[Bruno Nova <1328965@xxxxxxxxxxxxxxxxxx>]

I tested it too in Trusty.
Linux 3.13.0-32-generic from -proposed (used Synaptic to upgrade).
Package linux-generic version 3.13.0.32.38.

I can now do "sudo sysctl abi.ldt16=1" to activate 16 bit support.
Setting Windows 95 in winecfg now works correctly.
Old 16 bit executables now start correctly (tried Elifoot 98 on an older version of 32 bit Wine using PlayOnLinux).
Setting the option to 0 makes these issues return to the old behavior (as it should).

It was a short test, so I don't know if there are regressions elsewhere
or if the 16 bit executables still run exactly as before this problem.
But this issue seems to be fixed

@Ivan, to change the tags, look under the description of the bug, right
above "Related branches", and click on the "pencil" (edit) button. But
don't worry, I'll change it.

Title:
  3.13.0-29 kernel includes backport of 3.14 16-bit app restrictions but
  not override method causing wine win9x to fail

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed
Status in “linux” source package in Utopic:
  Fix Released

Bug description:
  Kernel 3.13.0-29 evidently contains a backport of the 3.14 kernel
  security workaround that disables 16-bit binaries from running.  This
  causes all wine Windows 95 and Windows 98 applications to fail.  The
  3.14 kernel also includes a feature to re-enable support for 16-bit
  binaries by providing the /proc/sys/abi/ldt16 interface.  This part of
  the kernel patch was evidently not backported, so this ability to
  override the 16-bit application prohibition is not available.

  For this reason, I cannot move forward to new kernel releases until
  this is fixed.
