2021-02-15thermal: ti-soc-thermal: Fix stuck sensor with continuous mode for 4430Tony Lindgren
At least for 4430, trying to use the single conversion mode eventually hangs the thermal sensor. This can be quite easily seen with errors: thermal thermal_zone0: failed to read out thermal zone (-5) Also, trying to read the temperature shows a stuck value with: $ while true; do cat /sys/class/thermal/thermal_zone0/temp; done Where the temperature is not rising at all with the busy loop. Additionally, the EOCZ (end of conversion) bit is not rising on 4430 in single conversion mode while it works fine in continuous conversion mode. It is also possible that the hung temperature sensor can affect the thermal shutdown alert too. Let's fix the issue by adding TI_BANDGAP_FEATURE_CONT_MODE_ONLY flag and use it for 4430. Note that we also need to add udelay to for the EOCZ (end of conversion) bit polling as otherwise we have it time out too early on 4430. We'll be changing the loop to use iopoll in the following clean-up patch.

2021-02-15thermal: ti-soc-thermal: Skip pointless register access for dra7Tony Lindgren
On dra7, there is no Start of Conversion (SOC) register bit and we have an empty bgap_soc_mask in the configuration for the thermal driver. Let's not do pointless reads and writes with the empty mask. There's also no point waiting for End of Conversion bit (EOCZ) to go high on dra7. We only care about it going down, and are now mostly timing out waiting for EOCZ high while it has already gone down. When we add checking for the timeout errors in a later patch, waiting for EOCZ high would cause bogus time out errors.

2021-02-15proc: don't allow async path resolution of /proc/thread-self componentsJens Axboe
If this is attempted by an io-wq kthread, then return -EOPNOTSUPP as we don't currently support that. Once we can get task_pid_ptr() doing the right thing, then this can go away again. Use PF_IO_WORKER for this to speciically target the io_uring workers. Modify the /proc/self/ check to use PF_IO_WORKER as well.

2021-02-15binfmt_misc: pass binfmt_misc flags to the interpreterLaurent Vivier
It can be useful to the interpreter to know which flags are in use. For instance, knowing if the preserve-argv[0] is in use would allow to skip the pathname argument. This patch uses an unused auxiliary vector, AT_FLAGS, to add a flag to inform interpreter if the preserve-argv[0] is enabled. Note by Helge Deller: The real-world user of this patch is qemu-user, which needs to know if it has to preserve the argv[0]. See Debian bug #970460.

2021-02-15netfilter: nftables: introduce table ownershipPablo Neira Ayuso
A userspace daemon like firewalld might need to monitor for netlink updates to detect its ruleset removal by the (global) flush ruleset command to ensure ruleset persistency. This adds extra complexity from userspace and, for some little time, the firewall policy is not in place. This patch adds the NFT_TABLE_F_OWNER flag which allows a userspace program to own the table that creates in exclusivity. Tables that are owned... - can only be updated and removed by the owner, non-owners hit EPERM if they try to update it or remove it. - are destroyed when the owner closes the netlink socket or the process is gone (implicit netlink socket closure). - are skipped by the global flush ruleset command. - are listed in the global ruleset. The userspace process that sets on the NFT_TABLE_F_OWNER flag need to leave open the netlink socket. A new NFTA_TABLE_OWNER netlink attribute specifies the netlink port ID to identify the owner from userspace. This patch also updates error reporting when an unknown table flag is specified to change it from EINVAL to EOPNOTSUPP given that EINVAL is usually reserved to report for malformed netlink messages to userspace.

IRQ 27: no longer affine to CPU2 IRQ128: set affinity failed(-22). IRQ130: set affinity failed(-22). IRQ131: set affinity failed(-22). IRQ 28: no longer affine to CPU3 IRQ128: set affinity failed(-22). IRQ130: set affinity failed(-22). IRQ131: set affinity failed(-22). Entering suspend state LP1 Hence just don't specify the irq_set_affinity callback if parent PMC IRQ domain is missing. Tegra isn't capable of setting affinity per GPIO, affinity could be set only per GPIO bank, thus there is nothing to do for gpio-tegra in regards to CPU affinity without the parent IRQ domain.

2021-02-15gpio: tegra: Support building driver as a loadable moduleDmitry Osipenko
Support building driver as a loadable kernel module. This allows to reduce size of a kernel zImage, which is important for some devices since size of kernel partition may be limited and since some bootloader variants have known problems in regards to the initrd placement if kernel image is too big. $ lsmod Module Size Used by gpio_tegra 16384 27 Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
