Pull ARM updates from Russell King: - Print an un-hashed userspace PC on undefined instruction exception - Disable FDPIC ABI - Remove redundant vfp_flush/release_thread functions - Use raw_cpu_* rather than this_cpu_* in handle_bad_stack() - Avoid needlessly long backtraces when show_regs() is called - Fix an issue with stack traces through call_with_stack() - Avoid stack traces saving a duplicate exception PC value - Pass a void pointer to virt_to_page() in DMA mapping code - Fix kasan maps for modules when CONFIG_KASAN_VMALLOC=n - Show FDT region and page table level names in kernel page tables dump * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 9246/1: dump: show page table level name ARM: 9245/1: dump: show FDT region ARM: 9242/1: kasan: Only map modules if CONFIG_KASAN_VMALLOC=n ARM: 9240/1: dma-mapping: Pass (void *) to virt_to_page() ARM: 9234/1: stacktrace: Avoid duplicate saving of exception PC value ARM: 9233/1: stacktrace: Skip frame pointer boundary check for call_with_stack() ARM: 9224/1: Dump the stack traces based on the parameter 'regs' of show_regs() ARM: 9232/1: Replace this_cpu_* with raw_cpu_* in handle_bad_stack() ARM: 9228/1: vfp: kill vfp_flush/release_thread() ARM: 9226/1: disable FDPIC ABI ARM: 9221/1: traps: print un-hashed user pc on undefined instruction
