The patch titled
sysrq, intel_fb: fix sysrq g collision
has been removed from the -mm tree. Its filename was
sysrq-intel_fb-fix-sysrq-g-collision.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: sysrq, intel_fb: fix sysrq g collision
From: Jason Wessel <jason.wessel@xxxxxxxxxxxxx>
Commit 79e539453b34e35f39299a899d263b0a1f1670bd ("i915: add mode setting
support") introduced a regression where you cannot use sysrq 'g' to enter
kgdb. The solution is to move the intel fb sysrq over to V for video
instead of G for graphics. The SMP VOYAGER code to register for the
sysrq-v is not anywhere to be found in the mainline kernel, so the
comments in the code were cleaned up as well.
This patch also cleans up the sysrq definitions for kgdb to make it
generic for the kernel debugger, such that the sysrq 'g' can be used in
the future to enter a gdbstub or another kernel debugger.
