dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.
A simple test case demonstrates this quite nicely:
int main(int argc, char *argv[])
{
struct iovec iov;
int fd;
fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
posix_memalign(&iov.iov_base, 4096, 4096);
iov.iov_len = 4096;
preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
return 0;
}
which will instantly spew:

where in fact it is dm itself that attempts to allocate a bio clone with
GFP_NOIO under the rcu read lock, regardless of the request type.
Fix this by getting rid of the special casing for REQ_NOWAIT, and just
use the normal SRCU protected table lookup. Get rid of the bio based
table locking helpers at the same time, as they are now unused.

Invalidate instruction and State cache bit using INDIRECT_CTX on
every gpu context switch for gen12.
The goal of this workaround is to actually perform an explicit
invalidation of that cache (by re-writing the register) during every GPU
context switch, which is accomplished via a "workaround batchbuffer"
that's attached to the context via INDIRECT_CTX. (Matt Roper)

Remove the i915 specific i2c-N symlink from HDMI connectors.
This was added to sort of mirror the DP connectors that alreayd
had their aux ch based i2c adapter sitting beneath them in the
sysfs hierarchy. But now that we have the standard "ddc" symlink
approach provided by the core let's switch to that fully.
I don't think anything beyond igt depends on this.

Let's also reorder intel_dp_aux_init() vs. drm_connector_init_with_ddc()
a bit to make sure the i2c aux ch is at least somewhat populated
before we pass it on, though drm_connector_init_with_ddc() does
not actually do anything with it.

Populate connector->ddc, and thus create the "ddc" symlink
in sysfs for analog VGA connectors.
As a bonus we can replace a bunch of intel_gmbus_get_adapter()
lookups with just the connector->ddc pointer. Sadly one extra
lookup still remains due to the g4x DVI-I shenanigans. We could
perhaps consider borrowing the ddc proxy idea from SDVO to deal
with that in a perhaps nicer way, but can't really be bothered
right now at least. Also not sure exposing such a dual ddc bus
to userspace would be quite wise.

i2c adapter ("i2c", "adapter", etc.) to just "ddc".
This differentiates it from the various other i2c

Currently drm_sysfs_connector_add() attempts to register
the "ddc" symlink (based one connector->ddc) before the
driver's .early_register() hook has been called. That is
too early for i915 which only fully registers the aux ch
and associated i2c bus from said hook (to prevent half
initialized stuff getting exposed to userspace). This
causes my attempt at using drm_connector_init_with_ddc()
to fail, and the entire connector disappears from sysfs
on account of sysfs_create_link() failing.
To fix that split the sysfs symlink stuff into separate
functions (drm_sysfs_connector_add_late() and
drm_sysfs_connector_remove_early()) which are called
on the opposite side of the .later_register() and
.early_unregister() hooks.

Use the standard onion peeling approach and call
drm_debugfs_connector_remove() and
drm_sysfs_connector_remove() in the reverse order in
drm_connector_unregister() than what we called their
add counterpartse in drm_connector_register().
The error unwiding in drm_connector_register() is
already doing this the correct way around.

Commit:
5a5d7e9bad ("cpuidle: lib/bug: Disable rcu_is_watching() during WARN/BUG")
amended warn_slowpath_fmt() to disable preemption until the WARN splat
has been emitted.
However the commit neglected to reenable preemption in the !fmt codepath,
i.e. when a WARN splat is emitted without additional format string.
One consequence is that users may see more splats than intended. E.g. a
WARN splat emitted in a work item results in at least two extra splats:
BUG: workqueue leaked lock or atomic
(emitted by process_one_work())
BUG: scheduling while atomic
(emitted by worker_thread() -> schedule())
Ironically the point of the commit was to *avoid* extra splats. ;)
Fix it.

WARNING: ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP
Also fixed minor typo
Signed-off-by: Steve French <stfrench@microsoft.com>
When a CRC error occurs, the HBA asserts an interrupt to indicate an
interface fatal error (PxIS.IFS). The ISR clears PxIE and PxIS, then
does error recovery. If the adapter receives another SDB FIS
with an error (PxIS.TFES) from the device before the start of the EH
recovery process, the interrupt signaling the new SDB cannot be
serviced as PxIE was cleared already. This in turn results in the HBA
inability to issue any command during the error recovery process after
setting PxCMD.ST to 1 because PxIS.TFES is still set.
According to AHCI 1.3.1 specifications section 6.2.2, fatal errors
notified by setting PxIS.HBFS, PxIS.HBDS, PxIS.IFS or PxIS.TFES will
cause the HBA to enter the ERR:Fatal state. In this state, the HBA
shall not issue any new commands.
To avoid this situation, introduce the function
ahci_port_clear_pending_irq() to clear pending interrupts before
executing a COMRESET. This follows the AHCI 1.3.1 - section 6.2.2.2
specification.

Some devices are reporting controller ready mode support, but return 0
for CRTO. These devices require a much higher time to ready than that,
so they are failing to initialize after the driver starter preferring
that value over CAP.TO.
The spec requires that CAP.TO match the appropritate CRTO value, or be
set to 0xff if CRTO is larger than that. This means that CAP.TO can be
used to validate if CRTO is reliable, and provides an appropriate
fallback for setting the timeout value if not. Use whichever is larger.

Commit bc840ea5f9 ("thermal: core: Do not handle trip points with

disabled trip point check in handle_thermal_trip(), but that check was
added at a point when the trip structure has not been initialized yet.
This may cause handle_thermal_trip() to skip a valid trip point in some
cases, so fix it by moving the check to a suitable place, after
__thermal_zone_get_trip() has been called to populate the trip
structure.
