Currently the ptrace-gpr test only tests the GET/SET(FP)REGS ptrace APIs. But there's an alternate (older) API, called PEEK/POKEUSR. Add some minimal testing of PEEK/POKEUSR of the FPRs. This is sufficient to detect the bug that was fixed recently in the 32-bit ptrace FPR handling. Depends-on: 8e127844 ("powerpc/32: Fix overread/overwrite of thread_struct via ptrace") Signed-off-by:
