CONFIG_HAVE_MIXED_BREAKPOINTS_REGS (not configurable)

configname: CONFIG_HAVE_MIXED_BREAKPOINTS_REGS

Linux Kernel Configuration
└─>HAVE_MIXED_BREAKPOINTS_REGS
In linux kernel since version 2.6.35 (release Date: 2010-08-01)  
Depending on the arch implementation of hardware breakpoints,
some of them have separate registers for data and instruction
breakpoints addresses, others have mixed registers to store
them but define the access type in a control register.
Select this option if your arch implements breakpoints under the
latter fashion.
