Subject: x86: make __{save,restore}_processor_state static
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cae4595764cb3b08f6517e99bac1e3862854b1a1;p=openwrt%2Fstaging%2Fblogic.git

x86: make __{save,restore}_processor_state static

.. allowing to remove their declarations from a global include file
(the symbols don't exist for anything but x86).

Likewise for 64-bits' fix_processor_context(), just that that one was
properly declared in an arch-specific header.
