#     selftests/powerpc/dexcr: Add DEXCR status utility lsdexcr
#     
#     Add a utility 'lsdexcr' to print the current DEXCR status. Useful for
#     quickly checking the status such as when debugging test failures or
#     verifying the new default DEXCR does what you want (for userspace at
#     least). Example output:
#     
#         # ./lsdexcr
#            uDEXCR: 04000000 (NPHIE)
#            HDEXCR: 00000000
#         Effective: 04000000 (NPHIE)
#     
#                 SBHE   (0): clear   (Speculative branch hint enable)
#               IBRTPD   (3): clear   (Indirect branch recurrent target ...)
#                SRAPD   (4): clear   (Subroutine return address ...)
#                NPHIE * (5): set     (Non-privileged hash instruction enable)
#                 PHIE   (6): clear   (Privileged hash instruction enable)
#     
#         DEXCR[NPHIE] enabled: hashst/hashchk working
