The patch titled
percpu: move arch XX_PER_CPU_XX definitions into linux/percpu.h
has been added to the -mm tree. Its filename is
percpu-move-arch-xx_per_cpu_xx-definitions-into-linux-percpuh.patch
*** Remember to use Documentation/SubmitChecklist when testing your code ***
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: percpu: move arch XX_PER_CPU_XX definitions into linux/percpu.h
From: Christoph Lameter <[EMAIL PROTECTED]>
The arch definitions are all the same. So move them into linux/percpu.h.
We cannot move DECLARE_PER_CPU since some include files just include
asm/percpu.h to avoid include recursion problems.
