Subject: ARM: 8920/1: share get_signal_page from signal.c to process.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=83dc1d99429af7d73225294f216a510ba6f58e45;p=openwrt%2Fstaging%2Fblogic.git

ARM: 8920/1: share get_signal_page from signal.c to process.c

The get_signal_page() function is defined in signal.c and used in
process.c but there is no shared definition. Add one in signal.h to
silence the following warning:

arch/arm/kernel/signal.c:683:13: warning: symbol 'get_signal_page' was not declared. Should it be static?
