v1 - > v2:1. When the macro __loongarch_lp64 is defined, the VTV_PAGE_SIZE is set to 64K. 2. In the vtv_malloc.cc file __vtv_malloc_init function, it does not check whether VTV_PAGE_SIZE is equal to the system page size, if the macro __loongarch_lp64 is defined. v2 -> v3: Set VTV_PAGE_SIZE to 16KiB for loongarch64. v3 -> v4: Modifying the description. --------------------------------------- The loongarch64 specification permits page sizes of 4KiB, 16KiB and 64KiB, but only 16KiB pages are supported for now.
