Date: Wed, 15 Jul 2015 10:23:53 -0600 From: Toshi Kani <toshi.kani@...com> To: hpa@...or.com, tglx@...utronix.de, mingo@...hat.com Cc: akpm@...ux-foundation.org, bp@...en8.de, linux-mm@...ck.org, linux-kernel@...r.kernel.org, x86@...nel.org, jgross@...e.com, konrad.wilk@...cle.com, elliott@...com, Toshi Kani <toshi.kani@...com> Subject: [PATCH v2 2/4] x86, asm: Move PUD_PAGE macros to page_types.h PUD_SHIFT is defined according to a kernel configuration, which allows it be commonly used by any kernels. However, PUD_PAGE_SIZE and PUD_PAGE_MASK, which are calculated from PUD_SHIFT, are defined in page_64_types.h, which allows them be used by a 64-bit kernel only. Move PUD_PAGE_SIZE and PUD_PAGE_MASK to page_types.h so that they can be used by any kernels as well.
