Mark Nelson f72b728bf1 powerpc: Fix 64bit __copy_tofrom_user() regression ... This fixes a regression introduced by commit a4e22f02f5 ("powerpc: Update 64bit __copy_tofrom_user() using CPU_FTR_UNALIGNED_LD_STD"). The same bug that existed in the 64bit memcpy() also exists here so fix it here too. The fix is the same as that applied to memcpy() with the addition of fixes for the exception handling code required for __copy_tofrom_user(). This stops us reading beyond the end of the source region we were told to copy.
