Subject: mm/bootmem.c: replace kzalloc() by kzalloc_node()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d8bf926f8739bd35d054097907fef35d881e403;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mm/bootmem.c: replace kzalloc() by kzalloc_node()

In ___alloc_bootmem_node_nopanic(), replace kzalloc() by kzalloc_node()
in order to allocate memory within given node preferentially when slab
is available
