Patches are on top of the -tip/master tree.
First patch in the series reverts the first version of the patch that went into
the -tip tree.

Changes from v1:
a. Split the patch into multiple patches.
b. Fix some bugs and coding style changes based on Roland's feedback.
c. Add generic PTRACE_GETREGSET/PTRACE_SETREGSET commands through which we can
   export the architecture specific regsets using the corresponding
   NT_* codes that userland is already aware of. The "xstate" regset is exported
   only using this interface.

thanks,
suresh
