RIP page_cache_tree_insert+0xf1/0x100
This is a long-standing bug in the way shadow entries are accounted in
the radix tree nodes. The shrinker needs to know when radix tree nodes
contain only shadow entries, no pages, so node->count is split in half
to count shadows in the upper bits and pages in the lower bits.
Unfortunately, the radix tree implementation doesn't know of this and
assumes all entries are in node->count. When there is a shadow entry
directly in root->rnode and the tree is later extended, the radix tree
implementation will copy that entry into the new node and and bump its
node->count, i.e. increases the page count bits. Once the shadow gets
removed and we subtract from the upper counter, node->count underflows
and triggers the warning. Afterwards, without node->count reaching 0
again, the radix tree node is leaked.
Limit shadow entries to when we have actual radix tree nodes and can
count them properly. That means we lose the ability to detect refaults
from files that had only the first page faulted in at eviction time.
Fixes: 449dd6984d0e ("mm: keep page cache radix tree nodes in check")

Pull clk framework updates from Stephen Boyd:
"The core clk framework changes are small again. They're mostly minor
fixes that weren't causing enough problems (or any problems when we're
just clarifying things) to warrant sending outside the merge window.
The majority of changes are in drivers for various SoCs. Full details
are in the logs, but here's the summary.
Core:
- Better support for DeviceTree overlays with the addition of the
CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a
device node that matched during of_clk_init(), unless the driver
uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows
overlays to work cleanly for drivers that must probe before the
device model is ready, and also after it's ready when an overlay is
loaded.
- Clarification in the code around how clk_hw pointers are returned
from of clk providers
- Proper migration of prepare/enable counts to parents when the clk
tree is constructed
New Drivers:
- Socionext's UniPhier SoCs
- Loongson1C
- ZTE ZX296718
- Qualcomm MDM9615
- Amlogic GXBB AO clocks and resets
- Broadcom BCM53573 ILP
- Maxim MAX77620
Updates:
- Four Allwinner SoCs are migrated to the new style clk driver (A31,
A31s, A23 and A33)
- Exynos 5xxx audio and DRAM clks
- Loongson1B AC97, DMA and NAND clks
- Rockchip DDR clks and rk3399 driver tweaks
- Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer
clks
- Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
- Amlogic GXBB MMC gate clks
- at91 sama5d4 sckc
- Removal of STiH415 and STiH416 clk support as the SoC is being
removed
- Rework of STiH4xx clk support for new style bindings
- Continuation of driver migration to clk_hw based registration APIs
- xgene PMD support

Due to the lack of parity in the way array fields have been named/
numbered, a mistake was made where more debug fields were declared
than actually existed. In doing so, 2 fields were added, which
although unclear, were already declared in the array. The result
was that the latter declarations trashed the former ones.
This patch places the array back in the correct order and removes
the offending NULL entries.
While we're at it, let's ensure this doesn't happen again by naming
each field properly and add a new *_LAST define to describe how
many fields there should be.

When building with -Woverride-init, we get a warning about an incorrect
initializer:
drivers/mfd/rk808.c:244:8: error: initialized field overwritten [-Werror=override-init]
[RK818_IRQ_DISCHG_ILIM] = {
This is clearly a mistake, as both RK818_IRQ_DISCHG_ILIM and RK818_IRQ_USB_OV
are defined as '7', but they refer to different register bits. Changing
RK818_IRQ_DISCHG_ILIM to 15 is consistent with how all other 14 interrupts are
handled here, so I'm assuming this is what it should have been.

order to add interrupt handling for each tps65217's subsystem. IRQ
resources have been added for charger subsystem to be able to notify about

This patch adds common driver for the Top block of the Samsung Exynos
SoC Low Power Audio Subsystem. This is a minimal driver which prepares
resources for IP blocks like I2S, audio DMA and UART and exposes
a regmap for the Top block registers. Also system power ops are added
to ensure the Audio Subsystem is operational after system suspend/resume
cycle.

set_bit() and clear_bit() take the bit number so this code is really
doing "1 << (1 << irq)" which is a double shift bug. It's done
consistently so it won't cause a problem unless "irq" is more than 4.

That just generally kills the machine, and makes debugging only much
harder, since the traces may long be gone.
Debugging by assert() is a disease. Don't do it. If you can continue,
you're much better off doing so with a live machine where you have a
much higher chance that the report actually makes it to the system logs,
rather than result in a machine that is just completely dead.
The only valid situation for BUG_ON() is when continuing is not an
option, because there is massive corruption. But if you are just
verifying that something is true, you warn about your broken assumptions
(preferably just once), and limp on.

Pull perf updates from Ingo Molnar:
"The main kernel side changes were:
- uprobes enhancements (Masami Hiramatsu)
- Uncore group events enhancements (David Carrillo-Cisneros)
- x86 Intel: Add support for Skylake server uncore PMUs (Kan Liang)
- x86 Intel: LBR cleanups and enhancements, for better branch
annotation tracking (Peter Zijlstra)
- x86 Intel: Add support for PTWRITE and power event tracing
(Alexander Shishkin)
- ... various fixes, cleanups and smaller enhancements.
Lots of tooling changes - a couple of highlights:
- Support event group view with hierarchy mode in 'perf top' and
'perf report' (Namhyung Kim)
e.g.:
$ perf record -e '{cycles,instructions}' make
$ perf report --hierarchy --stdio
...
# Overhead Command / Shared Object / Symbol
# ...................... ..................................
...
25.74% 27.18%sh
19.96% 24.14%libc-2.24.so
9.55% 14.64%[.] __strcmp_sse2
1.54% 0.00%[.] __tfind
1.07% 1.13%[.] _int_malloc
0.95% 0.00%[.] __strchr_sse2
0.89% 1.39%[.] __tsearch
0.76% 0.00%[.] strlen
- Add branch stack / basic block info to 'perf annotate --stdio',
where for each branch, we add an asm comment after the instruction
with information on how often it was taken and predicted. See
example with color output at:
http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png
(Peter Zijlstra)
- Add support for using symbols in address filters with Intel PT and
ARM CoreSight (hardware assisted tracing facilities) (Adrian
Hunter, Mathieu Poirier)
- Add support for interacting with Coresight PMU ETMs/PTMs, that are
IP blocks to perform hardware assisted tracing on a ARM CPU core
(Mathieu Poirier)
- Support generating cross arch probes, i.e. if you specify a vmlinux
file for different arch than the one in the host machine,
$ perf probe --definition function_name args
will generate the probe definition string needed to append to the
target machine /sys/kernel/debug/tracing/kprobes_events file, using
scripting (Masami Hiramatsu).
- Allow configuring the default 'perf report -s' sort order in
~/.perfconfig, for instance, "sym,dso" may be more fitting for
kernel developers. (Arnaldo Carvalho de Melo)
- ... plus lots of other changes, refactorings, features and fixes"
