Merge branch 'x86-mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 MPX support from Thomas Gleixner: "This enables support for x86 MPX. MPX is a new debug feature for bound checking in user space. It requires kernel support to handle the bound tables and decode the bound violating instruction in the trap handler" * 'x86-mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: asm-generic: Remove asm-generic arch_bprm_mm_init() mm: Make arch_unmap()/bprm_mm_init() available to all architectures x86: Cleanly separate use of asm-generic/mm_hooks.h x86 mpx: Change return type of get_reg_offset() fs: Do not include mpx.h in exec.c x86, mpx: Add documentation on Intel MPX x86, mpx: Cleanup unused bound tables x86, mpx: On-demand kernel allocation of bounds tables x86, mpx: Decode MPX instruction to get bound violation information x86, mpx: Add MPX-specific mmap interface x86, mpx: Introduce VM_MPX to indicate that a VMA is MPX specific x86, mpx: Add MPX to disabled features ia64: Sync struct siginfo with general version mips: Sync struct siginfo with general version mpx: Extend siginfo structure to include bound violation information x86, mpx: Rename cfg_reg_u and status_reg x86: mpx: Give bndX registers actual names x86: Remove arbitrary instruction size limit in instruction decoder
