Details were discussed on quite some lists (kexec, lkml, x86, etc)
in a kernel thread with subject:
[PATCH] x86 e820: only void usable memory areas in memmap=exactmap case
The patch that memmap= can take several arguments is already queued
in linux-x86-tip in the mm2 branch.
There have been no objections on the introduction to memmap=resetusablemap
for several days after discussing things in detail. The repost patches
(will do that now) propably will show up in x86-tip mainline kernel
tree pretty soon as well.
Target for this feature to show up in Linus' tree is 3.9-rc1.
Therefore these patches check for 3.9.0 and newer kernels. If such a
kernel is tried to get loaded via kexec -p, the new memmap= syntax is used.
Please consider to apply these to the kexec-tools repository.
Thanks,
Thomas
