Circular buffer does not use DMA linked list therefore function
sam_freelinklist() cannot be called as it would fail on assertion (csa
not defined). Peripheral that calls DMA should care of buffer invalidation
instead.

EALREADY:
Both Linux(asm-generic/errno.h) and FreeBSD(sys/sys/errno.h) regard it as "Operation already in progress"
ESTALE:
Linux specifically removed the "NFS" description, and we may not only use it for NFS
0ca4343518
The ECANCELED and EOWNERDEAD also use different strings from Linux's header, but their meanings are same, and NuttX's description are more likely to obey POSIX 1003.1-2008, so not changing them.

1. the lio_sigsetup() method use a universal sighand instance across all
aiocb instances, but inside the lio_sighandler() method, if one aiocb is
handle finished, then this method will free the sighand instance that
come along with current aiocb instance. thus when handle next aiocb
instance, use-after-free crash will happen. in order to solve this
problem, we make each aiocb instance have their own sighand instance
2. make the lio_listio implementation can pass the
ltp/open_posix_testsuite/lio_listio testcases
3. the modification are referred to https://pubs.opengroup.org/onlinepubs/9699919799/functions/lio_listio.html

Port based on arch/arm/nrf53.
Modem not fully supported yet. At the moment, initialization and AT interface work.
Sockets and GNSS interface will be added later.
There is no need to use global spinlock to protect netdev
specific data counters. Allocate per-netdev specific spinlock
to get better locking granularity.
Move C/C++ atomic support checking to compiler.h

RISC-V ISA updates
Compared to previous releases, starting from 12.x, the compiler implements the new RISC-V ISA, which introduces an incompatibility issue, and builds might throw error messages like unrecognized opcode csrr.
The reason is that csr read/write (csrr*/csrw*) instructions and fence.i instruction were separated from the I extension, becoming two standalone extensions: Zicsr and Zifencei.
The solution is to add _zicsr and/or _zifencei to the -march option, e.g. -march=rv32imac becomes -march=rv32imac_zicsr_zifencei.
Summary:
- Some network drivers such as GS2200M do not support to bind
a local port for TCP client socket. In this case, this config
disables to bind the port.
- See also https://github.com/apache/nuttx/pull/3707
Impact:
- None
Testing:
- Tested with spresense:wifi_smp (Kconfig will be updated later)
- Tested with sabre-6quad:netnsh_smp (QEMU)

Summary:
- During testing with qemu + kvm, I noticed that nuttx hangs
when setting cntfrq_el0. With qemu + kvm, it starts from
EL1 because we can not specify virtualization=on
- However, I noticed that it works without setting cntfrq_el0
- This commit fixes this issue
Impact:
- None
Testing:
- Tested with qemu-7.1 (both with kvm and without kvm)
- NOTE: to work with kvm, GICv2 must be used.

Changes the executable type built against the `make export` target fully linked by default. This greatly improves performance when loading applications, as relocations no longer need to be processed.
