Subject: [PATCH 0/2] Remove -fno-unit-at-a-time and -funit-at-a-time compiler flags entirely


1/2: remove dead code, which is logically obvious
     because the minimum GCC version is now 4.6

2/2: we can say -funit-at-a-time is no longer useful
     according to GCC 4.6 manual

I hope, this series can be applied through x86 tree.



Masahiro Yamada (2):
  um: remove -fno-unit-at-a-time workaround for pre-4.0 GCC
  x86, powerpc: remove -funit-at-a-time compiler option entirely
