[PATCH] reorganize <linux/linkage.h>

[Kyle McMartin <kyle@mcmartin.ca>]

Commit 54a015104136974262afa4b8ddd943ea70dec8a2 adds some new magic
asmlinkage_protect gizmo, but that can only be used from C code, not
assembly. Protect relevant bits of <linux/linkage.h> with !__ASSEMBLY__
so this can't leak into assembly source.

Fixes a couple build errors on my boxes,
  AS      arch/parisc/kernel/pacache.o
In file included from arch/parisc/kernel/pacache.S:40:
include/linux/linkage.h:34: error: syntax error in macro parameter list
make[1]: *** [arch/parisc/kernel/pacache.o] Error 1

(__ALIGN gets used in both kernel and assembly context, so make sure it
is outside of the ifdeffery.)
