Subject: Re: [PATCH 4/4] x86: Replace xxx_pda() operations with x86_xx_percpu().
Date: Mon, 9 Jun 2008 11:20:44 -0700 (PDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0806091119150.30592@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <484D6A05.7010508@sgi.com>
Paravirt support is on. We have seen an issue with that in the past. Why
was that again?
Also check that there is really no use of the segment register before
start_kernel() loads it. If the segment register is used to refer to pda
stuff before start_kernel then we need to make sure that the right value
is loaded in the asm (head64.c).
