stable inclusion from stable-v5.10.122 commit 32be2b805a1a13ccc68bd209ec3ae198dd3ba5d6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE

--------------------------------
[ Upstream commit b24192a17337abbf3f44aaa75e15df14a2d0016e ]
The function percent_rmt_hitm_cmp() wrongly uses local HITMs for sorting remote HITMs.
Since this function is to sort cache lines for remote HITMs, this patch changes to use 'rmt_hitm' field for correct sorting.
