In smp when cpu0 calls up_cpu_resume to release the cpu1 lock, another locked cpu1 did not execute immediately,
and soon cpu0 called up_cpu_resume again, now cpu1 unable to respond to the interrupt at this time, resulting in a deadlock.
Our solution is to restore cpu1 execution from asynchronous to synchronous to ensure that cpu1 is restored.

Fix:
```
mksymtab.c: In function ‘main’:
mksymtab.c:280:15: warning: the comparison will always evaluate as ‘true’ for the address of ‘g_parm’ will never be NULL [-Waddress]
280 | cond = (g_parm[COND_INDEX] && strlen(g_parm[COND_INDEX]) > 0);

We don't want to get a NULL pointer after iob_pack on an IOB chain with
several iobs with length 0, it should return one IOB with length 0.
Otherwise each place calls iob_pack needs to check the result.

We have a case that an http server gives out-of-ordered ACKs, and NuttX client makes `ofoseg`s with length 0, trying to rebuild / put them into `ofosegs` array, which is not intended (no available data and should be skipped). This breaks later logic and finally crashed in `tcp_ofoseg_bufsize` (`ofosegs[i].data` is `NULL`, which should never happen in normal logic).
Note:
- `iob_trimhead` won't return `NULL` when it's applying on normal IOB.
- Keep `dev->d_iob == NULL` to avoid `iob_trimhead` changed.
- `iob_free_chain` will do nothing when applied to `NULL`.

* Bind smartfs0 to LUN 0 instead of mmcsd0
* Use USB composite code from similar boards
* Pull in CDC/ACM code as well
boards/stm32f411-minimum: composite: style refactor
* Unalign `int strbase = ` text, use single spaces
* Rename `int n` to `int dev_idx` like in newer `_composite.c` board code
* Add composite defconfig with CDC/ACM and MSC for build-testing
* OTG_FS_VBUS, OTG_FS_ID conflict with USART1. These are not
connected to USB-C in any WeAct Studio MiniF4 board revisions.
* PC9 PWRON & PD5 OVER do not exist on UFQFPN48.
Summary:
To reduce the count of FPU context switching will result at a
performance improve with system. it need to balance between
the using of FPU and counts of FPU trap
the PR submit a base method to see performance counts for
the FPU with NuttX procfs
Please read README.txt at chapter of FPU Support and Performance

was updated to be able to check pipes and named pipes behavior.
