6842d4c2a9 Here is another fixes series for AT91 designed for 3.4-rc.
We experienced some issues while compiling some drivers as modules: Joachim has
 corrected several of them. We may reduce this number of exported values by
 reworking some drivers, in the future.
 Some drivers are also modified here, I would like to keep them in the series
 as the modifications are really related with our recent move to irqdomains or
 simply related with compiler annotations.
 I keep dmaengine Kconfig modification in this "fixes" series. The DMA
 driver will not be available for 9x5 SoC family otherwise.

6aaec67da1 ARM: OMAP1: DMTIMER: fix broken timer clock source selection
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:50:13:    got unsigned int
arch/arm/mach-omap1/timer.c:52:9: warning: incorrect type in argument 1 (different base types)
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.

5ae256dcd9 ARM: OMAP: serial: Fix the ocp smart idlemode handling bug
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.

bce492c04b ARM: OMAP2+: UART: Fix incorrect population of default uart pads
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.

078c04545b ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEE
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.

9f85550347 ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus
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.
