In this patchset, we remove the unused macro EX_TYPE_COPY and centralize the processing of memory-failure to do_machine_check() to avoid calling memory_failure_queue() separately for different MC-Safe scenarios. In addition, MCE_IN_KERNEL_COPYIN is renamed MCE_IN_KERNEL_COPY_MC to expand its usage scope. [1]https://lore.kernel.org/linux-mm/20230526063242.133656-1-wangkefeng.wang@xxxxxxxxxx/ since v4: 1. Patch1, suggested by Petkov, changes as follows: a.Improve the commit msg. b.Directly delete the unused fixup_type EX_TYPE_COPY instead of disrupting the overall layout. 2. Patch2/3, improve the commit msg suggested by Petkov. 3. To better describe the problem, reorder the patch 2/3. since v3: 1. Rebased on linux-next tag next-20240111. 2. Delete duplicate commit references on patch 3. since v2: 1. remove redundant fixup type EX_TYPE_COPY. 2. rename MCE_IN_KERNEL_COPYIN to MCE_IN_KERNEL_COPY_MC. 3. update patch3's commit message and the processing logic of EX_TYPE_DEFAULT_MCE_SAFE based on the discussion of [1].
