In this nested loop, the iteration variable is the same for both loops.
This is a typo and the inner loop should use a new loop variable.

Memory pointed by priv may be used (in line 1289) after it is
freed in line 1283.
Fix by adding the missing return statement in error handling.

It is used to write the log message to the channel immediately
when the log message is generated in the interrupt context, which
is faster than the normal force callback.

syslog_force is used to force the syslog output to the
console in interrupt context, but we can use syslog_write
to do the same(and more) thing.

This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size
Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

If sendfile() is called with a zero count, it will nevertheless
try to send the data. This is mostly meaningless, it causes
waste of resources, and in some cases delays.
This commit adds special handling for this case, allowing
sendfile to return immediately zero. The new behavior is
in line with the Linux variant of sendfile.
When asserting, automatically analyze whether
there is a deadlock in the thread, and if there
is a deadlock, print out the deadlocked thread.
The principle is to analyze whether there is
a lock ring through the tcb holder.

Summary:
- In this implementation, only one descriptor is used for RX.
- NOTE: we still use two descriptors for TX
Impact:
- None

SAMv7 encoder driver with GPIO pins was written without IOCTL support.
While this driver does not require any lower level IOCTLs for its
functionality the upper layer fails on assertion when unknown command
can not be send to lower layer. This commit adds IOCTL handler that
always returns -ENOTTY as no commands are supported.

- Save the FPU registers into the tcb so they don't get lost if the stack
frame for xcp.regs moves (as it does)
- Handle interger and FPU register save/load separately
- Integer registers are saved/loaded always, like before
- FPU registers are only saved during a context switch:
- Save ONLY if FPU is dirty
- Restore always if FPU has been used (not in FSTATE_OFF, FSTATE_INIT)
- Remove all lazy-FPU related logic from the macros, it is not needed
Why? The tcb can contain info that is needed by the context switch
routine. One example is lazy-FPU handling; the integer registers can
be stored into the stack, because they are always stored & restored.
Lazy-FPU however needs a non-volatile location to store the FPU registers
as the save feature will skip saving a clean FPU, but the restore must
always restore the FPU registers if the thread uses FPU.
This adds support for the CoreMMC v3.1 FPGA driver as described
in Microchip Handbook HB0510. The driver doesn't support DMA.
