Tony Lindgren 6ccc4c0ded ARM: OMAP3: Warn about spurious interrupts
In the case of spurious interrupt, the handler for previous interrupt
handler needs to flush posted writes with a read back of the interrupt
ack register. Warn about handlers that need to flush posted writes.

Paul Walmsley 64ce2907b1 ARM: OMAP2: skip unnecessary TLDR write during non-autoreload for gptimer
The GPTIMER TLDR register does not need to be written if the GPTIMER
is not in autoreload mode.  This is the usual case for dynamic tick-enabled
kernels.

Simulation data indicate that skipping the read that occurs as part of
the write should save at least 300-320 ns for each GPTIMER1 timer
reprogram.  (This assumes L4-Wakeup is at 19MHz and GPTIMER write
posting is enabled.)  Skipping the write itself probably won't have
much impact since it should be posted on the OCP interconnect.

Tested on 2430SDP and 3430SDP.

David Brownell e918edf7c2 ARM: OMAP: switch to gpio_direction_output
More conversion to the standard GPIO interfaces:  stop using
omap_set_gpio_direction() entirely, and switch over to the
gpio_direction_output() call.

Note that because gpio_direction_output() includes the initial
value, this change isn't quite transparent.

 - For the call sites which defined an initial value either
   before or after setting the direction, that value was used.

   When that value was previously assigned afterwards, this
   could eliminate a brief output glitch ... and possibly
   change behavior.  In a few cases (LCDs) several values
   were assigned together ... those were re-arranged to match
   the explicit sequence provided.

 - Some call sites didn't define such a value; so I chose an
   initial "off/reset" value that seemed to default to "off".

In short, files touched by this patch might notice some small
changes in startup behavior (with trivial fixes).

Russell King baa745a337 [ARM] Fix alignment fault handling for ARMv6 and later CPUs
On ARMv6 and later CPUs, it is possible for userspace processes to
get stuck on a misaligned load or store due to the "ignore fault"
setting; unlike previous CPUs, retrying the instruction without
the 'A' bit set does not always cause the load to succeed.

We have no real option but to default to fixing up alignment faults
on these CPUs, and having the CPU fix up those misaligned accesses
which it can.

Lennert Buytenhek 794baba637 [ARM] 5340/1: fix stack placement after noexecstack changes
Commit 8ec53663d2 ("[ARM] Improve
non-executable support") added support for detecting non-executable
stack binaries.  One of the things it does is to make READ_IMPLIES_EXEC
be set in ->personality if we are running on a CPU that doesn't support
the XN ("Execute Never") page table bit or if we are running a binary
that needs an executable stack.

This exposed a latent bug in ARM's asm/processor.h due to which we'll
end up placing the stack at a very low address, where it will bump into
the heap on any application that uses significant amount of stack or
heap or both, causing many interesting crashes.

Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead
of testing for equality against PER_LINUX_32BIT.

Commit 0c65f459ce intended to fix truncation issues with fls() on

However that didn't take into account the fact that __fls() already
already had different semantics in the kernel.

Let's move the __fls() code into fls() function directly, and redefine
__fls() with the appropriate semantics.  While at it, bring a generic

Eric Miao 067455aa53 [ARM] pxa: add support for additional GPIOs on PXA26x
Original patch from Marek Vasut, the problems with PXA26x are:

1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
   inverted in GPDR2, as well as their alternate function bits being
   '1' for their GPIO functionality in GAFRx

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.

__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

already have that variable, remove the unnecessary 'gpio_nr' now.

Also, fix the incorrect GPIO number passed in pxa27x_init_irq().

Note: pxa_last_gpio should be initialized earlier, and this is true
since it's been assigned in machine_desc->init_irq().

by passing the input signal through a 2-bit shift register clocked
by a 128Hz clock.

Stelian Pop 7be90a6ba9 [ARM] 5319/1: AT91: support AT91CAP9 revC CPUs
The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).

This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
	- activate a workaround for the external interrupts levels
	  (on revB CPUs)
	- set the UDPHS_BYPASS bit (on revB CPUs)
	- set AT91_GPBR register address to the correct offset
	  (0xfffffd50 on revB, 0xfffffd60 on revC)

For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.

This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.

class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

We used to override the copy_user_page() function.  However, this

highmem support, since we convert from a struct page to a kernel
direct mapped address and back to a struct page again.

Moreover, with highmem support, we end up pointlessly setting up
kmap entries for pages which we're going to remap.  So, push the
kmapping down into the copypage implementation files where it's
required.

Catalin Marinas 877d1f3389 RealView: Make more vmalloc space by changing IO_ADDRESS
Since boards like PB11MPCore have 512MB of RAM and 128MB of flash, the
virtual space is short on vmalloc memory and mapping the flash fails.
This patch changes the IO_ADDRESS so that static mappings start at
0xfc000000 and moves the PCI virtual addresses higher up. The new
VMALLOC_END is set to 0xf8000000 (512MB higher than the old value).

Russell King ebb4c65869 [ARM] iop: iop3xx needs registers mapped uncached+unbuffered
Mikael Pettersson reported:

   The 2.6.28-rc kernels fail to detect PCI device 0000:00:01.0
   (the first ethernet port) on my Thecus n2100 XScale box.

   There is however still a strange "ghost" device that gets partially
   detected in 2.6.28-rc2 vanilla.

The IOP321 manual says:

  The user designates the memory region containing the OCCDR as
  non-cacheable and non-bufferable from the IntelR XScaleTM core.
  This guarantees that all load/stores to the OCCDR are only of
  DWORD quantities.

Ensure that the OCCDR is so mapped.

Russell King ab4f2ee130 [ARM] fix naming of MODULE_START / MODULE_END
As of 73bdf0a60e, the kernel needs
to know where modules are located in the virtual address space.
On ARM, we located this region between MODULE_START and MODULE_END.
Unfortunately, everyone else calls it MODULES_VADDR and MODULES_END.
Update ARM to use the same naming, so is_vmalloc_or_module_addr()
can work properly.  Also update the comment on mm/vmalloc.c to
reflect that ARM also places modules in a separate region from the
vmalloc space.

However, on 34xx INTCPS_SIR_IRQ_OFFSET bits [31:7] also contains the
SPURIOUSIRQFLAG, which gets set if the interrupt sorting information
is invalid.

If the SPURIOUSIRQFLAG bits are not ignored, the interrupt code will
occasionally produce a bunch of confusing errors:

irq -33, desc: c02ddcc8, depth: 0, count: 0, unhandled: 0
->handle_irq():  c006f23c, handle_bad_irq+0x0/0x22c

Steven Rostedt 07c4cc1cda ftrace: disable dynamic ftrace for all archs that use daemon
The ftrace daemon is complex and can cause nasty races if something goes
wrong. Since it affects all of the kernel, this patch disables dynamic
ftrace from any arch that depends on the daemon. Until the archs are
ported over to the new MCOUNT_RECORD method, I am disabling dynamic
ftrace from them.

Note: I am leaving in the arch/<arch>/kernel/ftrace.c code alone since
that can be used when the arch is ported to MCOUNT_RECORD. To port
the arch to MCOUNT_RECORD, the scripts/recordmcount.pl needs to be
updated. I will make that easier to do for 2.6.29. For 28, we will keep
the archs disabled.

Nicolas Pitre 884afaab44 [ARM] 5320/1: fix assembly constraints in implementation of do_div()
Those inline assembly segments using the umlal instruction must have
the & modifier so to be sure that a purely input register won't alias
one of the registers used as input+output.  In most cases, the inputs
are still used after the outputs are touched, and most binutil versions
insist on "rdhi, rdlo and rm must all be different" even for ARMv6+.

David Brownell 085eefb594 [ARM] 5316/1: AT91: oops (regression) fix on gpio irq
From: David Brownell <dbrownell@users.sourceforge.net>

The "5298/1: Drop desc_handle_irq()" patch went overboard

Brian Swetland 1637de0c9b [ARM] msm: rename ARCH_MSM7X00A to ARCH_MSM
The MSM architecture covers a wider family of chips than just the MSM7X00A.
Move to a more generic name, in perparation for supporting the specific
SoC variants as sub-architectures (ARCH_MSM7X01A, ARCH_MSM722X, etc).  This
gives us ARCH_MSM for the (many) common peripherals.

This also removes the unused/obsolete config item MSM7X00A_IDLE.
