Summary:
- In case of BUILD_KERNEL, NuttX uses USR mode sp and SVC mode sp.
- The kernel runs on SVC mode sp.
- While the kernel is running, up_getsp() cannot get the TLS address.
- The kernel requires tls_get_info() function.
- For the user land, up_getsp() can be used.
- tls_getinfo.c is always compiled and tls_get_info() function is
filtered by macros in the tls_getinfo.c.
Impact:
BUILD_KERNEL
Testing:
test program on custom Cortex-A9 board (BUILD_KERNEL)
ostest on sabre-6quad:smp (QEMU, BUILD_FLAT)

usage:
echo <pid/used/free> trace > /proc/memdump
echo used > /proc/memdump //output all used memory info with backtrace
echo free > /proc/memdump //output all free memory info
echo 22 > /proc/memdump //output used memory info for task pid is 22 with backtrace

Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.

For up_irq_disable, use XCHAL_EXCM_LEVEL
For up_irq_save, use XCHAL_IRQ_LEVEL.
Then we can use svcall in enter_crritical_section.

In some scenarios, We need to update state information internally.
Instead of use idle-task to drive the checkstate and change state
function.
