drm/exynos: Fix dma-buf import
get_modes() callback might be called asynchronously from the DRM core and
it is not synchronized with bridge_enable(), which sets proper runtime PM
state of the main DP device. Fix this by calling pm_runtime_get_sync()
before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and
analogix_dp_transfer() to ensure that main DP device is runtime active
when doing any access to its registers.

With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
passed a refcount object that has its counter set to 0. In this driver,
this is a valid use case since we want to increment ->usecnt only when
the BO object starts to be used by real HW components and this is
definitely not the case when the BO is created.
Fix the problem by using refcount_inc_not_zero() instead of
refcount_inc() and fallback to refcount_set(1) when
refcount_inc_not_zero() returns false. Note that this 2-steps operation
is not racy here because the whole section is protected by a mutex
which guarantees that the counter does not change between the
refcount_inc_not_zero() and refcount_set() calls.

When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver
are contiguous, because of the underlying dma_alloc_attrs() function
provides only such buffers. In such case it makes no sense to keep

failures for buffer contiguity checks in the subsequent operations on GEM

drm: locking&new iterators for connector_list
we've went to extreme lengths to make sure connector iterations works
in any context, without introducing any additional locking context.
This worked, except for a small fumble in the implementation:
When we actually race with a concurrent connector unplug event, and
our temporary connector reference turns out to be the final one, then
everything breaks: We call the connector release function from
whatever context we happen to be in, which can be an irq/atomic
context. And connector freeing grabs all kinds of locks and stuff.
Fix this by creating a specially safe put function for connetor_iter,
which (in this rare case) punts the cleanup to a worker.

Previously I was under the impression that the scanline counter
reads 0 when the pipe is off. Turns out that's not correct, and
instead the scanline counter simply stops when the pipe stops, and
it retains it's last value until the pipe starts up again, at which
point the scanline counter jumps to vblank start.
These jumps can cause the timestamp to jump backwards by one frame.
Since we use the timestamps to guesstimage also the frame counter
value on gen2, that would cause the frame counter to also jump
backwards, which leads to a massice difference from the previous value.
The end result is that flips/vblank events don't appear to complete as
they're stuck waiting for the frame counter to catch up to that massive
difference.
Fix the problem properly by actually making sure the scanline counter
has started to move before we assume that it's safe to enable vblank
processing.

- A VDSO entry for instruction cache flushing has been added so
userspace can flush the instruction cache.
- The VDSO symbol versions for __vdso_cmpxchg{32,64} have been
removed, as those VDSO entries don't actually exist.
- __io_writes has been corrected to respect the given type.
- A new READ_ONCE in arch_spin_is_locked().
- __test_and_op_bit_ord() is now actually ordered.
- Various small fixes throughout the tree to enable allmodconfig to

- Removal of some dead code in our atomic support headers.

coverage.
I've dropped patches 8 and 10 from the original set:
* [PATCH 08/10] (RISC-V: Set __ARCH_WANT_RENAMEAT to pick up generic
version) has a better fix that I've sent out for review, we don't want
renameat.
* [PATCH 10/10] (input: joystick: riscv has get_cycles) has already been
taken into Dmitry Torokhov's tree.
This merge contains the user-visible, ABI-breaking changes that we want
to make sure we have in Linux before our first release. Highlights
include:
* VDSO entries for clock_get/gettimeofday/getcpu have been added. These
are simple syscalls now, but we want to let glibc use them from the
start so we can make them faster later.
* A VDSO entry for instruction cache flushing has been added so
userspace can flush the instruction cache.
* The VDSO symbol versions for __vdso_cmpxchg{32,64} have been removed,
as those VDSO entries don't actually exist.
Conflicts:
arch/riscv/include/asm/tlbflush.h
This patch set is the result of some feedback that filtered through
after our original patch set was reviewed, some of which was the result
of me missing some email. It contains:
* A new READ_ONCE in arch_spin_is_locked()
* __test_and_op_bit_ord() is now actually ordered
* Improvements to various comments
* Removal of some dead code
Whoops -- I must have just been being an idiot again. Thanks to Segher
for finding the bug :).

Introducing a new include/lib directory just for this file totally
messes up tab completion for include/linux, which is highly annoying.
Move it to include/linux where we have headers for all kinds of other
lib/ code as well.
