[Yakkety][[PATCH 0/1] Revert "x86/dumpstack: When OOPSing, rewind the stack before do_exit()"

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1627198

== Yakkety Justification ==
On bug reporters native amd64 box, all 4.8 based kernels boot just fine.  However,
on his VMWare Fusion 8.5 system, none of the 4.8.0 kernels complete the 
boot process.

After a bisect, it was found mainline commit 2deb4be2807 was preventing the
boot.  A 4.8 based Yakkety test kernel with this commit reverted will in 
fact boot.  However, when the VM boots, it gets the lightdm login, 
but it never gets to the desktop.  The system can be accessed by ssh.

A second bisect has been started due to this second and possible related issue.
The 4.8-rc1 kernel will boot without issue and get a desktop with commit 2deb4be2807
reverted.  However, v4.8-rc2 boots, but also fails to get a desktop.  Due to 
this, the second bisect is between v4.8-rc1 and v4.8-rc2 and commit 2deb4be2807
is reverted before each build during the bisect.
 
    
== Fix ==
A revert of mainline commit: 2deb4be28077638591fe5fc593b7f8aabc140f42.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel allows the system to boot.  However, there
is not desktop display.
