Subject: powerpc/ptrace: Fix out of bounds array access warning

From: Khem Raj <[email protected]>

commit 1e407ee3b21f981140491d5b8a36422979ca246f upstream.

gcc-6 correctly warns about a out of bounds access

arch/powerpc/kernel/ptrace.c:407:24: warning: index 32 denotes an offset greater than size of 'u64[32][1] {aka long long unsigned int[32][1]}' [-Warray-bounds]

        offsetof(struct thread_fp_state, fpr[32][0]));
                        ^

check the end of array instead of beginning of next element to fix this
