Subject: [PATCH 3/3][RFC][v1] powerpc: kconfig: Increase the size of COMMAND_LINE_SIZE to 2048 from 512 for powerpc.

BugLink: http://bugs.launchpad.net/bugs/1306677

While booting the PPC64EL kernel, the command line gets truncated to 512 characters. This is due to a limit of 512 defined for COMMAND_LINE_SIZE.  It would be beneficial to have a command line longer than 512 characters, as iscsi targets and cloud-init parameters are passed through the kernel command line.

         This is the per architecture maximum command line size.
