From: Fanjun Kong Date: Thu, 26 May 2022 14:20:39 +0000 (+0800) Subject: x86/mm: Use PAGE_ALIGNED(x) instead of IS_ALIGNED(x, PAGE_SIZE) X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e19d11267f0e6c8aff2d15d2dfed12365b4c9184;p=linux.git x86/mm: Use PAGE_ALIGNED(x) instead of IS_ALIGNED(x, PAGE_SIZE) The already provides the PAGE_ALIGNED() macro. Let's use this macro instead of IS_ALIGNED() and passing PAGE_SIZE directly. No change in functionality.
