In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Set correct protection_map[] for VM_NONE/VM_SHARED
For 32BIT platform _PAGE_PROTNONE is 0, so set a VMA to be VM_NONE or VM_SHARED will make pages non-present, then cause Oops with kernel page fault.
Fix it by set correct protection_map[] for VM_NONE/VM_SHARED, replacing _PAGE_PROTNONE with _PAGE_PRESENT.
