Hi Riku,

mhh, personally I would prefer to see it in 2.7, too, given that it is 
just a bugfix. But it only makes sense with the patch that I've just 
posted to the mailinglist ("linux-user: ppc64: fix ARCH_206 bit in 
AT_HWCAP"). Therefore, if it is too late for the latter, the first might 
also be just scheduled for next.
