Russell King 4ae7806f8b [ARM] pxa: Don't wind OSCR backwards over suspend/resume
OSCR is supposed to monotonically increment; however restoring it
to a time prior to OSMR0 may result in it being wound backwards.
Instead, if OSMR0 is within the minimum expiry time, wind OSMR0
forwards.

Herbert Valerio Riedel 8f86dda3ed [ARM] Orion: implement power-off method for QNAP TS-109/209
Since the PIC is attached to UART1, it doesn't need a kernel device driver
of its own; but powering off is something that the kernel should do, so
this patch forcefully configures the UART1 for 19200 baud and sends the
character that tells the PIC to cut the power.

Nicolas Pitre 3ebb5a2b44 [ARM] add Feroceon support to compressed/head.S
The cache replacement policy on the Feroceon core doesn't guarantee
that reading through a linear chunk of memory flushes the entire cache.
This is however what the default method for ARMv5TE cores does.

Although the Feroceon is an ARMv5TE core, it implements the same
cache handling instructions as the ARMv5TEJ cores, and must use it for
proper cache flush.

Nicolas Pitre 15754bf98f [ARM] add ARMv5TEJ aware cache flush method to compressed/head.S
The default ARMv4 method consisting of reading through some memory
area isn't compatible with the cache replacement policy of some
ARMv5TEJ compatible cache implementations.  It is also a bit wasteful
when a dedicated instruction can do the needed work optimally.

It is hard to tell if all ARMv5TEJ cores will support the used CP15
instruction, but at least all those implementations Linux currently
knows about (ARM926 and ARM1026) do support it.

Tested on an OMAP1610 H2 target.

This patch is required, in conjunction with the patch submitted to

Without the patches, the boot log shows

physmap platform flash device: 00080000 at f0000000
...

whereas with the patches, the boot log shows

physmap platform flash device: 00080000 at f0000000

physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank

...

The change made by this patch is required because the ST M29W400DB

pin is high when the board is powered on).

This patch enables the use of the Advanced SIMD (NEON) extension on
ARMv7. The NEON technology is a 64/128-bit hybrid SIMD architecture
for accelerating the performance of multimedia and signal processing
applications. The extension shares the registers with the VFP unit and
enabling/disabling and saving/restoring follow the same rules. In
addition, there are instructions that do not have the appropriate CP
number encoded, the checks being made in the call_fpe function.

Catalin Marinas c98929c07a [ARM] 4582/2: Add support for the common VFP subarchitecture
This patch allows the VFP support code to run correctly on CPUs
compatible with the common VFP subarchitecture specification (Appendix
B in the ARM ARM v7-A and v7-R edition). It implements support for VFP
subarchitecture 2 while being backwards compatible with
subarchitecture 1.

On VFP subarchitecture 1, the arithmetic exceptions are asynchronous
(or imprecise as described in the old ARM ARM) unless the FPSCR.IXE
bit is 1. The exceptional instructions can be read from FPINST and
FPINST2 registers. With VFP subarchitecture 2, the arithmetic
exceptions can also be synchronous and marked by the FPEXC.DEX bit
(the FPEXC.EX bit is cleared). CPUs implementing the synchronous
arithmetic exceptions don't have the FPINST and FPINST2 registers and
accessing them would trigger and undefined exception.

Note that FPEXC.EX bit has an additional meaning on subarchitecture 1
- if it isn't set, there is no additional information in FPINST and
FPINST2 that needs to be saved at context switch or when lazy-loading
the VFP state of a different thread.

The patch also removes the clearing of the cumulative exception flags in
FPSCR when additional exceptions were raised. It is up to the user
application to clear these bits.

Herbert Valerio Riedel 7ca7225339 [ARM] 4669/1: ep93xx: simplify GPIO code and cleanups
This patch renumbers the (virtual) GPIO line numbering to have all
irq-capable gpio lines <= EP93XX_GPIO_LINE_MAX_IRQ by swapping the
port f range with the port c range; This simplifies code such as

 #define IRQ_EP93XX_GPIO(x)  (64 + (((x) + (((x) >> 2) & 8)) & 0x1f))

or

 if (line >= 0 && line < 16) {
    /* Port A/B */
 } else if (line >= 40 && line < 48) {
    /* Port F */
 }

considerably; in addition to the renumbering this patch also
introduces macro constants EP93XX_GPIO_LINE_MAX_IRQ and
EP93XX_GPIO_LINE_MAX, and replaces most magic numbers by those and
invocations of gpio_to_irq()/irq_to_gpio().

Linus Torvalds 38ad9aebe7 Fix ARM profiling/instrumentation configuration
Commit 09cadedbdc ("Combine
instrumentation menus in kernel/Kconfig.instrumentation") broke ARM
profiling support, since ARM has some extra Kconfig options and doesn't
just use the common OPROFILE/KPROBES config options.

Rather than just revert the thing outright, or add ARM-specific
knowledge to the generic Kconfig.instrumentation file (where the only
and whole point was to be generic, not too architecture-specific), this
just makes ARM not use the generic version, since it doesn't suit it.

So create an arm-specific version of Kconfig.instrumentation instead,
and use that.

Nicolas Pitre b49c0f24cf [ARM] 4659/1: remove possibilities for spurious false negative with __kuser_cmpxchg
The ARM __kuser_cmpxchg routine is meant to implement an atomic cmpxchg
in user space.  It however can produce spurious false negative if a
processor exception occurs in the middle of the operation.  Normally
this is not a problem since cmpxchg is typically called in a loop until
it succeeds to implement an atomic increment for example.

Some use cases which don't involve a loop require that the operation be
100% reliable though.  This patch changes the implementation so to
reattempt the operation after an exception has occurred in the critical
section rather than abort it.

Here's a simple program to test the fix (don't use CONFIG_NO_HZ in your
kernel as this depends on a sufficiently high interrupt rate):

	#include <stdio.h>

	typedef int (__kernel_cmpxchg_t)(int oldval, int newval, int *ptr);
	#define __kernel_cmpxchg (*(__kernel_cmpxchg_t *)0xffff0fc0)

	int main()
	{
		int i, x = 0;
		for (i = 0; i < 100000000; i++) {
			int v = x;
			if (__kernel_cmpxchg(v, v+1, &x))
				printf("failed at %d: %d vs %d\n", i, v, x);
		}
		printf("done with %d vs %d\n", i, x);
		return 0;
	}

Russell King 91bc51d8a1 [ARM] pxa: fix one-shot timer mode
One-shot timer mode on PXA has various bugs which prevent kernels
build with NO_HZ enabled booting.  They end up spinning on a
permanently asserted timer interrupt because we don't properly
clear it down - clearing the OIER bit does not stop the pending
interrupt status.  Fix this in the set_mode handler as well.

Moreover, the code which sets the next expiry point may race with
the hardware, and we might not set the match register sufficiently
in the future.  If we encounter that situation, return -ETIME so
the generic time code retries.

Serge E. Hallyn b460cbc581 pid namespaces: define is_global_init() and is_container_init()
is_init() is an ambiguous name for the pid==1 check.  Split it into
is_global_init() and is_container_init().

A cgroup init has it's tsk->pid == 1.

A global init also has it's tsk->pid == 1 and it's active pid namespace
is the init_pid_ns.  But rather than check the active pid namespace,
compare the task structure with 'init_pid_ns.child_reaper', which is
initialized during boot to the /sbin/init process and never changes.

Changelog:

	2.6.22-rc4-mm2-pidns1:
	- Use 'init_pid_ns.child_reaper' to determine if a given task is the
	  global init (/sbin/init) process. This would improve performance
	  and remove dependence on the task_pid().

	2.6.21-mm2-pidns2:

	- [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc,
	  ppc,avr32}/traps.c for the _exception() call to is_global_init().
	  This way, we kill only the cgroup if the cgroup's init has a
	  bug rather than force a kernel panic.

There is no reason why the .prepare() and .finish() methods in 'struct
platform_suspend_ops' should take any arguments, since architectures don't use
these methods' argument in any practically meaningful way (ie.  either the
target system sleep state is conveyed to the platform by .set_target(), or
there is only one suspend state supported and it is indicated to the PM core
by .valid(), or .prepare() and .finish() aren't defined at all).   There also
is no reason why .finish() should return any result.

reasonable to change it to 'struct platform_suspend_ops'.   In that case, the
name of the global variable of this type used by the PM core and the names of
related functions should be changed accordingly.

Rafael J. Wysocki 95d9ffbe01 PM: Move definition of struct pm_ops to suspend.h
Move the definition of 'struct pm_ops' and related functions from <linux/pm.h>
to <linux/suspend.h> .

There are, at least, the following reasons to do that:
* 'struct pm_ops' is specifically related to suspend and not to the power
  management in general.
* As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it
  causes the entire kernel to be recompiled, which is unnecessary and annoying.
* Some suspend-related features are already defined in <linux/suspend.h>, so it
  is logical to move the definition of 'struct pm_ops' into there.
* 'struct hibernation_ops', being the hibernation-related counterpart of
  'struct pm_ops', is defined in <linux/suspend.h> .

Will Schmidt dcca2bde4f During VM oom condition, kill all threads in process group
We have had complaints where a threaded application is left in a bad state
after one of it's threads is killed when we hit a VM: out_of_memory
condition.

Killing just one of the process threads can leave the application in a bad
state, whereas killing the entire process group would allow for the
application to restart, or be otherwise handled, and makes it very obvious
that something has gone wrong.

This change allows the entire process group to be taken down, rather
than just the one thread.

Russell King 3e0cc7ee04 [ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()
pxa_gpio_mode() is a universal call that fiddles with the GAFR
(gpio alternate function register.)  GAFR does not exist on PXA3
CPUs, but instead the alternate functions are controlled via the
MFP support code.

Platforms are expected to configure the MFP according to their
needs in their platform support code rather than drivers.  We
extend this idea to the GAFR, and make the gpio_direction_*()
functions purely operate on the GPIO level.

This means platform support code is entirely responsible for
configuring the GPIOs alternate functions on all PXA CPU types.

Lennert Buytenhek 1e621a8e37 [ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
Newer versions of binutils support --build-id, which adds an ELF
note section called ".note.gnu.build-id" to the output.  On the ARM
kernel build, because there is no explicit mention of this section
in the shipped ld script, this section is placed at vaddr 0x00000000
(whereas the normal kernel text/data typically starts at vaddr
0xc0008000), causing the output of objcopy (Image) to produce a 3G+
file.

This patch makes objcopy strip the .note.gnu.build-id section from
the Image file along with all other note sections, which fixes the
build.

Mike Westerhof 033b8ffe3f [ARM] 4599/1: Preserve ATAG list for use with kexec (2.6.23)
This patch resolves a kexec boot failure that can occur because
no ATAGs are passed in to the kexec'd kernel. Currently the
newly-kexec'd kernel may fail if it requires specific ATAGs, or
it may fail because the fixed memory location at which it expects
to find the ATAGs may contain random data instead of ATAGs.

The patch ensures that any ATAGs passed to the current kernel
at boot time are copied to a static buffer, and are copied back
when kexec copies the new kernel into place. Thus the new
kernel sees the same ATAGs from kexec and the boot loader.

The boot parameters are copied without regard to type, content,
or length -- this patch's scope is limited soley to saving and
restoring a fixed-size block of memory containing the kernel's
boot parameters. Additional functionality to examine, alter, or
replace the ATAGs (using kexec, for example) can be implemented
by manipulating the static buffer containing the preserved ATAGs.

Note: the size of the buffer (1.5KB) is selected to comfortably
hold one of each ATAG type, including a maximum-length command
line and the maximum number of ATAG_MEM structures currently
supported by the kernel. Should an ATAG list exceed that limit,
the list will be silently truncated to that limit (to do other-
wise at that point in the boot process would make a simple
problem exceedingly complicated).

[Note: this is the same patch as 4579, modified to accomodate
the ATAG changes introduced in 2.6.23]

Russell King cba774ae87 [ARM] Add rtc-cmos driver for ISA-based footbridge platforms
... but the rtc-cmos is rather broken; if PNP is enabled, it assumes
that we have ACPI (!) which is quite bogus on these platforms -
which may have ISAPNP but not ACPI.  Something to be solved in the
future.

Catalin Marinas 180005c4ef [ARM] 4585/1: Correctly identify the CPU architecture version
The cpu_architecture() function in arch/arm/kernel/setup.c only works
with cores produced by ARM Ltd. The more generic approach is to read
the ID_MMFR0 register and check for the VMSA or PMSA version
supported. With this patch, the ARM11MPCore would be reported as ARMv7
since its MMU is compatible with ARMv7.

David Brownell 5e802dfab7 [ARM] 4539/1: clocksource and clockevents for at91rm9200
GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200.

 - Oneshot mode (used for NO_HZ and high res timers) uses the
   alarm to emulate a real oneshot timer; the trickiest bit is
   how to avoid some lowlevel races.  Thanks to Remy Bohmer for
   various fixes to this code.

 - Tighten up periodic mode support using the PIT.

 - Streamline reads of the 32KHz counter.  Thanks to Marc Pignat
   for some testing results: the CRTR register has *very* odd
   behavior.  The reread appears to work around stranger glitches
   than just getting an old clock value (which would quickly
   self-correct).

 - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100),
   since that no longer acts correct (time increases too fast).

Note that the at91sam9 and at91x40 chips need other solutions,
since they don't have the same system timer module.
