Subject: [PATCH] ppc64: remove rma_top limit
|
||
|
|
||
|
Restricting kexec tool to allocate hole for kexec segments below 768MB
|
||
|
may not be relavent now since first memory block size can be 1024MB and
|
||
|
more.
|
||
|
|
||
|
Removing rma_top restriction will give more space to find holes for
|
||
|
kexec segments and existing in-place checks make sure that kexec segment
|
||
|
allocation doesn't cross the first memory block because every kexec segment
|
||
|
has to be within first memory block for kdump kernel to boot properly.
