When a CPU is taken out of reset, either cold booted or hotplugged in,
some of its PMU registers can contain UNKNOWN values.
This patch adds a hotplug notifier to ARM core perf code so that upon
CPU restart the PMU unit is reset and becomes ready to use again.

xscale2 PMUs indicate overflow not via the PMU control register, but by
a separate overflow FLAG register instead.
This patch fixes the xscale2 PMU code to use this register to detect
to overflow and ensures that we clear any pending overflow when
disabling a counter.

The PMU IRQ handlers in perf assume that if a counter has overflowed
then perf must be responsible. In the paranoid world of crazy hardware,
this could be false, so check that we do have a valid event before
attempting to dereference NULL in the interrupt path.

When disabling a counter on an ARMv7 PMU, we should also clear the
overflow flag in case an overflow occurred whilst stopping the counter.
This prevents a spurious overflow being picked up later and leading to
either false accounting or a NULL dereference.

On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.
Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.
This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

It turns out that test-compiling this file on x86-64 doesn't really
help, because much of it is x86-32-specific. And so I hadn't noticed
the slightly over-eager removal of the 'r' from 'addr' variable despite
thinking I had tested it.

Several users of "find_vma_prev()" were not in fact interested in the
previous vma if there was no primary vma to be found either. And in
those cases, we're much better off just using the regular "find_vma()",
and then "prev" can be looked up by just checking vma->vm_prev.
The find_vma_prev() semantics are fairly subtle (see Mikulas' recent
commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return
prev by reference" means that it generates worse code too.
Thus this "let's avoid using this inconvenient and clearly too subtle
interface when we don't really have to" patch.

It turned out that a performance counter on AMD does not
count at all when the GO or HO bit is set in the control
register and SVM is disabled in EFER.
This patch works around this issue by masking out the HO bit
in the performance counter control register when SVM is not
enabled.
The GO bit is not touched because it is only set when the
user wants to count in guest-mode only. So when SVM is
disabled the counter should not run at all and the
not-counting is the intended behaviour.

Carlos was getting
WARNING: at drivers/pci/pci.c:118 pci_ioremap_bar+0x24/0x52()
when probing his sound card, and sound did not work. After adding
pci=use_crs to the kernel command line, no more trouble.
Ok, we can add a quirk. dmidecode output reveals that this is an MSI
MS-7253, for which we already have a quirk, but the short-sighted
author tied the quirk to a single BIOS version, making it not kick in
on Carlos's machine with BIOS V1.2. If a later BIOS update makes it
no longer necessary to look at the _CRS info it will still be
harmless, so let's stop trying to guess which versions have and don't
have accurate _CRS tables.

Commit b27b072791dc (ARM: 7265/1: restart: S3C24XX: use new restart hook)
introduced the new restart hook also for the S3C244x cpus, but it
was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was
selected. Devices using the S3C2442 like the GTA02 normally don't select
this CPU which leads to compilation errors like:
LD .tmp_vmlinux1
arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference
to `s3c2440_restart'
make: *** [.tmp_vmlinux1] Error 1
Therefore move the s3c2440_restart function to s3c244x.c which is
common to both cpus and also fix the naming to reflect this.

In the spirit of commit 29cf7a30f8a0 ("x86/PCI: use host bridge _CRS
info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by
default on a board that needs it.
This fixes boot failures and oopses introduced in 3e3da00c01d0
("x86/pci: AMD one chain system to use pci read out res"). The quirk
is quite targetted (to a specific board and BIOS version) for two
reasons:
(1) to emphasize that this method of tackling the problem one quirk
at a time is a little insane
(2) to give BIOS vendors an opportunity to use simpler tables and
allow us to return to generic behavior (whatever that happens to
be) with a later BIOS update
In other words, I am not at all happy with having quirks like this.
But it is even worse for the kernel not to work out of the box on
these machines, so...

IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
biggest one. It fixes the calls of the function omap_find_iovm_area() in
the omap-iommu-debug module which expects a 'struct device' parameter
since commit fabdbca instead of an omap_iommu handle. The
omap-iommu-debug code still passed the handle to the function which
caused a crash.
The second patch fixes a NULL pointer dereference in the OMAP code and
the third patch makes sure that the omap-iommu is initialized before the
omap-isp driver, which relies on the iommu. The last patch is only a
workaround until defered probing is implemented.

This patch fixes a HW bug by flushing RX FIFOs of the UARTs on init. It was
ported from NXP's git.lpclinux.com tree.

This patch fixes the initialization of the interrupt controller of the LPC32xx
by correctly setting up SIC1 and SIC2 instead of (wrongly) using the same value
as for the Main Interrupt Controller (MIC).

The GPI_28 IRQ was not registered properly. The registration of
IRQ_LPC32XX_GPI_28 was added and the (wrong) IRQ_LPC32XX_GPI_11 at
LPC32XX_SIC1_IRQ(4) was replaced by IRQ_LPC32XX_GPI_28 (see manual of
LPC32xx / interrupt controller).

The new is_compat_task() define for the !COMPAT case in
include/linux/compat.h conflicts with a similar define in
arch/s390/include/asm/compat.h.
This is the minimal patch which fixes the build issues.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
|

omap3isp depends on omap's iommu and will fail to probe if
initialized before it (which always happen if they are builtin).
Make omap's iommu subsys_initcall as an interim solution until
the probe deferral mechanism is merged.

Commit fa0ce403 ("ARM: 7162/1: errata: tidy up Kconfig options for PL310
errata workarounds") introduced a consistent naming scheme for errata
workarounds, but forgot to update the platforms selecting workarounds
using the old names.
This patch updates ux500 and vexpress to select the appropriate PL310
errata workarounds.
