2021-10-21nbd: Use invalidate_disk() helper on disconnectXie Yongji
When a nbd device encounters a writeback error, that error will get propagated to the bd_inode's wb_err field. Then if this nbd device's backend is disconnected and another is attached, we will get back the previous writeback error on fsync, which is unexpected. To fix it, let's use invalidate_disk() helper to invalidate the disk on disconnect instead of just setting disk's capacity to zero.

The lo->lo_device can't be null if the lo->lo_backing_file is set. So let's remove the unnecessary bdev checks and the entire bdev variable in __loop_clr_fd() since the lo->lo_backing_file is already checked before.

We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. There are two calls to dm_setup_md_queue() which can fail then, one on dm_early_create() and we can easily see that the error path there calls dm_destroy in the error path. The other use case is on the ioctl table_load case. If that fails userspace needs to call the DM_DEV_REMOVE_CMD to cleanup the state - similar to any other failure.

2021-10-21x86/CPU: Add support for Vortex CPUsMarcos Del Sol Vives
DM&P devices were not being properly identified, which resulted in unneeded Spectre/Meltdown mitigations being applied. The manufacturer states that these devices execute always in-order and don't support either speculative execution or branch prediction, so they are not vulnerable to this class of attack. [1] This is something I've personally tested by a simple timing analysis on my Vortex86MX CPU, and can confirm it is true. Add identification for some devices that lack the CPUID product name call, so they appear properly on /proc/cpuinfo. ¹https://www.ssv-embedded.de/doks/infos/DMP_Ann_180108_Meltdown.pdf [ bp: Massage commit message. ] Signed-off-by: Marcos Del Sol Vives <marcos@orca.pet> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/20211017094408.1512158-1-marcos@orca.pet

Add the configuration for pm6350 regulators. The supplies are not known so leave them out for now. Additionally leave out configuration of smps3 - smps5 and ldo17 as these are not configured in the downstream kernel and the type of them is not known.

2021-10-21regulator: lp872x: Remove lp872x_dvs_stateNathan Chancellor
After this driver was converted to gpiod, clang started warning: vers/regulator/lp872x.c:689:57: error: implicit conversion from enumeration type 'enum lp872x_dvs_state' to different enumeration type 'enum gpiod_flags' [-Werror,-Wenum-conversion] dvs->gpio = devm_gpiod_get_optional(lp->dev, "ti,dvs", pinstate); ~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~ 1 error generated. lp872x_dvs_state was updated to have values from gpiod_flags but this is not enough to avoid an implicit conversion warning from either GCC or clang (although GCC enables this warning under -Wextra instead of -Wall like clang so it is not seen under normal builds). Eliminate lp872x_dvs_state in favor of using gpiod_flags everywhere so that there is no more warning about an implicit conversion.
