could the PowerPC maintainers please Ack the following patch (attached
below):
Subject: POWERPC: use generic per cpu
From: [EMAIL PROTECTED]
so that we can push this fix upstream ASAP?

Subject: POWERPC: use generic per cpu
From: [EMAIL PROTECTED]
Powerpc has a way to determine the address of the per cpu area of the
currently executing processor via the paca and the array of per cpu
offsets is avoided by looking up the per cpu area from the remote
paca's (copying x86_64).
