0476e30a6d mm/kmm_map: Add support to dynamically map pages into kernel virtual memory
This adds functionality to map pages dynamically into kernel virtual
memory. This allows implementing I/O remap for example, which is a useful
(future) feature.

Now, the first target is to support mapping user pages for the kernel.

Why? There are some userspace structures that might be needed when the
userspace process is not running. Semaphores are one such example. Signals
and the WDT timeout both need access to the user semaphore to work
properly. Even though for this only obtaining the kernel addressable
page pool virtual address is needed, for completeness a procedure is
provided to map several pages.

f7cfcd4e95 sched: add the CPU bitset to initialize the non-exclusive CPU
Set the Default CPU bits. The way to use the unset CPU is to call the
sched_setaffinity function to bind a task to the CPU. bit0 means CPU0.

a23b30d625 sched: Remove volatile from the task list

75afe491ad RISC-V: Prepare for CONFIG_BUILD_KERNEL
- Thread context prior to system call needs to be preserved

50578dc501 Fix the initial idle tasks environment
- User mode allocator was used for setting up the environment. This
  works in flat mode and probably in protected mode as well, as there
  is always a a single user allocator present
- This does not work in kernel mode, where each user task has its own
  heap allocator. Also, when the idle tasks environment is being set,
  no allocator is ready and the system crashes at once.

Fix this by using the group allocators instead:
- Idle task is a kernel task, so its group is privileged
- Add group_realloc
- Use the group_malloc/realloc functions instead of kumm_malloc
