Michael Ellerman 466921c5a4 powerpc: Set paca->data_offset = 0 for boot cpu ... In commit 407821a we assigned a poison value to the paca->data_offset. Unfortunately with CONFIG_LOCK_STAT=y lockdep will read & write to percpu data very early in boot, prior to us initialising the percpu areas, leading to a crash. We have been getting away with this because the data_offset was previously set to zero. This causes lockdep to read & write to the initial copy of the percpu variables, which are discarded later in boot. Although that is "fishy", it does work, and for lock statistics it is no big deal to discard the counts from early boot. So set the paca->data_offset = 0 for the boot cpu paca only.
