Sign-extending TTBR1 addresses when converting to an untagged address
breaks the documented POSIX semantics for mlock() in some obscure error
cases where we end up returning -EINVAL instead of -ENOMEM as a direct
result of rewriting the upper address bits.
Rework the untagged_addr() macro to preserve the upper address bits for
TTBR1 addresses and only clear the tag bits for user addresses. This
matches the behaviour of the 'clear_address_tag' assembly macro, so
rename that and align the implementations at the same time so that they
use the same instruction sequences for the tag manipulation.

When detecting a spurious EL1 translation fault, we have the CPU retry
the translation using an AT S1E1R instruction, and inspect PAR_EL1 to
determine if the fault was spurious.
When PAR_EL1.F == 0, the AT instruction successfully translated the
address without a fault, which implies the original fault was spurious.
However, in this case we return false and treat the original fault as if
it was not spurious.
Invert the return value so that we treat such a case as spurious.

Preempting from IRQ-return means that the task has its PSTATE saved
on the stack, which will get restored when the task is resumed and does
the actual IRQ return.
However, enabling some CPU features requires modifying the PSTATE. This
means that, if a task was scheduled out during an IRQ-return before all
CPU features are enabled, the task might restore a PSTATE that does not
include the feature enablement changes once scheduled back in.
* Task 1:
PAN == 0 ---| |---------------
| |<- return from IRQ, PSTATE.PAN = 0
| <- IRQ |
+--------+ <- preempt() +--
^
|
reschedule Task 1, PSTATE.PAN == 1
* Init:
--------------------+------------------------
^
|
enable_cpu_features
set PSTATE.PAN on all CPUs
Worse than this, since PSTATE is untouched when task switching is done,
a task missing the new bits in PSTATE might affect another task, if both
do direct calls to schedule() (outside of IRQ/exception contexts).
Fix this by preventing preemption on IRQ-return until features are
enabled on all CPUs.
This way the only PSTATE values that are saved on the stack are from
synchronous exceptions. These are expected to be fatal this early, the
exception is BRK for WARN_ON(), but as this uses do_debug_exception()
which keeps IRQs masked, it shouldn't call schedule().

We're missing initializing the PRM_VOLTCTRL register for voltage
controller. Let's add omap4_vc_init_pmic_signaling() similar to what we
have for omap3 and enable voltage control for retention.
This brings down droid4 power consumption with mainline kernel to somewhere
between 40 and 50mW from about 70 to 80 mW for the whole device when
running idle with LCD and backlight off, WLAN connected, and USB and modem
modules unloaded.
Mostly just rmmod of omap2430, ohci-platform and phy-mapphone-mdm6600 are
needed to idle USB and shut down the modem. And after that measuring idle
power consumption can be done with reading sysfs entry periodically
for /sys/class/power_supply/battery/power_avg. Then rmmod of phy-cpcap-usb
will save few more mW, but will disable the debug UART.
Note that sometimes CM_L4PER_UART1_CLKCTRL at 0x4a009540 does not idle
properly after unloading of phy-mapphone-mdm6600.

We can configure voltage controller for cpcap with the data available in
Motorola Mapphone Android Linux kernel. Let's add it so we can have droid4
behave the same way for voltage controller as other omap4 devices and save
some power when idle.
Note that we're now using high-speed i2c mode, looks like the Motorola
kernel had a typo using 0x200 instead of 200 for the timings which may
caused it to not work properly.
Also note that in the long run, this should just become dts data for a

First I thought to put these into intel_crtc_vblank_on() but

Signal descriptors can represent multi-bit bitfields and so have
explicit "enable" and "disable" states. However many descriptor
instances only describe a single bit, and so the SIG_DESC_SET() macro is
provides an abstraction for the single-bit cases: Its expansion
configures the "enable" state to set the bit and "disable" to clear.
SIG_DESC_CLEAR() was introduced to provide a similar single-bit
abstraction for for descriptors to clear the bit of interest. However
its behaviour was defined as the literal inverse of SIG_DESC_SET() - the
impact is the bit of interest is set in the disable path. This behaviour
isn't intuitive and doesn't align with how we want to use the macro in
practice, so make it clear the bit for both the enable and disable
paths.
