This converts the driver to use the new tasklet API introduced in
commit 12cc923f1c ("tasklet: Introduce new initialization API")
It is unfortunate that we need to add a pointer to the driver context to
get back to the usbnet device, but the space will be reclaimed once
there are no more users of the old API left and we can remove the data
value and flag from the tasklet struct.

Added "ckpt_thread_ioprio" sysfs node to give a way to change checkpoint
merge daemon's io priority. Its default value is "be,3", which means
"BE" I/O class and I/O priority "3". We can select the class between "rt"
and "be", and set the I/O priority within valid range of it.
"," delimiter is necessary in between I/O class and priority number.

We've added a new mount options, "checkpoint_merge" and "nocheckpoint_merge",
which creates a kernel daemon and makes it to merge concurrent checkpoint
requests as much as possible to eliminate redundant checkpoint issues. Plus,
we can eliminate the sluggish issue caused by slow checkpoint operation
when the checkpoint is done in a process context in a cgroup having
low i/o budget and cpu shares. To make this do better, we set the
default i/o priority of the kernel daemon to "3", to give one higher
priority than other kernel threads. The below verification result
explains this.
The basic idea has come from https://opensource.samsung.com.
[Verification]
Android Pixel Device(ARM64, 7GB RAM, 256GB UFS)
Create two I/O cgroups (fg w/ weight 100, bg w/ wight 20)
Set "strict_guarantees" to "1" in BFQ tunables
In "fg" cgroup,
- thread A => trigger 1000 checkpoint operations
"for i in `seq 1 1000`; do touch test_dir1/file; fsync test_dir1;
done"
- thread B => gererating async. I/O
"fio --rw=write --numjobs=1 --bs=128k --runtime=3600 --time_based=1

In "bg" cgroup,
- thread C => trigger repeated checkpoint operations
"echo $$ > /dev/blkio/bg/tasks; while true; do touch test_dir2/file;
fsync test_dir2; done"
We've measured thread A's execution time.

This patch adds support to verifier tests to check for a succession of
verifier log messages on program load failure. This makes the errstr
field work uniformly across REJECT and VERBOSE_ACCEPT checks.
This patch also increases the maximum size of a message in the series of
messages to test from 80 chars to 200 chars. This is in order to keep
existing tests working, which sometimes test for messages larger than 80
chars (which was accepted in the REJECT case, when testing for a single
message, but not in the VERBOSE_ACCEPT case, when testing for possibly
multiple messages).
And example of such a long, checked message is in bounds.c: "R1 has
unknown scalar with mixed signed bounds, pointer arithmetic with it
prohibited for !root"

Add a macro cond_yield that branches to a specified label when called if
the TIF_NEED_RESCHED flag is set and decreasing the preempt count would
make the task preemptible again, resulting in a schedule to occur. This
can be used by kernel mode SIMD code that keeps a lot of state in SIMD
registers, which would make chunking the input in order to perform the
cond_resched() check from C code disproportionately costly.

The 32-bit Amlogic Meson SoCs embed an ARC processor in the Always-On
power domain which is typically used for managing system suspend. The
memory for this ARC core is taken from the AHB SRAM area. Depending on
the actual SoC a different ARC core is used:
- Meson6 and earlier: some ARCv1 ISA based core (probably an ARC625)
- Meson8 and later: an ARC EM4 (ARCv2 ISA) based core
Add the device-tree node for this remote-processor along with the
required SRAM sections, clocks and reset-lines. Also use the
SoC-specific compatible string to manage any differences (should
they exist).
On Meson8, Meson8b and Meson8m2 the "secbus2" IO region is needed as
some bits need to be programmed there. Add this IO region for those
SoCs as well.

The Meson8/Meson8b/Meson8m2 SoCs have a register bank called SECBUS2 which
contains registers for various IP blocks such as pin-controller bits for
the BSD_EN and TEST_N GPIOs as well as some AO ARC core control bits.
The registers can be accessed directly when not running in "secure mode".
When "secure mode" is enabled then these registers have to be accessed
through secure monitor calls.
So far these SoCs are always known to boot in "non-secure mode".
Add a binding documentation using syscon (as these registers are shared
across different IPs) for the SECBUS2 registers.

soc-pcm has dpcm_runtime_merge_xxx() functions,
but uses parameters are very verbose.
dpcm_runtime_merge_format(..., &runtime->hw.formats);
dpcm_runtime_merge_chan(..., &runtime->hw.channels_min,
&runtime->hw.channels_max);
dpcm_runtime_merge_rate(..., &runtime->hw.rates,
&runtime->hw.rate_min,
&runtime->hw.rate_max);
We want to replace it into
dpcm_runtime_merge_format(..., runtime);
dpcm_runtime_merge_chan(..., runtime);
dpcm_runtime_merge_rate(..., runtime);
This patch do it.

soc_new_pcm() implementation is very long / verbose / complex,
thus, it is very difficult to read.
If we read it carefully, we can notice that it is consisted by
int soc_new_pcm(...)
{
(1) judging playback/caputre part
(2) creating the PCM part
(3) setup pcm/rtd part
}
This patch adds new soc_create_pcm() for (2) part
and offload it from snd_pcm_new().

Keep the current value of the updated log tail in the super block as
sb_log_flush_tail instead of computing it on the fly. This avoids
unnecessary sd_ail_lock taking and cleans up the code.

Use a tighter bound for the number of blocks required by transactions in
gfs2_trans_begin: in the worst case, we'll have mixed data and metadata,
so we'll need a log desciptor for each type.

Wake up log waiters in gfs2_log_release when log space has actually become
available. This is a much better place for the wakeup than gfs2_logd.
Check if enough log space is immeditely available before anything else. If
there isn't, use io_wait_event to wait instead of open-coding it.

Commit 588bff95c9 added gfs2_write_log_header() and started using it in
clean_journal(), with an additional call to log_flush_wait() at the end of
gfs2_write_log_header() which is unnecessary for clean_journal(). Move
that call out of gfs2_write_log_header() to restore the previous behavior.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
Move the read locking of sd_log_flush_lock from gfs2_log_reserve to
gfs2_trans_begin, and its unlocking from gfs2_log_release to
gfs2_trans_end. Use gfs2_log_release in two places in which it was open
coded before.
