nice doing. Just an ordering comment, for the upstream inclusion, it
seems that what we need is two patches
1. fix for some issues e.g around ints/longs and friends which is
likely to be the source of the bug which once fixed eliminated the
crashes you hit in the 28-30/31 range
2. the vmalloc etc patch you posted here
This way you avoid reverting some code from patch #2 in patch #1 - it
helps with maintainance
Or.
I prefer that first patch will hold the limit of 28 as part of -
otherwise system with large memory may fail to load,and the vmalloc fix
won't help.
Second patch fixes the limit and enables mapping of 8TB.
Second patch was already sent.
