ARM: vfp: only clear vfp state for current cpu in vfp_pm_suspend
vfp_pm_suspend runs on each cpu, only clear the hardware state
pointer for the current cpu. Prevents a possible crash if one
cpu clears the hw state pointer when another cpu has already
checked if it is valid.

arm: vfp: Fix memory corruption on PM suspend
Commit
36af2a47 ("ARM: vfp: Always save VFP state in vfp_pm_suspend")
introduced a potential use-after-free bug. On SMP systems,
vfp_current_hw_state might hold dangling pointers in case a task which
used the VFP last migrates to another CPU and then exits. If
vfp_pm_suspend is called while vfp_current_hw_state still holds a
pointer to the freed thread_info, that memory location will be written,
potentially overwriting a new object allocated there.
The original problem is only relevant to UP systems in which the VFP
state is stored lazily.
Fix this by only storing the VFP state on UP systems, and avoid doing so
on SMP ones.

ARM: 7296/1: proc-v7.S: remove HARVARD_CACHE preprocessor guards
commit
612539e81f655f6ac73c7af1da8701c1ee618aee upstream.
On v7, we use the same cache maintenance instructions for data lines
as for unified lines. This was not the case for v6, where HARVARD_CACHE
was defined to indicate the L1 cache topology.
This patch removes the erroneous compile-time check for HARVARD_CACHE in
proc-v7.S, ensuring that we perform I-side invalidation at boot.
