Merge tag 'v4.6-rc7' into drm-next
Merge this back as we've built up a fair few conflicts, and I have
some newer trees to pull in.
Merge fixes from Andrew Morton:
"14 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
byteswap: try to avoid __builtin_constant_p gcc bug
lib/stackdepot: avoid to return 0 handle
mm: fix kcompactd hang during memory offlining
modpost: fix module autoloading for OF devices with generic compatible property
proc: prevent accessing /proc/<PID>/environ until it's ready
mm/zswap: provide unique zpool name
mm: thp: kvm: fix memory corruption in KVM with THP enabled
MAINTAINERS: fix Rajendra Nayak's address
mm, cma: prevent nr_isolated_* counters from going negative
mm: update min_free_kbytes from khugepaged after core initialization
huge pagecache: mmap_sem is unlocked when truncation splits pmd
rapidio/mport_cdev: fix uapi type definitions
mm: memcontrol: let v2 cgroups follow changes in system swappiness
mm: thp: correct split_huge_pages file permission
This is another attempt to avoid a regression in wwn_to_u64() after that
started using get_unaligned_be64(), which in turn ran into a bug on
gcc-4.9 through 6.1.
The regression got introduced due to the combination of two separate
workarounds (commits e3bde9568d: "include/linux/unaligned: force
inlining of byteswap operations" and ef3fb2422f: "scsi: fc: use
get/put_unaligned64 for wwn access") that each try to sidestep distinct
problems with gcc behavior (code growth and increased stack usage).
Unfortunately after both have been applied, a more serious gcc bug has
been uncovered, leading to incorrect object code that discards part of a
function and causes undefined behavior.
As part of this problem is how __builtin_constant_p gets evaluated on an
argument passed by reference into an inline function, this avoids the
use of __builtin_constant_p() for all architectures that set
CONFIG_ARCH_USE_BUILTIN_BSWAP. Most architectures do not set
ARCH_SUPPORTS_OPTIMIZED_INLINING, which means they probably do not
suffer from the problem in the qla2xxx driver, but they might still run
into it elsewhere.
Both of the original workarounds were only merged in the 4.6 kernel, and
the bug that is fixed by this patch should only appear if both are
there, so we probably don't need to backport the fix. On the other
hand, it works by simplifying the code path and should not have any
negative effects.

My last pull request for asm-generic had just one patch that added two
new system calls to asm/unistd.h, but unfortunately it turned out
to be wrong, pointing arch/tile compat mode at the native handlers
rather than the compat ones.
This was spotted by Yury Norov, who is working on ILP32 mode
for arch/arm64, which would have the same problem when merged.
This fixes the table to use the correct compat syscalls, like
the other 64-bit architectures do.
I'll try to find the time to come up with a solution that
prevents this problem from happening again, by allowing all
future system calls to just get added in a single file
for use by all architectures.

Compat architectures that does not use generic unistd (mips, s390),
declare compat version in their syscall tables for preadv2 and
pwritev2. Generic unistd syscall table should do it as well.
[arnd: this initially slipped through the review and an
incorrect patch got merged. arch/tile/ is the only architecture
that could be affected for their 32-bit compat mode, every
other architecture we support today is fine.]

The VIRTIO 1.0 specification added the DEVICE_NEEDS_RESET device status
bit in "VIRTIO-98: Add DEVICE_NEEDS_RESET". This patch defines the
device status bit in the uapi header file so that both the kernel and
userspace applications can use it.
The bit is currently unused by the virtio guest drivers and vhost.
According to the spec "a good implementation will try to recover by
issuing a reset". This is not attempted here because it requires
auditing the virtio drivers to ensure there are no resource leaks or
crashes if the device needs to be reset mid-operation.
See "2.1 Device Status Field" in the VIRTIO 1.0 specification for
details.

Pull core kernel fixes from Ingo Molnar:
"This contains the nohz/atomic cleanup/fix for the fetch_or() ugliness
you noted during the original nohz pull request, plus there's also
misc fixes:
- fix liblockdep build bug
- fix uapi header build bug
- print more lockdep hash collision info to help debug recent reports
of hash collisions
- update MAINTAINERS email address"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
MAINTAINERS: Update my email address
locking/lockdep: Print chain_key collision information
uapi/linux/stddef.h: Provide __always_inline to userspace headers
tools/lib/lockdep: Fix unsupported 'basename -s' in run_tests.sh
locking/atomic, sched: Unexport fetch_or()
timers/nohz: Convert tick dependency mask to atomic_t
locking/atomic: Introduce atomic_fetch_or()
Right now exynos is exposing DPI as a TMDS encoder and VGA connector,
which seems rather misleading. This isn't just an internal detail,
since xrandr actually exposes "VGA" as the output name. Define some
new enums so that vc4's DPI can have a more informative name.
I considered other names for the connector as well. For VC4, the
Adafruit DPI kippah takes the 28 GPIO pins and routes them to a
standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely
identify an ordering of pins (apparently some other orderings exist),
doesn't explain things as well for the user (who, if anything, knows
their product is a DPI kippah/panel combo), and actually doesn't have
to exist (one could connect the 28 GPIOs directly to something else).
Simply "DPI" seems like a good compromise name to distinguish from the
HDMI, DSI, and TV connectors .

libdrm: Make some drm headers compatible with gcc -std=c89 -pedantic
The following minor changes were needed to these headers:
* Convert // comments to /* */
* No , after final member of enum
With these changes, these header files can be included by a program that
is built with gcc options:
-std=c89 -Werror -pedantic

Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl
and tunnel_label members explicit. No issue has been observed, and
gcc/llvm does padding for the old struct already, where tunnel_label
was not yet present, so the current code works, but since it's part
of uapi, make sure we don't introduce holes in structs.
Therefore, add tunnel_ext that we can use generically in future
(f.e. to flag OAM messages for backends, etc). Also add the offset
to the compat tests to be sure should some compilers not padd the
tail of the old version of bpf_tunnel_key.

We can't use <drm/*.h> because that upsets the serach paths in libdrm.
Also, drop the circular inclusion in drm_mode.h.
v2: Actually change the right headers.
v3: Drop the #include removal per Emil's request.

virtual is a protected keyword in C++ and can't be used at all. Ugh.
This aligns the kernel versions of the drm headers with the ones in
libdrm.
v2: Also annote with __user, as request by Emil&Ilia.
