Remove compat ALSA card, which has overlapping functionality with the
two other cards described by the driver (HDMI and headphones)
This handles TODO item "Revisit multi-cards options and PCM route mixer
control".
Move the S/PDIF device that was part of the compat ALSA card to the HDMI
card.
Only enable headphones card by default, because HDMI breaks when using
both vc4 and bcm2835-audio with HDMI card enabled.

Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so.
rtllib_sta_ps() and ieee80211_sta_ps() will now run in process context
and have further concurrency (tasklets being serialized among themselves),
but this is done holding the ieee->lock, so it should be fine.

The execution of the SME event will now occur in task context. There
are, however, changes in concurrency. Workqueues, unlike tasklets,
are not serialized among themselves and can run concurrently
updating sme_i.qhead. However, the current code is already exposed
in same ways, regardless of the deferral mechanism, in that
hostif_sme_enqueue() does unserialized enqueues updating sme_i.qtail.
Also get rid of the bogus (power save) tasklet enabling, as it
is never disabled to begin with.

They are the final bits in the removal of the default_attrs field in

changes to do this came in through different development trees, and then
one new user snuck in. So this series has 2 changes:
- removal of the default_attrs field in the powerpc/pseries/vas
code. Change has been acked by the PPC maintainers to come
through this tree
- removal of default_attrs from struct kobj_type now that all
in-kernel users are removed. This cleans up the kobject code
a little bit and removes some duplicated functionality that

groups.)

perf doesn't read stderr then progress stops with perf waiting for

The `perf --list-cmds` output prints only internal commands, although
there is no reason for that from users' perspective.
Adding the external commands to commands array with NULL function

Keep the logic to error out on inadequate input from fuzzing.

The 'perf bench epoll' testcase fails on systems with more than 1K CPUs.
Testcase: perf bench epoll all
Result snippet:
<<>>
Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs.
perf: pthread_create: No such file or directory
<<>>
In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads
from respective bench_epoll_* function. Though the logs shows direct
failure from pthread_create, the actual failure is from
"sched_setaffinity" returning EINVAL (invalid argument).
This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
using the CPU_*_S macros.
Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC
to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the
mask.

The 'perf bench futex' testcase fails on systems with more than 1K CPUs.
Testcase: perf bench futex all
Failure snippet:
<<>>Running futex/hash benchmark...
perf: pthread_create: No such file or directory
<<>>
All the futex benchmarks (ie hash, lock-api, requeue, wake,
wake-parallel), pthread_create is invoked in respective bench_futex_*
function. Though the logs shows direct failure from pthread_create,
strace logs showed that actual failure is from "sched_setaffinity"
returning EINVAL (invalid argument).
This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
using the CPU_*_S macros.
Patch addresses this by fixing all the futex benchmarks to use CPU_ALLOC
to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the
mask.

eprintf() does not expect va_list as the type of the 4th parameter.
Use veprintf() because it does.

Since commit bb30acae4c ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't allow opening the file unless one of the events has
PERF_SAMPLE_DATA_SRC set.
SPE doesn't have this set even though synthetic memory data is generated
after it is decoded. Fix this issue by setting DATA_SRC on SPE events.
This has no effect on the data collected because the SPE driver doesn't
do anything with that flag and doesn't generate samples.
