LoongArch: mm/vma: define a default value for VM_DATA_DEFAULT_FLAGS

[PATCH] LoongArch: mm/vma: define a default value for VM_DATA_DEFAULT_FLAGS

Posted by WangYuli 3 weeks, 1 day ago

Commit c62da0c35d58 ("mm/vma: define a default value for
VM_DATA_DEFAULT_FLAGS") has unified default values of
VM_DATA_DEFAULT_FLAGS across different platforms.

Apply the same consistency to LoongArch.
