Message-ID: <20090428133200.GB12828@ime.usp.br> Date: Tue, 28 Apr 2009 10:32:00 -0300 From: Rogério Brito <rbrito@....usp.br> To: Kumar Gala <galak@...nel.crashing.org> Cc: Guennadi Liakhovetski <g.liakhovetski@....de>, linux-mtd@...ts.infradead.org, linux-kernel@...r.kernel.org, linuxppc-dev@...abs.org Subject: [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_BLK_DEV_RAM. 05. disable CONFIG_SCSI_LOWLEVEL, as no device under that tree is used. 06. idem for CONFIG_NETDEV_10000. 07. idem for CONFIG_WIRELESS. 08. idem for CONFIG_HWMON. 09. idem for CONFIG_CRYPTO_HW. 10. disable CONFIG_VIDEO_OUTPUT_CONTROL. 11. keep consistency and disable extended attributes in CIFS, ext3, and NFS. 12. enable CONFIG_PRINTK_TIME.
