Subject: core-parking: adjust data/code placement
X-Git-Tag: archive/raspbian/4.14.0+80-gd101b417b7-1+rpi1^2~63^2~2306
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=0e306f590ce7c713ac4ad018fd8c0b46ed8a018c;p=xen.git

core-parking: adjust data/code placement

Use __init{data,}, __read_mostly, and const as far as possible.

Take the liberty and also shorten the policy structure's tag name.
