Message-ID <[email protected]>
__percpu annotation of *cpu pointer in struct kioctx is put at
the wrong place, resulting in several sparse warnings:

aio.c:623:24: warning: incorrect type in argument 1 (different address spaces)
aio.c:623:24:    expected void [noderef] __percpu *__pdata
aio.c:623:24:    got struct kioctx_cpu *cpu
aio.c:788:18: warning: incorrect type in assignment (different address spaces)
aio.c:788:18:    expected struct kioctx_cpu *cpu
aio.c:788:18:    got struct kioctx_cpu [noderef] __percpu *
aio.c:835:24: warning: incorrect type in argument 1 (different address spaces)
aio.c:835:24:    expected void [noderef] __percpu *__pdata
aio.c:835:24:    got struct kioctx_cpu *cpu
aio.c:940:16: warning: incorrect type in initializer (different address spaces)
aio.c:940:16:    expected void const [noderef] __percpu *__vpp_verify
aio.c:940:16:    got struct kioctx_cpu *
aio.c:958:16: warning: incorrect type in initializer (different address spaces)
aio.c:958:16:    expected void const [noderef] __percpu *__vpp_verify
aio.c:958:16:    got struct kioctx_cpu *

Put __percpu annotation at the right place to fix these warnings.
