As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.
Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures. In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

get_signal_to_deliver() already resets the signal handler if SA_ONESHOT is
set in ka->sa.sa_flags, there's no need to do it again in handle_signal().
Furthermore, because we were modifying ka->sa.sa_handler (which is a copy
of sighand->action[]) instead of sighand->action[] the original code had
no effect on signal delivery.

intc_ack_data is flagged as __init when it shouldn't be, causing section
mismatches in non-init paths like intc_set_ack_handle():
WARNING: drivers/built-in.o(.text+0x5d760):
Section mismatch in reference from the function
intc_set_ack_handle() to the function .init.text:intc_ack_data()
The function intc_set_ack_handle()
references the function __init intc_ack_data().
This is often because intc_set_ack_handle lacks a __init
annotation or the annotation of intc_ack_data is wrong.

Polling for card hotplug events is a better option than using SDHI native

Now that userspace is making use of kernel-provided sanitized headers for
working out supported interfaces, we need to be a bit more diligent with
matching the syscall definitions with their actual wiring/support state.
In theory it shouldn't hurt anything since sys_ni_syscall will ultimately
do the right thing, but there's also not much need to lie about legacy
x86 syscalls that we've never supported.
This tightens things up a bit for uClibc at least.

When DMA is enabled, sh-sci transfer begins with
uart_start()
sci_start_tx()
if (cookie_tx < 0) schedule_work()
Then, starts DMA when wq scheduled, -- (A)
process_one_work()
work_fn_rx()
cookie_tx = desc->submit_tx()
And finishes when DMA transfer ends, -- (B)
sci_dma_tx_complete()
async_tx_ack()
cookie_tx = -EINVAL
(possible another schedule_work())
This A to B sequence is not reentrant, since controlling variables
(for example, cookie_tx above) are not queues nor lists. So, they
must be invoked as A B A B..., otherwise results in kernel crash.
To ensure the sequence, sci_start_tx() seems to test if cookie_tx < 0
(represents "not used") to call schedule_work().
But cookie_tx will not be set (to a cookie, also means "used") until
in the middle of work queue scheduled function work_fn_tx().
This gap between the test and set allows the breakage of the sequence
under the very frequently call of uart_start().
Another gap between async_tx_ack() and another schedule_work() results
in the same issue, too.
This patch introduces a new condition "cookie_tx == 0" just to mark
it is "busy" and assign it within spin-locked region to fill the gaps.

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

This new subsystem provides a common way to talk to secondary processors
on an SoC, e.g. a DSP, GPU or service processor, using virtio as the
transport. In the long run, it should replace a few dozen vendor
specific ways to do the same thing, which all never made it into the
upstream kernel. There is a broad agreement that rpmsg is the way to
go here and several vendors have started working on replacing their
own subsystems.
Two branches each add one virtio protocol number. Fortunately the
numbers were agreed upon in advance, so there are only context changes.

These changes are all specific to one board only. We're trying to keep
the number of board files low, but generally board level updates are
ok on platforms that are working on moving towards DT based probing,
which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal of
ams_delta_config and the addition of a lot of other data. The Kconfig
file has two changes in the same line, and in exynos, the power domain
cleanup conflicts with the addition of the image sensor device.
