Russell King 57ca654bef ARM: ensure delay timer has sufficient accuracy for delays
We have recently had an example of someone wanting to use a 90kHz timer
for the software delay loop.

udelay() needs to have at least microsecond resolution to allow drivers
access to a delay mechanism with a reasonable chance of delaying the
period they requested within at least a 50% marging of error, especially
for small delays.

Discussion about the udelay() accuracy can be found at:
	https://lkml.org/lkml/2011/1/9/37

Reject timers which are unable to supply this level of resolution.

Switch ARM to use the generic show_mem() implementation, which displays
the statistics from the mm zone rather than walking the page arrays.

Russell King a6d7467898 ARM: proc-v7: avoid errata 430973 workaround for non-Cortex A8 CPUs
Avoid the errata 430973 workaround for non-Cortex A8 CPUs.  Having this
workaround enabled introduces an additional branch target buffer flush
into the context switching path, something we wish to avoid.  To allow
this errata to be enabled in multiplatform kernels while reducing its
impact, rearrange the Cortex-A8 CPU support to avoid impacting on other
Version 7 CPUs.

Russell King e5a5de4447 ARM: enable ARM errata 643719 workaround by default
The effects of not having ARM errata 643719 enabled on affected CPUs
can be very confusing and hard to debug.  Rather than leave this to
chance, enable this workaround by default.  Now that we have rearranged
the code, it should have a low impact on the majority of CPUs.

Russell King aaf4b5d92c ARM: cache-v7: optimise test for Cortex A9 r0pX devices
Eliminate one unnecessary instruction from this test by pre-shifting
the Cortex A9 ID - we can shift the actual ID in the teq instruction
thereby losing the pX bit of the ID at no cost.

Optimise the branches such that for the majority of unaffected devices,

Russell King cd8b24d9e8 ARM: cache-v7: consolidate initialisation of cache level index
Both v7_flush_cache_louis and v7_flush_dcache_all both begin the
flush_levels loop with r10 initialised to zero.  In each case, this
is done immediately prior to entering the loop.  Branch to this
instruction in v7_flush_dcache_all from v7_flush_cache_louis and
eliminate the unnecessary initialisation in v7_flush_cache_louis.

Russell King 47b8484ea6 ARM: cache-v7: shift CLIDR to extract appropriate field before masking
Rather than have code which masks and then shifts, such as:

	mrc     p15, 1, r0, c0, c0, 1
ALT_SMP(ands	r3, r0, #7 << 21)
ALT_UP( ands	r3, r0, #7 << 27)
ALT_SMP(mov	r3, r3, lsr #20)
ALT_UP(	mov	r3, r3, lsr #26)

re-arrange this as a shift and then mask.  The masking is the same for
each field which we want to extract, so this allows the mask to be
shared amongst code paths:

	mrc     p15, 1, r0, c0, c0, 1
ALT_SMP(mov	r3, r0, lsr #20)
ALT_UP(	mov	r3, r0, lsr #26)
	ands	r3, r3, #7 << 1

Use this method for the LoUIS, LoUU and LoC fields.

 this is based on earlier non-urgent fixes to avoid a non-trivial

Ard Biesheuvel 3abafaf219 crypto: arm - workaround for building with old binutils
Old versions of binutils (before 2.23) do not yet understand the
crypto-neon-fp-armv8 fpu instructions, and an attempt to build these
files results in a build failure:

arch/arm/crypto/aes-ce-core.S:133: Error: selected processor does not support ARM mode `vld1.8 {q10-q11},[ip]!'
arch/arm/crypto/aes-ce-core.S:133: Error: bad instruction `aese.8 q0,q8'
arch/arm/crypto/aes-ce-core.S:133: Error: bad instruction `aesmc.8 q0,q0'
arch/arm/crypto/aes-ce-core.S:133: Error: bad instruction `aese.8 q0,q9'
arch/arm/crypto/aes-ce-core.S:133: Error: bad instruction `aesmc.8 q0,q0'

Since the affected versions are still in widespread use, and this breaks
'allmodconfig' builds, we should try to at least get a successful kernel
build. Unfortunately, I could not come up with a way to make the Kconfig
symbol depend on the binutils version, which would be the nicest solution.

Instead, this patch uses the 'as-instr' Kbuild macro to find out whether
the support is present in the assembler, and otherwise emits a non-fatal
warning indicating which selected modules could not be built.

The sha256 assembly implementation can deal with all architecture levels
from ARMv4 to ARMv7-A, but not with ARMv7-M. Enabling it in an

Russell King 6c5c2a01fc ARM: proc-arm94*.S: fix setup function
Both ARM946 and ARM940 setup functions were corrupting r1 and r2,
which is not permissible - these are used to carry the machine ID
and boot data into the kernel, and must be preserved.

The code responsible for this was the same in both files: they were
using the registers to generate a protection region register value.

Fix this by turning this process into a macro, and using that macro
in both these files with an alternative register allocation.  r0,
r3 and r7 can be used for temporary values here.

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef
__KERNEL__ so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

Thomas Petazzoni 4f054d4451 ARM: mvebu: use 0xf1000000 as internal registers on Armada 370 DB
All Marvell EBU SoCs (Kirkwood, Dove, Orion, Armada) have the
capability of changing the location of their internal registers (i.e
the registers for most hardware blocks inside the SoC). When coming
out of reset, the internal registers are mapped at 0xd0000000, but
since years and years, the tradition has been to have the internal
registers remapped at 0xf1000000 by the bootloader, and Linux has
since then assumed that the internal registers for the SoC were
located at 0xf1000000 on Kirkwood, Dove, Orion, etc. Linux has never
been aware that those registers are remappable (and there is no way to
know where they are mapped at runtime, since the register to configure
the address of the registers is itself within the internal registers).

Then came the Armada 370 and Armada XP, in which some of the very
early silicon steppings had an issue, which forced to use 0xd0000000:
the SoC was no longer working properly when the internal registers
were remapped at 0xf1000000. This issue is only affecting very early
silicon steppings and production steppings are not affected: the issue
has been fixed in between.

Since what we (Free Electrons) used to do the initial submission of
the Armada 370 and Armada XP platforms was evaluation boards with
those very early steppings, we submitted Device Tree that assumed the
internal registers were mapped at 0xd0000000. This is the case for
Armada 370 DB, Armada XP DB and Armada XP GP.

However, in practice, since Marvell has been shipping the evaluation
boards with production steppings of the SoC, they are shipping those
boards with bootloaders that remap the registers to 0xf1000000. We
have already changed this internal register address to 0xf1000000 for
the Armada XP DB in commit 82066bdb5a and for the Armada XP GP in
commit 91ed32200e (both merged in v3.15).

We only recently got our hand on an Armada 370 DB with a production
stepping of the SoC, which uses a bootloader that remaps internal
registers at 0xf1000000. Therefore, this commit aligns the Armada 370
DB to be like the Armada XP DB and Armada XP GP: assume that the
internal registers are mapped at 0xf1000000.

We would like to stress out the fact that the usage of 0xd0000000 as
the internal register base address was a temporary workaround for
early steppings deficiencies, and that the real long-term solution is
the usage of 0xf1000000. Having 0xd0000000 is an *accident* in the
life of the Marvell platform support in the kernel, as is confirmed by
the usage of 0xf1000000 in all previous Marvell platforms (Dove,
Kirkwood, Orion).

There are unfortunately a number of commercial devices that continue
to use 0xd0000000 even though they use production steppings of the
SoC, simply because the vendors of such devices have never bothered
using a more recent bootloader version from Marvell. There is not much
we can do about it, and we plan on keeping 0xd0000000 in the Device
Tree of such devices.

The main reason for remapping the internal registers at 0xf1000000
instead of 0xd0000000 is that it leaves more space in the 0 -> 4 GB
part of the physical address space for RAM. With registers at
0xd0000000, all RAM between 0xd0000000 to 0xffffffff is lost because
it's covered by the I/O registers.

Russell King f6ac49ba29 ARM: vexpress: fix CPU hotplug with CT9x4 tile.
The Cortex A9 tile fails to unplug CPUs if errata 643719 is not enabled.
This leads to random weird behaviours, but ultimately seem to lock the
kernel one way or another when a CPU is hot unplugged.

Symptoms range from a spinlock lockup in the scheduler, the entire
system hanging, to dumping out the kernel printk buffer a few lines at
a time, and other weird behaviours.

This is caused by the outgoing CPU not having its inner caches properly
flushed before it exits coherency - flush_cache_louis() is used to
achieve this, but as a result of the hardware bug, this function ends
up doing nothing without the errata workaround enabled.

As the Versatile Express has an affected CPU, this errata must always
be enabled.

After 57a38effa5 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
the macb1 interface refuses to work properly because it tries
to cling to address 0 which isn't able to communicate in broadcast with
the mac anymore. The micrel phy on the board is actually configured
to show up at address 1.
Adding the phy node and its real address fixes the issue.

Olof Johansson efc98f7762 ARM: tegra: Device tree changes for v4.1-rc1
A bunch of changes to improve support on the Nyan Big (Acer Chromebook
 13). These enable the trackpad and make the WiFi card work. Changes to
 the userspace-exposed name of the soundcard are required for a better
 audio experience.
 
 Support for Nyan Blaze (HP Chromebook 14) is added. It is very similar
 to Nyan Big and therefore can enjoys many of the above improvements.
 
 Since the EMC driver can now be used to scale the frequency at which
 external memory is clocked, corresponding EMC frequency tables are added
 for Jetson TK1 and the Nyan boards.
 
 The Jetson TK1, Beaver and Nyan boards now also use generated pinmux
 data, which makes it easier to keep it in sync with the data provided by
 syseng.

 - Add device-tree support to the wlcore (wl12xx/wl18xx) driver.
 
 - Update the current users to use the bindings instead of pdata-quirks.
 
 - Finally, remove the deprecated wl12xx_platform_data struct
 
 Note that da850 board file code that still uses the platform data,
 but we have da850.dtsi that can be used instead. So it was decided
 that we should try to remove the wl12xx support from the da850
 board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
 the last patch in the series, the last patch can be simply reverted
 if needed.
 
 As this series touches quite a bit of arch code, it was suggested
 by Kalle Valo <kvalo@codeaurora.org> that the whole series should
 be merged via the arm-soc tree.

requirements that are not necessarily obvious to the uninitiated.
And from past code review experience, those were all initially
implemented badly.

After 3 years, it is time to refactor as much common code to the core
MCPM facility to make the backends as simple as possible.  To avoid a
flag day, the new scheme is introduced in parallel to the existing
backend interface.  When all backends are converted over, the
compatibility interface could be removed.

The new MCPM backend interface implements simpler methods addressing
very platform specific tasks performed under lock protection while
keeping the algorithmic complexity and race avoidance local to the
core code.
