This patchset fixes memory_hotplug_max() routine to return correct
value of maximum hotpluggable address.
In this version, whitespace fixes are separated into a different patch.

memory_hotplug_max() uses hot_add_drconf_memory_max() to get maxmimum
addressable memory by referring to ibm,dyanamic-memory property. There
are three problems with the current approach:
1 hot_add_drconf_memory_max() assumes that ibm,dynamic-memory includes
all the LMBs of the guest, but that is not true for PowerKVM which
populates only DR LMBs (LMBs that can be hotplugged/removed) in that
property.
2 hot_add_drconf_memory_max() multiplies lmb-size with lmb-count to arrive
at the max possible address. Since ibm,dynamic-memory doesn't include
RMA LMBs, the address thus obtained will be less than the actual max
address. For example, if max possible memory size is 32G, with lmb-size
of 256MB there can be 127 LMBs in ibm,dynamic-memory (1 LMB for RMA
which won't be present here). hot_add_drconf_memory_max() would then
return the max addressable memory as 127 * 256MB = 31.75GB, the max
address should have been 32G which is what ibm,lrdr-capacity shows.
3 In PowerKVM, there can be a gap between the end of boot time RAM and
beginning of hotplug RAM area. So just multiplying lmb-count with
lmb-size will not provide the correct max possible address for PowerKVM.
This patch fixes 1 by using ibm,lrdr-capacity property to return the max
addressable memory whenever the property is present. Then it fixes 2 & 3
by fetching the address of the last LMB in ibm,dynamic-memory property.

No that's fine, it still applies cleanly.
Have you tested this on PowerVM ?
Has this always been broken, or did we break it in a particular commit? If the
latter can you tell me which commit.
Should we be sending this to stable?

No. Let me grab a PowerVM box, test and get back.

memory_hotplug_max() got introduced in cd34206e9 and has been buggy since then.
Just that it got exposed by memory hotplug and DDW features on PowerKVM.

> Should we be sending this to stable?
I am not sure as only PowerKVM is affected with the introducion of DDW feature
in yet-to-be-released QEMU-2.7. Even there, we are working around the problem
within QEMU itself, but better to fix this in the kernel once.

Bharata.
