Subject: [PATCH 2/2] powerpc: minimizing the configuration of linkstation_defconfig

From: Rogério Brito <[email-masked]>
Date: Tue, 28 Apr 2009 13:44:16 -0300

This patch addresses the following issues:

01. makes CFQ the default scheduler, to be in line with the rest of  
the kernel.

02. since linkstations are meant to store files, enable large blk  
devices.

03. disable CONFIG_MIGRATION in in such low memory devices.

04. disable CONFIG_SCSI_LOWLEVEL, as no device under that tree is  
used.

05. idem for CONFIG_NETDEV_10000.

06. idem for CONFIG_WIRELESS.

07. idem for CONFIG_HWMON.

08. idem for CONFIG_CRYPTO_HW.

09. disable CONFIG_VIDEO_OUTPUT_CONTROL.

10. keep consistency and disable extended attributes in CIFS, ext3,  
and NFS.

11. enable CONFIG_PRINTK_TIME.
