      fbdev: work around old compiler bug · 15e32524
      Stephen Rothwell authored 
      When building with a 4.1.x compiler on powerpc64 (at least) we get this
error:

drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict

This was introduced by commit ae52bb23
("fbdev: move logo externs to header file").  This is a partial revert of
that commit sufficient to not hit the compiler bug.

Also convert _clut arrays from __initconst to __initdata.

  Al analysed this some time ago.  When we say something is const then
  _sometimes_ gcc annotate the section as const(?) - sometimes not.  So if
  we have two variables/functions annotated __*const and gcc decides to
  annotate the section const only in one case we get a section type
  conflict.

      gcov: fix __ctors_start alignment · 2a2325e6
      Heiko Carstens authored 
      The ctors section for each object file is eight byte aligned (on 64 bit).
However the __ctors_start symbol starts at an arbitrary address dependent
on the size of the previous sections.

Therefore the linker may add some zeroes after __ctors_start to make sure
the ctors contents are properly aligned.  However the extra zeroes at the
beginning aren't expected by the code.  When walking the functions
pointers contained in there and extra zeroes are added this may result in
random jumps.  So make sure that the __ctors_start symbol is always
aligned as well.

Fixes this crash on an allyesconfig on s390:

      eventfd: revised interface and cleanups · 13389010
      Davide Libenzi authored 
      Change the eventfd interface to de-couple the eventfd memory context, from
the file pointer instance.

Without such change, there is no clean way to racely free handle the
POLLHUP event sent when the last instance of the file* goes away.  Also,
now the internal eventfd APIs are using the eventfd context instead of the
file*.

This patch is required by KVM's IRQfd code, which is still under
development.
