Heiko Carstens	1dcec254af	[S390] uaccess: implement strict user copy checks ... Same as on x86 and sparc, besides the fact that enabling the option will just emit compile time warnings instead of errors. Keeps allyesconfig kernels compiling.

Gerald Schaefer	6c1e3e7943	[S390] Use do_exception() in pagetable walk usercopy functions. ... The pagetable walk usercopy functions have used a modified copy of the do_exception() function for fault handling. This lead to inconsistencies with recent changes to do_exception(), e.g. performance counters. This patch changes the pagetable walk usercopy code to call do_exception() directly, eliminating the redundancy. A new parameter is added to do_exception() to specify the fault address.
