Change the code to use an unpatched variant of cache maintenance - Remove unnecessary ISBs from set_{pte,pmd,pud} - perf: xgene_pmu: Fix IOB SLOW PMU parser error * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Remove unnecessary ISBs from set_{pte,pmd,pud} arm64: Avoid flush_icache_range() in alternatives patching code drivers/perf: xgene_pmu: Fix IOB SLOW PMU parser error
