From: Shameer Kolothum <shameerali.kolothum.thodi@huawei.com> mainline inclusion from mainline-v6.15-rc1 commit c8c2647e69bedf803244eabc80e2e0757f9c33d6 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IBN3WI Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- Subsequent patch will add target implementation CPU support and that will require _midr_in_range_list() to access new data. To avoid exporting the data make _midr_in_range_list() a normal function and export it. No functional changes intended.
