This adds a missing break statement to VFIO_DEVICE_SET_IRQS handler
without which vfio_pci_set_err_trigger() would never be called.
While we are here, add another "break" to VFIO_PCI_REQ_IRQ_INDEX case
so if we add more indexes later, we won't miss it.

Dave Chinner reported that commit 4d94246699 ("mm: convert
p[te|md]_mknonnuma and remaining page table manipulations") slowed down
his xfsrepair test enormously. In particular, it was using more system
time due to extra TLB flushing.
The ultimate reason turns out to be how the change to use the regular
page table accessor functions broke the NUMA grouping logic. The old
special mknuma/mknonnuma code accessed the page table present bit and
the magic NUMA bit directly, while the new code just changes the page
protections using PROT_NONE and the regular vma protections.
That sounds equivalent, and from a fault standpoint it really is, but a
subtle side effect is that the *other* protection bits of the page table
entries also change. And the code to decide how to group the NUMA
entries together used the writable bit to decide whether a particular
page was likely to be shared read-only or not.
And with the change to make the NUMA handling use the regular permission
setting functions, that writable bit was basically always cleared for
private mappings due to COW. So even if the page actually ends up being
written to in the end, the NUMA balancing would act as if it was always
shared RO.
This code is a heuristic anyway, so the fix - at least for now - is to
instead check whether the page is dirty rather than writable. The bit
doesn't change with protection changes.
NOTE! This also adds a FIXME comment to revisit this issue,
Not only should we probably re-visit the whole "is this a shared
read-only page" heuristic (we might want to take the vma permissions
into account and base this more on those than the per-page ones, and
also look at whether the particular access that triggers it is a write
or not), but the whole COW issue shows that we should think about the
NUMA fault handling some more.
For example, maybe we should do the early-COW thing that a regular fault
does. Or maybe we should accept that while using the same bits as
PROTNONE was a good thing (and got rid of the specual NUMA bit), we
might still want to just preseve the other protection bits across NUMA
faulting.
Those are bigger questions, left for later. This just fixes up the
heuristic so that it at least approximates working again. More analysis
and work needed.

("i2c: core: Dispose OF IRQ mapping at client removal time")
Calling irq_dispose_mapping() will destroy the mapping and disassociate
the IRQ from the IRQ chip to which it belongs. Keeping it is OK, because
existent mappings are reused properly.
Also, this commit breaks drivers using devm* for IRQ management on
OF-based systems because devm* cleanup happens in device code, after
bus's remove() method returns.

Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers. That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get(). This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place. The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.
That said, the struct clk pointer comparing in the code doesn't work any
more. Call helper function clk_is_match() instead to fix the problem.

Some drivers compare struct clk pointers as a means of knowing
if the two pointers reference the same clock hardware. This behavior is
dubious (drivers must not dereference struct clk), but did not cause any
regressions until the per-user struct clk patch was merged. Now the test
for matching clk's will always fail with per-user struct clk's.
clk_is_match is introduced to fix the regression and prevent drivers
from comparing the pointers manually.

While the original commit makes it easier to run cpupower from the
local build directory, it also leaves the binary with a rather poor
rpath of './' in it after it is installed on a system via 'make install'.
This is considered bad practice and can cause cpupower to fail in
rpmbuild with the following error:

error: Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)

cppcheck on lines 917 and 977 show an ineffective assignment

[drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c:977]:
(warning) Assignment of function parameter has no effect
outside the function. Did you forget dereferencing it?
On a successful DMA buffer lookup, the dma buffer pointer is
assigned, however, on failure it currently is left in an
undefined state.
The original intention in the error exit path was to nullify
the pointer on an error (which the original code failed to
do properly). This patch fixes this also ensures all failure
paths nullify the buffer pointer on the error return.
Fortunately the callers to vmw_translate_mob_ptr and
vmw_translate_guest_ptr are checking on a return status and not
on the dma buffer pointer, so the original code worked.

Add a check at the beginning to see if the syscall is present, and if

When we run on a system that doesn't implement the syscall we will get

A normal wait adds to the front of the tail. By doing something
similar to fence_default_wait the fence code can run without racing.
This is a complete fix for "panic on suspend from KDE with radeon",
and a partial fix for "Radeon: System pauses on TAHITI". On tahiti
si_irq_set needs to be fixed too, to completely flush the writes
before radeon_fence_activity is called in radeon_fence_enable_signaling.

The exact steps provided for submitting binding patches can be read

The unittest fails to link if I2C or I2C_MUX is a loadable module:
drivers/built-in.o: In function `selftest_i2c_mux_remove':
unittest.c:(.text+0xb0ce4): undefined reference to `i2c_del_mux_adapter'
This changes the newly added IS_ENABLED() checks to use IS_BUILTIN()
instead, which evaluates to false if the other driver is a module.

Support for devicetree serial consoles via 'stdout-path' causes
bootconsoles to be disabled when the vt dummy console loads, since
there is no preferred console (the preferred console is not added
until the device is probed).
Ensure there is at least a preferred console, even if never matched.
