207f583d71 [PARISC] fix crash in flush_icache_page_asm on PA1.1
As pointed out by serveral people, PA1.1 only has a type 26 instruction
meaning that the space register must be explicitly encoded.  Not giving an
explicit space means that the compiler uses the type 24 version which is PA2.0
only resulting in an illegal instruction crash.

This regression was caused by

f25e918e35 m68k: Setup CROSS_COMPILE at the top
CROSS_COMPILE must be setup before using e.g. cc-option (and a few other
as-*, cc-*, ld-* macros), else they will check against the wrong compiler
when cross-compiling, and may invoke the cross compiler with wrong or
suboptimal compiler options.

5e185581d7 [PARISC] fix PA1.1 oops on boot
All PA1.1 systems have been oopsing on boot since

commit f311847c2f
Author: James Bottomley <James.Bottomley@HansenPartnership.com>
Date:   Wed Dec 22 10:22:11 2010 -0600

    parisc: flush pages through tmpalias space

because a PA2.0 instruction was accidentally introduced into the PA1.1 TLB
insertion interruption path when it was consolidated with the do_alias macro.
Fix the do_alias macro only to use PA2.0 instructions if compiled for 64 bit.

867aae6ebe x86/PCI: only check for spinlock being held in SMP kernels
spin_is_locked() is always false on UP kernels: spin_lock_irqsave() does no
locking, so we can't tell whether the lock is held or not.  Therefore,
this warning is only valid for SMP kernels.

1b35a57b1c sparc32: Kill off software 32-bit multiply/divide routines.
For the explicit calls to .udiv/.umul in assembler, I made a
mechanical (read as: safe) transformation.  I didn't attempt
to make any simplifications.

In particular, __ndelay and __udelay can be simplified significantly.
Some of the %y reads are unnecessary and these routines have no need
any longer for allocating a register window, they can be leaf
functions.

fce2447627 C6X: add support to build with BINFMT_ELF_FDPIC
C6x userspace supports a shared library mechanism called DSBT for systems with
no MMU. DSBT is similar to FDPIC in allowing shared text segments and private
copies of data segments without an MMU. Both methods access data using a base
register and offset. With FDPIC, the caller of an external function sets up the
base register for the callee. With DSBT, the called function sets up its own
base register. Other details differ but both userspaces need the same thing
from the kernel loader: a map of where each ELF segment was loaded. The FDPIC
loader already provides this, so DSBT just uses it.

This patch enables BINFMT_ELF_FDPIC by default for C6X and provides the
necessary architecture hooks for the generic loader.

dad1743e59 x86/mce: Only restart instruction after machine check recovery if it is safe
Section 15.3.1.2 of the software developer manual has this to say about the
RIPV bit in the IA32_MCG_STATUS register:

  RIPV (restart IP valid) flag, bit 0 — Indicates (when set) that program
  execution can be restarted reliably at the instruction pointed to by the
  instruction pointer pushed on the stack when the machine-check exception
  is generated.  When clear, the program cannot be reliably restarted at
  the pushed instruction pointer.

We need to save the state of this bit in do_machine_check() and use it
in mce_notify_process() to force a signal; even if memory_failure() says
it made a complete recovery ... e.g. replaced a clean LRU page.

 2)	Changes to make rcu_barrier() avoid disrupting execution of CPUs
	that have no RCU callbacks.  Posted to LKML:
	https://lkml.org/lkml/2012/4/23/322.

 3)	A couple of commits that improve the efficiency of the interaction
	between preemptible RCU and the scheduler, these two being all
	that survived an abortive attempt to allow preemptible RCU's
	__rcu_read_lock() to be inlined.  The full set was posted to

This eliminated most of the remaining users of btfixup.

There are some complications because of the special cases we
have for sun4d, leon, and some flavors of viking.

It was found that there are no cases where a flush_page_for_dma
method was not hooked up to something, so the "noflush" iommu
methods were removed.

Add some documentation to the viking_sun4d_smp_ops to describe exactly
the hardware bug which causes us to need special TLB flushing on

d894d964ff sparc32: Convert mmu_* interfaces from btfixup to method ops.
This set of changes displays one major danger of btfixup, interface
signatures are not always type checked fully.  As seen here the iounit
variant of the map_dma_area routine had an incorrect type for one of
it's arguments.

It turns out to be harmless in this case, but just imagine trying to
debug something involving this kind of problem.  No thanks.

679bea5e43 sparc: Kill mmu_{un,}lockarea().
These were used on sun4c during floppy data transfers since on that
chip we had to lock the cpu mappings into the TLB because we cannot
take a TLB miss during the assembler floppy interrupt handler that
does the data transfer.

That is no longer necessary since we've removed sun4c support, thus
this stuff can disappear completely.

daeb4c0c3b ARM: PCI: get rid of pci_std_swizzle()
Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)

Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.

This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

Commit 069d4e743 ("ARM: EXYNOS4: Remove clock event timers using

to use MCT as event source. However MCT is not operating properly
on early revision of EXYNOS4 SoCs. All UniversalC210 boards are
based on it, so that commit broke support for it. This patch
provides a workaround that enables UniversalC210 boards to boot
again. s5p-timer is used as an event source, it works only for
non-SMP builds.

173bf69a7a ARM / mach-shmobile: Use preset_lpj with calibrate_delay()
Update the mach-shmobile shared delay calibration code for late
timers. All existing in-tree non-DT socs are however using early
timers today and they are unaffected by this change.

The patch modifies shmobile_setup_delay() from using lpj_fine
to preset_lpj. This change allows us to preset the worst case
loops-per-jiffy value to all CPU cores on the system.

The old code which made use of lpj_fine did not affect the
secondary CPU cores which made it impossible to boot on SMP
without early timers.

Needed for SMP SoCs using late timers like EMEV2 or any other
mach-shmobile SMP SoC that makes use of late timers via DT.

d6720003c3 ARM / mach-shmobile: sh73a0 SMP TWD boot regression fix
Fix SMP TWD boot regression on sh73a0 based platforms caused by:

4200b16 ARM: shmobile: convert to twd_local_timer_register() interface

After the merge of the above commit it has been impossible to boot
sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The
kernel crashes at smp_init_cpus() timing which is before the console
has been initialized, so to the user this looks like a kernel lock up
without any particular error message.

This patch fixes the regression on sh73a0 by moving the TWD
registration code from smp_init_cpus() to sys_timer->init() time.

This patch removed shmobile_twd_init() which is no longer needed

This was rather amusing, we were setting the btfixup vectors
based upon cpu type but all to the same exact generic srmmu

Furthermore, we were inconsistently marking the fixup as
either BTFIXUPCALL_SWAPO0G0 or BTFIXUPCALL_NORM.

998de4acb2 ARM: 7417/1: vfp: ensure preemption is disabled when enabling VFP access
The vfp_enable function enables access to the VFP co-processor register
space (cp10 and cp11) on the current CPU and must be called with
preemption disabled. Unfortunately, the vfp_init late initcall does not
disable preemption and can lead to an oops during boot if thread
migration occurs at the wrong time and we end up attempting to access
the FPSID on a CPU with VFP access disabled.

This patch fixes the initcall to call vfp_enable from a non-preemptible
context on each CPU and adds a BUG_ON(preemptible) to ensure that any
similar problems are easily spotted in the future.

Machines with sun4c support are very rare these days, and noone
is using them for any practical purposes.
The sun4c support has been know broken for quite some time too.

So rather than trying to keep it up-to-date, lets get rid of it.
This allows us to do some very welcome cleanup of sparc32 support.

for sun4m UP) to be a generic UP NMI.

7c0482e3d0 powerpc/irq: Fix another case of lazy IRQ state getting out of sync
So we have another case of paca->irq_happened getting out of
sync with the HW irq state. This can happen when a perfmon
interrupt occurs while soft disabled, as it will return to a
soft disabled but hard enabled context while leaving a stale
PACA_IRQ_HARD_DIS flag set.

This patch fixes it, and also adds a test for the condition
of those flags being out of sync in arch_local_irq_restore()
when CONFIG_TRACE_IRQFLAGS is enabled.

This helps catching those gremlins faster (and so far I
can't seem see any anymore, so that's good news).

c97d9320c6 ARM: msm: Drop useless teq from DEBUG_LL support
This teq was first introduced in bcc0f6a ([ARM] msm: clean up
iomap and devices, 2008-09-10). It seems that DEBUG_LL support on
MSM at the time had to remove the virtual mapping for the uart
base. Thus when the MMU was enabled the addruart macro returned 0
and the senduart macro would test for 0 and do nothing. It was a
simple way to turn off DEBUG_LL when the MMU was enabled.

The virtual mapping was added back in 6339f66 (msm: make
debugging UART (for DEBUG_LL) configurable, 2009-11-02) but the
patch forgot to remove the teq here. So as it stands the teq has
been useless for two years and DEBUG_LL works fine without it.

45de6767dc KEYS: Use the compat keyctl() syscall wrapper on Sparc64 for Sparc32 compat
Use the 32-bit compat keyctl() syscall wrapper on Sparc64 for Sparc32 binary
compatibility.

Without this, keyctl(KEYCTL_INSTANTIATE_IOV) is liable to malfunction as it
uses an iovec array read from userspace - though the kernel should survive this
as it checks pointers and sizes anyway.

I think all the other keyctl() function should just work, provided (a) the top
32-bits of each 64-bit argument register are cleared prior to invoking the
syscall routine, and the 32-bit address space is right at the 0-end of the
64-bit address space.  Most of the arguments are 32-bit anyway, and so for
those clearing is not required.

d60b9c16d7 Merge branch 'parisc' (PA-RISC compile fixes)
Merge PA-RISC compile fixes from Rolf Eike Beer:
 "Since commit d66acc39c7 ("bitops: Optimise get_order()") getorder.h
  includes log2.h which leads to an include loop on PA-RISC, bringing a
  bunch of other breakage to light.  This patchset fixes the compilation
  of the current state of 3.4 on HPPA.

  Unchanged against the first version, just added an Ack by Grant."

4a8a0788a3 parisc: move definition of PAGE0 to asm/page.h
This was defined in asm/pdc.h which needs to include asm/page.h for
__PAGE_OFFSET. This leads to an include loop so that page.h eventually will
include pdc.h again. While this is no problem because of header guards, it is
a problem because some symbols may be undefined. Such an error is this:

a5a737e090 sparc64: Do not clobber %g2 in xcall_fetch_glob_regs().
%g2 is meant to hold the CPUID number throughout this routine, since
at the very beginning, and at the very end, we use %g2 to calculate
indexes into per-cpu arrays.

However we erroneously clobber it in order to hold the %cwp register
value mid-stream.

Fix this code to use %g3 for the %cwp read and related calulcations
instead.

1fdc08abfa ARM: decompressor: avoid speculative prefetch from non-RAM areas
We setup identity MMU mappings across the entire 4GB of space, which
are permissionless because the domain is set to manager.

This unfortunately allows ARMv6 and later CPUs to speculatively
prefetch from the entire address space, which can cause undesirable
side effects if those regions contain devices.

As we setup the mappings with read/write permission, we can switch
the domain to client mode, and then use the XN bit for ARMv6 and
above to control speculative prefetch to non-RAM areas.

aa6f079075 sparc: fix build fail in mm/init_64.c when NEED_MULTIPLE_NODES is off
Commit 625d693e97 (linux-next)

    "sparc64: Convert over to NO_BOOTMEM."

causes the following compile failure for sparc64 allnoconfig:

  arch/sparc/mm/init_64.c:822:16: error: unused variable 'paddr'
  arch/sparc/mm/init_64.c:1759:7: error: unused variable 'node'
  arch/sparc/mm/init_64.c:809:12: error: 'memblock_nid_range' defined but not used

The paddr decl can easily be shuffled within the ifdef.  The
memblock_nid_range is just a stub function for when NEED_MULTIPLE_NODES
is off, but the only caller is within a NEED_MULTIPLE_NODES enabled
section, so we can simply delete it.

The unused "node" is slightly more interesting.  In the case of
"# CONFIG_NEED_MULTIPLE_NODES is not set" we no longer get the
definition of:

 #define NODE_DATA(nid)          (node_data[nid])

from arch/sparc/include/asm/mmzone.h - but instead we get:

 #define NODE_DATA(nid)          (&contig_page_data)

from include/linux/mmzone.h -- and since the arg is ignored,
the thing really is unused.  Rather than put in a confusing
looking __maybe_unused, simply splitting the declaration
from the assignment seemed to me to be the least offensive.

If the igep0030 module isn't connected to a display, no DSI or DPI
display will be specified in board code, and the DSS driver won't enable

d723c17ab6 ARM: OMAP2+: remove incorrect irq_chip ack field
Each irq_chip for the main interrupt controller has offsets set for irq
masking registers, which added to respective base results in a pointer
to appropriate hardware register. However this is not correct for
INTC_CONTROL as there is only one INTC_CONTROL register. This does not
cause problems because generic ack code is never called, but remove
this assignment to avoid confusion.

  There is still one patch that touches arch/arm/mach-ux500 too
  though (but it should merge fine with the other ux500 stuff).

  The changes to the device tree are of course dependent on some
  core changes and some patching in the GPIO/pin driver, but as
  the device tree files are believed to be a different world
  (and should one day live in their own git) I split this off
  anyway. I don't think people bisect the device trees per se
  and the board code in conjunction anyway.

48bfdb216e Merge branch 'depends/i2c/lpc32xx' into next/dt
As a prerequisite for merging the lpc32xx DT changes, this
pulls in the depends/i2c/lpc32xx branch that contains
changes to the pnx-i2c driver, which are already in the
i2c tree. The branch is available also on

   git://git.antcom.de/linux-2.6.git lpc32xx/i2c

Roland Stigge <stigge@antcom.de> writes:

 this is the series of the 4 patches adding device tree support to i2c-pnx
 (used by LPC32xx) that Wolfram Sang already applied to the i2c subsystem.
 Since both drivers/i2c/ and mach-lpc32xx are touched here, there will
 probably be conflicts that you need to be aware of.

 I'm posting this again for arm-soc since the actual mach-lpc32xx specific
 DT conversion builds upon those changes (see next pull request), especially
 in arch/arm/mach-lpc32xx/common.c.

 Wolfram already gave permission to merge this via arm-soc, but please
 coordinate and tell me if I can help resolving this.

Further, this implicitly updates the next/dt branch to v3.4-rc4, which
causes a trivial conflict from a change in one branch in code that
gets removed in another.

This is a rebased version of parts of

which was accidentally based on the linux-next tree and mixed too
many different things. The pinctrl related changes from the same

There are a few non-DT cleanups mixed in here, but fundamentally
it's all related to the DT conversion.

e4a9e94cc5 OMAPDSS: DSI: implement generic DSI pin config
In preparation for device tree, this patch changes how the DSI pins are
configured. The current configuration method is only doable with board
files and the configuration data is OMAP specific.

This patch moves the configuration data to the panel's platform data,
and the data can easily be given via DT in the future. The configuration
data format is also changed to a generic one which should be suitable
for all platforms.

The new format is an array of pin numbers, where the array items start
from clock + and -, then data1 + and -, and so on. For example:

{
	0,	// pin num for clock lane +
	1,	// pin num for clock lane -
	2,	// pin num for data1 lane +
	3,	// pin num for data1 lane -
	...
}

The pin numbers are translated by the DSI driver and used to configure
the hardware appropriately.

56dfa7fa19 powerpc/irq: Fix bug with new lazy IRQ handling code
We had a case where we could turn on hard interrupts while
leaving the PACA_IRQ_HARD_DIS bit set in the PACA. This can
in turn cause a BUG_ON() to hit in __check_irq_replay() due
to interrupt state getting out of sync.

The assembly code was also way too convoluted. Instead, we
now leave it to the C code to do the right thing which ends
up being smaller and more readable.
