[PATCH v13 2/5] arm64: add support for ARCH_HAS_COPY_MC

2024-12-08 Thread Tong Tiangen
For the arm64 kernel, when it processes hardware memory errors for synchronize notifications(do_sea()), if the errors is consumed within the kernel, the current processing is panic. However, it is not optimal. Take copy_from/to_user for example, If ld* triggers a memory error, even in kernel mode,
