If dynamic interrupts are enabled, a set of trampoline stubs
are generated which transfer control to a common dynamic
interrupt handler function, which then looks up the proper
handler and parameter and then executes the interrupt.
Based on the prior x86 dynamic interrupt implementation which
was removed from the kernel some time ago, and adapted to
changes in the common interrupt handling code, build system,
and IDT generation tools.
An alternative approach could be to read the currently executing
vector out of the APIC, but this is a much slower operation.

In the past the capability to install interrupts at runtime was
removed due to lack of use-cases for Zephyr's intended targets.
Now we want to support hypervisor applications like ACRN where
virtual devices are presented to the kernel using PCI enumeration,
and the interrupt configuration is not known at build time.

This commit contributes a patch to the Arm Cortex-M linker
script, which guarantees that the linker sections for shared
memory and the application memory will have sufficient padding
in between, so that the latter will start from an address that
is 32-byte aligned. This is required for ensuring that the MPU
regions defined using the start and end addresses of the two
sections will not overlap. The patch targets ARMv8-M MPU with
no requirement for power-of-two alignment and size.

Tty device gets only read/write calls, but console retains
getchar/putchar for convenience.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Previously, transmit was effectively non-blocking - a character either
went into buffer, or -1 was returned. Now it's possible to block if
buffer is full. Timeout is K_FOREVER by default, can be adjusted
with tty_set_tx_timeout() (similar to receive timeout).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
This allows to specify receive timeout, instead of previously
hardcoded K_FOREVER value. K_FOREVER is still the default, and can
be changes after tty initialization using tty_set_rx_timeout() call,
and timeout is stored as a property of tty. (Instead of e.g. being
a param of each receive call. Handling like that is required for
POSIX-like behavior of tty).

All the handling of POSIX file descriptors is now done by fdtable.c.
fs.c still manages its own table of file structures of the underlying
fs lib.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
The table allows to wrap read/write (i.e. POSIX-compatible) semantics
of any I/O object in POSIX-compatible fd (file descriptor) handling.
Intended I/O objects include files, sockets, special devices, etc.
The table table itself consists of (underlying obj*, function table*)
pairs, where function table provides entries for read(), write, and
generalized ioctl(), where generalized ioctl handles all other
operations, up to and including closing of the underlying I/O object.

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.

BITS_PER_LONG is computed as the multiplication of predefined

CoAP library is migrated to support over socket based
applications or other higher layer protocols. Most of the
API's and functionality is kept as it is except few changes.
net_pkt/net_buf is removed from CoAP library. Now it expects
a pre-allocated flat buffer and length. If there is not enough
space to append any data, library simply returns an error.
It's user's responsibility to allocate and free memory.

used to clear the memory, but now it's user's responsibility
to free the memory.
