Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote). Upstream: https://github.com/xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2)

|
* arc_unwind_core - Unwind the kernel mode stack for an execution context
|
|
* @tsk: NULL for current task, specific task otherwise
|
|
* @regs: pt_regs used to seed the unwinder {SP, FP, BLINK, PC}
|
|
* If NULL, use pt_regs of @tsk (if !NULL) otherwise
|
|
* use the current values of {SP, FP, BLINK, PC}
|
|
* @consumer_fn: Callback invoked for each frame unwound
|
|
* Returns 0 to continue unwinding, -1 to stop
|
|
* @arg: Arg to callback
|
|
*
|
|
* Returns the address of first function in stack
|
|
*
|
|
* Semantics:
|
|
* - synchronous unwinding (e.g. dump_stack): @tsk NULL, @regs NULL
|
|
* - Asynchronous unwinding of sleeping task: @tsk !NULL, @regs NULL
|
|
* - Asynchronous unwinding of intr/excp etc: @tsk !NULL, @regs !NULL
