Commit bfc8c90139 ("mem-hotplug: implement get/put_online_mems")
introduced new functions get/put_online_mems() and mem_hotplug_begin/end()
in order to allow similar semantics for memory hotplug like for cpu
hotplug.
The corresponding functions for cpu hotplug are get/put_online_cpus()
and cpu_hotplug_begin/done() for cpu hotplug.
The commit however missed to introduce functions that would serialize
memory hotplug operations like they are done for cpu hotplug with
cpu_maps_update_begin/done().
This basically leaves mem_hotplug.active_writer unprotected and allows
concurrent writers to modify it, which may lead to problems as outlined
by commit f931ab479d ("mm: fix devm_memremap_pages crash, use
mem_hotplug_{begin, done}").
That commit was extended again with commit b5d24fda9c ("mm,
devm_memremap_pages: hold device_hotplug lock over mem_hotplug_{begin,
done}") which serializes memory hotplug operations for some call sites
by using the device_hotplug lock.
In addition with commit 3fc2192410 ("mm: validate device_hotplug is held
for memory hotplug") a sanity check was added to mem_hotplug_begin() to
verify that the device_hotplug lock is held.
This in turn triggers the following warning on s390:
WARNING: CPU: 6 PID: 1 at drivers/base/core.c:643 assert_held_device_hotplug+0x4a/0x58
Call Trace:
assert_held_device_hotplug+0x40/0x58)

kernel_init_freeable+0x228/0x2d8
kernel_init+0x2a/0x140
kernel_thread_starter+0x6/0xc
One possible fix would be to add more lock_device_hotplug() and
unlock_device_hotplug() calls around each call site of
mem_hotplug_begin/end(). But that would give the device_hotplug lock
additional semantics it better should not have (serialize memory hotplug
operations).
Instead add a new memory_add_remove_lock which has the similar semantics
like cpu_add_remove_lock for cpu hotplug.
To keep things hopefully a bit easier the lock will be locked and unlocked
within the mem_hotplug_begin/end() functions.

When vmalloc() fails it prints a very lengthy message with all the
details about memory consumption assuming that it happened due to OOM.
However, vmalloc() can also fail due to fatal signal pending. In such
case the message is quite confusing because it suggests that it is OOM
but the numbers suggest otherwise. The messages can also pollute
console considerably.
Don't warn when vmalloc() fails due to fatal signal pending.

We still get a build error in random configurations, after this has been
modified a few times:
In file included from include/linux/mm.h:68:0,

arch/x86/include/asm/pgtable.h:66:26: error: redefinition of 'native_pud_clear'
#define pud_clear(pud) native_pud_clear(pud)
My interpretation is that the build error comes from a typo in
__PAGETABLE_PUD_FOLDED, so fix that typo now, and remove the incorrect
#ifdef around the native_pud_clear definition.

Add a prototype of task_struct to fix below warning on arm64.

As same as other types (kmem_cache, page, and vm_struct) this adds a
prototype of task_struct data structure on top of kasan.h.

different line in the same file in v4.11-rc2. The patch from Masami

====================
qed: Fixes series
This address several different issues in qed.
The more significant portions:
Patch #1 would cause timeout when qedr utilizes the highest
CIDs availble for it [or when future qede adapters would utilize
queues in some constellations].
Patch #4 fixes a leak of mapped addresses; When iommu is enabled,
offloaded storage protocols might eventually run out of resources
and fail to map additional buffers.
Patches #6,#7 were missing in the initial iSCSI infrastructure
submissions, and would hamper qedi's stability when it reaches
out-of-order scenarios.

Before iterating over the the LL2 Rx ring, the ring's
spinlock is taken via spin_lock_irqsave().
The actual processing of the packet [including handling
by the protocol driver] is done without said lock,
so qed releases the spinlock and re-claims it afterwards.
Problem is that the final spin_lock_irqrestore() at the end
of the iteration uses the original flags saved from the
initial irqsave() instead of the flags from the most recent
irqsave(). So it's possible that the interrupt status would
be incorrect at the end of the processing.

Touching HW while clocks are off is a serious error and for instance
breaks suspend functionality. After this patch tilcdc_crtc_update_fb()
always updates the primary plane's framebuffer pointer, increases fb's
reference count and stores vblank event. tilcdc_crtc_update_fb() only
writes the fb's DMA address to HW if the crtc is enabled, as
tilcdc_crtc_enable() takes care of writing the address on enable.
This patch also refactors the tilcdc_crtc_update_fb() a bit. Number of
subsequent small changes had made it almost unreadable. There should
be no other functional changes but checking the CRTC's enable
state. However, the locking goes a bit differently and some of the
redundant checks have been removed in this new version.
The enable_lock should be enough to protect the access to
tilcdc_crtc->enabled. The irq_lock protects the access to last_vblank
and next_fb. The check for vrefresh and last_vblank being valid is
redundant, as the vrefresh should be always valid if the CRTC is
enabled and now last_vblank should be too, because it is initialized
to current time when CRTC raster is enabled. If for some reason the
values are not correctly initialized the division by zero warning is
quite appropriate.
