Subject: riscv: signal: fix missing prototype warning
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5c3aca86d2698c4850b6ee8b341938025d2780c;p=linux.git

riscv: signal: fix missing prototype warning

Fix the warning:
arch/riscv/kernel/signal.c:316:27: warning: no previous prototype for function 'do_notify_resume' [-Wmissing-prototypes]
asmlinkage __visible void do_notify_resume(struct pt_regs *regs,

All other functions in the file are static & none of the existing
headers stood out as an obvious location. Create signal.h to hold the
declaration.
