fb43fd73ed signal: signal handler may cause task's state error 
For example, task is blocked by nxsem_wait(sem1), use nxsem_wait(sem2)
in signal handler, and take sem2 successfully, after exit from signal
handler to task, nxsem_wait(sem1) returns OK, but the correct result
should be -EINTR.

7549de49b4 arch/*_cpupause:Allow a spin before taking the g_cpu_wait spinlock. 
If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
cases where the next call to up_cpu_pause happens while the other CPU is
still responding to the previous resume request. In this case the
DEBUGASSERT will trigger. We should allow the first CPU to wait until the
other CPU has finished responding to the resume request.

58bdcbab9b Revert "Make: use gcc as LD" 
This reverts commit 45672c269d.

Because:

* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
  supposed to do when we use LD directly. It would be simpler to
  remove them from our LDFLAGS.

aac0db368c ARM: fix CPSR corruption after exception handling 
It seems to be caused by the corrupted or wrong CPSR restored on return
from exception. NuttX restores the context using code like this:

    msr spsr, r1

GCC translates this to:

    msr spsr_fc, r1

As a result, not all SPSR fields are updated on exception return. This
should be:

    msr spsr_fsxc, r1

This bug has been fixed by Heesub Shin in:
