Maintain a bitmap to keep track of which LEB->PEB mapping
was checked already.
That way we have to read back VID headers only once.
Signed-off-by: Richard Weinberger <richard@nod.at>

Fastmap cannot track the LEB unmap operation, therefore it can
happen that after an interrupted erasure the mapping still looks
good from Fastmap's point of view, while reading from the PEB will
cause an ECC error and confuses the upper layer.
Instead of teaching users of UBI how to deal with that, we read back
the VID header and check for errors. If the PEB is empty or shows ECC
errors we fixup the mapping and schedule the PEB for erasure.

Ben Hutchings pointed out that 29b7a6fa1ec0 ("ubi: fastmap: Don't flush
fastmap work on detach") does not really fix the problem, it just
reduces the risk to hit the race window where fastmap work races against
free()'ing ubi->volumes[].
The correct approach is making sure that no more fastmap work is in
progress before we free ubi data structures.
So we cancel fastmap work right after the ubi background thread is
stopped.
By setting ubi->thread_enabled to zero we make sure that no further work
tries to wake the thread.

regulator: fixed/gpio: Revert GPIO descriptor changes due to platform breakage
Commit 6059577cb28 "regulator: fixed: Convert to use GPIO descriptor
only" broke at least the ams-delta platform since the lookup tables
added to the board files use the function name "enable" while the driver
uses NULL causing the regulator to not acquire and control the enable
GPIOs. Revert that and a couple of other commits that are caught up
with it to fix the issue:
2b6c00c157c5bf80 "ARM: pxa, regulator: fix building ezx e680"
6059577cb28d8b15 "regulator: fixed: Convert to use GPIO descriptor only"

Do not update number of enabled dbuf slices in dev_priv struct until we
actually enable/disable dbuf slice in hw. This is leading to never
updating dbuf slices and resulting in DBuf slice mismatch warning.

Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.
I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:
*alloc(a * b, ...) -> *alloc_array(a, b, ...)
and
*zalloc(a * b, ...) -> *calloc(a, b, ...)
as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.
Summary:
- Introduce arithmetic overflow test helper functions (Rasmus)
- Use overflow helpers in 2-factor allocators (Kees, Rasmus)

Pull IPMI updates from Corey Minyard:
"It's been a busy release for the IPMI driver. Some notable changes:
- A user was running into timeout issues doing maintenance commands
over the IPMB network behind an IPMI controller.
Extend the maintenance mode concept to messages over IPMB and allow
the timeouts to be tuned.
- Lots of cleanup, style fixing, some bugfixes, and such.
- At least one user was having trouble with the way the IPMI driver
would lock the i2c driver module it used.
The IPMI driver was not designed for hotplug. However, hotplug is a
reality now, so the IPMI driver was modified to support hotplug.
- The proc interface code is now completely removed. Long live sysfs!"

In order to enable compile-testing but still keep the correct dependency,
this changes the Kconfig logic so we only allow CONFIG_COMPILE_TEST
building when FB_OMAP is completely disabled, or have use the old

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:
// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);

When the PF frequently switches the CMDQ interrupt, if the CMDQ_SRC is
not cleared before the hardware interrupt is generated, the new interrupt
will not be reported.
This patch optimizes this problem by clearing CMDQ_SRC and RESET_STS
before enabling interrupt and syncing pending IRQ handlers after disabling
interrupt.

Before the firmware updates the crq's tail pointer, if the VF driver
reads the data in the crq, the data may be incomplete at this time,
which will lead to the driver read an unknown message.
This patch fixes it by checking if crq is empty before reading the
message.

This commit:
5fdf8e5ba566 ("libnvdimm: re-enable deep flush for pmem devices via fsync()")
intended to make sure that deep flush was always available even on
platforms which support a power-fail protected CPU cache. An unintended
side effect of this change was that we also lost the ability to skip
flushing CPU caches on those power-fail protected CPU cache.
Fix this by skipping the low level cache flushing in dax_flush() if we have
CPU caches which are power-fail protected. The user can still override this
behavior by manually setting the write_cache state of a namespace. See
libndctl's ndctl_namespace_write_cache_is_enabled(),
ndctl_namespace_enable_write_cache() and
ndctl_namespace_disable_write_cache() functions.

Prior to this commit we would only do a "deep flush" (have nvdimm_flush()
write to each of the flush hints for a region) in response to an
msync/fsync/sync call if the nvdimm_has_cache() returned true at the time
we were setting up the request queue. This happens due to the write cache
value passed in to blk_queue_write_cache(), which then causes the block
layer to send down BIOs with REQ_FUA and REQ_PREFLUSH set. We do have a
"write_cache" sysfs entry for namespaces, i.e.:
/sys/bus/nd/devices/pfn0.1/block/pmem0/dax/write_cache
which can be used to control whether or not the kernel thinks a given
namespace has a write cache, but this didn't modify the deep flush behavior
that we set up when the driver was initialized. Instead, it only modified
whether or not DAX would flush CPU caches via dax_flush() in response to
*sync calls.
Simplify this by making the *sync deep flush always happen, regardless of
the write cache setting of a namespace. The DAX CPU cache flushing will
still be controlled the write_cache setting of the namespace.

In the Broadcom Cygnus SoC, the brcm tag needs to be inserted
in between the mac address and the ether type (should use
'DSA_PROTO_TAG_BRCM') for the packets sent to the internal
b53 switch.
Since the Cygnus was added with the BCM58XX device id and the
BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is
broken, due to the incorrect brcm tag location.
Add a new b53 device id (BCM583XX) for Cygnus family to fix the
issue. Add the new device id to the BCM58XX family as Cygnus
is similar to the BCM58XX in most other functionalities.

The current defconfig is inconsistent as it selects the mailbox and
the clock for the hi6220 and the hi3660 without having their Kconfigs
making sure the dependencies are correct. It ends up when selecting
different versions for the kernel (for example when git bisecting)
those options disappear and they don't get back, leading to unexpected
behaviors. In our case, the cpufreq driver does no longer work because
the clock fails to initialize due to the clock stub and the mailbox
missing.
In order to have the dependencies correctly set when defaulting, let's
do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk
automatically") where we select automatically the driver when the
parent driver is selected. With sensible defaults in place, we can leave
other choices for EXPERT.
