+Subject: [PATCH] Add support for loongarch64 architecture in ld.hugetlbfs
+
+- Added alignment configuration for loongarch64 architecture in the `ld.hugetlbfs` script.
+- Set `HPAGE_SIZE` to 32MB and `SLICE_SIZE` to match `HPAGE_SIZE` for loongarch64.
+- This ensures correct alignment and hugepage usage for binaries targeting loongarch64 systems.
+
+Fix: https://github.com/libhugetlbfs/libhugetlbfs/issues/91
+Referenc: https://github.com/llvm/llvm-project/blob/main/lld/ELF/Driver.cpp#L217

-Subject: [PATCH] elflink.c: remap segments with MAP_SHARED flag
-
-Mmapping segment with MAP_PRIVATE will create a private
-copy-on-write mapping, as a result updates to the mapping
-will cost extra pages. It will cost double number of pages
-in the worst case, so we change to MAP_SHARED flag.
-
-It is also safe to mmap a unlinked file or a read-only file.
