Date: Mon, 14 Apr 2014 11:30:33 -0400 From: Joseph Salisbury <joseph.salisbury@...onical.com> To: linux-kernel@...r.kernel.org, benh@...nel.crashing.org, paulus@...ba.org Cc: linuxppc-dev@...ts.ozlabs.org, stable@...r.kernel.org Subject: [PATCH 1/1] powerpc: Increase COMMAND_LINE_SIZE to 2048 from 512. 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.
