By default, the number of the address bits used in address translation
is the number of address bits. But it can be changed by ARM Top-byte
Ignore (TBI) or Intel Linear Address Masking (LAM).
<sys/tagged-address.h> provides an API for tagged address manipulation:
/* Get the current address bits used in address translation. */
extern unsigned int get_tagged_address_bits (void);
/* Get the current mask for address bits used in address translation. */
extern uintptr_t get_tagged_address_mask (void);
/* Set the mask for address bits used in address translation. Return 0
on success. Return -1 on error. */
extern int set_tagged_address_mask (uintptr_t __mask);
/* Return the tagged address of __ADDR with the tag value __TAG. */
extern void *tag_address (void *__addr, unsigned int __tag);
/* Return the untagged address of __ADDR. */
extern void *untag_address (void *__addr);
/* TRUE if constant address BITS is a valid tagged address bits. */
#define TAGGED_ADDRESS_VALID_BITS(BITS)
/* A mask for constant address BITS used in address translation. */
#define TAGGED_ADDRESS_MASK(BITS)
1. set_tagged_address_mask should be called as early as possible.
2. set_tagged_address_mask shouldn't be allowed after main is called.
3. After set_tagged_address_mask is called, don't allow it to be called
again to change the tagged address mask. Otherwise, the previously
tagged addresses may not work anymore.

+@Theglibc{} provides several functions and macros in the header file

+the number of the address bits used in address translation.

+@deftypefun {unsigned int} get_tagged_address_bits (void)

+Set the mask for address bits used in address translation to @var{mask}.
+The return value is @code{0} on success and @code{-1} on failure. This
