[PATCH 1/1] powerpc: Increase COMMAND_LINE_SIZE to 2048 from 512.
From: Joseph Salisbury <hidden>

Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
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 hard 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.
