Subject: [PATCH] mips: setup_zero_pages count 1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=68352e6ee3675e23b492c51908951058de4f6fe0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] mips: setup_zero_pages count 1

Page count should be initialized to 1 on each of the MIPS empty zero pages,
to avoid a bad_page warning whenever one of them is freed from all mappings.
