Hi All,
	Please find a revised patchset that implement hardware breakpoint
interfaces for PPC64 architecture. The changes over the previous patchset
posted here: http://ozlabs.org/pipermail/linuxppc-dev/2009-May/071942.html
are given below.

Kindly let me know your comments about the same.

Changelog - ver II
------------------
(Ver I: http://ozlabs.org/pipermail/linuxppc-dev/2009-May/071942.html)

- Split the monolithic patch into six logical patches

- Changed the signature of arch_check_va_in_<user><kernel>space functions. They
  are now marked static.

- HB_NUM is now called as HBP_NUM (to preserve a consistent short-name
  convention)

- Introduced hw_breakpoint_disable() and changes to kexec code to disable
  breakpoints before a reboot.
  
- Minor changes in ptrace code to use macro-defined constants instead of
  numbers.

- Introduced a new constant definition INSTRUCTION_LEN in reg.h

Thanks,
K.Prasad
