Subject: [ARM] vfp: make fpexc bit names less verbose
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=228adef16d6e7b7725ef6b9ba760810d5966afa5;p=linux-beck.git

[ARM] vfp: make fpexc bit names less verbose

Use the fpexc abbreviated names instead of long verbose names
for fpexc bits.
