Patches 1-4 are the old page isolation solution (enable_soft_offline + panic prevention), already delivered to customers. Original PR: https://atomgit.com/openeuler/kernel/merge_requests/20004 Patches 5-11 are the new solution, enabling automated configuration in the new version: Patches 5-7 remove the redundant enable_soft_offline bit 1 huge page isolation switch from the old solution, and copy mc only supports THP and regular pages. Patch 8 adds sysctl_apei_page_offline_policy to support regular/huge page isolation policies and driver notification chain. Patch 9-11 fix bugs. Changes in v7: Use blocking notifier for page offline policy chain Changes in v6: Fix panic casued by UCE in kernel context (!current->mm). Changes in v5: Change sysctl_apei_page_offline_policy bit0 to enable/disable driver notification. Backport some patches that have been merged. Since CONFIG_UCE_KERNEL_RECOVERY depends on CONFIG_ARM64, remove the redundant condition in migrate_page(). Changes in v4: Fix typo errors and backport bugfix for mc_copy. Changes in v3: Use bool rather than int as the return type of apei_page_should_offline(). Drop the PF_UCE_KERNEL_RECOVERY flag after soft-offlining the page. Changes in v2: Add a new sysctl_apei_page_offline_policy, instead of changing soft_offline_page.
