arm64: mm: avoid name clash in __page_to_voff()
The arm64 __page_to_voff() macro takes a parameter called 'page', and also refers to 'struct page'. Thus, if the value passed in is not called 'page', we'll refer to the wrong struct name (which might not exist). Fixes: 3fa72fe9c614 ("arm64: mm: fix __page_to_voff definition") Acked-by: Mark Rutland <mark.rutland@arm.com> Suggested-by: Volodymyr Babchuk <Volodymyr_Babchuk@epam.com> Signed-off-by: Oleksandr Andrushchenko <Oleksandr_Andrushchenko@epam.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
