-Subject: Fix GDB watchpoints on Cell
-From: Arnd Bergmann <arnd@arndb.de>
-References: 456405 - LTC50396
-
-An earlier patch from Jens Osterkamp attempted to fix GDB
-watchpoints by enabling the DABRX register at boot time.
-Unfortunately, this did not work on SMP setups, where
-secondary CPUs were still using the power-on DABRX value.
-
-This introduces the same change for secondary CPUs on cell
-as well.
