Subject: [PATCH] remove availability for PAGE_SIZE and friends (i386)
Date: Tue, 6 Mar 2007 08:31:45 -0800	[thread overview]
Message-ID: <9c21eeae0703060831k1a99bd13k1bf81afaabb6f1af@mail.gmail.com> (raw)

After a bit of discussion I found out that PAGE_SIZE really shouldn't
be available for use at all by userspace. So here's a patch to move
the __KERNEL__ define to include PAGE_SIZE and friends for i386.

Thanks,
- David Brown
