DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src()
tries to use __raw_{read,write}l() to read from and write to physical
addresses, but those functions take virtual addresses.
sparse caught this:
arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident>

arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/timer.c:52:9: got unsigned int
Fix by using omap_{read,writel}(), just like the other users of the
MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term,
removing omap_{read,write}l() is the appropriate thing to do; but
this will take some work to do this cleanly.
Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion
to platform devices) that dangerously moved code and changed it in
the same patch.

The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.
This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.

Commit (7496ba3 ARM: OMAP2+: UART: Add default mux for all uarts)
wrongly added muxing of default pads for all uarts. This causes
breakage on multiple boards using uart pins for alternate functions.
For example, on zoom3 random oopses can be seen with nfsroot as
the smsc911x ethernet FIFO timings on GPMC bus are controlled
by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these
pads to uart4 functionality as commit 7496ba3 was doing.
Not all boards tend to use all uarts and most of unused uart pins
are muxed for other purpose. This commit breaks the modules which
where trying to use unused uart pins on their boards.
So remove the default pad muxing. Note that this is not a complete
fix, as we now rely on bootloader set muxing for the uart wake-up
events. Further patching is needed to enable wake-up events for
uarts that are already muxed to uart mode.

The 'max' range needs to be unsigned, since the size of the user address
space is bigger than 2GB.
We know that 'count' is positive in 'long' (that is checked in the
caller), so we will truncate 'max' down to something that fits in a
signed long, but before we actually do that, that comparison needs to be
done in unsigned.
Bug introduced in commit 92ae03f2ef99 ("x86: merge 32/64-bit versions of
'strncpy_from_user()' and speed it up"). On x86-64 you can't trigger
this, since the user address space is much smaller than 63 bits, and on
x86-32 it works in practice, since you would seldom hit the strncpy
limits anyway.
I had actually tested the corner-cases, I had only tested them on
x86-64. Besides, I had only worried about the case of a pointer *close*
to the end of the address space, rather than really far away from it ;)
This also changes the "we hit the user-specified maximum" to return
'res', for the trivial reason that gcc seems to generate better code
that way. 'res' and 'count' are the same in that case, so it really
doesn't matter which one we return.

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.
This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

During booting of cpu1, there is a short window where cpu1
is online, but not active where cpu1 is occupied by waiting
to become active. If cpu0 then decides to schedule something
on cpu1 and wait for it to complete, before cpu0 has set
cpu1 active, we have a deadlock.
Typically it's this CPU frequency transition that happens at
this time, so let's just not wait for it to happen, it will
happen whenever the CPU eventually comes online instead.

Commit 26f41062f28d ("PCI: check for pci bar restore completion and
retry") attempted to address problems with PCI BAR restoration on
systems where FLR had not been completed before pci_restore_state() was
called, but it did that in an utterly wrong way.
First off, instead of retrying the writes for the BAR registers only, it
did that for all of the PCI config space of the device, including the
status register (whose value after the write quite obviously need not be
the same as the written one). Second, it added arbitrary delay to
pci_restore_state() even for systems where the PCI config space
restoration was successful at first attempt. Finally, the mdelay(10) it
added to every iteration of the writing loop was way too much of a delay
for any reasonable device.
All of this actually caused resume failures for some devices on Mikko's
system.
To fix the regression, make pci_restore_state() only retry the writes
for BAR registers and only wait if the first read from the register
doesn't return the written value. Additionaly, make it wait for 1 ms,
instead of 10 ms, after every failing attempt to write into config
space.

Commit 18a4d0a22ed6 ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.
Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.

Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no
longer need/use the clock framework code for filling up CPUfreq
tables. Remove it.
Removing this code also eliminates build errors when CPU_FREQ_TABLE
support is not enabled.
Thanks to Russell King for pointing out the parts I missed under
plat-omap in the original version and also pointing out the build
errors when CPUFREQ_TABLE support was not enabled.

These were incorrectly introduced and can cause problems for of_irq_init.
The correct way to define a root controller is no interrupt-parent set at
all or the interrupt-parent is set to the root controller itself when
inherited from a parent node.

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it. Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).
So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.

Pull system.h fixups for less common arch's from Paul Gortmaker:
"Here is what is hopefully the last of the system.h related fixups.
The fixes for Alpha and ia64 are code relocations consistent with what
was done for the more mainstream architectures. Note that the
diffstat lines removed vs lines added are not the same since I've
fixed some of the whitespace issues in the relocated code blocks.
However they are functionally the same. Compile tested locally, plus
these two have been in linux-next for a while.
There is also a trivial one line system.h related fix for the Tilera
arch from Chris Metcalf to fix an implict include.."
