Because these two functions are called from threads and ISR.
And they run a bit-wise OR operation on the interrupt registers.
So protect them to prevent race condition between thread and ISR
context where causing an interrupt won't enable as expected.
eg.
- Pseudo code of thread enable IER1's bit1:
1. load word from IER1 (0x40) and write into CPU register S1
=> S1=0x40
2. Or S1's bit1
=> S1=0x42
(But if an interrupt is triggered here)
3. Store word to IER1 from S1
=> IER1=0x42
(IER1 will be 0x42 not 0x43, IER1's bit0 is disable again due to the
race condition above)
-Pseudo code of ISR enable IER1's bit0
1. load word from IER1 (0x40) write into CPU register S2
=> S2=0x40
2. Or S2's bit0
=> S2=0x41
3. Store word to IER1 from S2
=> IER1=0x41
4. Go back to thread.

So far the maximum configurable file size was limited to 16KB (2^14).
This might be enough for small partitions on internal flash. For
external QSPI memories however, this is certainly too restrictive.
Change maximum configurable file size to be 1GB, which is 2^30. Such
value will prevent signed integers overflow on 32-bit platforms, while
giving user full flexibility on how big log files should be.

rand() and srand() are pseudo-random number generator functions
defined in ISO C. This implementation uses the Linear Congruential
Generator (LCG) algorithm with the following parameters, which are the
same as used in GNU Libc "TYPE_0" algorithm.
Modulus 2^31
Multiplier 1103515245
Increment 12345
Output Bits 30..0
Note that the default algorithm used by GNU Libc is not TYPE_0, and
TYPE_0 should be selected first by an initstate() call as shown below.
All global variables in a C library must be routed to a memory
partition in order to be used by user-mode applications when
CONFIG_USERSPACE is enabled. Thus, srand_seed is marked as
such. z_libc_partition is originally used by the Newlib C library but
it's generic enough to be used by either the minimal libc or the
newlib.
All other functions in the Minimal C library, however, don't require
global variables/states. Unconditionally using z_libc_partition with
the minimal libc might be a problem for applications utilizing many
custom memory partitions on platforms with a limited number of MPU
regions (eg. Cortex M0/M3). This commit introduces a kconfig option
CONFIG_MINIMAL_LIBC_RAND so that applications can enable the
functions if needed. The option is disabled by default.
Because this commit _does_ implement rand() and srand(), our coding
guideline check on GitHub Action finds it as a violation.
Error: lib/libc/minimal/include/stdlib.h:45:WARNING: Violation to
rule 21.2 (Should not used a reserved identifier) - srand
But this is false positive.
The following is a simple test program for LCG with GNU Libc.
#include <stdio.h>
#include <stdlib.h>
int main()
{
static char state[8];
/* Switch GLIBC to use LCG/TYPE_0 generator type. */
initstate(0, state, sizeof(state));
srand(1); /* Or any other value. */
printf("%d\n", rand());
printf("%d\n", rand());
return 0;
}
See initstate(3p) for more detail about how to use LCG in GLIBC.

Zephyr Bluetooth Low Energy Controller for mesh stack
uses pre-emptible continuous scanning, allowing advertising
events to be transmitted without delay when advertising is
enabled. No need to compensate with scan window duration.
Zephyr Bluetooth Low Energy Controller built for nRF51x
SoCs use CONFIG_BT_CTLR_LOW_LAT=y, and continuous scanning
cannot be pre-empted, hence, scanning will block advertising
events from being transmitted. Increase the advertising
duration by the amount of scan window duration to compensate
for the blocked advertising events.

Some devices compatibles with the WS2812 IC have a different reset/latch
delay.
This patch introduces the "reset-delay" optional property for the WS2812
DT binding and adds support to the ws2812_spi driver. This new property
allows to configure the reset/latch delay of a WS2812 compatible LED
strip controller from its DT node.
If omitted the driver uses 8 microseconds by default (which is good for
the WS2812 IC).

Some devices compatibles with the WS2812 IC have a different channel to

mapping of a WS2812 compatible LED strip controller from its DT node.
Since this property also allows to know if a white channel is available,
then this patch removes the "has-white-channel" property.

When DMA switches from one buffer to another ENDRX followed by
RXSTARTED is generated. Code flow assumes that ENDRX will be
handled before RXSTARTED but this may not be the case if there
is a short between ENDRX and RXSTARTED and event occurs after
ENDRX event check but before RXSTARTED event check. In that case,
RXSTARTED event is handled first. Such case may happen if there
is a higher priority interrupt that may preempt UARTE interrupt
handler.
