Ioannis Glaropoulos 6a9b3f5ddd arch: arm: allocate a wide priv stack guard for FP-capable threads
When an FP capable thread (i.e. with K_FP_REGS option)
transitions into user mode, we want to allocate a wider
MPU stack guard region, to be able to successfully detect
overflows of the privilege stack during system calls. For
that we also need to re-adjust the .priv_stack_start pointer,
which denotes the start of the writable area of the privilege
stack buffer.
