euleros inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7RO5Q Reference: https://gitee.com/openeuler/kernel/commit/74706f34e144e1bf95914d2e36eb29d40f...
-------------------------------------------------
fix compile error when CONFIG_NUMA is turned off on Raspberry platform.
compile info: mm/vmscan.c: In function ‘get_page_from_vaddr’: mm/vmscan.c:4350:40: error: implicit declaration of function ‘vma_migratable’; did you mean ‘rq_mergeable’? [-Werror=implicit-function-declaration]
This patch solves the problem of compilation errors introduced by memig into the interface in the vmscan.c file. Delete dependency on NUMA for CONFIG_MEMIG_SWAP, and use vma->vm_flags & VM_LOCKED for judgement.
