ARM: vfp ptrace: no point flushing hw context for PTRACE_GETVFPREGS
If we're only reading the VFP context via the ptrace call, there's no need to invalidate the hardware context - we only need to do that on PTRACE_SETVFPREGS. This allows more efficient monitoring of a traced task. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
