I was curious, so I expanded out the kernel one. Here's the diff:

- (((addr)+((size)-1))&(~((typeof(addr))(size)-1)))
+ (((addr)+((typeof(addr))(size) - 1))&~((typeof(addr))(size)-1))

So it adds a cast, but aside from that it's the same.

[PATCH 1/5] drivers/powerpc: Replace _ALIGN_UP() by ALIGN()

2020-04-20 Thread Christophe Leroy
_ALIGN_UP() is specific to powerpc
ALIGN() is generic and does the same

Replace _ALIGN_UP() by ALIGN()
