Subject: ARCv2: fix local_save_flags
From: Vineet Gupta <[email protected]>
commit cd5d38b052384daa2893e9a1d94900d5a20ed4b5 upstream.
Commit d9676fa152c83b ("ARCv2: Enable LOCKDEP"), changed local_save_flags() to not return raw STATUS32 but encoded in the form such that it could be fed directly to CLRI/SETI instructions. However the STATUS32.E[] was not captured correctly as it corresponds to bits [4:1] in the register and not [3:0]
