Subject: [PATCH] arm64: mm: Export __flush_icache_range() to modules
lkdtm calls flush_icache_range(), which results in an out-of-line call
to __flush_icache_range(), which is not exported to modules.
Export the symbol to modules to fix this build breakage.
Fixes: 3b8c9f1cdfc5 ("arm64: IPI each CPU after invalidating the I-cache for kernel mappings")
