Subject: [PATCH] arm64: mm: use arm64_dma_phys_limit instead of
|
|
calling max_zone_dma_phys()
|
|
|
|
commit ae970dc096b2d39f65f2e18d142e3978dc9ee1c7 upstream.
|
|
|
|
By the time we call zones_sizes_init() arm64_dma_phys_limit already
|
|
contains the result of max_zone_dma_phys(). We use the variable instead
|
|
of calling the function directly to save some precious cpu time.
