Keep reserved bits in CPSR on write
In patch https://sourceware.org/ml/gdb-patches/2016-04/msg00529.html
I cleared reserved bits when reading CPSR. It makes a problem that
these bits (zero) are written back to kernel through ptrace, and it
changes the state of the processor on some recent kernel, which is
unexpected.
In this patch, I keep these reserved bits when write CPSR back to
hardware.
