That and mostly the fact that `sanity_check_segment_list()` explicitely rejects
any segment that either does not start or end on a page boundary:
int sanity_check_segment_list(struct kimage *image)
{
// ...
for (i = 0; i < nr_segments; i++) {
unsigned long mstart, mend;
mstart = image->segment[i].mem;
mend = mstart + image->segment[i].memsz;
if (mstart > mend)
return -EADDRNOTAVAIL;
if ((mstart & ~PAGE_MASK) || (mend & ~PAGE_MASK))
return -EADDRNOTAVAIL;
if (mend >= KEXEC_DESTINATION_MEMORY_LIMIT)
return -EADDRNOTAVAIL;
}
// ...
}

Does it warrant a second revision to change the log?
Thanks,
