Subject: random: Reorder struct entropy_store to remove padding on 64bits
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4015d9a865e3bcc42d88bedc8ce1551000bab664;p=mv-sheeva.git

random: Reorder struct entropy_store to remove padding on 64bits

Re-order structure entropy_store to remove 8 bytes of padding on
64 bit builds, so shrinking this structure from 72 to 64 bytes
and allowing it to fit into one cache line.
