Move all the EDAC core functionality behind CONFIG_EDAC and get rid of
that indirection. Update defconfigs which had it.
While at it, fix dependencies such that EDAC depends on RAS for the
tracepoints.

Apparently, some machines used to report DRAM errors through a PCI SERR
NMI. This is why we have a call into EDAC in the NMI handler. See
c0d121720220 ("drivers/edac: add new nmi rescan").
From looking at the patch above, that's two drivers: e752x_edac.c and
e7xxx_edac.c. Now, I wanna say those are old machines which are probably
decommissioned already.
Tony says that "[t]the newest CPU supported by either of those drivers
is the Xeon E7520 (a.k.a. "Nehalem") released in Q1'2010. Possibly some
folks are still using these ... but people that hold onto h/w for 7
years generally cling to old s/w too ... so I'd guess it unlikely that
we will get complaints for breaking these in upstream."
So even if there is a small number still in use, we did load EDAC with
edac_op_state == EDAC_OPSTATE_POLL by default (we still do, in fact)
which means a default EDAC setup without any parameters supplied on the
command line or otherwise would never even log the error in the NMI
handler because we're polling by default:
inline int edac_handler_set(void)
{
if (edac_op_state == EDAC_OPSTATE_POLL)
return 0;
return atomic_read(&edac_handlers);
}
So, long story short, I'd like to get rid of that nastiness called
edac_stub.c and confine all the EDAC drivers solely to drivers/edac/. If
we ever have to do stuff like that again, it should be notifiers we're
using and not some insanity like this one.

Currently, the arch timer driver uses ARCH_TIMER_PHYS_SECURE_PPI to mean
the driver will use the secure PPI *and* potentially also use the
non-secure PPI. This is somewhat confusing.
For arm64 it never makes sense to use the secure PPI, but we do anyway,
inheriting this behaviour from 32-bit arm. For ACPI, we may not even
have a valid secure PPI, so we need to be able to only request the
non-secure PPI.
To that end, this patch reworks the timer driver so that we can request
the non-secure PPI alone. The PPI selection is split out into a new
function, arch_timer_select_ppi(), and verification of the selected PPI
is shifted out to callers (as DT may select the PPI by other means and
must handle this anyway).
We now consistently use arch_timer_has_nonsecure_ppi() to determine
whether we must manage a non-secure PPI *in addition* to a secure PPI.
When we only have a non-secure PPI, this returns false.

Almost all string in the arm_arch_timer driver duplicate an common
prefix (though a few do not). For consistency, it would be better to use
pr_fmt(), and always use this prefix. At the same time, we may as well
clean up some whitespace issues in arch_timer_banner and
arch_timer_init.

calculate_min_delta() may incorrectly access a 4th element of buf2[]

been reported to cause strange crashes in start_kernel() sometime after

This patch hard-codes CRYPTO_MAX_NAME in the user-space API to
64, which is the current value of CRYPTO_MAX_ALG_NAME. This patch
also replaces all remaining occurences of CRYPTO_MAX_ALG_NAME
in the user-space API with CRYPTO_MAX_NAME.
This way the user-space API will not be modified when we raise
the value of CRYPTO_MAX_ALG_NAME.
Furthermore, the code has been updated to handle names longer than
the user-space API. They will be truncated.

Some hardware RNGs provide a single register for obtaining random data.
Instead of signaling when new data is available, the reader must wait a
fixed amount of time between reads for new data to be generated.
timeriomem_rng implements this scheme with the period specified in
platform data or device tree. While the period is specified in
microseconds, the implementation used a standard timer which has a
minimum delay of 1 jiffie and caused a significant bottleneck for
devices that can update at 1us. By switching to an hrtimer, 1us periods
now only delay at most 2us per read.

The algif_aead completion function tries to deduce the aead_request
from the crypto_async_request argument. This is broken because
the API does not guarantee that the same request will be pased to
the completion function. Only the value of req->data can be used
in the completion function.
This patch fixes it by storing a pointer to sk in areq and using
that instead of passing in sk through req->data.

The ahash API modifies the request's callback function in order
to clean up after itself in some corner cases (unaligned final
and missing finup).
When the request is complete ahash will restore the original
callback and everything is fine. However, when the request gets
an EBUSY on a full queue, an EINPROGRESS callback is made while
the request is still ongoing.
In this case the ahash API will incorrectly call its own callback.
This patch fixes the problem by creating a temporary request
object on the stack which is used to relay EINPROGRESS back to
the original completion function.
This patch also adds code to preserve the original flags value.

mipsxx_pmu_handle_shared_irq() calls irq_work_run() while holding the
pmuint_rwlock for read. irq_work_run() can, via perf_pending_event(),
call try_to_wake_up() which can try to take rq->lock.
However, perf can also call perf_pmu_enable() (and thus take the
pmuint_rwlock for write) while holding the rq->lock, from
finish_task_switch() via perf_event_context_sched_in().
This leads to an ABBA deadlock:

Since commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts"),
the gic driver has been allocating virq's for local interrupts during
its initialisation. Unfortunately on Malta platforms, these are the
first IRQs to be allocated and so are allocated virqs 1-3. The i8259
driver uses a legacy irq domain which expects to map virqs 0-15. Probing
of that driver therefore fails because some of those virqs are already
taken, with the warning:

git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel
Samsung pinctrl drivers update for v4.12:
1. Add support for pad retention control through pinctrl drivers which
moves us forward to better runtime PM of pinctrl, clocks, power domains
and other devices.
2. Fix GPIO hogs by registering pinctrl before registering gpiolib.
3. Use devm-like interface.

The commit 1259feddd0f8("pinctrl: samsung: Fix the width of
PINCFG_TYPE_DRV bitfields for Exynos5433") already fixed
the different width of PINCFG_TYPE_DRV from previous Exynos SoC.
However wrong merge conflict resolution was chosen in commit
7f36f5d11cda ("Merge tag 'v4.10-rc6' into devel") effectively dropping
the changes for PINCFG_TYPE_DRV. Re-do them here.
The macro EXYNOS_PIN_BANK_EINTW is no longer used so remove it.

In the (very unlikely) case a passive socket becomes a listener,
we do not want to duplicate its saved SYN headers.
This would lead to double frees, use after free, and please hackers and
various fuzzers
Tested:
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, IPPROTO_TCP, TCP_SAVE_SYN, [1], 4) = 0
+0 fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
+0 bind(3, ..., ...) = 0
+0 listen(3, 5) = 0
+0 < S 0:0(0) win 32972 <mss 1460,nop,wscale 7>
+0 > S. 0:0(0) ack 1 <...>
+.1 < . 1:1(0) ack 1 win 257
+0 accept(3, ..., ...) = 4
+0 connect(4, AF_UNSPEC, ...) = 0
+0 close(3) = 0
+0 bind(4, ..., ...) = 0
+0 listen(4, 5) = 0
+0 < S 0:0(0) win 32972 <mss 1460,nop,wscale 7>
+0 > S. 0:0(0) ack 1 <...>
+.1 < . 1:1(0) ack 1 win 257

This reverts commit def12888c161e6fec0702e5ec9c3962846e3a21d.
As per discussion between Roopa Prabhu and David Ahern, it is
advisable that we instead have the code collect the setlink triggered
events into a bitmask emitted in the IFLA_EVENT netlink attribute.

====================
40GbE Intel Wired LAN Driver Updates 2017-04-08
This series contains updates to i40e and i40evf only.
Mitch fixes an issue where the client driver (i40iw) was attempting to
load on x710 devices (which do not support iWARP), so only register with
the client if iWARP is supported.
Jake fixes up error messages to better clarify to the user when adding a
invalid flow type. Updates the driver to look up the MAC address from
eth_get_platform_mac_address() first before checking what the firmware
provides. Cleans up code so we are not repeating a duplicate loop, by
checking both transmit and receive queues in a single loop. Also cleans
up flags never used, so remove the definitions.
Alex does cleanup so that we are always updating pf->flags when a change
is made to the private flags. Adds support for 3K buffers to the receive
path so that we can provide the additional padding needed in the event
of NET_IP_ALIGN being non-zero or a cache line being greater than 64.
Adds support for build_skb() to i40e/i40evf.
Maciej adjusts the scope of the rtnl lock held during reset because it
was stopping other PFs from running their reset procedures.
Alan reduces code complexity in i40e_detect_recover_hung_queue().

both our sqsize and the controller MQES cap are a 0 based value,
