2018-07-10	kern/panic: remove initialization operation	Richard Braun
	Maintaining correct dependencies for the panic function is too complicated. It may be used very early, but would depend on the console, which is normally available quite late during initialization. Instead, the behavior of panic is now "best effort", i.e. if called at a time where it works, good, otherwise, the behavior is undefined, but should result in a freeze or a reset most of the time.
2018-02-24	New errno.h standard header	Richard Braun
	Use standard errno codes. This change also adds strerror to string.h.
2018-02-20	Rework the initialization operations of some kernel modules	Richard Braun
	In order to avoid workarounds that check whether a module is ready or not, break the initialization of some core modules into a bootstrap step for basic BSP initialization, and a setup step that completes initialization. Most users only need the bootstrap operation as a dependency, especially since scheduling isn't enabled yet.
2017-10-04	Fix some header inclusions	Richard Braun

2017-09-21	Merge branch 'xbuild'	Richard Braun

2017-09-21	New build system	Richard Braun
	The new build system, called xbuild, is a minimalistic kbuild-like make-based build system, also using kconfig for scalable configurations.
2017-09-20	kern/work: fix work_setup dependencies	Richard Braun

2017-09-06	Use new thread_check_intr_context function consistently	Richard Braun

2017-09-02	kern/thread: new preemption control macros	Richard Braun
	These new macros take care of disabling/restoring interrupts in the appropriate order.
2017-08-06	Fix dependencies on percpu_setup	Richard Braun

2017-07-13	Switch to initialization operations	Richard Braun

2017-06-25	Use the C11 alignas and noreturn macros	Richard Braun

2017-06-24	Move the CPU_L1_SIZE macro to x86/cpu module	Richard Braun

2017-06-10	Use log functions where appropriate	Richard Braun

2017-06-09	kern/work: fix manager wakeup	Richard Braun
	Commit 1b902346ce502870329bda19d92d317a21cab56e introduced a minor regression by also removing a check on the manager of a work pool, which is a pointer to a work_thread, and not directly a thread structure.
2017-06-03	kern/thread: improve thread_wakeup robustness	Richard Braun

2017-05-30	Move assert.h to the include directory	Richard Braun
	This turns assert.h into a standard header.
2017-04-29	New stdio.h standard header	Richard Braun
	Make kernel code obtain definitions for the printf family of functions through the inclusion of the standard stdio.h header.
2017-04-29	kern/printk: rename to printf	Richard Braun
	The printk functions are close enough to the printf ones to bear the same names.
2017-03-16	Update system counter names	Richard Braun
	Now that event counters have been replaced with system counters, drop the convention of naming the counter as the event it tracks.
2017-03-15	kern/work: move work_pool_init and work_setup to the .init section	Richard Braun

2017-03-15	kern/syscnt: replace the evcnt module	Richard Braun
	The syscnt module supports more generic counters, in addition to atomic access from any context on any architecture.
2017-03-14	Use the X15 namespace consistently for macros defined by autoconf	Richard Braun

2017-02-08	kern/thread: add wait channels	Richard Braun

2017-02-04	Clean up compilation	Richard Braun
	Instead of mixing standard headers and internal redefinitions of standard types, completely rely on the compiler for what is guaranteed for a free standing environment. This results in the removal of kern/stddef.h and kern/stdint.h. The kern/types.h header is reintroduced for the different (and saner) purpose of defining types not specified in standard C, namely ssize_t for now.
2017-01-29	kern/thread: rename "time-sharing" to "fair-scheduling"	Richard Braun

2017-01-24	kern/thread: add the THREAD_KERNEL_PREFIX macro	Richard Braun
	This macro is used to build kernel thread names.
2016-12-09	Force brackets around one-line conditional statements	Richard Braun
	This change was done using astyle, with a few manual editing here and there.
2014-12-10	kern/work: update call to kmem_cache_init	Richard Braun

2014-09-05	kern/work: use percpu variables	Richard Braun

2014-06-19	kern/work: synchronously destroy worker threads	Richard Braun

2014-06-18	Set threads as detached where applicable	Richard Braun

2014-06-18	kern/work: improve per-processor pools synchronization	Richard Braun
	Rely on disabling preemption only instead of a spin lock when accessing per-processor pools.
2014-06-17	kern/work: don't name work pools	Richard Braun

2014-06-17	kern/work: per-processor work pools	Richard Braun

2014-06-07	kern/work: add a comment back	Richard Braun
	That comment contains a TODO item that was removed by mistake.
2014-05-24	kern/work: rework worker id allocation	Richard Braun
	Replace the radix tree with a bitmap and adjust ID allocation. The use of a radix tree was overkill for this, and initially intended only as an example of how to use the data structure in the kernel.
2014-04-26	kern/work: use thread creation attributes accessors	Richard Braun

2014-01-02	Declare variables as read mostly where appropriate	Richard Braun

2013-07-05	kern/work: update rdxtree calls for 64-bit keys	Richard Braun

2013-06-10	kern/work: fix radix tree usage	Richard Braun
	Radix tree operations must be done with preemption enabled since they might allocate memory. Use a separate mutex to synchronize access to the tree.
2013-06-09	kern/work: use a radix tree for worker ID allocation	Richard Braun

2013-06-03	kern/work: new module	Richard Braun
	This module implements thread pools to concurrently process queues of deferred works.
