Along with the  two patches given below the patch for linux_remove_breakpoint support are the prerequisites.

As suggested the response is sent over the first patch.

As the current testcase we sent is not reproducing  the issue at your end, we think the current gdb testsuite failures are the best examples to reproduce the problem.
Along with these three patches and the gdbserver patch, the gdb testsuites will provide the results expected.

Ok.

>>Thanks.  What is your testing environment?

Xilinux Petalinux Kernel is booted on a KC705 design.  gdb testsuite is using the  Linux toolchain (compiled with microblazeel-xilinx-linux-gnu(little-endian)).
