Define the device isolation strategy by the device driver. The user configures a hardware error threshold value by uacce interface. If the number of hardware errors exceeds the value of setting error threshold in one hour. The device will not be available in user space. The VF device use the PF device isolation strategy.

2023-01-20uacce: supports device isolation featureKai Ye
UACCE adds the hardware error isolation feature. To improve service reliability, some uacce devices that frequently encounter hardware errors are isolated. Therefore, this feature is added. Users can configure the hardware error threshold by 'isolate_strategy' sysfs node. The user space can get the device isolated state by 'isolate' sysfs node. If the number of device errors exceeds the configured error threshold, the device will be isolated. It means the uacce device is unavailable.

2023-01-20net: dcb: add new rewrite tableDaniel Machon
Add new rewrite table and all the required functions, offload hooks and bookkeeping for maintaining it. The rewrite table reuses the app struct, and the entire set of app selectors. As such, some bookeeping code can be shared between the rewrite- and the APP table. New functions for getting, setting and deleting entries has been added. Apart from operating on the rewrite list, these functions do not emit a DCB_APP_EVENT when the list os modified. The new dcb_getrewr does a lookup based on selector and priority and returns the protocol, so that mappings from priority to protocol, for a given selector and ifindex is obtained. Also, a new nested attribute has been added, that encapsulates one or more app structs. This attribute is used to distinguish the two tables. The dcb_lock used for the APP table is reused for the rewrite table. Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Petr Machata <petrm@nvidia.com> Signed-off-by: David S.

2023-01-19livepatch: Improve the search performance of module_kallsyms_on_each_symbol()Zhen Lei
Currently we traverse all symbols of all modules to find the specified function for the specified module. But in reality, we just need to find the given module and then traverse all the symbols in it. Let's add a new parameter 'const char *modname' to function module_kallsyms_on_each_symbol(), then we can compare the module names directly in this function and call hook 'fn' after matching. If 'modname' is NULL, the symbols of all modules are still traversed for compatibility with other usage cases. Phase1: mod1-->mod2..(subsequent modules do not need to be compared) | Phase2: -->f1-->f2-->f3 Assuming that there are m modules, each module has n symbols on average, then the time complexity is reduced from O(m * n) to O(m) + O(n).

Instead of using the common 'GPA_INVALID' for X86, replace it with 'INVALID_GPA', and change the users of 'GPA_INVALID' so that the diff can be smaller.

This patch provides a generic GPIO variable for outputting the state of RS485 RX_DURING_TX. The GPIO is defined by the devicetree property "rs485-rx-during-tx-gpios". To use it in a low level serial driver, the evaluation of this variable must be implemented there accordingly.

2023-01-19tty: vt: remove struct uni_screenJiri Slaby (SUSE)
It contains only lines with pointers to characters (u32s). So use simple clear 'u32 **lines' all over the code. This avoids zero-length arrays. It also makes the allocation less error-prone (size of the struct wasn't taken into account at all).

2023-01-19bitfield: add FIELD_PREP_CONST()Johannes Berg
Neither FIELD_PREP() nor *_encode_bits() can be used in constant contexts (such as initializers), but we don't want to define shift constants for all masks just for use in initializers, and having checks that the values fit is also useful. Therefore, add FIELD_PREP_CONST() which is a smaller version of FIELD_PREP() that can only take constant arguments and has less friendly (but not less strict) error checks, and expands to a constant value.
