The race condition is very unlikely on real hardware but can be observed with
qemu under heavy load.
Also add missing `memw` instructions which are generated by the C compiler but
absent in the assembly code.

Closes https://github.com/espressif/esp-idf/issues/11433
esp_execute_shared_stack_function always restored the stack watchpoint
regardless of CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK. This would lead
to an abondoned but active watchpoint on a former stack once the task
calling esp_execute_shared_stack_function is deleted, if
CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK is inactive.
This has been fixed now.

SMP FreeRTOS uses a single kernel lock for all critical sections. There is a known
issue with esp_ipc_isr_stall_other_cpu() that can cause dead if the other CPU is
already in a critical section.
This commit adds a temporary workaround to reduce the chance of deadlock by taking
the SMP FreeRTOS kernel lock first before stalling the other CPU.
See IDF-5257 for more details.

The problem with the new format is that it is hard to parse and
breaks the parser that is used by PlatformIO. The old format
is much more reasonable. I do not see how the pattern in IDFDUT.py
can work with the new format, due to the missing space after the :
The behavior of portSET_INTERRUPT_MASK_FROM_ISR() has changed in SMP FreeRTOS. It's
previous behavior is now implemented in portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS().
This commit replaces all portSET_INTERRUPT_MASK_FROM_ISR() and portCLEAR_INTERRUPT_MASK_FROM_ISR()
calls with portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS() respectively
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
Upstream xtensa exception handling will save PS, PC, and a0 registers
together when saving a minimal context. This commit ppdates the xtensa
exception handling to match upstream behavior.
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h
The following functions are deprecated:
- get_sp()
The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()
The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()
All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

components/os: Move ETS_T1_WDT_INUM, ETS_CACHEERR_INUM and ETS_DPORT_INUM to l5 interrupt
components/os: high level interrupt(5)
components/os: hli_api: meta queue: fix out of bounds access, check for overflow
components/os: hli: don't spill registers, instead save them to a separate region
Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).
Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.
components/bt: using high level interrupt in lc
components/os: Add DRAM_ATTR to avoid feature `Allow .bss segment placed in external memory`
components/bt: optimize code structure
components/os: Modify the BT assert process to adapt to coredump and HLI
components/os: Disable exception mode after saving special registers
To store some registers first, avoid stuck due to live lock after disabling exception mode
components/os: using dport instead of AHB in BT to fix live lock
components/bt: Fix hli queue send error

* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
longer signed/unsigned int).
Changes come from internal branch commit a6723fc
