Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - add arch/arm/Kbuild from Masahiro Yamada. - simplify act_mm macro, since it contains an open-coded get_thread_info. - VFP updates for Clang from Stefan Agner. - Fix unwinder for Clang from Nathan Huckleberry. - Remove unused it8152 PCI host controller, used by the removed cm-x2xx platforms from Mike Rapoport. - Further explanation of __range_ok(). - Remove kimage_voffset that isn't used anymore from Marc Zyngier. - Drop ancient Thumb-2 workaround for old binutils from Ard Biesheuvel. - Documentation cleanup for mach-* from Pete Zaitcev. * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8996/1: Documentation/Clean up the description of mach-<class> ARM: 8995/1: drop Thumb-2 workaround for ancient binutils ARM: 8994/1: mm: drop kimage_voffset which was only used by KVM ARM: uaccess: add further explanation of __range_ok() ARM: 8993/1: remove it8152 PCI controller driver ARM: 8992/1: Fix unwind_frame for clang-built kernels ARM: 8991/1: use VFP assembler mnemonics if available ARM: 8990/1: use VFP assembler mnemonics in register load/store macros ARM: 8989/1: use .fpu assembler directives instead of assembler arguments ARM: 8982/1: mm: Simplify act_mm macro ARM: 8981/1: add arch/arm/Kbuild

- help
- Various binutils versions can resolve Thumb-2 branches to
- locally-defined, preemptible global symbols as short-range "b.n"
- branch instructions.
-
- This is a problem, because there's no guarantee the final
- destination of the symbol, or any candidate locations for a
- trampoline, are within range of the branch. For this reason, the
- kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
- relocation in modules at all, and it makes little sense to add
- support.
-
- The symptom is that the kernel fails with an "unsupported
- relocation" error when loading some modules.
-
- Until fixed tools are available, passing
- -fno-optimize-sibling-calls to gcc should prevent gcc generating
- code which hits this problem, at the cost of a bit of extra runtime
- stack usage in some cases.
-
- The problem is described in more detail at:
- https://bugs.launchpad.net/binutils-linaro/+bug/725126
-
- Only Thumb-2 kernels are affected.
-
- Unless you are sure your tools don't have this problem, say Y.
