Yeah, indeed.
I fixed that, PowerPC now looks like this:
irq time acct:-------------------------------------------.
THP:------------------------------------. |
gcov profile all:-----------------------------. | |
rwsem optimized:----------------------. | | |
queued spinlocks:---------------. | | | |
queued rwlocks:--------. | | | | |
numa balancing:-. | | | | | |
| | | | | | |
--------------------------------------------------------------------
powerpc | ok | TODO | TODO | TODO | ok | ok | ok |
