irq_offload: API to run a function in IRQ context Software interrupts or system calls aren't really appropriate for zephyr, but we have an ongoing need in our test code to run a function with arguments synchronously in interrupt context. This patch introduces irq_offload() which allows us to do this without separate initialization or having to manage fake IRQs in the interrupt controller. ARM assembly code contributed by Benjamin Walsh <benjamin.walsh@windriver.com> ARC is not yet implemented but will be in a subsequent patch. irq_test_common.h has been removed and all test cases updated to use the new API.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kernel: activate arch interface headers Duplicate definitions elsewhere have been removed. A couple functions which are defined by the arch interface to be non-inline, but were implemented inline by native_posix and intel64, have been moved to non-inline. Some missing conditional compilation for z_arch_irq_offload() has been fixed, as this is an optional feature. Some massaging of native_posix headers to get everything in the right scope.

kernel: sychronize irq_offload() access Entering irq_offload() on multiple CPUs can cause difficult to debug/reproduce crashes. Demote irq_offload() to non-inline (it never needed to be inline anyway) and wrap the arch call in a semaphore. Some tests which were unnecessarily killing threads have been fixed; these threads exit by themselves anyway and we won't leave the semaphore dangling. The definition of z_arch_irq_offload() moved to arch_interface.h as it only gets called by kernel C code. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
