Ping..

Do you have any plans for these patches? The reason I'm asking is that there are
also userspace tools (namely makedumpfile and crash) which are needed for
post-mortem analysis, and they depend on kernel support. Without support in
mainline it makes little sense to port these to ARM.

As ARM is going to use LMB I know that patch 6116/1 "kdump: reserve memory for
crashkernel" needs to be changed to use LMB instead of bootmem but that change
should be quite simple.

So do you think I should rework these patches or may they be included in .36? It
would be nice to know if any changes are needed.

Thanks again,
