commit a307a1e6bc "cpufreq: s3c: use cpufreq_generic_init()"
accidentally broke cpufreq on s3c2410 and s3c2412.
These two platforms don't have a CPU frequency table and used to skip
calling cpufreq_table_validate_and_show() for them. But with the
above commit, we started calling it unconditionally and that will
eventually fail as the frequency table pointer is NULL.
Fix this by calling cpufreq_table_validate_and_show() conditionally
again.

As the block layer, since the conversion to blkmq, claims the host using a
context, a following nested call to mmc_claim_host(), which isn't using a
context, may hang.
Calling mmc_interrupt_hpi() and mmc_read_bkops_status() via the mmc block
layer, may suffer from this problem, as these functions are calling
mmc_claim|release_host().
Let's fix the problem by removing the calls to mmc_claim|release_host()
from the above mentioned functions and instead make the callers responsible
of claiming/releasing the host. As a matter of fact, the existing callers
already deals with it.

wake_klogd is a local variable in console_unlock(). The information
is lost when the console_lock owner using the busy wait added by
the commit dbdda842fe ("printk: Add console owner and waiter
logic to load balance console writes"). The following race is
possible:
CPU0 CPU1
console_unlock()
for (;;)
/* calling console for last message */
printk()
log_store()
log_next_seq++;
/* see new message */
if (seen_seq != log_next_seq) {
wake_klogd = true;
seen_seq = log_next_seq;
}
console_lock_spinning_enable();
if (console_trylock_spinning())
/* spinning */
if (console_lock_spinning_disable_and_check()) {
printk_safe_exit_irqrestore(flags);
return;
console_unlock()
if (seen_seq != log_next_seq) {
/* already seen */
/* nothing to do */
Result: Nobody would wakeup klogd.
One solution would be to make a global variable from wake_klogd.
But then we would need to manipulate it under a lock or so.
This patch wakes klogd also when console_lock is passed to the
spinning waiter. It looks like the right way to go. Also userspace
should have a chance to see and store any "flood" of messages.
Note that the very late klogd wake up was a historic solution.
It made sense on single CPU systems or when sys_syslog() operations
were synchronized using the big kernel lock like in v2.1.113.
But it is questionable these days.

Tuning can leave the IP in an active state (Buffer Read Enable bit set)
which prevents the entry to low power states (i.e. S0i3). Data reset will
clear it.
Generally tuning is followed by a data transfer which will anyway sort out
the state, so it is rare that S0i3 is actually prevented.

This patch fixes this by trying of_find_spi_gpio() or

Commits c858233902 ("gpio: of: Support SPI nonstandard GPIO properties")
and 6a537d4846 ("gpio: of: Support regulator nonstandard GPIO
properties") have introduced a regression in the way error codes from
of_get_named_gpiod_flags are handled.
Previously, those errors codes were returned immediately, but the two
commits mentioned above are now overwriting the error pointer, meaning that
whatever value has been returned will be dropped in favor of whatever the
two new functions will return.
This might not be a big deal except for EPROBE_DEFER, on which GPIOlib
customers will depend on, and that will now be returned as an hard error
which means that they will not probe anymore, instead of gently deferring
their probe.
Since EPROBE_DEFER basically means that we have found a valid property but
there was no GPIO controller registered to handle it, fix this issues by
returning it as soon as we encounter it.

Discrete TPMs are often connected over slow serial buses which, on
some platforms, can have glitches causing bit flips. In all the
driver _recv() functions, we need to use a u32 to unmarshal the
response size, otherwise a bit flip of the 31st bit would cause the
expected variable to go negative, which would then try to read a huge
amount of data. Also sanity check that the expected amount of data is
large enough for the TPM header.

Commit 343a8d17fa (cpufreq: scpi: remove arm_big_little dependency)
changed the cpufreq driver on juno from arm_big_little to scpi.
The scpi set_target function does not call the frequency-invariance
setter function arch_set_freq_scale() like the arm_big_little set_target
function does. As a result the task scheduler load and utilization
signals are not frequency-invariant on this platform anymore.
Fix this by adding a call to arch_set_freq_scale() into
scpi_cpufreq_set_target().
