commit 73ba26c1240a25e7699449e82cfc09dad10fed80

lparstat: Fix negative values seen while running lparstat with -E option
Negative values are seen while running lparstat with -E option.
This is because delta_purr value is less than delta_idle_purr.
Given that these values are read from different sources, a
small variation in the values is possible. So, in such cases,
round down delta_idle_purr to delta_purr.

lparstat: Fix offline threads uninitialized entries
When some threads are offline, lparstat -E is failing like that:

$ lparstat -E
Failed to read /sys/devices/system/cpu/cpu0/spurr
The message is complaining about CPU0 but the real issue is that in
parse_sysfs_values() the test cpu_sysfs_fds[i].spurr >= 0 is valid even if
the entry has not been initialized (cpu_sysfs_fds is alloc cleared). So
if the number of threads online seen in assign_cpu_sysfs_fds is lower than
threads_in_system, the loop in parse_sysfs_values() will read uninitialized
entry, where .cpu=0.
To prevent that, unset entries in the cpu_sysfs_fds should have the spurr
fd set to -1.

lparstat: report mixed SMT state
when SMT state is mixed like this one (CPU 4 is offline):
$ ppc64_cpu --info

Core 1: 8* 9* 10* 11* 12* 13* 14* 15*

Core 4: 32* 33* 34* 35* 36* 37* 38* 39*
Core 5: 40* 41* 42* 43* 44* 45* 46* 47*
$ ppc64_cpu --smt
SMT=7: 0
SMT=8: 1-5
ppc64_cpu --smt is handling that nicely but lparstat failed reporting the
SMT state:
$ /usr/sbin/lparstat
Failed to get smt state
System Configuration
type=Dedicated mode=Capped smt=Capped lcpu=6 mem=65969728 kB cpus=0 ent=6.00

0.02 0.01 0.00 99.97 3.41 56.83 0.02 0.00 4061778 156
Makes lparstat reporting "smt=mixed" in that case.
__do_smt is now returning 0 when the SMT state is mixed instead of -1 which
is also reported when an error is detected.
This doesn't change the call made by ppc64_cpu which is using
print_smt_state=true and so is expecting a returned value equal to 0 or -1.
With that patch applied, lparstat print that in the above case:
$lparstat

commit f4c2b0d142f623e7dd28a5d685e446d41be75601

lparstat: Fix display of mode for dedicated-donating partition
From the lparstat man page:
mode
Indicates whether the partition processor capacity is capped or uncapped
allowing it to consume idle cycles from the shared pool. Dedicated LPAR
is capped or donating.
However, on a dedicated partition, lparstat always displays the mode as
'Capped' today. Fix this by using 'DedDonMode' field from lparcfg for
determining the cycle donation status of a dedicated partition.
On a dedicated-donating partition:
$ grep -e shared -e DedDonMode -e capped /proc/powerpc/lparcfg
DedDonMode=1
capped=1
shared_processor_mode=0
Before this patch:
$ lparstat

After this patch:
$ lparstat
