Ben Dooks 251019fb97 ARM: 7650/1: mm: replace direct access to mm->context.id with new macro
The mmid macro is meant to be used to get the mm->context.id data
from the mm structure, but it seems to have been missed in a cuple
of files.

Ben Dooks 9520a5bece ARM: 7649/1: mm: mm->context.id fix for big-endian
Since the new ASID code in b5466f8728
("ARM: mm: remove IPI broadcasting on ASID rollover") was changed to
use 64bit operations it has broken the BE operation due to an issue
with the MM code accessing sub-fields of mm->context.id.

When running in BE mode we see the values in mm->context.id are stored
with the highest value first, so the LDR in the arch/arm/mm/proc-macros.S
reads the wrong part of this field. To resolve this, change the LDR in
the mmid macro to load from +4.

Thierry Reding 352af7d4dd ARM: 7648/1: pci: Allow passing per-controller private data
In order to allow drivers to specify private data for each controller,
this commit adds a private_data field to the struct hw_pci. This field
is an array of nr_controllers pointers that will be used to initialize
the private_data field of the corresponding controller's pci_sys_data
structure.

Joonsoo Kim 101eeda38c ARM: 7646/1: mm: use static_vm for managing static mapped areas
A static mapped area is ARM-specific, so it is better not to use
generic vmalloc data structure, that is, vmlist and vmlist_lock
for managing static mapped area. And it causes some needless overhead and
reducing this overhead is better idea.

Now, we have newly introduced static_vm infrastructure.
With it, we don't need to iterate all mapped areas. Instead, we just
iterate static mapped areas. It helps to reduce an overhead of finding
matched area. And architecture dependency on vmalloc layer is removed,
so it will help to maintainability for vmalloc layer.

Joonsoo Kim ed8fd2186a ARM: 7645/1: ioremap: introduce an infrastructure for static mapped area
In current implementation, we used ARM-specific flag, that is,
VM_ARM_STATIC_MAPPING, for distinguishing ARM specific static mapped area.
The purpose of static mapped area is to re-use static mapped area when
entire physical address range of the ioremap request can be covered
by this area.

This implementation causes needless overhead for some cases.
For example, assume that there is only one static mapped area and
vmlist has 300 areas. Every time we call ioremap, we check 300 areas for
deciding whether it is matched or not. Moreover, even if there is
no static mapped area and vmlist has 300 areas, every time we call
ioremap, we check 300 areas in now.

If we construct a extra list for static mapped area, we can eliminate
above mentioned overhead.
With a extra list, if there is one static mapped area,
we just check only one area and proceed next operation quickly.

In fact, it is not a critical problem, because ioremap is not frequently
used. But reducing overhead is better idea.

Another reason for doing this work is for removing architecture dependency
on vmalloc layer. I think that vmlist and vmlist_lock is internal data
structure for vmalloc layer. Some codes for debugging and stat inevitably
use vmlist and vmlist_lock. But it is preferable that they are used
as least as possible in outside of vmalloc.c

Now, I introduce an ARM-specific infrastructure for static mapped area. In
the following patch, we will use this and resolve above mentioned problem.

Linus Walleij e3e92a7be6 ARM: 7635/1: versatile: fix the PCI IRQ regression
The PCI IRQs were regressing due to two things:

- The PCI glue layer was using an hard-coded IRQ 27 offset.
  This caused the immediate regression.

- The SIC IRQ mask was inverted (i.e. a bit was indeed set to
  one for each valid IRQ on the SIC, but accidentally inverted
  in the init call). This has been around forever, but we have
  been saved by some other forgiving code that would reserve
  IRQ descriptors in this range, as the versatile is
  non-sparse.

When the IRQs were bumped up 32 steps so as to avoid using IRQ
zero and avoid touching the 16 legacy IRQs, things broke.

Introduce an explicit valid mask for the IRQs that are active
on the PIC/SIC, and pass that. Use the BIT() macro from
<linux/bitops.h> to make sure we hit the right bits, readily
defined in <mach/platform.h>.

When unlocking a spinlock, all we need to do is increment the owner
field of the lock. Since only one CPU can be performing an unlock()
operation for a given lock, this doesn't need to be exclusive.

This patch simplifies arch_spin_unlock to use non-exclusive accesses
when updating the owner field of the lock.

Dave Martin 638591cd7b ARM: 7626/1: arm/crypto: Make asm SHA-1 and AES code Thumb-2 compatible
This patch fixes aes-armv4.S and sha1-armv4-large.S to work
natively in Thumb.  This allows ARM/Thumb interworking workarounds
to be removed.

I also take the opportunity to convert some explicit assembler
directives for exported functions to the standard
ENTRY()/ENDPROC().

For the code itself:

  * In sha1_block_data_order, use of TEQ with sp is deprecated in
    ARMv7 and not supported in Thumb.  For the branches back to
    .L_00_15 and .L_40_59, the TEQ is converted to a CMP, under the
    assumption that clobbering the C flag here will not cause
    incorrect behaviour.

    For the first branch back to .L_20_39_or_60_79 the C flag is
    important, so sp is moved temporarily into another register so
    that TEQ can be used for the comparison.

  * In the AES code, most forms of register-indexed addressing with
    shifts and rotates are not permitted for loads and stores in
    Thumb, so the address calculation is done using a separate
    instruction for the Thumb case.

The resulting code is unlikely to be optimally scheduled, but it
should not have a large impact given the overall size of the code.
I haven't run any benchmarks.

Linus Torvalds 974b33586b ARM: arm-soc fixes for 3.8-rc
People are back from the holiday breaks, and it shows. Here are a bunch of
 fixes for a number of platforms:
  - A couple of small fixes for Nomadik
  - A larger set of changes for kirkwood/mvebu
    - uart driver selection, dt clocks, gpio-poweroff fixups,
      a few __init annotation fixes and some error handling improvement
      in their xor dma driver.
  - i.MX had a couple of minor fixes (and a critical one for flexcan2
    clock setup)
  - MXS has a small board fix and a framebuffer bugfix
  - A set of fixes for Samsung Exynos, fixing default bootargs and some
    Exynos5440 clock issues
  - A set of OMAP changes including PM fixes and a few sparse warning
    fixups
 
 All in all a bit more positive code delta than we'd ideally want to see
 here, mostly from the OMAP PM changes, but nothing overly crazy.

Rob Herring 0b3455a71e ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

Thomas Petazzoni 77916519cb arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces
We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and
MV78460. In fact, this is not true, and the MV78230 has only three
Ethernet interfaces.

So, the definitions of the Ethernet interfaces is now done as follows:

 * armada-370-xp.dtsi: definitions of the first two interfaces, that
   are common to Armada 370 and Armada XP

 * armada-xp.dtsi: definition of the third interface, common to all
   Armada XP variants.

 * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of
   the fourth interface.

The UART controller used in the Armada 370 and Armada XP SoCs is the
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
improper use of the ns16550 can lead to a kernel oops during boot if
a character is sent to the UART before the initialization of the
driver. The DW APB has an extra interrupt that gets raised when
writing to the LCR when busy. This explains why we need to use
dw-apb-uart driver to handle this.
