Subject: ARM: 7204/1: arch/arm/kernel/setup.c: initialize arm_dma_zone_size earlier
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9811ccdfa94b4773c8030569bd8ec75eafa485ac;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: 7204/1: arch/arm/kernel/setup.c: initialize arm_dma_zone_size earlier

arm_dma_zone_size is used by arm_bootmem_free() which is called by
paging_init(). Thus it needs to be set before calling it.
