[PATCH 9/9] ARM: fix kprobe test with CONFIG_CPU_32v3

[Arnd Bergmann]

ARMv3 did not have 16-bit load/store or 32-bit multiply instructions,
so building the kprobe test code fails with lots of warnings about
these:

/tmp/ccI4SKHx.s:19585: Error: selected processor does not support ARM mode 
`umull r0,r1,r2,r3'
/tmp/ccI4SKHx.s:19617: Error: selected processor does not support ARM mode 
`umullls r7,r8,r9,r10'
/tmp/ccI4SKHx.s:19645: Error: selected processor does not support ARM mode 
`umull lr,r12,r11,r13'
/tmp/ccI4SKHx.s:19727: Error: selected processor does not support ARM mode 
`umulls r0,r1,r2,r3'
...
/tmp/ccI4SKHx.s:21273: Error: selected processor does not support ARM mode 
`strh r0,[r1,-r2]'
/tmp/ccI4SKHx.s:21309: Error: selected processor does not support ARM mode 
`streqh r14,[r11,r12]'
/tmp/ccI4SKHx.s:21333: Error: selected processor does not support ARM mode 
`streqh r14,[r13,r12]'

This puts all the affected instructions inside an #ifdef section,
like we do for the other architecture levels.
