The patch titled
Extended crashkernel command line (update)
has been removed from the -mm tree. Its filename was
extended-crashkernel-command-line-update.patch
This patch was dropped because it was folded into extended-crashkernel-command-line.patch
------------------------------------------------------
Subject: Extended crashkernel command line (update)
From: Bernhard Walle <bwalle@xxxxxxx>
This is the generic part of the patch. It adds a parse_crashkernel() function
in kernel/kexec.c that is called by the architecture specific code that
actually reserves the memory. That function takes the whole command line and
looks itself for "crashkernel=" in it.
If there are multiple occurrences, then the last one is taken. The advantage
is that if you have a bootloader like lilo or elilo which allows you to append
a command line parameter but not to remove one (like in GRUB), then you can add
another crashkernel value for testing at the boot command line and this one
overwrites the command line in the configuration then.
