[makedumpfile PATCH 2/2] Fix physical-to-virtual conversion in exclude_segment()

[Petr Tesarik]

With kaslr enabled, PAGE_OFFSET may no longer be aligned to allow
calculation using bitwise OR. My fix follows the same idea as
Baoquan's commit 4c53423b995463067fbbd394e724b4d1d6ea3d62 for
set_kcore_vmcoreinfo, i.e. use arithmetic addition instead.
