Subject: [PATCH] x86 - hide X86_VM_MASK from userland programs v3
Date: Tue, 29 Apr 2008 22:10:11 +0400 [thread overview]
Message-ID: <20080429181011.GG6837@cvg> (raw)
X86_VM_MASK is kernel specific flags so hide it from userland programs.
It should be defined *before* ptrace.h inclusion because of circular
link between these files

David as you see we can't use existing CONFIG_VM86 for this purpose.
But that is my fault - I was to check this before cooking the patch.
