+/* The M7 processor supports an Application Data Integrity (ADI) feature
+ that detects invalid data accesses. When software allocates memory and
+ enables ADI on the allocated memory, it chooses a 4-bit version number,
+ sets the version in the upper 4 bits of the 64-bit pointer to that data,
+ and stores the 4-bit version in every cacheline of the object. Hardware
+ saves the latter in spare bits in the cache and memory hierarchy. On each
+ load and store, the processor compares the upper 4 VA (virtual address) bits
+ to the cacheline's version. If there is a mismatch, the processor generates
+ a version mismatch trap which can be either precise or disrupting.
+ The trap is an error condition which the kernel delivers to the process
+ as a SIGSEGV signal.
+
+ The upper 4 bits of the VA represent a version and are not part of the
+ true address. The processor clears these bits and sign extends bit 59
+ to generate the true address.
+
+ Note that 32-bit applications cannot use ADI. */
