Subject: [PATCH] unexport asm/shmparam.h
Date: Sat, 14 Jul 2007 21:38:34 +0200 [thread overview]
Message-ID: <20070714193834.GA9140@aepfle.de> (raw)
SHMLBA cant possible be used in userspace, see sparc versions of that header.
Do not export asm/shmparam.h during make headers_install_all
This removes another uservisible place of PAGE_SIZE
