Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc

Pull sparc changes from David S. Miller:
 "This has the generic strncpy_from_user() implementation architectures
  can now use, which we've been developing on linux-arch over the past
  few days.

  For good measure I ran both a 32-bit and a 64-bit glibc testsuite run,
  and the latter of which pointed out an adjustment I needed to make to
  sparc's user_addr_max() definition.  Linus, you were right, STACK_TOP
  was not the right thing to use, even on sparc itself :-)

  From Sam Ravnborg, we have a conversion of sparc32 over to the common
  alloc_thread_info_node(), since the aspect which originally blocked
  our doing so (sun4c) has been removed."

Fix up trivial arch/sparc/Kconfig and lib/Makefile conflicts.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc: Fix user_addr_max() definition.
  lib: Sparc's strncpy_from_user is generic enough, move under lib/
  kernel: Move REPEAT_BYTE definition into linux/kernel.h
  sparc: Increase portability of strncpy_from_user() implementation.
  sparc: Optimize strncpy_from_user() zero byte search.
  sparc: Add full proper error handling to strncpy_from_user().
  sparc32: use the common implementation of alloc_thread_info_node()
