Subject: powerpc: Convert beatic_irq_mask_lock to raw_spinlock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5181e7909b28abe5ce6674412a74167fd074824a;p=linux-beck.git

powerpc: Convert beatic_irq_mask_lock to raw_spinlock

beatic_irq_mask_lock needs to be a real spinlock in RT. Convert it to
raw_spinlock.
