Subject: powerpc: use generic per cpu
From: Christoph Lameter <clameter@xxxxxxx>
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).
