Geert Uytterhoeven ca052f7924 [POWERPC] PS3: Save power in busy loops on halt
PS3 save power on halt:
  - Replace infinite busy loops by smarter loops calling
    lv1_pause() to save power.
  - Add ps3_halt() and ps3_sys_manager_halt().
  - Add __noreturn annotations.

Geoff Levand 75ffe88d2b [POWERPC] PS3: Use system reboot on restart
The PS3 Other OS boot flag is not checked when an LPAR reboot is done,
so the ps3-boot-game-os utility fails to reboot the system into the
Game OS.  This fix changes the PS3 restart handler from requesting an
PS3_SM_NEXT_OP_LPAR_REBOOT to requesting an PS3_SM_NEXT_OP_SYS_REBOOT.

Takashi Yamamoto a7faa8dc95 [POWERPC] PS3: Fix setting bookmark in logical performance monitor
Fix the ps3_set_bookmark() routine of the PS3 logical performance
monitor driver.

To properly set a performance monitor bookmark the Cell processor
requires no instruction branches near the setting of the bookmark
SPR.  Testing showed that the use of the db10cyc instruction did
not work correctly.  This change replaces the db10cyc instruction
with 10 nop instructions.
