DSA: GPIO to reset switches
These two patches add support for using a GPIO to hard reset a switch
during reset.

Thanks to a clue from Neil Armstrong, i figured out how to convert the

Fixes STAR 9000953410: "perf callgraph profiling causing RCU stalls"
| perf record -g -c 15000 -e cycles /sbin/hackbench
|
| INFO: rcu_preempt self-detected stall on CPU
| 1: (1 GPs behind) idle=609/140000000000002/0 softirq=2914/2915 fqs=603
| Task dump for CPU 1:
in-kernel dwarf unwinder has a fast binary lookup and a fallback linear
search (which iterates thru each of ~11K entries) thus takes 2 orders of
magnitude longer (~3 million cycles vs. 2000). Routines written in hand
assembler lack dwarf info (as we don't support assembler CFI pseudo-ops
yet) fail the unwinder binary lookup, hit linear search, failing
nevertheless in the end.
However the linear search is pointless as binary lookup tables are created
from it in first place. It is impossible to have binary lookup fail while
succeed the linear search. It is pure waste of cycles thus removed by
this patch.
This manifested as RCU stalls / NMI watchdog splat when running
hackbench under perf with callgraph profiling. The triggering condition
was perf counter overflowing in routine lacking dwarf info (like memset)
leading to patheic 3 million cycle unwinder slow path and by the time it
returned new interrupts were already pending (Timer, IPI) and taken
rightaway. The original memset didn't make forward progress, system kept
accruing more interrupts and more unwinder delayes in a vicious feedback
loop, ultimately triggering the NMI diagnostic.

We have varied reports of swizzling corruption on gen4 desktop, and
confirmation that one at least is triggered by uneven memory banks
(L-shaped memory). The implication is that the swizzling varies between
the paired channels and the remainder of memory on the single channel. As
the object then has unpredictable swizzling (it will vary depending on
exact page allocation and may even change during the object's lifetime as
the pages are replaced), we have to report to userspace that the swizzling
is unknown.
However, some existing userspace is buggy when it meets an unknown
swizzling configuration and so we need to tell another white lie and
mark the swizzling as NONE but report it as UNKNOWN through the extended
get-tiling-ioctl. See
commit 5eb3e5a5e1
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Sun Jun 28 09:19:26 2015 +0100
drm/i915: Declare the swizzling unknown for L-shaped configurations
for the previous example where we found that telling the truth to
userspace just ends up in a world of hurt.
Also since we don't truly know what the swizzling is on the pages, we
need to keep them pinned to prevent swapping as the reports also
suggest that some gen4 devices have previously undetected bit17
swizzling.
v2: Combine unknown + quirk patches to prevent userspace ever seeing
unknown swizzling through the normal get-tiling-ioctl. Also use the same
path for the existing uneven bank detection for mobile gen4.

In order to enable advertising with privacy enabled, SMP has to be
registered in order to generate new RPA. During power on, it will be
registered at the very end which is the reason why advertising is not
enabled and it's not possible to enable it anymore due to mismatch
between hci_dev settings and actual controller state.
This fixes this problem by moving SMP registration earlier, just after
controller is powered (which is ok, because LE SMP will be already able
to decide on identity address to be used), but before advertising is
enabled.

The Atmel at91 crypto driver unconditionally selects AT_HDMAC,
which results in a Kconfig warning if that driver is not enabled:
warning: (CRYPTO_DEV_ATMEL_AES) selects AT_HDMAC which has unmet direct dependencies (DMADEVICES && ARCH_AT91)
The crypto driver itself does not actually have a dependency
on a particular dma engine, other than this being the one that
is used in at91.
Removing the 'select' gets rid of the warning, but can cause
the driver to be unusable if the HDMAC is not enabled at the
same time. To work around that, this patch clarifies the runtime
dependency to be 'AT_HDMAC || AT_XDMAC', but adds an alternative
for COMPILE_TEST, which lets the driver get build on all systems.
The ARCH_AT91 dependency is implied by AT_XDMAC || AT_HDMAC now
and no longer needs to be listed separately.

The atmel AES driver assumes that 'int' and 'size_t' are the same

This changes the format strings to use the %z modifier when printing
a size_t, and makes sure that we use the correct size_t type where
needed. In case of sg_dma_len(), the type of the result depends
on CONFIG_NEED_SG_DMA_LENGTH, so we have to use min_t to get it to
work in all configurations.
