Subject: [PATCH v3 2/10] x86/asm: Move PUD_PAGE macros to page_types.h
Date: Wed, 5 Aug 2015 15:43:25 -0600 [thread overview]
Message-ID: <1438811013-30983-3-git-send-email-toshi.kani@hp.com> (raw)
In-Reply-To: <1438811013-30983-1-git-send-email-toshi.kani@hp.com>
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.
