The patch titled
ia64: fix parsing kernelcore boot option
has been removed from the -mm tree. Its filename was
ia64-specify-amount-of-kernel-memory-at-boot-time-fix.patch
This patch was dropped because it had testing failures
------------------------------------------------------
Subject: ia64: fix parsing kernelcore boot option
From: Yasunori Goto <y-goto@xxxxxxxxxxxxxx>
cmdline_parse_kernelcore() should return the next pointer of boot option
like memparse() doing. If not, it is cause of eternal loop on ia64 box.
