Subject: [PATCH 3/4] x86_64: Fold pda into per cpu area
Date: Tue, 03 Jun 2008 17:30:21 -0700	[thread overview]
Message-ID: <20080604003019.509483000@polaris-admin.engr.sgi.com> (raw)
In-Reply-To: <20080604003018.538497000@polaris-admin.engr.sgi.com>

[-- Attachment #1: zero_based_fold --]
[-- Type: text/plain, Size: 16555 bytes --]

  * Declare the pda as a per cpu variable.

  * Make the x86_64 per cpu area start at zero.

  * Since the pda is now the first element of the per_cpu area, cpu_pda()
    is no longer needed and per_cpu() can be used instead.  This also makes
    the _cpu_pda[] table obsolete.

  * Since %gs is pointing to the pda, it will then also point to the per cpu
    variables and can be accessed thusly:

	%gs:[&per_cpu_xxxx - __per_cpu_start]
