Merge tag 'omap-for-v3.13/board-removal-signed-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

From Tony Lindgren:
Changes needed to drop legacy booting support for some
omap3 boards.

Note that that these are based on a merge of the
following for the dependencies:

- v3.12-rc5 for fixes to pinctrl mask
- omap-for-v3.13/dt-signed to avoid pointless merge conflicts
- omap-for-v3.13/quirk-signed for legacy pdata handling

Device Tree support for IGEP boards in mainline is almost
finished. The only remaining bits are support for the
Marvell SD8686 wifi + BT and TFP410 DVI chips.

Adding support for these should be straightforward so let's
not block OMAP3 moving to Device Tree only boot and remove
the board file for IGEP boards.

We now have pretty decent device tree based support for
zoom platforms. It's not complete, but basics work for
me so adding more features should be quite trivial.

Looks like also 3630 sdp is zoom based, and looking
at it's board file should also be trivial to support
with the device tree based booting.

Patches are welcome if people are still using these.

I've tested the serial, MMC, smsc911x, wl12xx, and off-idle support
with the pinctrl patches, so it probably works better than the
board-*.c files ever did. Also the board-omap3evm.c file is broken
for the DSS, and has been for a while. Patches are welcome to fix
it in this .dts file, let's just drop the board-*.c file for this.

Note that off-idle currently requires doing request_irq() on the
wake-up pin from pinctrl-single IRQ domain until we can handle
that in some Linux generic way.

Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel.  The
problem is, that in print_worker_info() we try to read the workqueue info via
the probe_kernel_read() functions which use pagefault_disable() to avoid
crashes like this:
    probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq));
    probe_kernel_read(&wq, &pwq->wq, sizeof(wq));
    probe_kernel_read(name, wq->name, sizeof(name) - 1);

The problem here is, that the first probe_kernel_read(&pwq) might return zero
in pwq and as such the following probe_kernel_reads() try to access contents of
the page zero which is read protected and generate a kernel segfault.

With this patch we fix the interruption handler to call parisc_terminate()
directly only if pagefault_disable() was not called (in which case
preempt_count()==0).  Otherwise we hand over to the pagefault handler which
will try to look up the faulting address in the fixup tables.
