Cover letter [PATCH 0/4] Add generic ARM ISA condition code check
Quoted 10 lines · Will Deacon
Hi Leif,
Quoted 6 lines · Leif Lindholm
There are several locations in the kernel where software needs to inspect the condition codes of trapped instructions. The original bitmask implementation in the nwfpe code does this in an efficient manner. This series breaks this code out of nwfpe/fpopcode.{ch} into a standalone file for opcode operations, and contains additional patches to kprobes and SWP eumlation to use this interface.

Dave's been posting an
opcodes.hwhich seems to fit in with some of this, so it's definitely worth you guys syncing up if you haven't already.Dave - any comments?
Rather than risk conflicts, I will wait for Leif's patch to go into the patch system, and then I will rebase on top.
Cheers
