GCC explicitly does not warn for unused static inline functions for -Wunused-function. The manual states: Warn whenever a static function is declared but not defined or a non-inline static function is unused. Clang does warn for static inline functions that are unused. It turns out that suppressing the warnings avoids potentially complex #ifdef directives, which also reduces LOC. Suppress the warning for clang.

the reason is that the managed memory is too low (only 110MB) while the
rest of the the 50GB is still waiting for the deferred intialization to
be done. update_defer_init estimates the initial memoty to initialize
to 2GB at least but it doesn't consider any memory allocated in that
range. In this particular case we've had
Reserving 4096MB of memory at 128MB for crashkernel (System RAM: 51200MB)
so the low 2GB is mostly depleted.
Fix this by considering memblock allocations in the initial static
initialization estimation. Move the max_initialise to
reset_deferred_meminit and implement a simple memblock_reserved_memory
helper which iterates all reserved blocks and sums the size of all that
start below the given address. The cumulative size is than added on top
of the initial estimation. This is still not ideal because
reset_deferred_meminit doesn't consider holes and so reservation might
be above the initial estimation whihch we ignore but let's make the
logic simpler until we really need to handle more complicated cases.

KVM uses get_user_pages() to resolve its stage2 faults. KVM sets the FOLL_HWPOISON flag causing faultin_page() to return -EHWPOISON when it finds a VM_FAULT_HWPOISON. KVM handles these hwpoison pages as a special case. (check_user_page_hwpoison()) When huge pages are involved, this doesn't work so well. get_user_pages() calls follow_hugetlb_page(), which stops early if it receives VM_FAULT_HWPOISON from hugetlb_fault(), eventually returning -EFAULT to the caller. The step to map this to -EHWPOISON based on the FOLL_ flags is missing. The hwpoison special case is skipped, and -EFAULT is returned to user-space, causing Qemu or kvmtool to exit. Instead, move this VM_FAULT_ to errno mapping code into a header file and use it from faultin_page() and follow_hugetlb_page(). With this, KVM works as expected. This isn't a problem for arm64 today as we haven't enabled MEMORY_FAILURE, but I can't see any reason this doesn't happen on x86 too, so I think this should be a fix. This doesn't apply earlier than stable's v4.11.1 due to all sorts of cleanup. [james.morse@arm.com: add vm_fault_to_errno() call to faultin_page()] suggested.

This patch adds various verifier test cases: 1) A test case for the pruning issue when tracking alignment is used. 2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer arithmetic turns such register into UNKNOWN_VALUE type. 3) Test cases for the special treatment of LD_ABS/LD_IND to make sure verifier doesn't break calling convention here. Latter is needed, since f.e. arm64 JIT uses r1 - r5 for storing temporary data, so they really must be marked as NOT_INIT.

In most cases, a cgroup controller don't care about the liftimes of cgroups. For the controller, a css becomes online when ->css_online() is called on it and offline when ->css_offline() is called. However, cpuset is special in that the user interface it exposes cares whether certain cgroups exist or not. Combined with the RCU delay between cgroup removal and css offlining, this can lead to user visible behavior oddities where operations which should succeed after cgroup removals fail for some time period. The effects of cgroup removals are delayed when seen from userland. This patch adds css_is_dying() which tests whether offline is pending and updates is_cpuset_online() so that the function returns false also while offline is pending. This gets rid of the userland visible delays.

Currently when firmware command gets stuck or it takes long time to
complete, the driver command will get timeout and the command slot is
freed and can be used for new commands, and if the firmware receive new
command on the old busy slot its behavior is unexpected and this could
be harmful.
To fix this when the driver command gets timeout we return failure,
but we don't free the command slot and we wait for the firmware to
explicitly respond to that command.
Once all the entries are busy we will stop processing new firmware
commands.

When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default. This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.
Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.
Fix this by properly initializing ptracer_cred in ptrace_init_task
This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork. Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

====================
Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:
1) When using IPVS in direct-routing mode, normal traffic from the LVS
host to a back-end server is sometimes incorrectly NATed on the way
back into the LVS host. Patch to fix this from Julian Anastasov.
2) Calm down clang compilation warning in ctnetlink due to type
mismatch, from Matthias Kaehlcke.
3) Do not re-setup NAT for conntracks that are already confirmed, this
is fixing a problem that was introduced in the previous nf-next batch.
Patch from Liping Zhang.
4) Do not allow conntrack helper removal from userspace cthelper
infrastructure if already in used. This comes with an initial patch
to introduce nf_conntrack_helper_put() that is required by this fix.
From Liping Zhang.
5) Zero the pad when copying data to userspace, otherwise iptables fails
to remove rules. This is a follow up on the patchset that sorts out
the internal match/target structure pointer leak to userspace. Patch
from the same author, Willem de Bruijn. This also comes with a build
failure when CONFIG_COMPAT is not on, coming in the last patch of
this series.
6) SYNPROXY crashes with conntrack entries that are created via
ctnetlink, more specifically via conntrackd state sync. Patch from
Eric Leblond.
7) RCU safe iteration on set element dumping in nf_tables, from
Liping Zhang.
8) Missing sanitization of immediate date for the bitwise and cmp
expressions in nf_tables.
9) Refcounting logic for chain and objects from set elements does not
integrate into the nf_tables 2-phase commit protocol.
10) Missing sanitization of target verdict in ebtables arpreply target,
from Gao Feng.

Pull libnvdimm fixes from Dan Williams: "A couple of compile fixes. With the removal of the ->direct_access() method from block_device_operations in favor of a new dax_device + dax_operations we broke two configurations. The CONFIG_BLOCK=n case is fixed by compiling out the block+dax helpers in the dax core. Configurations with FS_DAX=n EXT4=y / XFS=y and DAX=m fail due to the helpers the builtin filesystem needs being in a module, so we stub out the helpers in the FS_DAX=n case." * 'libnvdimm-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: dax, xfs, ext4: compile out iomap-dax paths in the FS_DAX=n case dax: fix false CONFIG_BLOCK dependency

We had a small batch of fixes before -rc1, but here is a larger one. It
contains a backmerge of 4.12-rc1 since some of the downstream branches we
merge had that as base; at the same time we already had merged contents
before -rc1 and rebase wasn't the right solution.
A mix of random smaller fixes and a few things worth pointing out:
- We've started telling people to avoid cross-tree shared branches if all
they're doing is picking up one or two DT-used constants from a
shared include file, and instead to use the numeric values on first
submission. Follow-up moving over to symbolic names are sent in right
after -rc1, i.e. here. It's only a few minor patches of this type.
- Linus Walleij and others are resurrecting the 'Gemini' platform, and
wanted a cut-down platform-specific defconfig for it. So I picked that
up for them.
- Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps
people to prepare patches since it's a pain when defconfig and current
savedefconfig contents differs too much.
- Devicetree additions for some pinctrl drivers for Armada that were
merged this window. I'd have preferred to see those earlier but it's not
a huge deail.
The biggest change worth pointing out though since it's touching other
parts of the tree: We added prefixes to be used when cross-including
DT contents between arm64 and arm, allowing someone to #include
<arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
resulted in a recursive symlink.
Instead, I've now moved it out of arch/*/boot/dts/include, into a shared
location under scripts/dtc. While I was at it, I consolidated so all
architectures now behave the same way in this manner.
Rob Herring (DT maintainer) has acked it. I cc:d most other arch
maintainers but nobody seems to care much; it doesn't really affect them
since functionality is unchanged for them by default.

Add a new interface for registering a serdev controller and clients, and a helper function to deregister serdev devices (or a tty device) that were previously registered using the new interface. Once every driver currently using the tty_port_register_device() helpers have been vetted and converted to use the new serdev registration interface (at least for deregistration), we can move serdev registration to the current helpers and get rid of the serdev-specific functions.

According to xHCI spec Figure 30: Interrupt Throttle Flow Diagram
If PCI Message Signaled Interrupts (MSI or MSI-X) are enabled,
then the assertion of the Interrupt Pending (IP) flag in Figure 30
generates a PCI Dword write. The IP flag is automatically cleared
by the completion of the PCI write.
the MSI enabled HCs don't need to clear interrupt pending bit, but
hcd->irq = 0 doesn't equal to MSI enabled HCD. At some Dual-role
controller software designs, it sets hcd->irq as 0 to avoid HCD
requesting interrupt, and they want to decide when to call usb_hcd_irq
by software.

Enabling the tracer selftest triggers occasionally the warning in
text_poke(), which warns when the to be modified page is not marked
reserved.
The reason is that the tracer selftest installs kprobes on functions marked
__init for testing. These probes are removed after the tests, but that
removal schedules the delayed kprobes_optimizer work, which will do the
actual text poke. If the work is executed after the init text is freed,
then the warning triggers. The bug can be reproduced reliably when the work
delay is increased.
Flush the optimizer work and wait for the optimizing/unoptimizing lists to
become empty before returning from the kprobes tracer selftest. That
ensures that all operations which were queued due to the probes removal
have completed.
