## Description

In the Linux kernel, the following vulnerability has been resolved:  LoongArch: Enable exception fixup for specific ADE subcode  This patch allows the LoongArch BPF JIT to handle recoverable memory access errors generated by BPF_PROBE_MEM* instructions.  When a BPF program performs memory access operations, the instructions it executes may trigger ADEM exceptions. The kernel’s built-in BPF exception table mechanism (EX_TYPE_BPF) will generate corresponding exception fixup entries in the JIT compilation phase; however, the architecture-specific trap handling function needs to proactively call the common fixup routine to achieve exception recovery.  do_ade(): fix EX_TYPE_BPF memory access exceptions for BPF programs, ensure safe execution.  Relevant test cases: illegal address access tests in module_attach and subprogs_extable of selftests/bpf.
