Subject: s390: get rid of superfluous __GFP_REPEAT
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10d58bf297e2cba0cfa2cd143d4f0df26e129040;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

s390: get rid of superfluous __GFP_REPEAT

__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.

page_table_alloc then uses the flag for a single page allocation.  This
means that this flag has never been actually useful here because it has
always been used only for PAGE_ALLOC_COSTLY requests.
