Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull second set of ARM changes from Russell King:
"This is the remainder of the ARM changes for this merge window.
Included in this request are:
- fixes for kprobes for big-endian support
- fix tracing in soft_restart
- avoid phys address overflow in kdump code
- fix reporting of read-only pmd bits in kernel page table dump
- remove unnecessary (and possibly buggy) call to outer_flush_all()
- fix a three sparse warnings (missing header file for function
prototypes)
- fix pj4 crashing single zImage (thanks to arm-soc merging changes
which enables this with knowledge that the corresponding fix had
not even been submitted for my tree before the merge window opened)
- vfp macro cleanups
- dump register state on undefined instruction userspace faults when
debugging"
* 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
Dump the registers on undefined instruction userspace faults
ARM: 8018/1: Add {inc,dec}_preempt_count asm macros
ARM: 8017/1: Move asm macro get_thread_info to asm/assembler.h
ARM: 8016/1: Check cpu id in pj4_cp0_init.
ARM: 8015/1: Add cpu_is_pj4 to distinguish PJ4 because it has some differences with V7
ARM: add missing system_misc.h include to process.c
ARM: 8009/1: dcscb.c: remove call to outer_flush_all()
ARM: 8014/1: mm: fix reporting of read-only PMD bits
ARM: 8012/1: kdump: Avoid overflow when converting pfn to physaddr
ARM: 8010/1: avoid tracers in soft_restart
ARM: kprobes-test: Workaround GAS .align bug
ARM: kprobes-test: use <asm/opcodes.h> for Thumb instruction building
ARM: kprobes-test: use <asm/opcodes.h> for ARM instruction building
ARM: kprobes-test: use <asm/opcodes.h> for instruction accesses
ARM: probes: fix instruction fetch order with <asm/opcodes.h>
