Subject: entry: Move irqentry_enter() prototype later
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=eb1b51afde506a8e38976190e518990d69ef5382;p=thirdparty%2Fkernel%2Flinux.git

entry: Move irqentry_enter() prototype later

Subsequent patches will rework the irqentry_*() functions. The end
result (and the intermediate diffs) will be much clearer if the
prototype for the irqentry_enter() function is moved later, immediately
before the prototype of the irqentry_exit() function.

Move the prototype later.

This is purely a move; there should be no functional change as a result
of this change.
