Summary:
- ARCH_GLOBAL_IRQDISABLE was initially introduced for LC823450 SMP
- At that time, i.MX6 (quad Cortex-A9) did not use this config
- However, this option is now used for all CPUs which support SMP
- So it's good timing for refactoring the code
Impact:
- Should have no impact because the logic is the same for SMP
Testing:
- Tested with board: spresense:smp, spresense:wifi_smp
- Tested with qemu: esp32-core:smp, maix-bit:smp, sabre-6quad:smp
- Build only: lc823450-xgevk:rndis, sam4cmp-db:nsh

If the buffer to be flushed isn't multipled by the erase size,
let's pad the buffer proactively to avoid the allocation in ftl.

https://linux.die.net/man/2/epoll_ctl:
EPOLLONESHOT (since Linux 2.6.2)
Sets the one-shot behavior for the associated file descriptor.
This means that after an event is pulled out with epoll_wait(2)
the associated file descriptor is internally disabled and
no other events will be reported by the epoll interface.
The user must call epoll_ctl() with EPOLL_CTL_MOD to
rearm the file descriptor with a new event mask.

Linux Programmer's Manual
NAME
epoll_create, epoll_create1 - open an epoll file descriptor
...
SYNOPSIS
#include <sys/epoll.h>
int epoll_create1(int flags);
...
epoll_create1()
If flags is 0, then, other than the fact that the obsolete
size argument is dropped, epoll_create1() is the same as
epoll_create(). The following value can be included in flags
to obtain different behavior:
EPOLL_CLOEXEC
Set the close-on-exec (FD_CLOEXEC) flag on the new file
descriptor. See the description of the O_CLOEXEC flag in
open(2) for reasons why this may be useful.

DESCRIPTION
EPOLL_CTL_DEL
...
The event argument describes the object linked to the file descriptor
fd. The struct epoll_event is defined as:
typedef union epoll_data {
void *ptr;
int fd;
uint32_t u32;
uint64_t u64;
} epoll_data_t;
struct epoll_event {
uint32_t events; /* Epoll events */
epoll_data_t data; /* User data variable */
};

Provide functions which get and set the 3A (Auto white balance/Auto
exposure/Auto
focus) parameters.
These are achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS and
VIDIOC_S_EXT_CTRLS which have the following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_PARAMETER
Also, provide function which get the 3A adjustment status.
This is achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS which has the
following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_STATUS
Fix the following three bugs about ON/OFF control of auto white balance and auto
exposure:
- The returned value of VIDIOC_G_CTRL with id = V4L2_CID_AUTO_WHITE_BALANCE is
different from V4L2 specification.
- Auto exposure is locked if auto white balance lock is requested.
- Auto exposure and auto white balance are locked if auto exposure lock is
requested.

Add flags argument into sendto() and recvfrom() APIs for MSG_* flags can
handling in the daemon.
However, MSG_DONTWAIT should process in usrsock, so it unnecessary to pass to
the daemon like O_NONBLOCK.
