category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8M8F9


CVE: NA

--------------------------------

On Hisilicon LINXICORE9100 cores, sharing tlb entries on two cores when
TTBRx.CNP=1 differs from the standard ARM core. This causes issues when tlb
entries sharing between CPU cores. Avoid these issues by disabling CNP
feature for Hisilicon LINXICORE9100 cores.
