riscv: stacktrace: Disable KASAN checks for non-current tasks
[ Upstream commit 060ea84a484e852b52b938f234bf9b5503a6c910 ]
Unwinding the stack of a task other than current, KASAN would report
"BUG: KASAN: out-of-bounds in walk_stackframe+0x41c/0x460"
There is a same issue on x86 and has been resolved by the commit
84936118bdf3 ("x86/unwind: Disable KASAN checks for non-current tasks")
The solution could be applied to RISC-V too.
This patch also can solve the issue:
