Subject: Regarding enable paging code and swapper_pg_dir.
Date: Sat, 2 Apr 2011 01:37:12 +0530 [thread overview]
Message-ID: <201104020137.12899.mindentropy@gmail.com> (raw)
Hi All,
In the code http://lxr.linux.no/#linux+v2.6.12/arch/i386/kernel/head.S#L186
I am not able to understand what's the reason for subtracting swapper_pg_dir
with __PAGE_OFFSET(0xc0000000). i.e. movl $swapper_pg_dir-__PAGE_OFFSET
Shouldn't it be movl $swapper_pg_dir, %eax?
Thanks.
