commit cdf8b463 upstream. AT_VECTOR_SIZE_ARCH should be defined with the maximum number of NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined for tile at all even though ARCH_DLINFO will contain one NEW_AUX_ENT for the VDSO address. This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for AT_BASE_PLATFORM which tile doesn't use, but lets define it now and add the comment above ARCH_DLINFO as found in several other architectures to remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to date.

commit 52d210d9 upstream. In ee1d2674 ("pstore: add pstore unregister") I added: .owner = THIS_MODULE, in both pstore_fs_type and pstore_file_operations to increase a reference count when pstore filesystem is mounted and pstore file is opened. But, it's repetitive. There is no need to increase the opened reference count. We only need to increase the mounted reference count. When a file is opened, the filesystem can't be unmounted. Hence the pstore module can't be unloaded either. So I drop the opened reference count in this patch. Fixes: ee1d2674 ("pstore: add pstore unregister") Signed-off-by:

commit 52b9c330 upstream. If ->queue_rq() returns BLK_MQ_RQ_QUEUE_OK, we use continue and skip over the rest of the loop body. However, dptr is assigned later in the loop body, and the BLK_MQ_RQ_QUEUE_OK case is exactly the case that we'd want it for. NVMe isn't actually using BLK_MQ_F_DEFER_ISSUE yet, nor is any other in-tree driver, but if the code's going to be there, it might as well work.

commit 06dfe5cc upstream. SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for the PCMCIA socket class. PCMCIA used to handle suspend/resume via the socket hosting device, which happened at normal device suspend/resume time. However, the referenced commit changed this: much of the resume now happens much earlier, in the noirq resume handler of dev_pm_ops. However, on SA1111, the PCMCIA device is not accessible as the SA1111 has not been resumed at _noirq time. It's slightly worse than that, because the SA1111 has already been put to sleep at _noirq time, so suspend doesn't work properly. Fix this by converting the core SA1111 code to use dev_pm_ops as well, and performing its own suspend/resume at noirq time. This fixes these errors in the kernel log: pcmcia_socket pcmcia_socket0: time out after reset pcmcia_socket pcmcia_socket1: time out after reset and the resulting lack of PCMCIA cards after a S2RAM cycle.

commit c2f32112 upstream. The current implementation only works if the da9xxx devices are added before their drivers are registered. Only then it can apply the fixes to both devices. Otherwise, the driver for the first device gets probed before the fix for the second device can be applied. This is what fails when using the IP core switcher or when having the i2c master driver as a module. So, we need to disable both da9xxx once we detected one of them. We now use i2c_transfer with hardcoded i2c_messages and device addresses, so we don't need the da9xxx client devices to be instantiated. Because the fixup is used on specific boards only, the addresses are not going to change. Fixes: 663fbb52 ("ARM: shmobile: R-Car Gen2: Add da9063/da9210 regulator quirk") Signed-off-by:

commit 29028477 upstream. The voltage ranges listed here are wrong. The correct ranges can be seen in the "native" spmi regulator driver qcom_spmi-regulator.c at pldo_ranges[], ftsmps_ranges[] and boost_ranges[] for the pldo, ftsmps, and boost type regulators. Port these ranges over to the RPM SMD regulator driver so that we list the appropriate set of supported voltages on pldos. Doing this allows us to specify a voltage like 3075000 for l24, whereas before that wasn't a supported voltage. Fixes: da65e367 ("regulator: Regulator driver for the Qualcomm RPM") Signed-off-by:

commit 93bfe79b upstream. The mvs1 and mvs2 switches are actually called 5vs1 and 5vs2 on some datasheets. Let's rename them to match the datasheets and also match the RPM based regulator driver which calls these by their 5vs names (see qcom_smd-regulator.c). There aren't any users of these regulators so far, so there aren't any concerns of DT ABI breakage here. While we're here making updates to the switches, also mandate usage of the OCP irq for these switches too.

commit 305723ab upstream. Malta boards used with CPU emulators feature a switch to disable use of an IOCU. Software has to check this switch & ignore any present IOCU if the switch is closed. The read used to do this was unsafe for 64 bit kernels, as it simply casted the address 0xbf403000 to a pointer & dereferenced it. Whilst in a 32 bit kernel this would access kseg1, in a 64 bit kernel this attempts to access xuseg & results in an address error exception. Fix by accessing a correctly formed ckseg1 address generated using the CKSEG1ADDR macro. Whilst modifying this code, define the name of the register and the bit we care about within it, which indicates whether PCI DMA is routed to the IOCU or straight to DRAM. The code previously checked that bit 0 was also set, but the least significant 7 bits of the CONFIG_GEN0 register contain the value of the MReqInfo signal provided to the IOCU OCP bus, so singling out bit 0 makes little sense & that part of the check is dropped.

MIPS variant used arch_uprobe->orig_inst which was never initialised properly, so this code only inserted a nop instead of the original instruction.

commit 3a402a70 upstream. When TIF_SINGLESTEP is set for a task, the single-step state machine is enabled and we must take care not to reset it to the active-not-pending state if it is already in the active-pending state. Unfortunately, that's exactly what user_enable_single_step does, by unconditionally setting the SS bit in the SPSR for the current task. This causes failures in the GDB testsuite, where GDB ends up missing expected step traps if the instruction being stepped generates another trap, e.g. PTRACE_EVENT_FORK from an SVC instruction. This patch fixes the problem by preserving the current state of the stepping state machine when TIF_SINGLESTEP is set on the current thread. Cc: <stable@vger.kernel.org> Reported-by:

commit 727653d6 upstream. gic_raise_softirq() walks the list of cpus using for_each_cpu(), it calls gic_compute_target_list() which advances the iterator by the number of CPUs in the cluster. If gic_compute_target_list() reaches the last CPU it leaves the iterator pointing at the last CPU. This means the next time round the for_each_cpu() loop cpumask_next() will be called with an invalid CPU.

commit 56beac95 upstream. ucb1x00 has used IRQ probing since it's dawn to find the GPIO interrupt that it's connected to. However, commit 23393d49 ("gpio: kill off set_irq_flags usage") broke this by disabling IRQ probing on GPIO interrupts. Fix this. Fixes: 23393d49 ("gpio: kill off set_irq_flags usage") Signed-off-by:

commit d5d0689a upstream. This fixes a pretty ancient bug that hasn't manifested itself until now. The scratchbuf for command queue is allocated only for 32 slots but is accessed with the queue write pointer - which can be up to 256. Since the scratch buf size was 16 and there are up to 256 TFDs we never passed a page boundary when accessing the scratch buffer, but when attempting to increase the size of the scratch buffer a panic was quick to follow when trying to access the address resulted in a page boundary.

commit c3ccf357 upstream. The conversion from a look-up table to a calculation for clock generator parameters forgot to take into account that BRDV x 1/1 is valid only if BRPS is x 1/1 or x 1/2, leading to undefined behavior (e.g. arbitrary clock rates). This limitation is documented for the MSIOF module in all supported SH/R-Mobile and R-Car Gen2/Gen3 ARM SoCs. Tested on r8a7791/koelsch and r8a7795/salvator-x.

commit a6c50912 upstream. nvmem_cell_read() is declared as void * if CONFIG_NVMEM is enabled, and as char * otherwise. This can result in a build warning if CONFIG_NVMEM is not enabled and a caller asigns the result to a type other than char * without using a typecast. Use a consistent declaration to avoid the problem. Fixes: e2a5402e ("nvmem: Add nvmem_device based consumer apis.") Cc: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by:

commit 3777ed68 upstream. When using HEAD from https://git.kernel.org/cgit/utils/kernel/ipvsadm/ipvsadm.git/, the command: ipvsadm --start-daemon backup --mcast-interface eth0.60 \ --mcast-group ff02::1:81 fails with the error message: Argument list too long whereas both: ipvsadm --start-daemon master --mcast-interface eth0.60 \ --mcast-group ff02::1:81 and: ipvsadm --start-daemon backup --mcast-interface eth0.60 \ --mcast-group 224.0.0.81 are successful. The error message "Argument list too long" isn't helpful. The error occurs because an IPv6 address is given in backup mode. The error is in make_receive_sock() in net/netfilter/ipvs/ip_vs_sync.c, since it fails to set the interface on the address or the socket before calling inet6_bind() (via sock->ops->bind), where the test 'if (!sk->sk_bound_dev_if)' failed. Setting sock->sk->sk_bound_dev_if on the socket before calling inet6_bind() resolves the issue. Fixes: d3328817 ("ipvs: add more mcast parameters for the sync daemon") Signed-off-by:
