Currently, numa & prom are the only users of drmem LMB walk code. Loading kdump with kexec_file also needs to walk the drmem LMBs to setup the usable memory ranges for kdump kernel. But there are couple of issues in using the code as is. One, walk_drmem_lmb() code is built into the .init section currently, while kexec_file needs it later. Two, there is no scope to pass data to the callback function for processing and/or erroring out on certain conditions. Fix that by, moving drmem LMB walk code out of .init section, adding scope to pass data to the callback function and bailing out when an error is encountered in the callback function.
