The only time we actually leave the path spinning is if we're truncating
a small amount and don't actually free an extent, which is not a common
occurrence. We have to set the path blocking in order to add the
delayed ref anyway, so the first extent we find we set the path to
blocking and stay blocking for the duration of the operation. With the
upcoming file extent map stuff there will be another case that we have
to have the path blocking, so just swap to blocking always.
Note: this patch also fixes a warning after 28553fa992 ("Btrfs: fix
race between shrinking truncate and fiemap") got merged that inserts
extent locks around truncation so the path must not leave spinning locks
after btrfs_search_slot.

With VHE, running a vCPU always requires the sequence:
1. kvm_arm_vhe_guest_enter();
2. kvm_vcpu_run_vhe();
3. kvm_arm_vhe_guest_exit()
... and as we invoke this from the shared arm/arm64 KVM code, 32-bit arm
has to provide stubs for all three functions.
To simplify the common code, and make it easier to make further
modifications to the arm64-specific portions in the near future, let's
fold kvm_arm_vhe_guest_enter() and kvm_arm_vhe_guest_exit() into
kvm_vcpu_run_vhe().
The 32-bit stubs for kvm_arm_vhe_guest_enter() and
kvm_arm_vhe_guest_exit() are removed, as they are no longer used. The

This patch adds the recursive parsing in parse_term_effect_unit().
It doesn't add anything in the audio unit parser itself, and the
effect unit itself is still skipped, though.

X86 abuses the function which retrieves the architecture specific clock

because this is invoked on every tick when the VDSO data is updated.

The da9062 hw has a minimum ping cool down phase of at least 200ms. The
driver takes that into account by setting the min_hw_heartbeat_ms to
300ms and the core guarantees that the hw limit is observed for the
ping() calls. But the core can't guarantee the required minimum ping
cool down phase if a stop() command is send immediately after the ping()
command. So it is not allowed to ping the watchdog within the stop()
command as the driver does. Remove the ping can be done without doubts
because the watchdog gets disabled anyway and a (re)start resets the
watchdog counter too.

Many functions carry the enable_per_layer_report argument. This is a
bool value indicating the error information contains some location
data where the error occurred. This can easily being determined by
checking the pos[] array for values. Negative values indicate there is
no location available. So if the top layer is negative, the error
location is unknown.
Just check if the top layer is negative and remove
enable_per_layer_report as function argument and also from struct

There is a limitation to report only EDAC_MAX_LABELS in e->label of
the error descriptor. This is to prevent a potential string overflow.
The current implementation falls back to "any memory" in this case and
also stops all further processing to find a unique row and channel of
the possible error location.
Reporting "any memory" is wrong as the memory controller reported an
error location for one of the layers. Instead, report "unknown memory"
and also do not break early in the loop to further check row and channel
for uniqueness.

true for the case of (!e->enable_per_layer_report). Here, a DIMM was

edac_mc_alloc() is huge. Factor out code by moving it to the two new
functions edac_mc_alloc_csrows() and edac_mc_alloc_dimms(). Do not
move code yet for better review.

Without selftests enabled, I915_SELFTEST_ONLY becomes a dummy,
generating a bare '0'. This causes the compiler to complain about a
useless line, and while we could use I915_SELFTEST_DECLARE instead, it
is a bit messier. Move the selftest-only code to a helper and make that
conditional on having selftests enabled.
