Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:

- An improvement from Ard Biesheuvel, who noted that the identity map
setup was taking a long time due to flush_cache_louis().

- Update a comment about dma_ops from Wolfram Sang.

- Remove use of "-p" with ld, where this flag has been a no-op since
2004.

- Remove the printing of the virtual memory layout, which is no longer
useful since we hide pointers.

- Correct SCU help text.

- Remove legacy TWD registration method.

- Add pgprot_device() implementation for mapping PCI sysfs resource
files.

- Initialise PFN limits earlier for kmemleak.

- Fix argument count to match macro definition (affects clang builds)

- Use unified assembler language almost everywhere for clang, and other
clang improvements (from Stefan Agner, Nathan Chancellor).

- Support security extension for noMMU and other noMMU cleanups (from
Vladimir Murzin).

- Remove unnecessary SMP bringup code (which was incorrectly copy'n'
pasted from the ARM platform implementations) and remove it from the
arch code to discourge further copys of it appearing.

- Add Cortex A9 erratum preventing kexec working on some SoCs.

- AMBA bus identification updates from Mike Leach.

- More use of raw spinlocks to avoid -RT kernel issues (from Yang Shi
and Sebastian Andrzej Siewior).

- MCPM hyp/svc mode mismatch fixes from Marek Szyprowski.

ARM: 8830/1: NOMMU: Toggle only bits in EXC_RETURN we are really care of

ARMv8M introduces support for Security extension to M class, among
other things it affects exception handling, especially, encoding of
EXC_RETURN.

The new bits have been added:

Bit [6] Secure or Non-secure stack
Bit [5] Default callee register stacking
Bit [0] Exception Secure

which conflicts with hard-coded value of EXC_RETURN:

In fact, we only care of few bits:

Bit [3] Mode (0 - Handler, 1 - Thread)
Bit [2] Stack pointer selection (0 - Main, 1 - Process)

We can toggle only those bits and left other bits as they were on
exception entry.

It is basically, what patch does - saves EXC_RETURN when we do
transition form Thread to Handler mode (it is first svc), so later
saved value is used instead of EXC_RET_THREADMODE_PROCESSSTACK.

ARM: 8757/1: NOMMU: Support PMSAv8 MPU

ARMv8R/M architecture defines new memory protection scheme - PMSAv8
which is not compatible with PMSAv7.

Key differences to PMSAv7 are:
- Region geometry is defined by base and limit addresses
- Addresses need to be either 32 or 64 byte aligned
- No region priority due to overlapping regions are not allowed
- It is unified, i.e. no distinction between data/instruction regions
- Memory attributes are controlled via MAIR

This patch implements support for PMSAv8 MPU defined by ARMv8R/M
architecture.
