[PATCH] x86: _edata should include all .data.* sections on X86_64

[Catalin Marinas <catalin.marinas@arm.com>]

The .data.read_mostly and .data.cacheline_aligned sections aren't
covered by the _sdata .. _edata range on X86_64. This affects the
kmemleak reporting leading to possible false positives by not scanning
all the whole data section.
