Describe the bug
kernel_threads_sched_userspace cases meet out our space

To Reproduce
Steps to reproduce the behavior:
tests/kernel/sched/schedule_api

  1. mkdir build; cd build
  2. cmake -DBOARD=mimxrt1010_evk ..
  3. make
  4. See error

Expected behavior
in former build this cases are PASS,but now the code size is too large

Impact
unknown

@MaureenHelm looks like the kernel case in userspace is too large, not sure whether I need filter out those cases from rt1010?

looks like the kernel case in userspace is too large, not sure whether I need filter out those cases from rt1010?

I'd like to understand what caused the SRAM to grow from <32KB to 39KB before we consider that.

I walked this back to 2.3 and it still wouldn't fit. I think the simple fix I'll submit is to switch this platform over to using OCRAM instead of DTCM as that will give us plenty of RAM. Ultimately, it would be nice to get Zephyr to support multiple RAM blocks.

Also note that the test application has some large RAM usage because it creates 10 threads with each having their own stack defined. There are also a couple of other large chunks of RAM used.
