So we should use this size to align the member of paca_struct. This only change the paca_struct's members which are private to book3e CPUs, and should not have any effect to book3s ones. With this, we save 192 bytes. Also change it to __aligned(size) since it is preferred over __attribute__((aligned(size))). Before: /* size: 1920, cachelines: 30, members: 46 */ /* sum members: 1667, holes: 6, sum holes: 141 */ /* padding: 112 */ After: /* size: 1728, cachelines: 27, members: 46 */ /* sum members: 1667, holes: 4, sum holes: 13 */ /* padding: 48 */ Signed-off-by: Kevin Hao Signed-off-by: Scott Wood --- Reading git-diff-tree failed
