 32-bit operands (xtensa, older arm ISAs). Fix by changing the dma_pending flag's type from bool to unsigned int. Fixes: e82b0b38 ("spi: bcm2835: Fix race on DMA termination") Signed-off-by:

commit 01f54664 upstream. First, rename out_no_locality to out_locality for bailing out on both tpm_cmd_ready() and tpm_request_locality() failure. Second, ignore the return value of go_to_idle() as it may override the return value of the actual tpm operation, the go_to_idle() error will be caught on any consequent command. Last, fix the wrong 'goto out', that jumped back instead of forward. Cc: stable@vger.kernel.org Fixes: 627448e8 ("tpm: separate cmd_ready/go_idle from runtime_pm") Signed-off-by:

commit 3cc9ffbb upstream. Add the missing adjustment of the month range on alarm reads from the RTC, correcting an issue coming from commit 9c6dfed9 ("rtc: m41t80: add alarm functionality"). The range is 1-12 for hardware and 0-11 for `struct rtc_time', and is already correctly handled on alarm writes to the RTC. It was correct up until commit 48e97667 ("drivers/rtc/rtc-m41t80.c: remove disabled alarm functionality") too, which removed the previous implementation of alarm support. Signed-off-by:
