[PATCH 2/2] powerpc: minimizing the configuration of linkstation_defconfig
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_1. 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. Signed-off-by: Rogério Brito --- Here is the fixed patch.
