Subject: [AVR32] Don't use kmap() in flush_icache_page()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28c1d39db83357bad55e3482fe09386429728ded;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[AVR32] Don't use kmap() in flush_icache_page()

flush_icache_page() can be called from atomic context, so we can't
use kmap(). Use page_address() instead.
