The patch titled
Subject: kernel.h: split out instruction pointer accessors
has been removed from the -mm tree. Its filename was
kernelh-split-out-instruction-pointer-accessors.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Subject: kernel.h: split out instruction pointer accessors
bottom_half.h needs _THIS_IP_ to be standalone, so split that and _RET_IP_
out from kernel.h into the new instruction_pointer.h. kernel.h directly
needs them, so include it there and replace the include of kernel.h with
this new file in bottom_half.h.
