The bindings for Qualcomm opp levels changed after being Acked but
before landing. Thus the code in the GPU driver that was relying on
the old bindings is now broken.
Let's change the code to match the new bindings by adjusting the old
string 'qcom,level' to the new string 'opp-level'. See the patch
("dt-bindings: opp: Introduce opp-level bindings").
NOTE: we will do additional cleanup to totally remove the string from
the code and use the new dev_pm_opp_get_level() but we'll do it in a
future patch. This will facilitate getting the important code fix in
sooner without having to deal with cross-maintainer dependencies.
This patch needs to land before the patch ("arm64: dts: sdm845: Add
gpu and gmu device nodes") since if a tree contains the device tree
patch but not this one you'll get a crash at bootup.

This reverts commit 574823bfab.
It turns out that my hope that we could just remove the code that
exposes the cache residency status from mincore() was too optimistic.
There are various random users that want it, and one example would be
the Netflix database cluster maintenance. To quote Josh Snyder:
"For Netflix, losing accurate information from the mincore syscall
would lengthen database cluster maintenance operations from days to
months. We rely on cross-process mincore to migrate the contents of a
page cache from machine to machine, and across reboots.
To do this, I wrote and maintain happycache [1], a page cache
dumper/loader tool. It is quite similar in architecture to pgfincore,
except that it is agnostic to workload. The gist of happycache's
operation is "produce a dump of residence status for each page, do
some operation, then reload exactly the same pages which were present
before." happycache is entirely dependent on accurate reporting of the
in-core status of file-backed pages, as accessed by another process.
We primarily use happycache with Cassandra, which (like Postgres +
pgfincore) relies heavily on OS page cache to reduce disk accesses.
Because our workloads never experience a cold page cache, we are able
to provision hardware for a peak utilization level that is far lower
than the hypothetical "every query is a cache miss" peak.
A database warmed by happycache can be ready for service in seconds
(bounded only by the performance of the drives and the I/O subsystem),
with no period of in-service degradation. By contrast, putting a
database in service without a page cache entails a potentially
unbounded period of degradation (at Netflix, the time to populate a
single node's cache via natural cache misses varies by workload from
hours to weeks). If a single node upgrade were to take weeks, then
upgrading an entire cluster would take months. Since we want to apply
security upgrades (and other things) on a somewhat tighter schedule,
we would have to develop more complex solutions to provide the same
functionality already provided by mincore.
At the bottom line, happycache is designed to benignly exploit the
same information leak documented in the paper [2]. I think it makes
perfect sense to remove cross-process mincore functionality from
unprivileged users, but not to remove it entirely"
We do have an alternate approach that limits the cache residency
reporting only to processes that have write permissions to the file, so
we can fix the original information leak issue that way. It involves
_adding_ code rather than removing it, which is sad, but hey, at least
we haven't found any users that would find the restrictions
unacceptable.
So revert the optimistic first approach to make room for that alternate
fix instead.

So modify thing to on initialize on the first use. There was already

Some IPMI modules (e.g. ibmpex_msg_handler()) will have ipmi_usr_hdlr
handlers that call ipmi_free_recv_msg() directly. This will essentially
kfree(msg), leading to use-after-free.
This does not happen in the ipmi_devintf module, which will queue the

channel and addr->channel are indirectly controlled by user-space,
hence leading to a potential exploitation of the Spectre variant 1
vulnerability.
These issues were detected with the help of Smatch:

drivers/char/ipmi/ipmi_msghandler.c:2260 check_addr() warn: potential spectre issue 'intf->addrinfo' [r] (local cap)
Fix this by sanitizing channel and addr->channel before using them to
index user->intf->addrinfo and intf->addrinfo, correspondingly.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The risk of redundant IO accounting was not taken into consideration
when commit 18a25da843 ("dm: ensure bio submission follows a
depth-first tree walk") introduced IO splitting in terms of recursion
via generic_make_request().
Fix this by subtracting the split bio's payload from the IO stats that
were already accounted for by start_io_acct() upon dm_make_request()
entry. This repeat oscillation of the IO accounting, up then down,
isn't ideal but refactoring DM core's IO splitting to pre-split bios
_before_ they are accounted turned out to be an excessive amount of
change that will need a full development cycle to refine and verify.
Before this fix:
/dev/mapper/stripe_dev is a 4-way stripe using a 32k chunksize, so
bios are split on 32k boundaries.
# fio --name=16M --filename=/dev/mapper/stripe_dev --rw=write --bs=64k --size=16M \
--iodepth=1 --ioengine=libaio --direct=1 --refill_buffers
with debugging added:
[103898.310264] device-mapper: core: start_io_acct: dm-2 WRITE bio->bi_iter.bi_sector=0 len=128
[103898.318704] device-mapper: core: __split_and_process_bio: recursing for following split bio:
[103898.329136] device-mapper: core: start_io_acct: dm-2 WRITE bio->bi_iter.bi_sector=64 len=64
...
16M written yet 136M (278528 * 512b) accounted:
# cat /sys/block/dm-2/stat | awk '{ print $7 }'
278528
After this fix:
16M written and 16M (32768 * 512b) accounted:
# cat /sys/block/dm-2/stat | awk '{ print $7 }'
32768

As the other ceph related files are licensed under the GPL v2 only, it's

con_fault() can transition the connection into STANDBY right after
ceph_con_keepalive() clears STANDBY in clear_standby():

ceph_con_keepalive()
mutex_lock(&con->mutex)
clear_standby(con)

if KEEPALIVE_PENDING isn't set

...
mutex_unlock(&con->mutex)
set KEEPALIVE_PENDING
set WRITE_PENDING
This triggers warnings in clear_standby() when either ceph_con_send()
or ceph_con_keepalive() get to clearing STANDBY next time.
I don't see a reason to condition queue_con() call on the previous
value of KEEPALIVE_PENDING, so move the setting of KEEPALIVE_PENDING
into the critical section -- unlike WRITE_PENDING, KEEPALIVE_PENDING
could have been a non-atomic flag.
