Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next
Pull sparc updates from David Miller: 1) Add support for ADI (Application Data Integrity) found in more recent sparc64 cpus. Essentially this is keyed based access to virtual memory, and if the key encoded in the virual address is wrong you get a trap. The mm changes were reviewed by Andrew Morton and others. Work by Khalid Aziz. 2) Validate DAX completion index range properly, from Rob Gardner. 3) Add proper Kconfig deps for DAX driver. From Guenter Roeck. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next: sparc64: Make atomic_xchg() an inline function rather than a macro. sparc64: Properly range check DAX completion index sparc: Make auxiliary vectors for ADI available on 32-bit as well sparc64: Oracle DAX driver depends on SPARC64 sparc64: Update signal delivery to use new helper functions sparc64: Add support for ADI (Application Data Integrity) mm: Allow arch code to override copy_highpage() mm: Clear arch specific VM flags on protection change mm: Add address parameter to arch_validate_prot() sparc64: Add auxiliary vectors to report platform ADI properties sparc64: Add handler for "Memory Corruption Detected" trap sparc64: Add HV fault type handlers for ADI related faults sparc64: Add support for ADI register fields, ASIs and traps mm, swap: Add infrastructure for saving page metadata on swap signals, sparc: Add signal codes for ADI violations
