    Subject[PATCH 4.9 25/64] arm64: fix the flush_icache_range arguments in machine_kexec
    Date
    From: Christoph Hellwig <hch@lst.de>

    Commit d51c214541c5154dda3037289ee895ea3ded5ebd upstream.

    The second argument is the end "pointer", not the length.

    Fixes: d28f6df1305a ("arm64/kexec: Add core kexec support")
