9fa8af91f0 ARM: dma-mapping: fix error path for memory allocation failure
This patch fixes incorrect check in error path. When the allocation of
first page fails, the kernel ops appears due to accessing -1 element of
the pages array.

e9da6e9905 ARM: dma-mapping: remove custom consistent dma region
This patch changes dma-mapping subsystem to use generic vmalloc areas
for all consistent dma allocations. This increases the total size limit
of the consistent allocations and removes platform hacks and a lot of
duplicated code.

Atomic allocations are served from special pool preallocated on boot,
because vmalloc areas cannot be reliably created in atomic context.

008c2e8f24 s390/mm: fix fault handling for page table walk case
Make sure the kernel does not incorrectly create a SIGBUS signal during
user space accesses:

For user space accesses in the switched addressing mode case the kernel
may walk page tables and access user address space via the kernel
mapping. If a page table entry is invalid the function __handle_fault()
gets called in order to emulate a page fault and trigger all the usual
actions like paging in a missing page etc. by calling handle_mm_fault().

If handle_mm_fault() returns with an error fixup handling is necessary.
For the switched addressing mode case all errors need to be mapped to
-EFAULT, so that the calling uaccess function can return -EFAULT to
user space.

Unfortunately the __handle_fault() incorrectly calls do_sigbus() if
VM_FAULT_SIGBUS is set. This however should only happen if a page fault
was triggered by a user space instruction. For kernel mode uaccesses
the correct action is to only return -EFAULT.
So user space may incorrectly see SIGBUS signals because of this bug.

For current machines this would only be possible for the switched
addressing mode case in conjunction with futex operations.

bac821a6e3 powerpc/ftrace: Trace function graph entry before updating index
As Colin Cross ported my x86 change to ARM, he also pointed out that
powerpc is also behind in this fix.

The commit 722b3c7469 "ftrace/graph: Trace function entry before
updating index" fixes an issue with function graph tracing for x86,
where if the called entry function decides not to trace interrupts, it
can fail the check if an interrupt comes in just after the
curr_ret_stack is updated.

The solution is to call the entry function first, then update the
curr_ret_stack if the entry function wants to be traced.

8ded2bbc18 posix_types.h: Cleanup stale __NFDBITS and related definitions
Recently, glibc made a change to suppress sign-conversion warnings in
FD_SET (glibc commit ceb9e56b3d1).  This uncovered an issue with the
kernel's definition of __NFDBITS if applications #include
<linux/types.h> after including <sys/select.h>.  A build failure would
be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2
flags to gcc.

It was suggested that the kernel should either match the glibc
definition of __NFDBITS or remove that entirely.  The current in-kernel
uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no
uses of the related __FDELT and __FDMASK defines.  Given that, we'll
continue the cleanup that was started with commit 8b3d1cda4f
("posix_types: Remove fd_set macros") and drop the remaining unused
macros.

Additionally, linux/time.h has similar macros defined that expand to
nothing so we'll remove those at the same time.

896c01cb4b powerpc/85xx: p1022ds: fix DIU/LBC switching with NAND enabled
In order for indirect mode on the PIXIS to work properly, both chip selects
need to be set to GPCM mode, otherwise writes to the chip select base
addresses will not actually post to the local bus -- they'll go to the
NAND controller instead.  Therefore, we need to set BR0 and BR1 to GPCM
mode before switching to indirect mode.

6269f2584a powerpc/85xx: p1022ds: disable the NAND flash node if video is enabled
The Freescale P1022 has a unique pin muxing "feature" where the DIU video
controller's video signals are muxed with 24 of the local bus address signals.
When the DIU is enabled, the bulk of the local bus is disabled, preventing
access to memory-mapped devices like NAND flash and the pixis FPGA.

Therefore, if the DIU is going to be enabled, then memory-mapped devices on
the localbus, like NAND flash, need to be disabled.

This patch is similar to "powerpc/85xx: p1022ds: disable the NOR flash node
if video is enabled", except that it disables the NAND flash node instead.
This PIXIS node needs to remain enabled because it is used by platform code
to switch into indirect mode.

a119365586 [IA64] Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts
The following build error occured during a ia64 build with
swap-over-NFS patches applied.

net/core/sock.c:274:36: error: initializer element is not constant
net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks')
net/core/sock.c:274:36: error: initializer element is not constant

This is identical to a parisc build error. Fengguang Wu, Mel Gorman
and James Bottomley did all the legwork to track the root cause of
the problem. This fix and entire commit log is shamelessly copied
from them with one extra detail to change a dubious runtime use of
ATOMIC_INIT() to atomic_set() in drivers/char/mspec.c

Dave Anglin says:
> Here is the line in sock.i:
>
> struct static_key memalloc_socks = ((struct static_key) { .enabled =
> ((atomic_t) { (0) }) });

The above line contains two compound literals.  It also uses a designated
initializer to initialize the field enabled.  A compound literal is not a
constant expression.

The location of the above statement isn't fully clear, but if a compound
literal occurs outside the body of a function, the initializer list must
consist of constant expressions.

new mm uses a 4 level page table, including the task size of 2<<42

cannot work at 40MHz with this CCB frequency, so we need to slow down the
clock rate of espi to 35MHz to make it work stable at the CCB frequency.

8143adafd2 s390/ipl: Use diagnose 8 command separation
Currently the vmcmd shutdown action is parsed by the kernel and
if multiple cp commands have been specified, they are issued
separately with the cpcmd() function.

The underlying diagnose 8 instruction already allows to specify
multiple commands that are separated by 0x15. The ASCEBC() function
used by cpcmd() translates '\n' to 0x15. The '\n' character is
currently used as vmcmd command separator and therefore the vmcmd
string can be passed directly to the cpcmd() function.

Using the diagnose 8 command separation has the advantage that also
after disruptive commands that stop Linux, for example "def store",
additional commands can be executed.

01ad8063a5 ARM: dt: tegra trimslice: add vbus-gpio property
On TrimSlice, Tegra's USB1 port may be routed to either an external micro
USB port, or an internal USB->SATA bridge for SSD or HDD. This muxing is
controlled by a GPIO. Whilst not strictly a VBUS GPIO, the TrimSlice
board files caused this GPIO to be set appropriately to enable the SATA
bridge by passing it as the VBUS GPIO to the USB driver. Echo this same
configuration in device tree to enable the SATA bridge.

An alternative might be to implement a full USB bus mux driver. However,
that seems over-complex right now.

b5409430ff ARM: Kirkwood: Fix PHY disable clk problems
Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.

This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.

However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.

Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate.  This is done by
adding a second function that may be used to enable the PHYs.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()

 can't be isolated are grouped together. This code is required for the
 upcoming VFIO framework.
 
 Another IOMMU-API change written by be is the introduction of domain
 attributes. This makes it easier to handle GART-like IOMMUs with the
 IOMMU-API because now the start-address and the size of the domain
 address space can be queried.
 
 Besides that there are a few cleanups and fixes for the NVidia Tegra
 IOMMU drivers and the reworked init-code for the AMD IOMMU. The later is
 from my patch-set to support interrupt remapping. The rest of this
 patch-set requires x86 changes which are not mergabe yet. So full
 support for interrupt remapping with AMD IOMMUs will come in a future
 merge window.

  * MCE polling driver to collect hypervisor MCE buffer and present them to

  * Physical CPU online/offline support. When an privileged guest is booted
    it is present with virtual CPUs, which might have an 1:1 to physical

    CPUs.
 Bug-fixes for:
  * Coverity found fixes in the console and ACPI processor driver.
  * PVonHVM kexec fixes along with some cleanups.
  * Pages that fall within E820 gaps and non-RAM regions (and had been

This patch was originally part of a 2-patch series. Patch 2 got applied

Merge tag 'kvm-3.6-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull KVM updates from Avi Kivity:
 "Highlights include
  - full big real mode emulation on pre-Westmere Intel hosts (can be
    disabled with emulate_invalid_guest_state=0)
  - relatively small ppc and s390 updates
  - PCID/INVPCID support in guests
  - EOI avoidance; 3.6 guests should perform better on 3.6 hosts on
    interrupt intensive workloads)
  - Lockless write faults during live migration
  - EPT accessed/dirty bits support for new Intel processors"

Fix up conflicts in:
 - Documentation/virtual/kvm/api.txt:

   Stupid subchapter numbering, added next to each other.

 - arch/powerpc/kvm/booke_interrupts.S:

   PPC asm changes clashing with the KVM fixes

 - arch/s390/include/asm/sigp.h, arch/s390/kvm/sigp.c:

   Duplicated commits through the kvm tree and the s390 tree, with
   subsequent edits in the KVM tree.
