Commit "ARM: gic: add irq_domain support" (b49b6ff) breaks SPARSE_IRQ
on platforms with GIC. When SPARSE_IRQ is enabled, all NR_IRQS or
mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused
irq_alloc_descs to allocate irq_descs after the pre-allocated space.
Make irq_alloc_descs search for an exact irq range and assume it has
been pre-allocated on failure. For DT probing dynamic allocation is used.
DT enabled platforms should set their nr_irqs to NR_IRQ_LEGACY and have all
irq_chips allocate their irq_descs with irq_alloc_descs if SPARSE_IRQ is
enabled.
gic_init irq_start param is changed to be signed with negative meaning do
dynamic Linux irq assigment.

This adds ARM gic interrupt controller initialization using device tree
data.
The initialization function is intended to be called by of_irq_init
function like this:
const static struct of_device_id irq_match[] = {
{ .compatible = "arm,cortex-a9-gic", .data = gic_of_init, },
{}
};
static void __init init_irqs(void)
{
of_irq_init(irq_match);
}

Convert the gic interrupt controller to use irq domains in preparation
for device-tree binding and MULTI_IRQ. This allows for translation between
GIC interrupt IDs and Linux irq numbers.
The meaning of irq_offset has changed. It now is just the number of skipped
GIC interrupt IDs for the controller. It will be 16 for primary GIC and 32
for secondary GICs.

A lot of files pull in module.h when all they are really
looking for is the basic EXPORT_SYMBOL functionality. The
recent data from Ingo[1] shows that this is one of several
instances that has a significant impact on compile times,
and it should be targeted for factoring out (as done here).
Note that several commonly used header files in include/*
directly include <linux/module.h> themselves (some 34 of them!)
The most commonly used ones of these will have to be made
independent of module.h before the full benefit of this change
can be realized.
We also transition THIS_MODULE from module.h to export.h,
since there are lots of files with subsystem structs that
in turn will have a struct module *owner and only be doing:
.owner = THIS_MODULE;
and absolutely nothing else modular. So, we also want to have
the THIS_MODULE definition present in the lightweight header.

Interrupt controllers can have non-zero starting value for h/w irq numbers.
Adding support in irq_domain allows the domain hwirq numbering to match
the interrupt controllers' numbering.
As this makes looping over irqs for a domain more complicated, add loop
iterators to iterate over all hwirqs and irqs for a domain.

SDCC runtime suspend can race with mmc_rescan causing deadlock.
The call flow would be this:
1) When runtime suspend is triggered:
msmsdcc_runtime_suspend()
-> mmc_suspend_host()
-> mmc_flush_scheduled_work()
2) mmc_flush_schedule_work() waits for mmc_rescan() work
to be completed if it is already in runqueue.
3) When mmc_rescan() is scheduled to run:
mmc_claim_host()
-> msmsdcc_enable()
->pm_runtime_get_sync()
4) pm_runtime_get_sync() waits for runtime_suspend to complete,
and hence cause two threads to wait upon each other.
Fix this deadlock by aborting runtime suspend when mmc_rescan
is scheduled.

ARM: gic: consolidate PPI handling
PPI handling is a bit of an odd beast. It uses its own low level
handling code and is hardwired to the local timers (hence lacking
a registration interface).
Instead, switch the low handling to the normal SPI handling code.
PPIs are handled by the handle_percpu_devid_irq flow.
This also allows the removal of some duplicated code.

ARM: gic, local timers: use the request_percpu_irq() interface
This patch remove the hardcoded link between local timers and PPIs,
and convert the PPI users (TWD, MCT and MSM timers) to the new
*_percpu_irq interface. Also some collateral cleanup
(local_timer_ack() is gone, and the interrupt handler is strictly
private to each driver).
PPIs are now useable for more than just the local timers.
Additional testing by David Brown (msm8250 and msm8660) and
Shawn Guo (imx6q).

* changes:
hsic: Put data/strobe into reset when peripheral disconnects
mdm2: Disconnect and connect hsic when mdm status goes high
mdm2: Replace hsic platform_add/remove with connect/disconnect
This removes need from drivers to parse the beacon tail/head data
to figure out what crypto settings are to be used in AP mode in case
the Beacon and Probe Response frames are fully constructed in the
driver/firmware.
nl80211/cfg80211: Allow SSID to be specified in new beacon command
This makes it easier for drivers that generate Beacon and Probe Response
frames internally (in firmware most likely) in AP mode.
nl80211/cfg80211: Add extra IE configuration to AP mode setup
The NL80211_CMD_NEW_BEACON command is, in practice, requesting AP mode
operations to be started. Add new attributes to provide extra IEs
(e.g., WPS IE, P2P IE) for drivers that build Beacon, Probe Response,
and (Re)Association Response frames internally (likely in firmware).
