Xiang Xiao 8543df7e4c sched/init: Initialize the idle thread local storage by tls_init_info

Ville Juven 4c1b66246d env_dup: Fix copying of env between address environments 
If address environments are in use, it is not possible to simply
memcpy from from one process to another. The current implementation
of env_dup does precisely this and thus, it fails at once when it is
attempted between two user processes.

The solution is to use the kernel's heap as an intermediate buffer.
This is a simple, effective and common way to do a fork().

Obviously this is not needed for kernel processes.

Ville Juven 75afe491ad RISC-V: Prepare for CONFIG_BUILD_KERNEL 
- Thread context prior to system call needs to be preserved
- Allocate a kernel heap
 2022-03-18 18:20:12 +08:00
Ville Juven 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

Because idle task will call mm_malloc to create some task
and will take sem of mm. But if smp enable, the sem of mm may be
taken by other cpu, so idle may be block because take this sem and crash.

Abdelatif Guettouche 0a4982a80e Introduce ARCH_HAVE_EXTRA_HEAPS, this config is going to be used for 
chips that have multiple separate heaps.
For now it's used to enable APIs to initialize the different heaps

manage those heaps.

Masayuki Ishikawa 1a9e7efde5 smp: Remove CONFIG_SMP_IDLETHREAD_STACKSIZE 
Summary:
- The CONFIG_SMP_IDLETHREAD_STACKSIZE was introduced to optimize
  the idle stack size for other than CPU0
- However, there are no big differences between the idle stacks.
- This commit removes the config to simplify the kernel code

Impact:
- All SMP configurations

Testing:
- Tested with ostest with the following configs
- spresense:smp, spresense:rndis_smp
- esp32-devkitc:smp (QEMU), maix-bit:smp (QEMU)
- sabre-6quad:smp (QEMU), sabre-6quad:netnsh_smp (QEMU)
- raspberrypi-pico:smp, sim:smp (x86_64)
