ASoC: cs4271: fix property check

The driver had the property check for 'cirrus,amutec_eq_bmutec' the
wrong way around. That happens if you misspell the property in the
bindings during tests.

usb: dwc3: debugfs: fix regdump offset

As with dwc_readl/writel, the global registers are specified as
offsets starting from the beginning of the xHCI address space,
but the memory region pointed to by dwc->regs already maps to
the start of the global addresses. Fix by offsetting each of the
regs relative to DWC3_GLOBALS_REGS_START.

usb: gadget: dummy: fix enumeration with g_multi

If we do have endpoints named like "ep-a" then bEndpointAddress is
counted internally by the gadget framework.

If we do have endpoints named like "ep-1" then bEndpointAddress is
assigned from the digit after "ep-".

If we do have both, then it is likely that after we used up the
"generic" endpoints we will use the digits and thus assign one
bEndpointAddress to multiple endpoints.

This theory can be proofed by using the completely enabled g_multi.
Without this patch, the mass storage won't enumerate and times out
because it shares endpoints with RNDIS.

This patch also adds fills up the endpoints list so we have in total
endpoints 1 to 15 in + out available while some of them are restricted
to certain types like BULK or ISO. Without this change the nokia gadget
won't load because the system does not provide enough (BULK) endpoints
but it did before ep-a - ep-f were removed.

usb: musb: dsps: header movement build error fix

"54db6ee ARM: OMAP2+: Introduce local usb.h" moved control module bit
definitions from plat/usb.h (which dsps glue was using) to a local
header in mach-omap2. And in parallel,
"c68bb4c usb: musb: dsps: control module handling (quirk)" added
control module handling capability to dsps glue driver that used
those control module bit definitions.

Integration of above two changes would cause build error in musb dsps
glue driver (they go through different trees upstream) as is seen now
in linux-next. Fix it by adding necessary definitions in dsps glue
driver.

Add rcu user eqs exception hooks for async page fault

This patch adds user eqs exception hooks for async page fault page not
present code path, to exit the user eqs and re-enter it as necessary.

Async page fault is different from other exceptions that it may be
triggered from idle process, so we still need rcu_irq_enter() and
rcu_irq_exit() to exit cpu idle eqs when needed, to protect the code
that needs use rcu.

As Frederic pointed out it would be safest and simplest to protect the
whole kvm_async_pf_task_wait(). Otherwise, "we need to check all the
code there deeply for potential RCU uses and ensure it will never be
extended later to use RCU.".

However, We'd better re-enter the cpu idle eqs if we get the exception
in cpu idle eqs, by calling rcu_irq_exit() before native_safe_halt().

So the patch does what Frederic suggested for rcu_irq_*() API usage
here, except that I moved the rcu_irq_*() pair originally in
do_async_page_fault() into kvm_async_pf_task_wait().

That's because, I think it's better to have rcu_irq_*() pairs to be in
one function ( rcu_irq_exit() after rcu_irq_enter() ), especially here,
kvm_async_pf_task_wait() has other callers, which might cause
rcu_irq_exit() be called without a matching rcu_irq_enter() before it,
which is illegal if the cpu happens to be in rcu idle state.
