[ Upstream commit da6c2add ] To set the mux mode of a pin two bits must be set. Up to now this is implemented using the following idiom: writel(mask, reg + CLR); writel(value, reg + SET); . This however results in the mux mode being 0 between the two writes. On my machine there is an IC's reset pin connected to LCD_D20. The bootloader configures this pin as GPIO output-high (i.e. not holding the IC in reset). When Linux reconfigures the pin to GPIO the short time LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse the connected IC. The same problem is present for the pin's drive strength setting which is reset to low drive strength before using the right value. So instead of relying on the hardware to modify the register setting using two writes implement the bit toggling using read-modify-write.

[ Upstream commit 97ba26b8 ] The nand_groups table uses different names for the NAND DQS pins than the GROUP() definition in meson8b_cbus_groups (nand_dqs_0 vs nand_dqs0). This prevents using the NAND DQS pins in the devicetree. Fix this by ensuring that the GROUP() definition and the meson8b_cbus_groups use the same name for these pins.

[ Upstream commit 6836796d ] The USB core and sysfs will attempt to enumerate certain parameters which are unsupported by the au0828 - causing inconsistent behavior and sometimes causing the chip to reset. Avoid making these calls. This problem manifested as intermittent cases where the au8522 would be reset on analog video startup, in particular when starting up ALSA audio streaming in parallel - the sysfs entries created by snd-usb-audio on streaming startup would result in unsupported control messages being sent during tuning which would put the chip into an unknown state.

It can't be reproduced easily. Commit 0b6ac343 (KVM: nVMX: Correct handling of exception injection) mentioned that "KVM wants to inject page-faults which it got to the guest. This function assumes it is called with the exit reason in vmcs02 being a #PF exception". Commit e011c663 (KVM: nVMX: Check all exceptions for intercept during delivery to L2) allows to check all exceptions for intercept during delivery to L2. However, there is no guarantee the exit reason is exception currently, when there is an external interrupt occurred on host, maybe a time interrupt for host which should not be injected to guest, and somewhere queues an exception, then the function nested_vmx_check_exception() will be called and the vmexit emulation codes will try to emulate the "Acknowledge interrupt on exit" behavior, the warning is triggered. Reusing the exit reason from the L2->L0 vmexit is wrong in this case, the reason must always be EXCEPTION_NMI when injecting an exception into L1 as a nested vmexit.

[ Upstream commit f7116e11 ] dma_pte_free_level() recurses down the IOMMU page tables and frees directory pages that are entirely contained in the given PFN range. Unfortunately, it incorrectly calculates the starting address covered by the PTE under consideration, which can lead to it clearing an entry that is still in use. This occurs if we have a scatterlist with an entry that has a length greater than 1026 MB and is aligned to 2 MB for both the IOMMU and physical addresses. For example, if __domain_mapping() is asked to map a two-entry scatterlist with 2 MB and 1028 MB segments to PFN 0xffff80000, it will ask if dma_pte_free_pagetable() is asked to PFNs from 0xffff80200 to 0xffffc05ff, it will also incorrectly clear the PFNs from 0xffff80000 to 0xffff801ff because of this issue. The current code will set level_pfn to 0xffff80200, and 0xffff80200-0xffffc01ff fits inside the range being cleared. Properly setting the level_pfn for the current level under consideration catches that this PTE is outside of the range being cleared. This patch also changes the value passed into dma_pte_free_level() when it recurses. This only affects the first PTE of the range being cleared, and is handled by the existing code that ensures we start our cursor no lower than start_pfn. This was found when using dma_map_sg() to map large chunks of contiguous memory, which immediatedly led to faults on the first access of the erroneously-deleted mappings.

[ Upstream commit 9e25ebfe ] The pmd containing memblock_limit is cleared by prepare_page_table() which creates the opportunity for early_alloc() to allocate unmapped memory if memblock_limit is not pmd aligned causing a boot-time hang. Commit 965278dc ("ARM: 8356/1: mm: handle non-pmd-aligned end of RAM") attempted to resolve this problem, but there is a path through the adjust_lowmem_bounds() routine where if all memory regions start and end on pmd-aligned addresses the memblock_limit will be set to arm_lowmem_limit. Since arm_lowmem_limit can be affected by the vmalloc early parameter, the value of arm_lowmem_limit may not be pmd-aligned. This commit corrects this oversight such that memblock_limit is always rounded down to pmd-alignment. Fixes: 965278dc ("ARM: 8356/1: mm: handle non-pmd-aligned end of RAM") Signed-off-by:

[ Upstream commit 9b3eb541 ] When CONFIG_XFRM_SUB_POLICY=y, xfrm_dst stores a copy of the flowi for that dst. Unfortunately, the code that allocates and fills this copy doesn't care about what type of flowi (flowi, flowi4, flowi6) gets passed. In multiple code paths (from raw_sendmsg, from TCP when replying to a FIN, in vxlan, geneve, and gre), the flowi that gets passed to xfrm is actually an on-stack flowi4, so we end up reading stuff from the stack past the end of the flowi4 struct. Since xfrm_dst->origin isn't used anywhere following commit ca116922 ("xfrm: Eliminate "fl" and "pol" args to xfrm_bundle_ok()."), just get rid of it. xfrm_dst->partner isn't used either, so get rid of that too.

[ Upstream commit 7292ae3d ] The latest change of asm goto support check added passing of KBUILD_CFLAGS to compiler. When these flags reference gcc plugins that are not built yet, the check fails. When one runs "make bzImage" followed by "make modules", the kernel is always built with HAVE_JUMP_LABEL disabled, while the modules are built depending on CONFIG_JUMP_LABEL. If HAVE_JUMP_LABEL macro happens to be different, modules are built with undefined references, e.g.: ERROR: "static_key_slow_inc" [net/netfilter/xt_TEE.ko] undefined! ERROR: "static_key_slow_dec" [net/netfilter/xt_TEE.ko] undefined! ERROR: "static_key_slow_dec" [net/netfilter/nft_meta.ko] undefined!

ERROR: "static_key_count" [net/ipv6/ipv6.ko] undefined! ERROR: "static_key_slow_inc" [net/ipv6/ipv6.ko] undefined! This change moves the check before all these references are added to KBUILD_CFLAGS. This is correct because subsequent KBUILD_CFLAGS modifications are not relevant to this check. Reported-by:

[ Upstream commit e991c24d ] We have quite a lot of code that depends on the order of the __ctl_load inline assemby and subsequent memory accesses, like e.g. disabling lowcore protection and the writing to lowcore. Since the __ctl_load macro does not have memory barrier semantics, nor any other dependencies the compiler is, theoretically, free to shuffle code around. Or in other words: storing to lowcore could happen before lowcore protection is disabled. In order to avoid this class of potential bugs simply add a full memory barrier to the __ctl_load macro.

[ Upstream commit a89af4ab ] Support for the Asus Touchpad was recently added. It turns out this device can fail initialisation (and become unusable) when the RESET command is sent too soon after the POWER ON command. Unfortunately the i2c-hid specification does not specify the need for a delay between these two commands. But it was discovered the Windows driver has a 1ms delay. As a result, this patch modifies the i2c-hid module to add a sleep inbetween the POWER ON and RESET commands which lasts between 1ms and 5ms.
