Add support for getting the maximum virtual address, LoongArch has multiple
address space layouts, the default maximum virtual address of the current
user space is 47 bits. (from TASK_SIZE in the kernel for loongarch64).

Yes, of course, I will adjust it. Initially just wanted to be consistent with asan_mapping.h (asan only supports 47 bit in loongarch64 for now). |
